maybe this? the tattoo is on his stomach though
i know one, but the tattoo is on the front on the private parts
thats it thank u so much
ooh this sounds interesting. which one is it?
i'm not sure :(
but i'm sure it's about a S&M relationship between salarymen
no problem.thank u
ok so im pretty sure i have it somewhere in my “alreay read” or “reading” list but i couldnt find it. its this yaoi manga about a dude who has a lower back tattoo. and this shy-er uke sees it and thats all i remember. Oh they also do it in a storage room i think
