Mark had stepped out of the shower and dried himself off as he waited quietly for his mother to return. From the looks of his father, he most likely was still passed out on the couch and hopefully his mother would return to the bathroom and they could continue what she had started the night before at the Christmas Party. Remembering how good she made his cock feel as she sucked it like he had never had it sucked before, he felt his cock begin to throb. Yeah, he had received blow jobs from two of his girlfriends, but they really were no where near as good as his mom was and besides, they either moved their mouths when he came or else spit out his cum into the sink. It was so incredible to see him mom, swallow every drop of his sperm and then kiss him hard on the lips.
Listening for his mother to return, he licked his lips, tasting a bit of his mother's juices still on his mouth. Savoring her taste, her reached down and gently began stroking his cock, wanting to be ready for her when she returned. Looking over the bathroom, he wasn't sure what they could do in the cramped space, maybe they could move out into the bedroom. He was still pondering the possibilities when she opened the bathroom door and then locked it behind her.
Without hesitating, she walked over to him and drew him to her, kissing him on the lips, pushing her tongue between his lips and into his mouth. Reaching down, she grabbed his cock and rubbed it up between her pussy lips, getting the head of it wet as it slipped over the opening to her cunt.
