She lapped up Joe's heavily veined cock-stalk, then pulled back again."Lie down," she whispered. "I wanna sit on your cock now, Joe! Let me ride the f...cker!" That was fine with Joe. He sank to his knees, then dropped over onto his back, arching so that his prick was towering above his loins, jutting straight up like a stake, as if he had been impaled on his own pole.Tracy squirmed up, onto one elbow, eager to watch Jennifer screw her brother. She was wondering whether incest was more naughty. "Thank you.....my sweet little slut" I can feel it shrinking inside me, it's job done.My reward, a belly full of old man cum.He slowly withdraws the glistening member with a schlock noise, a wet noise.He moves back away allowing me off the toilet seat. Getting off I feel just how wet I am. Quickly grabbing some toilet roll and begining the cleaning process. My panties are wet where it's dripped down, being careful not to get any on my skirt i dry my thighs and wipe a pool of it off the toilet. "That's good for now. Now it's your turn to prove you're worth my time." she said. I looked down, confused when I saw a ring around the base of my cock. "To keep you from cumming." she said "I could tell you were about to and you haven't earned that yet."She got up, standing nice and tall and spread her legs. "Time to lick me bitch boy. You wanna get to cum don't you?" Eager to please I got down and began licking her. After a minute or so she was really getting into it. She grabbed the back of. As I walked up to it I noticed that I was alone, so I slipped my towel over a chair and dived in. The water temperature was just right and after a few lengths I started looking up at the rooms facing the pool. My mind started to wander, wondering if anyone was watching me.The water seemed to caress my cock and balls beneath my shorts and I started to throw a boner. As my erection increased I started swimming breast stroke, the length of the pool and the resistance of the water against my now.
