I normally spend every weekend at my girlfriend's house. She roommates with her sister who is younger than her. My girlfriend works odd shifts and sometimes she has to work on the weekends. I normally try to stay anyway because we can at least sleep with each other even if we don't see each other during the day. Normally when this happens I will spend the day with her little sister instead. She just turned 20 and still doesn't know what she wants to do in life. This past weekend was another one of those weekends where my girlfriend had to work, only they changed it up and told her she had to work 2nd or 3rd shift. She chose 3rd shift and waited until 10:00pm to leave for work. Her sister and I told her good bye and then sat down to watch TV. Around midnight I decided I was tired and told her sister good night. I don't know what time it was but some point in the night I was awoken by someone pulling my shorts down and then sucking on my d***. I was only half with it and somehow thought it must be my girlfriend. So I went with it, letting her do what she wanted. Then she crawled up on top of me and slid her p**** down over my d***. By this time I more awake and reached back to grab her ass as we f*****. It was then that I realized it was my girlfriends sister who was f****** me. I wanted to stop her, but it felt so good and I was so h**** and besides that I was already up inside her. I decided to say nothing and we continued to f*** with her having several O's and then me c****** in her p****. After we finished I reached over and turned the light on. Sure enough there sat her sister on top of me with my d*** still up inside her. She told me not to tell as she got off me and started to put her clothes back on. I agreed that we should never tell but now she keeps saying things to me when my girlfriend is not around about how good s** was and that we should do it again. I will admit she does have a great p**** even if she does have small t***. Now I can't stop thinking about her and I'm scared that the next time my girlfriend has to work weekends her sister and I will be f****** again.

  • Just close your eyes and pretend its your GF only.

  • Only problem is that my girlfriend is bigger than her sister. Don't get me wrong, my girlfriend is by no means fat at 140 pounds, but she does have more curves, bigger ass, and bigger t***. Her sister on the other hand, weighs maybe 100 pounds, has no curves, no ass, and no t***. So I can imagine all I want, but as soon as I grab her ass or t***, I'll know.

  • You got tna and a spinner. Spinners are greay fuc ks and are very flexable.

  • I get that you are much more into your girlfriend but I was trying to highlight the buy 1 get 1 free option. Me too like chubby babes but sometimes light weight with smal t*** really horney which turns me on,ending up with great sexx
