Meanwhile, your mum arrives at the yoga studio, her mind a bit clouded by the rising lust as her new cock continues to rub against the fabric of her yoga pants. Thankfully, she arrived a little bit late and the class was already starting with some stretches.
Embarrassed by her tardiness, she quickly put her bag down and set out her mat before following along with the rest of the class. That's when she realized that even the warm up stretches were giving her hard time. As the stretches continued, she noticed that the room felt a bit stuffy, but shrugged it off as her own workouy smell, even though it would normally apply to a gym, not yoga.
What she didn't notice was that the smell was actually filling the entire room and the others began to notice as well nor that it was because of her cock and the leaking cans of Hogbrew she brought in here bag. As the class moved onto the bridge pose, Whitney didn't even consider her cock, causing the front of her crotch to proudly show off her now full mast stretching in her gray yoga pants. Not only that, the musk emitting from it allowed everyone to show off theirs as well.
Yes, the musky smell of pre staining Whitney's tent and the growing stench of alcohol began arousing the rest of the class, including her close friends Anna and Gina, causing their own yoga pants and leotards to tent with newly grown male genitalia. Deep breaths became soft moans and quiet grunts turned into snorts as they continued.
"Mmmm... Okay class, let's partner up and get some of our other... stretches done..." she says trying her hardest not to moan as she unconsciously gropes her newly grown balls through her leotard. As everyone paired up, it was clear that the arousing smell of musk and Hogbrew had clouded their minds enough to the point they didn't even realize they were practically male now. Though the smell of Hogbrew wasn't enough to plump them up like Whitney, their breasts began deflating to the point where they now had man boobs in the place of their womanly breasts.
Despite being told to pair up, Anna, Gina and Whitney grouped up, though there was enough in the class to make one group of three. Whitney sat down and splayed out her flabby legs to stretch forward, but was a bit surprised when Gina dropped down in front of her, crawling towards her and eyeing her tent. The plump mother was about to say something when she felt Anna already pressing up against her back, though it felt like her whole body as pressed up against her than rather just her arms pushing. That's when she let out a surprised snort when she felt a curious tip poke against the seat of her yoga pants.
It all happened too fast as Gina began sucking on Whitney's cock through her clothed tent and Anna shoving her own clothed erection up her covered hole. The three began rocking forward and back as Whitney simultaneously got a blowjob and took one up the ass from her best friends.
The rest of the class wasn't so different as others were already doing the same, some through their stretching yoga clothes and some already stripped naked to show off their new male rods. The instructor was showing off her flexible body by fucking one of her naked students, blowing off another, and pumping two other's tents at the same time.
The classes had paid off for them as they went on with their increased endurance until finally the class as a whole climaxed together with cum being splattered against the walls and mirrors and filling asses and yogawear alike. As everyone collapsed into one big pile, panting and snorting, the light of the climax faded, though the stuffy air of musk kept them aroused and unaware.
"Whoa... I think... that was a good class today guys... I hope everyone will bring a nice erection and fucking next class as well!" Laura, the instructor said to the class. None of them even noticed their ears had grown just subtly pointed.
