So what do we have here? Is the MC fucking futas or is he getting fucked by them?
2 MC's, same guy, different dimensional world versions.
The Magic dimension world MC.
He is a muscle bound warrior who can easily get any of the ladies or any possible futa he might want.
He'll have to earn it of course, their not gonnae spread their legs just like that.
The Sci-fi future dimension world MC.
He is a small, skinny, slightly feminine looking guy, with a big brain and a bigger arse, so far it is mainly mature domineering futas that are interested in him especially his former teacher Nyxi. (She is personal all time FAVOURITE here)
He has a couple of female allies that he has a strong realtionship with, but the BIG futa's can easily break his resistance.
Though the story is rough, my guess at the general gist of it, is that the dimensional barrier between both world are being experimented on and both versions of the MC are being affected by that, so my guess is that eventually he'll be the one to decide the fate of both worlds.
