I am 23 years old and my girlfriend is 20. We live together in an apartment and she has family visitors staying the night on a regular occasion. All of these visitors are her sisters. Only ever one at a time though. Her youngest sister is only 14 years old. Her body looks much older though. She has huge tits. I believe they are at least a double D cup if not bigger... She also has a perfect round ass.

The issue started one day when my girlfriends youngest sister, I'll call her Sarah for the story. My girlfriend had gone to bed early because she wasn't feeling well. After watching some TV in the living room, which is where Sarah sleeps when she stays, she said she was going to change into her pajamas. I though nothing of it because this was always her routine.

What I didn't know, was that my girlfriend usually had to make her wear "decent" clothing to bed every time she stayed. Since my girlfriend was not awake, nobody said anything to Sarah about decent clothing. She came out of my bathroom about 10 minutes later wearing a very short shirt. Almost so short that I could see the bottom of her tits. She also wasn't wearing a bra. Her pajama bottoms were just a pair of short shorts.

I couldn't help but stare. I knew she was too young but it still made me rock hard. When she went to sit back on the couch, she put her feet in my lap. Sarah was always very flirtatious. Even when her sister was around she flirted with every guy she was near. I know for a fact that she felt my solid dick under her feet. I swear she even rubbed her feet back and forth on it.

At this point I was so horny that I wanted to just rip that shirt off and watch her tits bounce while I pounded her, but I need to stay in control. I tried to not look her way but as she tossed and turned the shirt slowly slid higher and higher. Eventually her tits were just hanging out. Now I'm not a girl so I can't say I know this, but I'm pretty sure Sarah would have noticed that her tits were out. I got even harder. I stared and stared and stared at her perfect round perky tits.

After a few minutes she sat up on the couch, complaining of neck pain because of the way she was laying. She said nothing else but proceeded to lay her head down in my lap just inches from my now throbbing cock. I wanted so badly to fuck her that night, but I still know that it is wrong for me to act that way to a girl as young as her. As she "moved to get comfortable" as she put it, she ended up with her mouth basically touching my dick through my shorts. It was obvious that I was hard right in her face.

All at once, she pulled the leg of my shorts up and sucked my cock into the back of her throat. She gave me the best blow job I have ever had. She was perfect with her sucking and stroking all at once. Within a few short minutes I was already filling her mouth up with my cum. She licked every last drop up. After she was done she just laid back down the other direction and went to sleep... I have been fantasizing about fucking this girl every second of every day since then. I want to know the feeling of that 14 year old pussy wrapped around my dick more than anything else in the world. I don't know what to do...
