Men breed with other men, in which one of them becomes the other's bitch. Basically when 2 or more men get close to one another, the will soon be an alpha among them. The rest will become bitches. A bitch is basically a man whose incapable of impregnating any other man. This is because his testicles have reengineered themselves to produce an egg for producing offspring. Other notable features are that their chests soften and become milk filled breasts, their voice raises in pitch, becomming more feminine sounding, and a womb is formed at the base of their cock. The only other change is that their urethra will widen significantly in order to allow an alpha to penetrate them all the way into their wombs.
The thought of having some other guy mount you, as his dick pushed itself into your own horrified you. You hoped that you wouldn't ever have to become some other man's bitch. But to your surprise, Maria answered. "Yep, it was already on my mind from the start. How would Eric like a mate?" She asked Stacy.
If Eric was who you thought it was, than this was the same boyfriend Stacy "stole" in your reality. You sorta knew him. And one thing was for sure though. The guy had a reputation for being massive in the pants. "Are you sure? I mean, Eric would fucking love it, but would your guy be ok taking something that big? I'd hate for him to get hurt." Maria was not gonna back off now though. "Dont worry, this soon-to-be bitch is more than able to fit him, I have a good feeling about it."
"Well, you never seem to be wrong about your crazy feelings." Joked Stacy. To your shock, you were suddenly set up to become Eric's bitch. Wait, why would you even become his bitch? Why can he become yours?" You wondered. However someting in the back of your mind already knew that was an impossibility. If you two were to meet up 100 times, you would become his bitch every single time. In your sadness, you fell down onto your knees, cursing your luck. "See, he is already assuming a bitch's posture" pointed out Maria. Apparently, the reason why men were either standing or walking on all fours was because of their status. Bitches crawled on all fours while the alphas walked on 2 legs. Sure enough, you couldn't bring yourself to stand up. It wasn't that you physically couldn't, but you felt very self conscious about doing so. It was a similar feeling to how someone wouldn't want to just strip naked in pubic back in your old reality.
"Hey, I'm free if at the moment you want to bring him over to meet Eric." Offered Stacy, which Maria quickly accepted. "If that is alright, I would love to. I bet he is really eager to meet Eric too!" She said happily, gesturing in your direction.
