The first ever Sam-off

"Let's have a good old fashioned Sam-off! Karishma versus Chris!"

"A what?"

"We have a Sam right here, we take turns getting him off. The one who turns Sam into a fucked mess wins!" Nebula announced dramatically. There's no way they'd actually agree to that, right...?

The temperature in the locker room, normally kept at a dick shriveling chill, suddenly got uncomfortably warm for you. Something in both Karishma and Chris' eyes turned predatory as they looked at you. Karishma's pupils shrunk considerably as she sized you up hungrily, while Chris was breathing heavily through her nostrils, cheeks flushed bright crimson.

"Is that alright with you, Sam?" Karishma said, in a breathy whisper you never heard her use before, stepping towards you slowly. Karishma ran a fingernail underneath your chin, raising your gaze to meet hers, inches away from your face. Her pupils shrunk to an unnatural degree as she looked deeply into your irises. Your cock reacted instantly to her overt lust.

This was information neither Nebula or you knew, but the Japanese branch of the Society had perfected an AI love doll, designed to mimic your nerve responses. This was tied to a scoring system, ranking who would be your best lover. While the names were anonymized to prevent drama, two American members constantly battled for the top rank. These two just so happened to be the two girls standing in front of you right now. Karishma, whose parents owned the importing company responsible for smuggling said love dolls to America, studied neuroscience to discover your body language patterns, in order to maximize your pleasure. Chris, however, simply trained nonstop, learning what tricks you liked best from past experiences.

Nebula, totally oblivious to what she just unleashed, pumped her fist. "Both contestants will get five minute turns to do anything they wish to Sam! To keep things fair, Sam will be blindfolded and bound! Any sexual technique is allowed! Winner is decided by Sam's reaction and orgasms experienced, scored by an expert judge, namely myself, Nebula!" Nebula declared officiously. Karishma's lip curled up to reveal pearly white teeth, grinning sinisterly. Chris licked her lips seductively.

"...Yes please..." You said, your dick answering for you. Karishma giggled coquettishly. Chris nodded wordlessly, too focused on her prize to speak.

"Perfect! Contestants prepare yourselves for Sam-tis-faction! Sam, you stay right here..." Nebula wrapped a towel around your head like a turban blindfolding you, tying it off tight enough to dig into your ears. Nebula guided you backwards towards a bench and pushed you down on your ass. Nebula pulled your wrists behind your back, binding them with another towel. Nebula gave you a thumbs up that you wouldn't see, patting your cheek affectionately. Nebula skipped away to referee the contest.

You waited anxiously. This felt like something out of a dream. Two girls were now sex-fighting over you, about to try to make you cum multiple times. Who else was going to be doing this with you in the future? Your mind flashed to every other woman you had a sexual fantasy over... Dana... Mrs. Pill... Chris' absolute cougar of a mom, Joylne... man, that was your oldest crush... the way she'd watch tv with you two wearing only a towel... Chris always got so mad at you when you stole peeks at her... God, what was taking Nebula so long?

"Three. Two. One... Go!"

A single set of footsteps approached you. They must had taken off their shoes and socks beforehand, because you heard the patter of bare feet. But why?

Your question was answered as a heel pressed firmly onto your balls.
