I would watch gran all the time,her ass would drive me wild with desire,when she would bend over in front of me,I would imagine what it would be like ...o touch her ass,and feel her firm tit’s,the normal thought’s of any 15 year old. One night while Grandad was out drinking,I was lying in my bed when I heard a noise that made my ear’s prick up, it sounded like it was coming from Gran’s room,I sneaked down the hall and stopped outside Gran’s door,I could hear moaning coming from inside,her door. Just to complete the look was a pair of pink sweatbandsand matching headband which I thought I'd better put on. With that I crossed the hallway into the new gym. It was impressivelykitted out with lots of mirrors, machines and large TVs. "My, don't you look cute," said catherine slapping my hard on my exposedass cheek. "It's time to get you in shape young lady. The exerciseroutine is written on the wall over there. You'd better follow itexactly or there will be consequences." With that she. 1st her sari, next her blouse, now petticoat, oooh no, now she is in bra n panty only. She came top of me n started kissing me all my face, ears, eyes, cheeks n now hmm lip lock, her lips r so soft n tasty, we did lip kiss so long n played with tongue like French kiss.Later she moved down by kissing n started removing my short and there it is the gateway to the heaven, now my penis rose with 90 degrees n saluting her figure n body. She now put kisses to my penis n started sucking my penis my. That's what I thought this was."Without another word, she put her mouth over my dick and started pushing up and down on me, rubbing my balls and legs with her free hands. She went up and down at an increasing speed, deep throating and almost gagging on my cock at all the appropriate times. Having this girl who had been, just a couple hours ago, more or less a stranger to me suddenly going down on me was a huge turn on.I ran my hand along her back as she orally pleased me, making sounds of.
