My 18th Birthday Family Vacation

Last month I had my 18th birthday, it was the day that might have changed me forever!

I am the youngest of 5 children and the only boy in the lot. The oldest Cathy she is 23 years old, married with a new child a year old the next oldest are the triplets, Kari Mari and Teri all three are 20 years old Kari and Mari are in college upstate, and I live with Teri in our family home our parents were killed when I was 15, in a vacation accident Cathy still lives in town and she took over the family and raising me till she had gotten married and the triplets took over,

About a month before my birthday, Teri said the family was planning a trip for my birthday just being out of school, graduated heading off to college myself in the fall. I thought this summer vacation would be fun. A couple days before my birthday trip, the other triplets showed up; I had not seen them in close to a year. It seemed I could always tell which twin was who.

But now I had to do a double take I wasn’t sure which one was who, in that year they had grown their hair long and blonde one had her hair up in a loose bun and the other in two ponytails our mother had for site when the triplets were born she left the hospital tags on the girls and had a tattoo artist put a single letter for each name they were put just over their butt tiny but there enough for mom to keep tract. Now I knew which was Teri even though she looked the exact same she had chosen to dye her hair auburn a couple years ago.

Cathy she was elegant tallest of the siblings (the triplets were 5’4” i am 5’8”) she was 6’ 1” she had long shiny silky black hair when it was not up in a bun it reached to just above her ass. The triplets and I were all catching up on last year apart. Mari, who was one of the cheerleaders at her university was complaining she couldn’t find the right guy the Teri and I had chuckled however Teri, nor I had found anybody either. The next morning i was woken up by Kari, she told me Cathy had arrived her husband was dropping her off for the week we were going to be away then he was taking their kid to his parents as he had a trip out of town for business

Cathy was spectacular she arrived in a loose-fitting tank top covering her tight belly and a pair of cut-off jeans her breast still swollen from breast feeding she had told the triples later she had only stopped feeding a couple weeks before but was still pumping and storing it in their freezer for later use. However, she thought this trip would help her finally dry up. the next morning, I got up as we were going to be heading to the airport in a couple hours, I got up almost forgetting we had house guests and blindly walked to the bathroom and was shocked to find Cathy standing at the sink except for a pair of panties she was naked from a shower her long black hair being combed.

I stopped in shock Cathy smiled into the mirror and said good morning sleepy, I was backing out when Cathy told me to don’t worry come on in I’ll be out of your way in a bit I mumbled no I could wait to pee, Cathy said nonsense, I’ve seen your penis before and I live with a man you have got nothing I have never seen before.

I shrugged and went to the bowl and flipped the lid up and started to relieve myself Cathy let out a small giggle; Wow, Bradley I don’t recall seeing that thing she stared into the mirror right at my semi hard cock soft i was about six inches long and looking at other guys in the school showers i was kind of thicker than most I blushed she laughed looking at my reddening face and walked out of the bathroom, i was quickly hardening thinking about Cathy’s tits easily still double ds her nipples standing out proud and hard her tits looked as firm as the other girls did. Although the only others I had seen were Teri’s naked as I accidentally, maybe on purpose walked in on her in the shower.

I went down to the kitchen after getting dressed and found the triplets down there getting breakfast ready, they were all dressed alike of course Teri had her flowing auburn hair I couldn’t tell which was Mari or Kari, so I went to the closest and pulled the back of her shorts down and looked for the letter...ah, Mari I noted she had rather lacy red panties under her shorts she turned and grinned said I was wondering if you could still tell.

Mari then showed me on her neck she had grown a small freckle Kari didn’t have she said now I didn’t have to de-pants her to see which triple she was, I nodded and said I preferred the other way she giggled you always were a bit of a pervert!

The car came and picked us up and we left to the airport the women going over every detail checking passports did we turn off the lights and in general talking about the trip. Jamaica, I couldn’t wait! Hot beach sands warm water the food! And beaches full of hot young women in all states of dress I read up and found out most beaches were nude beaches it made me hard thinking about it.

Cathy caught me trying to adjust myself and gave me a slight grin knowing I was hard. The flight was smooth except I was still hard I got it to go down and headed to the rear bathroom I needed to jerk off to get my cock under control imagining seeing all those naked women on the beach was enough to shoot a hard load into the toilet of the plane.

I returned to my seat next to Cathy she put a hand on mine asked if everything was under control i said yes, the coffee had was making me pee, she smiled patted my hand and returned to her tablet i looked at her tablet and noticed she was looking at pictures of sandy beaches with naked people walking around the picture she was looking at the longest had a guy with a firehose hanging down to his knees I nudged Cathy she grinned and whispered a girl can dream cant she? We landed and got our belongings and went to our condo it was a three bedroom, one for me one for Cathy and one with bunkbeds for the triplets it was early evening and the triplets announced they were famished and wanted to go to a restaurant the driver had told them about it was walking distance it was the best food I had ever eaten!

That night the triplets said they wanted to go dancing and bar hopping I was still too young and Cathy had given up drinking, so she and I stayed in, and the triplets got changed and went out, I found a movie to watch and Cathy said she was tired and was going to turn in the movie was one i had seen already so i was looking at my phone when I heard a noise and got up to investigate

The noise was coming from Cathy’s room I peeked in she was naked on her bed holding her tablet in one hand and had a sex wand in her other I was transfixed, I knew I shouldn’t be watching her but I couldn’t walk away she never took her eyes from the tablet screen the wand humming fast and loud her breaths coming in short gasps breathing faster and faster suddenly she closed her eyes and dropped the tablet to her side and moved her empty hand to her tits I noticed they were leaking milk it was running down the sides of her tits to the bed below she closed her legs and held the wand in place bucking her hips slowly up and down he body suddenly started spasming he legs fell open milk was spitting out of her fingers and when she moved the wand a great gush came out from her legs so hard it almost hit me Cathy was trying to keep herself quiet as she could.

I stood there watching her pussy I could see it clenching in every spasm, I heard a moan and then a high-pitched scream my eyes shot up to her face Bradley what the fuck!! You little pervert. I turned and ran out of the room as the wand hit the floor behind me, stopping short because of the cord attached to the nightstand outlet.

I went straight to my room and closed the door knowing Cathy was coming in to kill me for watching her. And sure enough, a couple minutes later Cathy opened the door standing there with just a pair of black panties and a small silk robe on her hands on her hips. The robe I could see over her tits was getting two wet spots on it.

Bradley, you should know better than to sneak up on a woman and even more to sneak up on your sister while she is...well she sputtered you should know better! Oh Cathy, I'm so sorry it is just, I never seen...a woman...I’ve never seen a woman cum before I couldn’t help it! Bradley said Cathy. Not even my husband had seen me doing that after a minute she seemed to calm down a bit you have never? I shook my head not ever...surely you live with Teri you have had to see her...nope never I said I had walked into the shower and accidentally caught her naked but that was all i saw. Have you seen a girlfriend doing it?

No, I said quietly, are you still a virgin? I slowly nodded yes, not able to look at her in the face, well that makes perfect sense. Cathy came to my bedside and sat down close. I could see the milk trails from her nipples. She said it looked like from your face I had scared you;

You want to talk about it? If you don’t mind, she said sure I asked her why she was doing that being married. She told me her urges didn’t stop because she was married. And the pictures she had seen on the plane had her excited, I nodded remembering the guy with the giant cock, you mean like the guy with that big dick? Cathy blushed and said yes honey that guy especially it was because he reminded me of yours, I was a bit stunned forgetting she had seen mine that morning in the bathroom, she went on, it is huge, and my husband is a great provider and I love him with all my heart, he was not blessed with a cock like yours and seeing it today made me wonder what I was missing out on.

Cathy went on to say the idea of such a huge cock made me horny, and if you had not come in, I would still be riding my vibrator right now. I looked into her eyes and could see she was still hot, Cathy, would you like to see mine again? She smiled and put a hand on my arm. Her hand still wet from the milk still in it, no Bradley that wouldn’t be right. I am married and I am your older sister. It just wouldn’t be right, my face dropped I get it I said but maybe if you wanted to I wouldn’t mind and I would not tell anybody, she looked at my face lifted it to hers I could see her eyes welling up she grabbed my head and pulled to her chest

Oh, Bradley! You are the best brother! And she broke out in tears i was not sure why but i did notice my face getting damp from her tits still leaking i felt a nipple on my cheek suddenly I turned my head and pulled her nipple into my mouth I started sucking on the nipple and was rewarded with long sips of fresh breast milk she gasped but didn't push my head away she started running her hand around the back of my head gently cooing to me as I suckled her mother's milk as this went on she moved my head to the other side and said now we Gott' a keep them even!

As I suckled, she started moaning softly, finally she pulled her tit out of my mouth and said, that should take that pressure off I was needing to pump it out but left that at home. She went on; I could never get my husband to do that; I told her I was glad to help. She smiled, turning a curl of my hair in her fingers and said you might be doing that again if you don’t mind, I laid back in the bed and Cathy laid back on the bed also.

I could sense it more than anything more but i saw her hand going to her panties well that had never happened before she said she had completely soaked her panties she grabbed me by the hand and put it to her panties, they were wet! She went on, if my husband was here, Well Cathy, I would be happy to stand in for your husband!

She looked at me and stopped talking, i could see her face working something out, Bradley, we can't do that, sucking my milk is one thing but fucking, I couldn’t, Cathy I said really i would love my first time to be with you! She looked me hard in the face, Bradley I would love that but if my husband Hey we can do the Vegas thing what happens on the vacations forever stays on vacation she thought about it and then she reached down and hooked her thumbs on her panties and started pulling them down Bradley do you know how to eat a pussy?

It was beautiful up close the heady smell of her pussy the glazed wetness covering her vulva and her thighs the thick bush of black hair wet with her sweat and juices Cathy pulled my head towards she pussy and said it is time to teach you how to satisfy a woman.

With Cathy guiding me giving directions i set about to eat my first pussy a woman's pussy once i got the hand of it all I could hear was increasingly dirty talk and lots of moans her hips slowly grinding onto my face her juices running down my chin and following my neck I had a hold on her hips her legs over my shoulders wrapped around my head.

OH BRAD! She breathed OH GOD! OH FUCK!! Her breathing became short and fast. Suddenly her legs started squeezing my head, her fingernails digging into my hair she grabbed huge clumps of my hair she body began shaking and then her breathing stopped and she yelled, SHIT!!! It is happening! her body went into spasms I was trying to keep my tongue on her clit like she told me she suddenly pushed my head out of the way her fingers began rubbing her clit hard and fast I was coated as he squirted her breaths coming in almost huge gulps of air her and still had my hair and she pulled my head back to her cunt bucking and smearing my face my tongue touched her clit and her body suddenly went ridged OH MY GOD!! AGAIN! Don't stop Bradley don’t stop it went on for what seemed like minutes finally her legs loosened and she let my hair go I moved out of the way she covered her pussy and tuned on her side, oh my god what have I done!

Oh, Bradley, can you ever forgive me? I couldn’t help myself nobody had ever done that to my pussy I couldn’t stop it was so big! Never have I cum like that, she turned and looked at my face, you can't ever tell anybody...Oh Bradley I'm sorry how insensitive of me you have not gotten off have you? She sat up and pulled my shorts down my throbbing cock springing out Bradley, this is huge! She smiled and asked had I ever gotten a blow job before I could answer she pushed me into her mouth trying to open it wide enough to suck it all in I could feel her tongue rubbing around the head of my cock it was wet and warm in her mouth the soft suctioning of her lips she too hold of my balls and started to rub them her fingernails drawing traces around each ball it was all I could take I said I think I am going to cum, Cathy shortly said in my mouth honey I felt the flood gates break I watched face and she swallowed ribbon after ribbon of cum she was trying hard to keep up with the explosion I could see drips leaking around my cock from out of her mouth.

She looked up wiping some of the escaped cum back into her mouth, she grabbed me and kissed me pulling me on top of her I moved between her legs she stopped kissing and said I’m sorry Bradley, I can’t help myself I grabbed me still hard cock and rubbed it around in her bush before slipping it down her slit my head getting coated with her cum i rubbed it around on her clit then pushed myself towards her waiting cunt. I could feel her lips parting surrounding the head of my cock it was tight she said slowly now Brad; I have never had such a big cock inside me before i started pushing slowly feeling her pussy parting and suddenly i was buried up inside her. her eyes open wide her mouth opened in a silent gasp i felt the end of her canal as my cock head bounced off it

She put her hands on my hips and said slowly big fella go slow I sat there not moving till she got used to my girth I could feel her pussy gently quivering she finally nodded alright go slowly I got to get stretched open I slowly pulled it back out and then pushed back inside steady slowly i could feel her cunt relaxing before long we were fucking like sex starved nymphomaniacs Cathy moaning loudly every stroke into her pussy touching the back she would let out a sharp squeak before much longer her legs started to tighten around my waist and hips I could feel her cunt tight around my ramming cock she grabbed my head shoved my face into her tits i started sucking them hard drinking shot after shot of her milk her head was rolling from side to side she again stopped breathing and held me inside with her legs hooked behind my thrusting ass and she came hard my cock buried my balls resting on her wet ass.

Wave after wave ran over her body, I could feel her cunt clamping down. It was more than I could take I exploded deep inside her pussy filling her up with my second load of the evening. We both kept fucking till my cock got soft and fell out. Cathy pushed me off her belly and ran to the bathroom. I was spent, Cathy was in the Bathroom for a while, i walked in to pee she was sitting on the side of the tub her hair was wild and sweaty her face reddened she looked up at me Bradley, we should have never done that! I asked if she was having some regret, not really except my worry I will never be satisfied with my husband ever again. I didn’t say anything," she said. "I’m sorry, but I am going to have to re-play that with you again while I figured out how to solve this problem. With that she stripped off her towel and turned on the shower as she entered the stall, looked over my back and said, "are you joining me? We need to wash all our cum off your body.

As we cleaned each other off we talked about what had just happened it was decided when we got home, we would not do it again, but Cathy said that might not last long. As she really loved being stuffed full

The next morning Teri was standing over me, her hands full of clothes. Get up, Brad. I sat up, rubbing my eyes. I looked at Teri. She was holding Cathy’s panties in her hand. I could see they were still damp. What are these doing in your room? Holding out Cathy’s panties just then Cathy came into the room in a bright yellow one-piece bathing suit she took them from Teri, and said she had used my shower and had dropped them on the way to her room

Teri seemed o.k. with the explanation. Cathy asked where the other girls were Teri said still out, I think they got lucky. Cathy smiled, "what about you sis? Teri said nope, I'm still a virgin, not ready to do that yet. Cathy smiled at me and put the panties back on the pile in Teri’s hand after Teri went to the laundry. Cathy said she needed to go to find a pharmacy. She did the math last night and was sure we had made her pregnant and that she should get a plan B. and she left.

Just after that Teri came into the room, she said she didn’t really believe that crap she dropped her panties and what had really happened, I looked her straight in the eye and said Cathy and I had fucked each other's brains out. Teri looked stunned but then broke out into a hearty laugh.

If that were true, I would HAVE to be next! As she said it, she looked at me...in shock, YOU FUCKED CATHY!! Oh, Brad! How was that? Trying to decide if I was going to admit to Teri, I had really fucked our sister Cathy came into the room and said i forgot...what the hell Teri turned to Cathy you fucked Bradley? without missing a beat, she said I did, and it was great have you ever seen his cock?? Teri with her eyes big and her mouth open...said no I have not. Cathy held her two index fingers apart and nodded yeah that big now I must go get a plan B if you decide to try it with that tiny virgin pussy of yours you best be careful!

Cathy left the condo I sat there with Teri staring at me. I can’t believe what I heard! Are you really that big? That was not what i had expected to come out of her mouth. I nodded it is true I said her eyes burning into mine. She shifted her eyes downward i asked “You want to see it?"

Just then Mari and Kari came in the door, Teri mouthed “later” The triplets all left to their room to get bathing suits on to go to the beach. Just as we were leaving to go to the beach Cathy came home with a small bag she asked if we were going to the beach Mari and Kari both sang out yes, we are! We can’t wait! Cathy said hang on, I must get a drink before we go, and I want to go with you guys!

On the walk to the beach about 2 blocks away Cathy walked with me she said she had taken her plan b. and now it was a wait for her next period to start hopefully in 2 weeks now she asked me how Teri was acting after she had left I told her see seemed fine but horny,

We all got to the beach and everywhere I looked people topless and people nude lots in the water, i was shocked seeing so many tits and cocks bouncing in the warm summer breeze we found a place and started putting down towel to lay down on I heard Mari tell Kari if you do i will i turned to see them both pulling their tops off.

Both women had nearly the same tits b cups pure white skin with pale pink nipples both hard pointed slightly up on their tits my cock began stirring with all the flesh and the girls tits, when i looked back both girls were pulling their bottoms off I could see the small letters above their fine asses Mari turned to put her bottoms on her towel I saw she had shaved her pussy smooth, Kari turned and I saw she still had her blonde bush neatly trimmed but not so thick as Cathy's bush the girls applied sunscreen over each other's bodies then turned to head to the water. Teri pulled her tank top off she didn’t have a bikini top on she asked me if I would rub sunscreen on her back, I agreed I rubbed her back with sunscreen moving my hand closer to her sides and more towards the sides of her tits when it took my hands off she looked back and said her tits were going to burn as long as I had my hand covered in sunscreen I should finish the job I turned my head toward Cathy, she grinned and said you started the job. As i rubbed Teri’s tits with lotion she began moaning softly her nipples hardening under my hands and fingers.

The day dragged on, and Mari and Kari came back and said they had met a couple men and they were going to the bar with them and put their bikini bottoms back on and gathered their bags and headed toward some guys in a group we three decided to go back to the condo when we got their Cathy took off her bathing suit in the front room and announced she was going to take a shower then go into the village to find me a birthday present.

She asked if Teri was going to go with her, she said no she had already brought one with her Cathy nodded and told us I will see you later and she told me to be careful.

I looked at Teri, and she was grinning like she got picked for the lottery. After Cathy left Teri came over to the couch were i was running through the movie channels, she took the remote from my hand and said YES! I do want to see it! And she stood up and pulled her top off and started sliding her shorts down her panties were flowery and pink I reached out to help her pull those off she brushed my hands away not until I see what I’m planning on getting I smiled and stood up she grabbed my shorts and tugged my now hardening cock sprang up and hit her in the chin she jumped back and grabbed it her voice became shaky oh my god Bradley Cathy took all of that?? I nodded. She took a couple steps back and slowly started pushing her panties down when she stood up straight i could see an almost exact match to Kari’s bush just as blonde and just as neatly trimmed Teri moved in closer grabbing my hard cock and started kidding the crown of my cock she licked from the bottom to the top she looked up at my eyes and said if I am doing it wrong tell me I watched Keri once with her boyfriend during high school she looked back down and slowly sild my hard cock into her mouth she gagged a bit as it hit her throat but she kept pushing it in till I felt is slide down her throat. It was an amazing feeling she started taking long strokes up and down my cock disappearing down her throat it was starting to take its toll I pulled out of her mouth and said here lay back let me show you what Cathy taught me.

She nodded I spread her legs she was very pink inside her pussy lips I could see her clit pushing itself out of its hood as I lowered my face towards her cunt she put a hand on my head, what are you doing brad? I grabbed her wrist and moved it to her belly and pinned it there and pushed my face into her pussy my lips and tongue searching for her clit I slowly licked my tongue up from her ass to the bush my tongue at the last second bypassed her clit she back had already began stiffening after a few more teasing licks i landed right on top of her clit she moaned loudly I started working on her clit she started bucking slowly raising her hips to meet my next pass her hands moved to her tits and she started rubbing then pinching her pink nipples making them both bright red.

Teri was moving in stride with each of my licks until to suck her clit into my mouth she froze inside my mouth I was beating that clit as hard and fast as my tongue would go gently holding it on my mouth with my teeth OH SHIT Bradley her hands grabbed my shoulders she back came up off the bed pushing her cunt as far in the air as she could her orgasm hit hard she was throwing her hips from side to side up and down she was on fire i had my hand under her ass to help hold her up but my finger slide into the valley of her clenching ass and found her little pucker my finger tip stopped on it and i pushed it into her ass she started cummings again when it was over i had my entire finger shoved into her ass and my thumb buried into her virgin pussy her body relaxed still quivering her belly heaving her breath slowing she looked at me and said wow that was the best I ever had she pulled me up on her body and gave me small pecking kisses i noticed i could feel the head of my cock pushing on her pulsing cunt.

I felt it was right over her opening i pushed a little bit the contact made Teri jump, but she didn’t panic I pushed it a bi further meaning to stop long enough for her to get used to me but it didn’t stop it slide in smoothly to the balls she smiled and said what you thought it was going to be a fight? I have had a dildo since I was 17...she said now fuck me with that big tool we fucked long and hard she was cummings almost the entire time one right after the other I was ready to cum, she was in the middle of a big one and my cock just started drain itself into her pussy coating her cervix with goo, after a while we both returned to the land of the living my sliding out of her with a loud plop she was giggling giddy with afterglow

I sat up and there was Cathy sitting on the chair. Her hands crammed down in her panties she spoke between heaving breaths. Now that was a show! Teri looked at her and said that it was great. I am not sure why I waited so long for that. Cathy said i have another plan B for you i guessed you might need it. Teri said good I think I might also be ovulating too the rest of the week was the greatest birthday ever taking turns between Cathy and Teri we all flew home and when we got home Cathy kissed me and said not one word and sadly, we can't keep doing this together of course Teri and I bought a king bed for my room and continued on having great sex about a week and a half after we got back Cathy came by told me she had gotten her period and things were good i said Teri had also gotten hers and was making a trip to her doctor for birth control she said so you guys are still fucking? I nodded yep sure are, good she said she told me her husband was out of town.

Cathy came over to me and opened her button up dress and I just finished my period.

Life was great indeed. We were still fucking when Teri came home, she sat on the chair in my room as Cathy and I took each other to more hot orgasms. She said out loud, it is wild to watch you two fucking like teenagers.
