Because I like the idea of nik being a size queen/anal gaper, I have to say Nicholas would also enjoy having a belly bulge. He just likes the idea of something so big and thick leaving its mark inside him while he grinds on it. Hands over his stomach, basically rubbing himself through the outside. He doesn't do it often just to be safe but fuckk when he does he cums so much and so hard.

The second person i believe would be big into belly bulging is Maki but because he'd like to see his own cock bulging through someone else's stomach. Fuck imagine Euijoo crying because hes being fucked so deeply by Maki's thick long cock digging into his guts and its so noticeable because Euijoo's waist is so crazy small. Maki's cock showing through Harua's stomach??? having him hanging off his dick like a rag doll...

I have one more person who would like it but be scared of it at the same time. Jo. Are you kidding me, Jo is a little pervert who's probably seen it in porn and then has had a hunger for it since then. Buying himself sex toys to see if any of them are long enough to bulge through his tummy. he'd own so many toys because he buys the sizes cautiously, buying an inch bigger each time to work his way up slowly. he wants to be safe about it but once hes found the perfect size he's constantly giving himself a belly bulge... crying and drooling over huge toys while he's bouncing on them while they're suction cupped to the floor. kei finding him.... watching as his baby destroys his hole, jerking off to it.. noticing the bulge and connecting the dots,, cumming in his hands because fuck his own dick is a little bigger than the toy in jo's hole.
