I recently in love with this kinda situation As the topic stated i wan't a sex scene while the uke/seme is talking on the phone, but while talking on the phone he is affected by the intense pleasure that he speaks wile moaning and the people on the other line are wonder what's wrong with them. I Dont Want them to be talking on the phone and not be affected by there partners act of pleasure, because its make it look like there partner is not good enough to pleasure them.
In doesn't necessary have to be sex, it could be a blow job or a hand job... Just want them to moan in pleasure wile talking on the phone and can't concentrate cause of the intense pleasure
I Hope People Could Give me Some Recommendations

Mimurake no Musuko but he is talking with another sexfriend, so if that doesn't matter....

and I'm almost sure some oneshot from Est Em had it, but not too sure. it was either in ultras or red blinds the foolish. But again, he was talking with another sexfriend...

I'll Check Them Out, it Really Doesn't Matter Who's on The Other Line, I just want the person who is on the phone to talk during sex with there partner, wile moaning and managing to get out a few words. XD

and Okane ga Nai had a sex behind the door, trying to keep quiet

Hmm. There's the secondary couple in Keep Out (KISARAGI Hirotaka) who has a conversation with one of the main character on the phone while... ya know. I don't think he moaned wildly, but I remember it was pretty hot.
