I quickly made my way over to the other side, slid under the sheets and turned on my side facing away from him. "Goodnight Rob" I said. "Umm sis? Are ...ou ok?" Without turning I replied " yea, of course, just tired" " you have been really quiet all day. Are you sure you alright?" Asked Rob. If you only knew what your perverted sister did. I thought to myself. Shaking that thought away I replied faking a yawn " really im fine Robby, now shut up and let me sleep" I heard him chuckle " alright. I was watching this too my hand still forcing you forward against the door and your hand still wanking my cock which had pre cum dripping from the tip. The guy that came in you stayed inside as long as he could but then he slipped out and a gush of cum followed his cock from your gaping pussy on to the floor. I looked behind you to see his wet cock move away and see the pool of cum on the floor, and I felt you jump and moan so when I looked back I was quite surprised to see the guy in the room. Peter was approaching seventy, but the advent of Viagra had rendered him a horny b**st indeed. We would have sex of some form every morning and every night almost without fail. He had been turned into something of a randy old goat. Not that I was complaining you understand!Christmas brought the inevitable round of socializing and parties- some fun, some tedious. One of the main ones was a fancy dress party at an old friend of Peter's- a one time lover of his in fact. Not my absolute favourite. “I am not done with you yet” Coach H tells me after he pulls his still hard cock out of my ass. He flips me on to my stomach and quickly slides his cock back into my ass. Coach H starts thrusting with power and speed again. Good thing his cum was still in my ass to provide lubrication. After several minutes of having me lean over his desk while he thrusts his cock in my ass Coach H pulls me to the ground and has me on all fours. At first both of his knees are on the floor then his right.
