i think this is it
nope the seme had black hair + it was a senpai seme x kouhai uke at work setting. not sure if the uke brought him back to the seme's home or to a motel.
it's shitsuji kanzaki no yuutsu thanks!
does anyone know that manga where the uke drinks together with his senpai at work and the senpai pretends to be drunk so the uke helped him by bringing him somewhere and the uke got curious decided to check out the size of the senpai's dicku since he was hard? it turns out the seme was just acting drunk and shy while they were drinking
