My Bestfriends Boyfriend

You've gone away to a couples retreat with your girlfriend, your best mate and his girlfriend. You head to the sauna to relax, to find your best mate's girlfriend alone in the sauna in complete relaxation. She's wearing just a towel and has her legs wide open, and she's completely unaware of your presence, so you take a cheeky peep up her towel. Once she notices you, it's not long before the two of you decide to get a bit steamy in the sauna. Let's hope your partners don't catch you in the act!
