Hiya Guys n' Gals, OP here! First up, we'd already met before, gone on a couple of dates etc, but this was never exactly a romantic thing. Second, I said "Hell no!" (seriously!), yelled at them both for a bit, then left. Third, while many people may be into sleeping with married people, threesomes, etc, I'm not, because it gets too complicated (the whole point of this was to AVOID complications). So yeah, little rant over.
