Artemis your mind... I'm thinking hccki oops... Kiki just freshly getting that tattoo done and it still stinging when touched but he still works his way around it and trims himself all smooth and proper so he can send his hyungie a little pic he can keep for himself.
Kiki is sitting on the couch one day while hccjek bicker over a game on the playstation and he's being super coy, sends it to hcc just as they're about to start a new round (of wtvr the fuck theyre playing idk). Hcc lifts his phone and instantly goes red in the face. Jek is super curious so he's like heyyy what r u looking at and hcc nearly throws the phone across the room trying to get jek to back off.
It's a cute pic okay? Baby alpha tried rlly hard to get both his tattoo and his cute pink cock in frame. His fingers are wrapped around it loosely and he has rings on each one, gleaming silver and hcc is like "fuck i got him those rings."
+ Bonus points if you hc him as having a bellybutton piercing too (and i fucking LOVEEEE bellybutton piercing kiki).
It ends with hcc's fingers digging into the skin of kiki's hips as he bucks into him like a wild animal...poor kiki can't breathe, can't speak. He's just falling apart on it and it's exactly what he wanted to achieve by sending that pic.
