Girlfriend Falls For My Best Friend

About 15 years ago I was dating a girl I loved very much. We were starting out on our own, and had my girlfriend's sister living with us as well. We got on the internet to chat with people regularly, nothing sexual, just chatting. We met a really nice guy having hard times that lived in another state. His wife divorced him, he wasn't seeing his kid, really down on his luck. So we decided after several months of chatting and talking on the phone that we would let him come live with us. So after we made sure the new milennia didn't kill anyone, we paid for him to get out here.

The first several months were great. He had his own room, the sister had her own room, and me and my girlfriend had our own room. I don't know if my girlfriend's affections for me were wearing off, but we started spending a bit less time together so that she could talk to my best friend about how she felt, and about his life in his home state, etc. I would spend hours on end waiting to talk to either of them, but they both stayed in his room talking. Nothing more...just talking.

Then one night I am given the task of running to the store for cigarettes for all of us. "Why don't we all go?" I ask, but they don't want to. So I sneak out for the cigarettes and drive at breakneck speeds, getting back within 7 minutes from the mini mart and parking along the road on the next block. Then I run back to the rear of the house, through the basement and up to the main floor. I'm shattered. I stand in the dining room and light a cigarette, standing directly under his bed, where I can hear every little strain of spring, creak of the bed, and gasp of their raspy voices.

Being the cuckold that I am made to be in this life, I have my cigarette in one hand and my dick in the other, doing a combination of smoking, jerking off, and crying. Not paying much attention, the sister gets home from a school dance and pops in the front door. I can only imagine what went through her head...I'm on my knees with a cigarette in my left hand. My pants have been pulled to my ankles, and my shirt front pulled over the back of my head. I am crying like a baby and beating my cock, while sounds of a porno shoot wafted down from overhead.

I can tell you it shocked me that she felt sorry for me. The sister who didn't talk much to me came over and got on her knees with me and hugged me. I don't know why, but I broke down even more. And to top it off, I don't know if it was the sound of her sister and my friend hitting it hard, but her hand replaced mine. My hand, slick with precum, slid across the side of her bare middrift, leaving a trail of ooze as I grabbed her waist for support. In the dim light of the upstairs hall light I could see her face. I really looked at her, and could see the change from studious teen to naughty vixen wash over her. She is pumping my cock with her left hand like she is churning butter, and with her right grabs my left hand, takes a long draw on my cigarette and says in my ear, "I always wanted a big brother."

I don't know what her intent was, but in seconds I shoot loads of cum down the front of her....her tank top, belly and cut-off shorts get the brunt of the attack. Spent physically and emotionally, I collapse on my side onto the floor. She joins me and takes my cigarette as her own. After two exhalations, she leans up and takes my dick to the base in her mouth, startling the crap out of me. After swirling it around in her mouth a moment, she comes back down and kisses me. This deviant girl has started me on a path that will mar my relationships for the rest of my life. And she never told her sister anything.

But after that night, they spent too much time alone in his room. Two months later my girlfriend was pregnant, even though we hadn't had sex more than twice since this encounter. She actually called herself my girlfriend until a few months after their baby was born, then they kicked me out of the house.

So I lost two good people to each other.
