A Calorie-Counter Vibrating Double-Ended Dildo

At first glance, it looked like a sex toy designed by Klingons, for Klingons. The gentle arc of the double-dildo ran about two and a half feet from cocktip to cocktip. The middle part was smooth, with a digital display, while the business ends got increasingly realistic and phallic, until the last eight inches on either side looked like something from the Monster of Cock series. Two prongs like scorpion stings, loaded with vibrators, were designed to stimulate the clits of both partners at the same time.

"It has a calorie-counter," Rory said triumphantly. "Measures your heartbeat to estimate exertion. The vibrators are tied to the counter; the harder you fuck, the more calories you burn, the better it feels. Each section can rotate independently, too, so you can use it in a bunch of different positions."

Alex rolled her eyes, glad that her lover couldn't see it. Rory was a gadget-hound when it came to exercise equipment. She liked to try out lots of things, and Alex fondly remembered the inflated bouncy balls with dildo attachments, the mechanical rowing machine-cum-sex machine, the sports bra with the little vibrators in nipple-pockets...

"So, how do we want to do this?" Alex said. "Do you want to scissor, or is there going to be some kind of harness?"

Rory smiled. Then she told her.

Which is how, a few minutes later, Rory found herself laying tits-down on the weight bench. Velcro straps around her arms and legs held the woman in place, though Alex was sure she could pull out of them without much effort. It was mostly just to keep Rory from moving as Alex lubed up the toy and slid it into her own pussy...then lined up the other end with Rory's dripping snatch.

Alex was giddy with expectation as she eased the toy into Rory. There was a pleasant thickness to it, but more than that, she could feel the shift in tension as she fed the fake cock into her girlfriend's slit. Not that Alex expected Rory to take the whole length. Alex could see Rory's hands clamped onto the cold steel support of the bench as Alex braced herself one hand on Rory's msucular ass. The other fed the fake cock in until the little arm with the vibrator touched Rory's clit.

"You okay, babe?" Alex asked as she rubbed Rory's ass.

"Fuck, I'm full," Rory said, and flexed her tight body. Alex could see all the muscles in her back stand out for a moment. "C'mon. Fuck me. Burn those calories."

"You got it, lover," Alex said as she clamped her pussy tight and began to move her hips.

They had tried strap-ons before. The main problem for both of them was that penetration alone was never enough to get them off. As the dildo registered the movement, though, Alex felt the tingle as the vibrator clicked on. The big-bottomed woman pushed the dildo in and out of Rory's cunny, and huffed a little at the pleasant vibration. Experimentally, she tried to thrust a little faster, and the tingle grew more intense.

"Harder," Rory said, her ass flexing as she pushed back against Alex's thrusts. "Faster! I want to feel it."

Alex grinned and picked up the pace. She could feel it in her abs as she slammed her abs forward. Her pussy ached as she kept her cunny clenched against the end of the dildo in her own cunt. The better to fuck her with.

That triggered an odd thought in Alex's mind. Her hands slid across Rory's hips. Alex could feel the burn in her abs as she flexed, the buzz of the little vibrator on her clit a constant stimulation. Yet what ran through Alex's mind was...something else. Something deeper. Something she had to find the words for...

"Rory..." Alex said, as her breath came in little huffs. "...I...want you to know...I love you."

The darker woman turned her head and grinned.

"I love it too, baby," Rory said.

"No, I mean, I...love...you," Alex grunted as she pushed the dildo in deeper than before, hard enough to make Rory's body jump, the velcro straps giving way a little. Alex's hands had the thin hips in a **** grip. "I'm...in...love...with...you. I...I...aaagh!"

The last thrust was too much. The velcro straps gave away as Rory was half-pushed off the bench, and Alex held her there, her hips jerking spasmodically as the vibe kept going, fucking herself on the dildo as Rory was getting fucked. The little animal cry that came from Alex's lips as she went over the edge was like a wounded animal finding release from a trap.

Rory laughed, a light tinkle of mirth. With athletic ease, she twisted and turned...and the two women found themselves both seated on the weight bench, Rory's legs over Alex's, face to face, tit to tit, the dildo still now but still buried with an end in both their pussies, the little digital meter showing how many calories they'd burned.

The dark, trim woman laid her arms around Alex's neck. She stared into the auburn-haired woman's eyes.

"I love you too, Alex," Rory said. "You're my one and only."

Alex, already flustered, felt the flush spread across her cheeks and chest. Her ears burned, and the hairs on the back of her neck stood up.

"You mean it?" Alex said.

Rory smiled, and drew her lover's face close.

"From the very first," Rory whispered, her voice husky, just a moment before their lips met.

Down below, their hips began to move. The vibrators began to buzz, slowly. The calorie counter ticked over...and neither woman cared what it said, so lost were they in their embrace.
