My wife was dating my friend when we met

My wife dated a friend of mine for a year or two when we first met. I don't know a lot of details about their time together, but I know that they fucked bare and that he came inside her multiple times. I know that she also sucked his cock and that he came in her mouth, though she told me she didn't swallow. I find it arousing that I know someone that fucked her repeatedly, bare, and filled her pussy multiple times. It's exciting to imagine his bare cock penetrating her pussy and pumping in and out until he emptied his balls in her, before I dated and fucked her.
