What's the name of this BL/Yaoi? Pls answer!

So, I saw a post in twitter I think it's an omegaverse plot? It's a manga, and the seme and uke already have children that are teens. They were caught by their children (having sex) one time but the seme continued, not even bothered. While the friend their children bought awkwardly greeted the uke who's being pounded by the seme. I really want to know the name of this manga because it seemed interesting, I hope someone replies!

P.S. I didn't get the name of the manga in twitter because my phone lagged, I didn't catch the name.
