Help me find this manga please!

I was about to recommend a yaoi to my friend, but I didn't find the link anymore, so I'm counting on you guys! I read it on mrm and it was about a guy who broke up with his girlfriend. To console him his friends paid him a visit and found a video tape where his ex is doing him with a strap on (lol was that how these things were called?) After that he had a three way with his two friends who were really triggered by their smexy friend. It was really smutty and a one shot!Please help!
