Maybe rub one out before he leaves, just to be safe. But to who?

John gently closed Megan's door, then turned to start heading out the front door, but something's off. He felt it deep within his loins. Megan's huge soft body had gotten to him. That little kiss had sent shivers all over him, and now he wanted more. He couldn't. He had to focus, but he couldn't. He decided, as his pants became increasingly constrictive, that he need to just rub one out. John quickly went over to Megan's bathroom, dropped and his pants. His eye went wide. His dick was bigger. Not, like, monstrously huge, but bigger. It had to be connected.

He slowly reached down a hand and start stroking it. It felt so good. His mind immediately went to Megan. No, can't be her, can't do it to her again. His mind wandered, he tried to just focus on the idea of something sexy, but that's not how his brain worked. Suddenly, his brain snaps to Ms. DeRosa, his English teacher. What if she took his growing meat into those thick lips of hers? And then his cum would make her grow. He moaned, quietly. He leaned over into Megan's shower and unloaded. One, Two, Three, Four, Five huge pumps and it was over, milking it further elicited a further three pumps of thick cum onto the floor of it. John caught his breath.

What would happen to her? Well, he figured he'll find out in a couple days at least as he cleaned up and put his pants back on. They were still uncomfortable.

Driving to the nearest store was easy, only a few minutes away. Walking in, heading to the plus size section, easy. John picked out a nice color. Black. 'goes with everything' he thought as he clutched a pair of leggings in one hand. Thinking of Megan wearing just this; it was getting him horny again.

Again.

He tried to push it out of his head. He was walking past the bathrooms when he saw a wide hipped blonde woman, she was wearing a shirt with the name of his school on it. Does she look familiar? He couldn't tell. Her hips looked amazing. He wanted to-- He stopped himself and ducked into the bathroom. In a stall, he whipped it back out and start working it. It feels heavier. His mind raced with thoughts of the woman's hips growing fatter and bursting from her leggings, boobs bursting from her bra, belly pushing out from under the tight shirt. John was going to try and fit it to point into the bowl, but it wasn't going to fit. Thankfully, it shoots over his pants around his ankles. So much. Too much? He cleaned up and got situated again. Had to get back to Megan.

John watched the floor as he head to the self-checkout. He quickly made it, paid for the oversized clothes, and started to head out.
