Beth Fooling Around

She knew exactly what she was doing. The second after Jason had entered that command, it felt like a veil had been lifted from her eyes. Jason was aroused by her sight. Obvious at his age, she had just been blind to it, or rather intentionally ignoring it. But now she not only no longer did that, but also... she was enjoying it. She had been hesitating all her life, and now - in just a click of a button - she was running through her past self and had just one question on her mind: why? Why did she let go of all those chances on having fun, on screwing around, on enjoying life? Today was the day where she would stop to be prude, and just flow with it. Speaking of: she very much enjoyed how Jason was struggling to contain himself. She felt the warmth spreading in his groin, and just knew how he was fighting for his life to not grow a boner under her soft ass pillows. She was so going to tease him with this, till he breaks, and then probably some more.

"Mind if I try a change on you? I think I got now how this works." she asked casually. While Jason grunted a no, she had already opened up his profile. "Wow... it says you are aroused right now, any idea why?" she played dumb. Jason refused to answer. "Anyways... let's see your stats... interesting... it has all of it here, like... literally all of it." She gave Jason a moment to process that she was looking at all his sexual stats, but eventually he got a grip on himself and peeked past her shoulder and saw her staring at the sliders for his dick.
"Please be careful mom." Jason was panting heavily.
"Of course I am, honey." she chirped. And she would, it was her son after all. "4 inches isn't that big, is it?" she derailed the subject.
"Mom!" Jason protested, but a little wiggle of her ass broke his concentration almost instantly.
"Just reading what's there dear..." she started playing with the sliders "I mean we can just change that, right? Isn't it after all what you boys are all looking for? A bigger dick?"
"Mom... please!" Jason's protests became louder, but she was on a mission. A mission that started the moment she read that her son was still a virgin, and that was unacceptable after her recent revelation. She moved the slider to 8 inches, which would be more than enough for him to satisfy any girl. But then a strange idea hit her, that came right out of her very recently gained skills. She had been too scared to show what she got, too scared to let anyone see her. And as she looked down at her now massive tits she realized that the cure was easy: just be too big to hide. So she ramped up that slider to 14 inches and sent it.

"Mom?! Mom, what did you do??" She heard Jason panic from behind while suddenly something was expanding in his pants fast. "Mom, what the fuck??" he gasped, and Beth could feel his member starting to harden under her ass. Being teased like this and having his dick grown huge was too much for him, as intended.
"Sorry hun, I am just trying things. Is this too big?" she played dumb. Jason however didn't answer as he went into a series of grunts and pants. But then much to her surprise the growth in his lap stopped, and that semi slowly went back down. Briefly she admired the self-control her son had, but then this was neither what she had planned, nor was it acceptable for her new role as sexual teacher.
"Sorry, I fix that, promise!" she lied, and went right for the black box, while she distracted him by squeezing his oversized member some more.

[Jason can and will get hard easily, and can stay hard indefinitely without any medical issues. He has no control over his erections.]

"Mom... what..." were the last words she heard before a lot of blood went down into his groin and shut down his thinking for a while. His control over his erection had been admirable, but it ultimately would just make him miss out of the fun. She knew how much she had fantasized about a boy who grew a boner just from looking at her when she had been his age. Literally the most honest compliment a woman could get, she understood that now. Sure, it was embarrassing at times, but it certainly would help him to get laid. The trick is to show what you got, she had learned just a few minutes ago herself. And under the careful rubbing of her cheeks, her plan unfolded. Quite literally...
"Oh my!" she pretended to be surprised after she had gotten up and turned around. She had minimized the program, so Jason wouldn't immediately see this was all her doing. And what she saw in front of her was definitely very entertaining.
"How big did you make me?!" Jason said with audible panic in his eyes as he tried his best to hide a cock that bulged not only his pants but also his shirt dramatically.
"I thought this was 7 inches, but probably I got the scale wrong?" she felt herself getting aroused by the sight of so much dick. "We should get it out, I don't want you to get hurt."
"NO!!" Jason protested, but before he could react she had already swiftly opened his pants. And into their view a gigantic tower of a cock emerged. A throbbing shaft reaching up to his chest, with a head so big Beth wasn't sure if she could even give that a proper blow-job, but she certainly would be willing to find out..
"What got you so aroused?" she tried to sound as innocent as she could. His eyes briefly went to her massive rack, and his dick immediately twitched and got even harder. He literally had zero control over his erections now. "I see..." she let him know that she knew, and Jason's face turned even more red. "Now what are we going to do abut this?" She definitely had a few ideas, but then she wanted to give him some saying in this also.
