Generally it was MY(!) decision getting fucked by a stranger. My husband stimulated this fantasy over years and one of my thoughts (a lot oft thoughts by the way) was: It must have an end! So I did it - in front of him, gave him what he wanted to see: My heeled legs wide open while a big dick pumped my brain out. It was a point of no return but these are (in my opinion) mosty the best decisions because after that you have a setting and no day-dreaming any more.
