He too was pleased with our submission to him and was going to enjoy our efforts to please him. He had his cock all the way in her ass and she was whi...mpering into the mattress. He told me get on the bed and lay my head on her ass and watch his cock thrust into her ass. I did as I was told. Every few strokes he would pull his cock out and stick it in my mouth. "Taste that ass? Taste good?"..."Mmm hmmm" I would say with his cock in my mouth. "You like that big black cock in your ass, bitch?" All. I figured she would of just closed the door to give me privacy but instead she stood there - I still remember it - she had just gotten back from a morning jog - she was wearing running shorts, a white tshirt and was glistening in sweat (she was an attractive woman) - needless to say for a horny 17 year old virgin it wasn't the worst thing to see in the world lol.So I just stood there dumbfounded, totally like a deer in headlights. I can't really remember how long she was there for - 30 seconds,. After a couple of compliments and kisses I'm already ready.I crouched towards him and pushed him around his stomach feet, arranging for a better penetration. He was very rigid, pressed on my entrance, instinctively opaque.Not much waited and was already in, slowly and thin, almost whole.Do I love you, I get something in my ear, and the feeling is getting enormous to me. Let's take the moves to enjoy it better, without paying attention to anyone. With the statement that I'm very sexy I feel it. This made me want to grope him, rip the shorts and stuff his penis in my mouth, which was a very weird feeling to have, I'd never had such a thought up until this point. In this dazed and confused state I forgot the right rhythm of exercise and pulled a muscle. It was really bad and I had to make a huge effort not to yell some obscenities. My trainer came to my rescue and took me to the massage room to take a look at my injury. He began to massage my leg and I guess what began as a massage to.
