Some time later in his bed. As for the how...

James felt warm and cozy. As his mind slowly booted up, he felt how sore his body felt; legs and abs in particular ached as if he'd run a marathon and then did a hundred crunches to round the day off. He was lying in his bed on his back, covered by his blanket, one arm on his stomach, the other next to his pillow, pointing to the headboard. Judging by how he felt the linen of his bedding on the skin of his arms, legs and most of his torso, he was wearing... not very much. James could feel his now so much bigger cock limply lying on his stomach, held by the rubber waistband of... bathing shorts? Opening his eyes, James blinked the sleep from them and sat up, only to find himself face to face with his huge-breasted mother gazing at him lovingly, sitting next to him on the bed.

"Gah! You scared me, mom!"

"Awww, sorry, sweetie, I like, totally didn't mean to!" Anne replied with worry, eyes wide and hands clasped over her voluminous tits, "I just totally couldn't resist watching my baby sleep!"

Her puppy dog eyes and quivering lower lip took the wind out of James' sails, and he answered sheepishly: "It's alright, I was... I was just surprised is all. What happened, anyways?"

"Uhm, you, like, totally fainted, and me and Micaela knew you had cum sooo much that you had to be totally exhausted, so we wanted to carry you into your bed. But then we, like, noticed you were soaked in yummy cum, and Micaela stopped me from licking it off you, so we had to use the sponge in the bath to get you clean, but you, like, didn't get hard at all and then we put some of my running gear on you so you weren't totally naked, and then we put you to bet, and Micaela cleaned the kitchen before she, like, left, and I watched you sleep. And, uhm, that's it."

James blinked a few times, trying to process the run-on sentence Anne had just rattled off seemingly without breathing. He used that time to take in her new body - she was wearing her usual jeans she always wore at home, but her oversized tits were much too big for any of her tops, so she apparently had elected to fashion a makeshift tube-top out of one of the white linen bed-sheets the whole family used. It left much of her cleavage exposed and despite covering about three quarters of her enormous bosom, the amount of flesh not covered was still bigger than James' whole bust. A pang of jealousy shot through him, but he quickly suppressed the feeling.

"Wow, uh, thanks, I guess," he replied weakly, throwing his blanket off his naked legs. Giving himself a once-over, he saw that the running gear his mother had mentioned was a pair of baby blue areno™ shorts - so short they were actually more like hot-pants - with dark blue stripes, and a matching top that ended right under his hand-filling bosom, leaving his flat, toned tummy exposed. The ensemble was skin-tight, his prominent nipples clearly visible through the fabric. As was his cock, except for the foreskin-covered helmet poking out of the waistband.

"It was, like, a total pleasure," his mother answered, and James looked back at her just in time to catch her looking away from his crotch with a mix of hunger and longing in her eyes.

"Did... did Micaela say something before she left?" James asked, a little scared of the answer. Sure, she had said she was his girlfriend, but she'd also left without saying bye...

"Yeah, sure! Uhm, she said, like: Tell James I'm totally sorry, but I, like, got another client and here's my number and, you know, you should totally call her!"

With that, she thrust a piece of paper towards James with a string of numbers on it. James was elated; this was the first time he'd ever gotten a girl's phone number!
