My girlfriend of 4 years has been pegging me for...well, for four years. We met at the university where I am still a student, as she was when we met. She has now just become a staff member and was recently divorced when we met. She is about 10 years older than me and I was a virgin when we met.
She took charge right from the first time we met, arranging a meeting at her place where I slowly undressed for her and then pleasured myself - very slowly - at her instruction.
Four months later( after incredible, unbelievable, relatively straightforward sex), without going in to all the details, I found myself tied up, naked, on my knees at the foot of her bed looking into the eyes of my girlfriend's best friend, my girlfriend out of sight behind me.
I did not expect what happened next, since I had no idea that women would ever do anything to a man's ass. Of course, my girlfriend had fantasized about penetrating a man for a long time and she penetrated me without warning, using a 6 inch hand held dildo, proceeding to do me at top speed for the next few minutes.
This experience changed me forever; I now am penetrated regularly, at least twice a week, by the two women. Needless to say, the 6 inch dildo is not used very often and large strap-ons are kept in the night tables.
Both women are extremely happy with their sex lives and have repeatedly complimented me by saying that I am very skilled - the best they have ever had! - in the most important aspect of sex, namely performing oral sex on them. They also are full of compliments about how much they enjoy riding me, on the rare times that we the 'usual way' - I am always on my back, of course, and I am not allowed to climax inside them.
I am also extremely happy to be their bend over boyfriend. I can't really think what life would be like without bending over.
