My husband and I have had a few fun adventures in our marriage. We've gone to sex clubs, had some FFM threesomes and played with a few other couples. I've always had fun doing it, but was never able to orgasm in the moment.
The nervousness, the anticipation of something so dirty, forbidden and fun always gave me butterflies in my stomach. Just thinking about rolling around with someone's unfamiliar naked body and hearing various people moaning from delight gets me so wet.
