Bedtime

As Peg drops you off she says. "Now, you might find you are extra horny and more aggressive for a while. It will take some time to adjust. I suggest masturbating a couple times a day just to stay loose."

You reach over and take her hand. "I can't thank you enough Aunt Peg."

She just smiles a 'you're welcome.' Then she adds. "You might notice some other effects going forward. You shouldn't get sick as often, you should recover from injury a bit faster, you'll just find you are sharper and healthier overall."

You blink, this was getting better and better! "So...I'm like some sort of superman?"

She laughs. "No no no. I just tweaked some dials, you are still very much human. Don't lose your head now." Then she says. "That said, due to some of my tweaks you are primed to respond to exercise faster than usual. If you ever want to start working out you are free to come over and use my gym." She gives you that smoldering milf with glasses look once more. Working out suddenly seemed like a really really good idea.

"I'll think about it." You respond. She gives you a few more bits of warning and advice then tells you that she'll want to get you back to the lab soon for some follow up tests. You listen and agree wholeheartedly, you owed this mad wonderful genius of a woman so much.

You thank her once more then give her a hug and exit the car. You sneak into the house and up to your room. You strip down to your underwear, you couldn't wait to get to masturbating! You were randy as fuck. You head out of your room to go brush your teeth and notice the bathroom is occupied. A moment later your mother opens the door, bleary eyed and half asleep. You can see her from the dim nightlight in the bathroom. She is wearing a sheer powder blue negligee with matching panties, her thick voluptuous body fills thin fabric to the limit in every possible way, you feel your manhood swell an inch in your constricted shorts from the sight of it. Her big fat nipples were easily visible through the cloth even in this dim light, she had a bulge in her undies that matched your own.

She pauses at the door, she hadn't been expecting to see you. "Oh...hi baby boy...what are you doing up?" She asks, her eyes half closed. "Everything okay?" Her voice had a sleepy monotone quality to it.

You didn't really want to tell her that you just got in so you instead you say, "I...uh...couldn't sleep."

"And you wanted to crawl in with Mommy?" She mumbles in her tired voice.

That wasn't what you were thinking at all, you hadn't done that since you were little, but who were you to argue? By her mostly closed unfocused eyes it looked like she wasn't really awake, she probably wasn't thinking straight.

You seize the moment. "Yeah...would that be okay? Can I sleep in your bed?"

She lightly pats your cheek. "Of course sweetie." She shuffles off toward her room, you admire her big shapely double wide ass as she goes. "Come sleep with Mommy baby boy."

You follow right in behind her, masturbating would have to wait.
