Hello, as the title says, I'm looking for a certain yaoi, so I hope you can help me out. c:

Pretty much from what I can remember, it's a manga involving two businessmen. (There's a prequel and a sequel)
The uke (as much as he doesn't think so), gets forced/raped in the beginning of the story (in the workplace, and as far as I remember, it's up against a door).
Either way, the uke hates the seme for a while, and at some point tries to get revenge at him. The uke brings the seme to some sort of s&m club, and he tries to humiliate the seme (thinking it's his turn to become the bottom), and of course it all backfires and ends up with some smexy sex in the end. 😛

The art reminds me of Minase Masaras. but I can't find it anywhere.
The seme has glasses, and blonde hair (if I remember correctly), and the uke has brownish hair. Physique wise they're quite alike.

I hope this helps, and I'm sorry if this is put in the wrong section or whatever, but I'm new. |: I hope it doesn't seem too confusing, but it's because I read both the sequel and the prequel, so I don't remember which details belongs to which "story".
Anyways, thanks for your time!

Is it Shigekiteki na Kankei and its sequel Motto Shigekiteki na Kankei?

That's exactly it! Thank you soooo much! :3
