Sharon nodded trying her best to keep up with the lie Xavier had been saying to Jason. "It's ok whatever let's just move on from it.." Sharon smiled at the suggestions of watching some movies and watched Jason disappear upstairs to make popcorn. Turning her attention to her new teen lover she was a bit surprised at his suggestion of ruining the only other available seat. She did as she was told and picked up a half drunken can of Pepsi near where Jason had been sitting and poured it into the couch cushion. Sharon then climbed into Xavier's lap facing away from him. Her big as pillows out over his lap and she could feel his big cock underneath. The blonde mom began to grind and rub herself against his crotch. Her thin shorts left little between them and it was running against her making her horny again. Sharon leaned back into him and continued to grind and give her son's friend a lapdance. Sharon turned her head and kissed Xavier letting him have full access to her whole body. She was horny for his cock again and thus was going to be difficult over the next few hours. Sharon then got an idea.<br/><br/>The lap ance was short-lived due to how eager Jason was to come back down and join them. The heavy sounds of his feet thudded down the stairs and Sharon straightened up. She could see the confused look on his face and Sharon immediately went into an explanation. "I'm sorry honey clumsy me I dropped a soda can I was passing to Xavier and it spilled all over the cushion. I thought it would be weird if I sat on your lap and you wouldn't make your mom sit on a wet seat or on the floor?" Sharon flashed a warm smile trying to make the situation she was in seem as less sexual as possible. It didn't help that she was sitting on a very big bulge and her shorts had grown even more tight making the outline of her plump mature pussy very visible. She was dying to ride his big cock now but it would take some time. Sharon needed to stop and pace herself.<br/><br/>Sharon climbed off of Xavier's lap "let me pick something for us to watch okay!" She heard a groan from her son but She ignored it and pranced over to the shelf of DVD's. Her big ass had swallowed up more of her shorts from riding and grinding on Xavier's lap. Her shorts looked more like a thong now with 3/4 of her was cheeks hanging out. They jiggled and grew wider when she bent over to look at the bottom shelf. She was half giving them a little show. With her bent over the shorts couldn' contain all of her pussy and her big mature puffy pussy lips peeked out of the sides of the thin strip of shorts material going between her legs. She pulled out a big DVD box and read out the title "Game of Thrones" she looked to the two boys for approval. "I don't think I've watched this before. You know it could be even more fun if we maybe play a drinking game while we watch it?" Sharon grinned at the two boys wanting to seem like one of the cool mom's that let her son party a bit. "Set it up honey.. your good at stuff like that!" She asked Jason. Sharon disappeared upstairs and then returned with a bottle of tequila and shot glasses. Her tits looked ready to pop out of her too small top as she moved around setting up the shot glasses. Sharon mostly stood in front of Xavier letting him have a perfect view of her big ass. When everything was all set Sharon sat back down in Xavier's lap. Wriggling her ass a bit she could feel the bulge pushing back into her big ass.
