It's driving me crazy!

Hey y'all I need help finding the name of a manga about an older uke and younger top. It's a bdsm one and the uke was only wanting to find someone to teach him because he's wife was into it? I think??? Also one of the scenes of it is used by a translation group with the word Cupid. They put their name on the ukes ass.

I know I read it and dropped it because I became uninterested. But now I am and it's driving me crazy I can't find it! (╯°Д °)╯╧╧
