1) I guess the place might have a policy that customers have to agree with to be clean of any STDs before penetrating any of the employee's, but some probably some don't care about that.
2) He can have enjoyable sex if he gat erect but with the fever he will feel more worn out and sweat more.
3) I guess he probably didn't think he had any other choices when it came to losing his butt virginity.
4) I guess you could search it up but you might not get very nice results.
you forgot 5) they're brothers
There are no std's in yaoi world...lol
(1) Im concerned about STDs? You cant see who's screwing you and you cant do anything if they dont use protection and even if you call for help itd be too late? Though I guess its a general concern for any kind of sex work.
(2) How can he have sex with a fever????
(3) WHY DID YOU LOSE YOUR VIRGINITY THERE OH MY GOD
(4) I disturbingly like the concept of a butt sticking out is this a real thing
