I'd like identification of certain manga from my scattered memory if possible.
Unfortunately I don't really remember much about plot. Seme is older than Uke and rich (possible head of some kind of company or group), uke is younger (iirc highschooler) and there should be a scene where uke iserts bottle in himself to "get used to" feeling before their actual first sex.

Is it Hidoi Otoko?

No, art seems to be different.

....
Wait, looks like the name was right, it just linked to different manga with the same name.
Thanks.
