Lower she goes, ass in the air to welcome his cock, that's the way it needs to be. Nothing better than going balls deep hard and fast up her ass. Let that tight ass drain your balls.
I've been the 3rd guy on top. It's great when the couple start to hold onto each other closer... The lower she gets, the more those cheeks spread. (see 3:50).......At 7:30, I love how the 3rd lays beside the husband and keeps plunging. Imagine laying beside this guy during those last 30 seconds.....Just listening to him clap her ass cheeks until he finishes.
