Origasmi

Ashley threw Heather's legs over her shoulders and pulled her to the edge of the bed. Heather watched her fiddle with her equipment until she slid home.

Heather grabbed hold of Taylor for dear life, teeth grit against the urge to scream. “Fuck, origasmi is the best, isn't it?” she asked the younger girl. Heather realized they shared a position, legs raised while the Woodsens saw to their spread pussies.

“What the hell is ooooh!"

Heather hadn't realized it at first, but the dildo's stylized head wasn't for aesthetics. Its tip flared upwards, and when Ashley's hips rolled at the bottom of her stroke, it poked her G-spot.

“'Origasmi' is what we call a bunch of the more athletic positions,” Hannah laughed. All three girls had started laughing when they saw Heather go cross-eyed around the dildo. “You know, 'cause your partner's folding your body and moving you around however they like.”

Ashley smirked. She bent Heather's legs back while pulling out. “Like so.”

"I ssssee."

Heather adapted to the dildo a little better each time, spreading around it on the way down, gripping it on the way up. It was stiff, not like flesh. Not the way a guy's dick normally was.

“How are you feeling?”

“It's... pretty good. A little, nnh, slow for my taste.” Heather smirked right back. If you think I'm gonna let you call all the shots, Ash...

The blonde's grip on Heather's knees tightened, and what had been a slow rocking, became the casual slap of flesh on flesh, became an honest-to-God fucking that rattled Heather's teeth. The dildo's stiffness was a revelation. If one of them had to change shape, it expected her to give, and in the meantime it'd give her one hell of a ride.
