We are a straight Caucasian couple looking to spice things up a bit. We have a healthy sexual lifestyle in which we have been exclusive for 30 years. My wife expressed an fantasy and I shared one as well. In this case, she wants two men at once where i am having sex with her but an additional male, you, would massage her breasts and stimulate her clit. I wish I could do all of that, but I only have two hands. :) She just wants to build out the experience. She also is ok if you just watch. I think my wife remains pretty hot for 50. I suspect you would too.
