Preminilary Testing

Kelly had Jack lay back on the bed as she examined his new body. His muscles really felt more defined than before and for a while Kelly was just lost in the moment as she slowly caressed his arms and chest. "Wow... Can you try to flex for me?" Kelly bit her lip in anticipation as Jack slowly curled his arm. She had to grab his bicep and feel it in her hands. "...Does it hurt anywhere? Do you feel different?" Jack simply shook his head. For a moment Kelly wondered why he was so quiet before realizing that she was basically straddling his lap and had her tits out in his face. Which reminded her again of another part of him that she needed to inspect... She had been delaying this because it worried her but there was no way to ignore the issue so slowly she worker her way down his chest until she was between his legs and had his cock right infront of her.

Jack was at least as big as she was. Jack winced a bit when his mother finally reached out towards him again. "Can I... Can I..." She didn't even realize that she licked her lips before continuing, but Jack did notice it and his dick twitched immediately in response. Jack nodded slowly. Unsure of how far they would go. The strangeness of what happened to his mother first and then their accidental(?) incestous encounter the night before were already insane. But now he didn't know if he wanted to stop. As for Kelly, than anything else, she felt proud. "You sure grew up fast..." She stroked him slowly. She hadn't even noticed how big his testicles had grown but as she cupped them in her hand, they felt heavy and so full. "Mom..." For a moment Kelly worried that Jack would ask him to stop. "Do... Do you think I'm too big now? What will girls think?" His mother grinned at him. "Jack, my son... This monster will absolutely destroy any girl you try it on. ...But they'll love it." She stroked him faster and brought her face closer to the cock. "Trust me... You'll find a girl who can take this and when you do, she is a keeper." She hadn't actually made the decision to suck him off, but she suddenly realized she was doing so anyway. And Jack did nothing to stop her. His precum tasted delicious and Kelly found herself moaning and trying to fit him as deep as she could. Jack for his part grabbed her hair and pulled her deeper until she gagged on his cock. "Oh shit! Sorry mom, I didn't mean to!" He let go and Kelly gasped for breath before reassuring him. "Relax. You're just a bit on the edge, we better see if you can cum. ...Just to make sure everything is working." Jack's cock was slick with saliva and precum as his mother leaned down again and bobbed her head up and down on it. Kelly could feel her pussy tensing and she wondered just how good this cock would feel inside her. If Jack was willing to go that far that is... But for now, she only cared about sucking his cock and it was turning her on so much she felt like she could cum from just this sensation.

Eventually Kelly felt her son tense up. "Mom! I'm gonna!" YES. Kelly doubled her efforts and soon felt him cumming. At first she was swallowing it all, but there was just too much. She had to come up for air but tried to keep the bed clean. She cupped her breasts and opened her mouth wide. "Cum on mommy's face!" Jack sprayed more and more of his cum on her face and down onto her tits. When he was done, his mother's face, hair and chest were covered in his cum. He didn't think he'd cum this much in a month, much less at one time. "Mmm... I'd say you are a healthy young man and there's nothing wrong with you... Help me get to shower before we make a mess of the house." Kelly was still horny as hell and hoped that Jack wouldn't mind returning the favour in the shower. With the look on his face as he stared at his cum showered mother, she felt pretty confident in that at least. And even if he would eventuall find a nice girl and settle down with her, Kelly had no intention of giving up on him completely.
