The two girls stood in heavily disgusted shock at what they had just been told.
"A Sexual Workout." the instructor had said.
"What the hell does that mean?!" Rachel demanded.
"It means you better start stripping off your clothes or we'll resort to more... drastic measures." the instructor replied, two soldiers starting to unzip their flies as he said "drastic measures".
The girls begrudgingly strip into nudity before being put into an "appropriate outfit": identical lingere sets consisting of a lacy cleavage boosting bra and a pair of crotchless panties.
"I am not putting that on-" Rachel was cutoff by a fly unzipping, to which she begrudgingly put on the slutty underwear.
Both girls submitted to the task and rowed some specially designed rowing machines. The mechanism jammed a six inch rubber rod into each girl's clit as they rowed, going in and out, in and out.
"Ohhhhh.... ohhhhhh Samus baby, k-keep going." Cailin said to herself with her eyes closed in order to make this situation less unbearable. She pretended it was the fictional bounty hunter with a strap on, but it was really a contraption for pheromone harvesting with a window that passersby could look into.
"Ahhhh...." Rachel moaned in sync as she started rowing faster on demand of the instructor.
"Oooohhhhhhhhhhhhhh...." both nude girls moaned as their nipples popped through their bras.
"Intensify arousal." the instructor said.
Devices were strapped to each girl's breasts to massage them as they rowed, making them start to ooze out their clits and drool almost uncontrollably.
Then there was the climax.
"AHH.... SAMUS... AHHHHHHHHH!" Cailin squealed out as thick white ooze blasted across the seat of the device.
Cailin took a breather as she stopped for sweat collection, while Rachel kept on going, harder and harder.
"E-em..." Rachel moaned.
Cailin cocked her head.
"Emi-Emil----" the blonde moaned harder as she yanked on the machine to near breaking point.
Cailin looked on as a white puddle formered at the crotch of her waifu's stand in.
"OHHHHH... EMILY TAKE ME NOW! AHHHHHHHHHHHH!" Rachel yelled as she let out a massive spleuge.
*****************************
Emily.
It rang out in Rachel's mind as she was wiped down and unrestrained.
Emily.
It was in her head as she showered, Jamie trying totalk with her in vain.
Emily... Emily... Emily...
It rang relentlessly as Rachel tossed and turned in her bed....
