Having fun with my Boyfriends sister

A sexual experience I had when I was younger is one I often return to when I want to slip into the Zone. I was at university in England and dating a guy. His student flat was badly heated and so we often just spent the entire time we were together in bed watching TV. The time in question was when his younger sister came round to visit and, after a night's drinking with the pair of them, I went to bed with my BF whilst she settled down on the couch. The night was very cold and she only had a thin blanket over her and, despite her bravado, I knew she was uncomfortable. I suggested to my BF that she could join us in the bed because it wasn't really right that his sister freeze her ass off on the couch and he drunkenly murmured that it was OK before drifting back off into a cider coma.

His sister was very pleased to be somewhere warm and as she lay down next to me in the bed, I turned away satisfied that I'd done the right thing. Then an incredibly kinky thought crossed my mind. There she was in the same bed as her brother lying next to his girlfriend who - unbeknownst to her - was secretly longing for more than just dick in her life. If I made a move on her - how would she take it? And would she be less likely to turn it down, not wanting to cause a scene? I decided to see how far I could get. So I turned so I was facing her. She remained lying on her back and didn't turn over which I took as a good sign. Pretending I was asleep I casually moved my arm so my hand gently brushed her bare leg (she was only wearing panties) but done so subtly that it could just have been misconstrued as restlessness.

Again she didn't move away - in fact she remained stock still. I decided to push the limit of ?accidental touching " and repeated the action but left my hand lying against the flesh of her leg. Rather than move to give me more space, she once more remained still. My breath quickened as I felt her warm leg against my hand.

Dare I move it now and cross the line? Gathering all of my courage, I extended a single finger, stroked her leg, and then returned to my previous position, hardly able to breathe from the tension. Seconds seemed like hours. Again no reaction. Thinking she hadn't felt it, I bit my lip and stroked her leg once more - this time making a letter S with my nail. My boyfriend momentarily stirred and I feared she would turn away but he went straight back to sleep. Now I was at a complete loss as to what to do. She hadn't either accepted or rebuffed me - in fact she had acted as if nothing had happened but remained in a position that suggested she was open to more. I decided to go for broke. I stroked her leg and then instead of stopping, continued stroking in circles which slowly rose so they were tracing the line of her leg. My stomach in complete knots I continued to trace the line of her leg until I was at the outer rim of her panties. Now there was no doubt as to what was happening. All she had to do was move and I would have stopped but instead she lay there motionless.

Reeling from butterflies, I edged slightly towards her so I could continue the journey I was determined to finish, and moved my hand down until it reached her inner thigh. Convinced she would now stop the game, I was blown away as she opened her legs slightly to let me through, my hand now tracing down across what felt like an incredibly hot pussy beneath the fabric. Then as I moved to pull back the fabric and go beneath, her hand blocked mine. "Its ok if you want me to stop,? I reassured her with a whisper. "No, I just want to make sure you'll be gentle." I looked over my shoulder where my boyfriend was flat out drunk and stroked her hand with mine. "Is this your first time with a girl?" I asked. "No,? she whispered, "This is my first time with anybody." Slowly she took my hand and let it slide inside her panties. Instantly I felt the heat of her pussy greet my fingers. "Oh," she immediately jumped as I made a tentative move forward. What's wrong? I asked -hoping she wasn?t going to be quite this sensitive otherwise we wouldn't be getting anywhere. Your hand is cold, she replied. Reassuring her it would change, I ran my hand down to my own pussy - now simply liquid at the thought of this virgin young thing- and placed my fingers inside. Hmm, they were a bit cold but after a few seconds they weren't any longer. I then moved them back to her pussy and she relaxed with their new warmth as I slowly stroked her in a downward motion, briefly moving her moist lips apart with my own juice. I shuffled slightly over in the bed, resting my head on her shoulder and kissed her on the mouth. The angle was awkward but she turned her head to meet mine and soon we were kissing fully - a situation I used to mask her first penetration with my fingers.

Kissing her deeply and fully, I pushed my fingers against the resistance of her pussy which, although tense at first, soon popped and gave in as I slid inside. Katie shuddered and went to move her head away in discomfort but I continued my kiss so her sounds didn?t wake her brother. It?s ok - it?ll feel better in a moment, I reassured her and, soon enough, the natural sensation of having something inside her pussy stimulated its natural lubrication and she began to relax. Soon my fingers were able to move effortlessly inside her, eliciting small moans from Katie as she dug her nails into my shoulder. Giving her a break, I removed my fingers, put them to my mouth and licked her pussy from them. Damn, it was actually sweet! Cursing myself for not thinking this through, I became frustrated - I was now so turned on by this girl, that all I wanted to do was fuck her senseless but I couldn?t in case her brother woke up.

Checking he was still asleep, I decided that if I was going to do anything I had to at least get a proper taste so I gingerly moved over to where she lay. ?Won?t this wake him up ? ? she asked in a worried tone but I reassured her that he was flat out ? something I wasn?t entirely convinced of myself but by now I HAD to get a taste of that sweet pussy despite the risks. I quickly moved her legs aside, moved over between her thighs and with one eye on where he lay - buried my face between them. It was an incredibly dangerous move but boy was it worth it. Needless to say my intention wasn?t to do it for very long because the sight would have been unambiguous to my BF if he?d woken - I was licking his sister out and she loved it. However, I was so aroused by her scent that I momentarily forgot where I was and just kept on licking, sucking and French kissing her till her juices covered my face. Soon the bed was bouncing from Katie?s writhes of pleasure and I had to raise a hand to muffle her moans which were becoming very audible. Suddenly a movement in the bed made me freeze.

My BF had woken with a start. Quickly I moved back over to my original position as he turned over to face my back.

What?s with all the wriggling? ? He asked. Can?t get comfortable, I complained in reply. This seemed to placate him and he shuffled back to sleep but just as I stroked Katie?s leg, he leant forward and whispered in my ear, I?ll make you comfortable, and pushed his pelvis into my ass. I didn?t reply, hoping he would get the message that I wasn?t interested, but he didn?t and started to run his hands over my boobs and ass. He then pulled up my night shirt and pulling my panties down, roughly pushed his fingers forward. ?Christ, you?re wet, ? he whispered as he penetrated me with his thumb. All the while this was happening I could see Katie lying next to me looking at the ceiling and I longed instead to be with her. However, this moment was instantly interrupted by the feeling of his cock pushing against my thigh as he tried to take me from behind. I moved it away and angrily whispered in a harsh tone, I know you?re not gonna try and fuck me with your sister in the bed.

My boyfriend thought about this for a moment and guilt-tripped withdrew. But I?m so fucking horny, he complained. Ok, I?ll see what I can do, I replied, but for Christ sakes act like your asleep will you, it?s not right with her here. Slyly laughing to myself as he pretended to sleep, I leant over to Katie, You ok? I asked audibly so my boyfriend could hear, before softly whispering in her ear, We can still do stuff, but it?ll have to be quieter ? pretend you?re asleep and I?ll make you come. Katie leant closer into me so our bodies practically touched and I continued with one hand to stroke her pussy and clitoris. As I did this my boyfriend pushed his hips forward and I lay on my back so I could also jerk him off. It was incredibly awkward at first but somehow a rhythm generated and soon both were writhing on their prospective sides of the bed, Katie putting a pillow over her face to stop her moans, my BF moaning into his pillow ? neither of them aware of the other?s pleasure because they thought the movement of the bed was due to them. My Bf however wanted more and pulling my hand away, grabbed his own cock, an action which shocked me into letting go of Katie. Now heavily excited, he started to masturbate himself. I?ll do this ? I just have to touch you as well, he declared reaching over, so deliriously into his impending orgasm that he was just groping about in the dark. Man you feel fucking great, I heard him say. So, fucking hot ? a statement that struck me as bizarre considering he wasn?t inside me. Then, as I heard a muffled moan from Katie, the truth dawned. My BF in his blind groping was finger fucking his own ? completely unaware - sister. I didn?t know what to say or do and instead lay there frozen listening to their frantic motion as both plateau to orgasm, Katie coming with a little muffled cry, my BF shooting his load all over my back. Instantly he withdrew his hand and turned to lie on his back, giving me a moment to lean over and check she was ok. Thanks, she whispered kissing me on the lips sweetly, that was unreal. I kissed her in return and tucked the blanket around her as she turned away. Dabbing my BF?s come from me with a handkerchief I turned to face him and found him, licking his fingers with delight from where he?d been touching Katie, Don?t know what it is, he announced But you taste great tonight. I leant forward and sucked her flavor from him, giving a sly look towards Katie. Yeah, I replied grinning, best pussy I?ll ever have."
