I think that Nik and Price enjoy thigh-fucking, Nik moreso than his lover.
Nik especially loves to get between John’s thighs after they’ve come back from the gym and one spent their time actually working out while the other spent their time fantasizing about the many positions they’d put their S/O in.
It doesn’t matter if John’s hot and sweaty, to Nik, it just makes everything easier because now he doesn’t have to waste time lubing up and can instead just slide on in!
If John gets overstimulated and tries to move his thighs apart, Nik will hold them together with all his might and speed up, causing his husband to cry out and whimper until he’s putty against his chest.
