Nope, scare him away to be the cuckold.

Chester's grey-clad roommate is cupping one of your jiggling tits with one hand, while he furiously masturbates. You have no intention of letting the creep into a moment that only belongs to Chester and yourself.

"Shh." you gesture between two thrusts, and you push him away with a sneer. The man takes the hint. He shrinks away and retreats to his own bed. You nod, and continue to bob up and down on Chester, no longer paying attention to him.

Your boundless energy continues to invigorate Chester. Your mind is filled with pleasure, and your pussy with Chester's cock, and an eternity of wonder passes. And then Chester has recuperated. You almost forgot how big and firm Chester had been before you milked him the first time, but now you find new heights of pleasure when his fuckmeat firms up. He begins yelling wonderful obscenities about you being his perfect fucksleeve again and then he shoots a second load into your burning, waiting womb.

Yes! You scream a loud "CHESTER!!" while he roars "MY GIRL!!" as each of you rides a high of endorphines, and then relent with a pleasant shudder. You slow down the rhythm and slide off, to face your exhausted lover and kiss him. His previously blue eyes are now appearing maroon inside your color-vision.

Oh cool. Your theory is right: The color-vision you have of people and their properties, only includes people's eyes after you fucked them.

Oh damn, you hadn't checked when Chester's eyes switched. Or had they changed gradually? Too late to find out now, it seems.

"Oh girl, that was amazing." Chester whispers hoarsely and tries to embrace you as he kisses you back. "I can't believe how perfect we fit together! You are amazing, um..."

"Mygirl?" you ask with a lopsided smile, slipping out of the bed. "Sure, call me 'mygirl'. Like, my name is totally just a variable combination of letters."

"Christ..." Chester stammers and you smirk: "Guess again? Maybe my name ends with an '-a', you know?"

"Um, ummm... -ahh, Christa?" He is the spitting image of an embarassed dude now. You laugh, and are surprising yourself with the clear, bell-bright sound of your voice. "Oh wait, mAAAYbe my name ends on '-y'."

"Kkkk... kristy?" he manages, and you laugh again, as you put on your swimsuit. You give John-the-pervert-roommate (who is now smirking again) another withering glance, before smiling and blowing a kiss to Chester. "Don't bother your pretty head, Chester, my name is Emcey. Random combination of letters, remember? Don't be ashamed, this was a fun ride. You're a heck of a stallion, and I can't wait to host you in my stable again."

And with that, you open the door and bump it into another man, who got rid of the bottom half of his pitch-black swimsuit and is beating his meat right in the hallway. Another cutie... he is a head shorter than you, but his cock is no less impressive than Chesters, and standing like a ramrod. "Ah! Look, I can explain..."

"No need, you were enjoying our background music, weren't you?"

"Right, no, hey wait, YOU are Emcey? I just heard there was a girl with Chester, and that's you?" He stares you up and down in appreciation, his eyes lingering long on your tits and your navel cutout, before staring up into your face again.

"And you are?" you inquire and your two smaller tongues emerge to lick your lips.

"Me? Abram."

"Okay Abram, I'm free next Wednesday again. Where do YOU want to hang out? Same room, same time?"

"I'll let you know. Nice to meet you, Emcey!" he answers smoothly, then he stretches out a hand. You give him yours, and shake firmly. Strong grip, you notice, before you walk away, noticeably bow-legged, with a smile on your lips.

Behind you, a dispute breaks out between the three roommates: "Chester, how did you forget Emcey's name?? She won't look at you even with her ass again!" - "Shut up John, you think I didn't notice you tried to grope her while we were fucking? What the heck?" - "That was no problem last Thursday. I had her first, and she enjoyed it!" - "Guys..." - "Oh, and that's why she hasn't visited until now, right?" - "Guys! Next week, I'll ban you fuckers from the room, because you are going to screw this up!"
