At first he would immediately put his partner's pleasure before his own because that's just his nature at this point but the more he got into it the more he would forget himself and the more ROUGHER he would get~!
Until it finally gets to the point where he would manhandle his partner easily to the bed (no matter their size because tsuki's buff af) throw them against the headboard SO HARD their ears would probably ring, and slam his dick into them before they could regain their bearings~!
Our poor, repressed and frustrated Sargent is now reduced to a beast as he fucks his partner at a brutal pace~! He's wound so tight he's now only chasing HIS pleasure and pounding the body beneath him into the mattress. His partner would be held so tight and secure by those beefy muscles of his that they probably wouldn't be able to move or stop him if they wanted to~! The only sound in the room would be the squeaky, rhythmic creaks of the bed, the loud slapping of skin on skin and Tsukishima's ragged and animalistic breathing~! :>
