It wasn't easy to break away from having sex pretty much every day but I got scared something might happen and I would be doomed to having a k** and a...wife and all that before I really had a chance to have fun. So here I was floating in the pool, listening to the radio and drinking margaritas that Mom made. It really wasn't that bad.I guess I was zoned out in my own world pretty deep because when Mom called my name I didn't hear her at first. "Bobby!... Have you gone deaf?". I snapped back to. He held her head tight rendering her unable to move back. She speeded up her wanking and soon he screamed out "OH YES, TAKE IT MRS YATES, TAKE MY CREAM!" The first spurt went straight down her throat and his hands relaxed their hold allowing her room to accommodate the remaining copious amount of spunk his tool disgorged. She savoured each ejaculation before swallowing. When his climax had finished, she released her suctioning grip on him and moved away. "Bloody Hell Mrs Yates, that sure beats. I undressed and lay back on the bed so Uncle Robby could climb on top of me. He sunk himself into my cunt and rocked his hips thrusting himself in and out of me. I spread my legs wide and rocked against him feeling him penetrate me so deeply. I loved the way my retarded uncle’s cock felt inside my cunt. His belly slapped against me as he continued to fuck me.“Oh yea,” he moaned and his body shivered. My Uncle Robby was cumming releasing his load into my womb. I pulsed around his throbbing. Tally just stuck her nose in a magazine and pretended not to notice their attention. Everybody seemed to notice, but none of them was rude.Barb's plane arrived and she gave Tally a big hug even before she greeted me. She didn't have any checked luggage so we went straight to the car. They chattered all the way home. Neither of them asked me anything or said anything to me at all. I didn't mind. I was thinking about what we'd do when we got home. My cock was at varying degrees of erection all.
