This is not Lynn, but I have watched the action with her and a close male friend from a very similar angle. Oh yeah. Watching his balls slap her ass as he pounds my wife, and she thrusts back upward to meet his pounding cock, loving it.
I'd post video of wifey with a friend doing this but I don't want to expose her to the entire world... 1 on 1 sharing tho, we can do that...
