How I got my 20 year old girlfriend's 12 year old little sister to suck my cock.

I'm 33m, my girlfriend is 20. This happened right when we had just started dating.

My girlfriend had been out to dinner with her girl friends and I was at my place. One of the friends had turned 20 so they had gone to a fairly nice restaurant and had quite a bit to drink. I was her designated driver for the night. She called me at around 12 and I drove her home. She was still staying with her parents but they weren’t home, her 12 year old little was tho.

My girlfriend was pretty drunk and had gotten pretty handsy in the car. She gets to be pretty fun when she is drunk. When we got into her parents home she started unbuckling my pants, I didn’t complain but I asked “What about your sister?” my girlfriend said “Oh she wont notice”. Man was she wrong, haha.

We got into my girlfriend’s room and I started fucking her from behind. Like I said she was pretty drunk which meant she was pretty vocal. She was moaning loudly and talking dirty. “Fuck me like a filthy whore” etc. After a while I caught something in the corner of my eye. I looked to the side and standing in the doorway was my girlfriend’s 12 year old sister. My girlfriend didn’t notice and I didn’t stop fucking her. The 12 year old looked enthralled with what she was seeing. She was only wearing panties and a thin white top. You could clearly see that her little nipples were hard. I kept fucking my girlfriend while making eye contact with the 12 year old. She was a bit shy but didn’t she didn’t look away, her eyes wandered between me and my girlfriend’s body being pounded from behind.

After some time my girlfriend came and she more or less passed out naked on top of the bed. She had no idea that her little sister had just watched her being pounded from behind like a whore. I turned around to walk to the kitchen to get a glass of water. As I walked through the doorway, passing the 12 year old, I looked at her but her eyes were LOCKED on my cock that was still hard. Granted I’m 6’2 and she is like 4’8. I walked into the kitchen as she lingered behind in the doorway.

I was standing by the sink drinking a glass of water as the 12 year old sheepishly sneaked into the kitchen. I turned around and her eyes were glued to my cock. You could tell that she wanted to do something with it but that she wasn’t sure what. I motioned her over and without hesitation she walked up to me. She was standing a few inches from me, I could hear how heavy her breathing was. I put my hands on her chest and felt her heart almost beat out of her body. I gently caressed her small titties and whispered “Get on your knees”. I think she was confused but she did it without hesitation.

I whispered again “Open your mouth” and she did. I could probably had said anything at that moment and she would have done it, it was like I had a magical spell on her. I took my cock and slowly guided it to her mouth. Trust me when I tell you that you need to experience a 12 year olds lips around your cock. It felt amazing. When I put it in she gave this audible sound that as if she was tasting the best thing she has ever had in her mouth. The best part? I hadn’t washed between fucking my girlfriend and the 12 year old sucking my cock. So she was tasting her older sister pussy. Slowly and gently she started to move her head back and forth while breathing these pleasure sounds through her nose. I loved it and she loved it and she was a natural at it.

After what felt like 30 minutes (probably just 3 minutes) I felt my self cumming. Mind you, I didn’t cum while fucking her sister. I took it out of her mouth and came on her face. It was a pretty big load too. I was sort of expecting her to flinch or pull back but somehow that seemed to turn her on even more. I picked her up and carried her to the bathroom. I gently washed her face as she caressed my body. I then carried her to her bedroom, tucked her in and kissed her on the forehead. Went down to my girlfriend’s room to sleep. She was still knocked out and she had no idea that her 12 year old little sister had just given her first blowjob.

The next day at the breakfast table was pretty funny. Her parents had gotten back in the morning so the whole family was there. Mom, dad, my girlfriend and her little sister. We were talking like it was any other day but none of them knew that just a couple of hours ago, a few feet from where we were sitting, the precious 12 year old little angel had just suck her first cock to completion.
