My girlfriend is 20 and she has a sister who has just turned 16...I love my girlfriend but fantasize a great deal about seeing her sisters tits. Her sister always tells me to wake her up for school before i leave for work, I have done this for about 10 weeks and in that 10 weeks i have seen a lot of glimpses of her tits but yesterday she was on the top bunk..*she used to share bedroom with her brother now he has his own room but she still has the same bed* When she rolled over her tit was just there!!! so i just stood there got my cock out and wanked while chatting to her as she was half asleep and cum on the bottom bunk as i carried on looking at her and chatting...yes im bad but tell me you wouldnt have!!!! anyone else had similar experiences
