I read it since i was a virgin but this is my first time I am writing one.Since a long time getting sex has not been a problem for me.I and my girlfri...nd share a wonderful sex life.I am very faithful to her.But the incidence which I am going to tell you, made me betray my girlfriend.This was the first and last time i betrayed her.My experience goes like this.I do my studies away from home in Mumbai and here I have a great pal Kushal who lives with his sister. During exam times we both used to. Now I want each female to put on a pair of gloves. Now each of you know the normal ways of extracting semen from a male though masturbation. This exercise is to instruct how to get the same sample though prostate massage. Now please no giggling, laughing, or rude comments. And women remember we have pap smears and pelvic exams coming up and each of you will be participating in that.The females will need to figure out between yourselves who will be doing the internal work and who will be doing. He's got a pretty big dick!" That comment & the attraction I felt started arousing me. I get closer to him & I catch him stealing glances of me. Our eyes meet a few times & he begins looking at me more intently. We were both talking to other people but it seemed now we were having this unspoken conversation going on between us. He then leans over & asks my bestie's man something. I see them look over in my direction & after a few more comments I see him nod towards the house. I wasn't sure what. He is helping by holdingthe back of my head and giving me as much as I can stuff into my mouth and Itake it all!After I make sure his cock is wet, I scurry up on the bed and turn my asstoward him, he gets the not so subtle message and turns me to his advantage,on my side with legs spread open. He takes no time in thrusting his cockinto me; no nicety just pure fucking. I egg him on by telling him that myass is his and to take all of it. He is very good at what he was doing andtook his time.
