Before my wife and I got married, we had some fairly wild sexual adventures (we've had some since our marriage too but those are different stories). I knew I might be biting off more than I could chew when my future wife informed me during our first date that she masturbated at least once daily and often more than that. I ended up fingering her ass later that night as we made out, and she was the first girl I'd ever been with that was so intensely turned-on by having her ass penetrated. Since then, our sex life has been quite a roller coaster ride, with more thrills than any amusement park I've ever seen.
Our first sexual adventure together involved inviting a female friend into our bed, and exploring my wife's bisexual side. My wife Raquel, is a small Hispanic fireball, slender, with curly long brown hair and the most amazing heart-shaped ass. Her mouth is one of her sexiest features, with rich, full lips that look fabulous wrapped around a cock. As I was to find out, they looked pretty amazing wrapped around a clitoris as well!
Amy was a friend of Raquel's from work, and the two had been talking about sex since the day they met. They traded stories about their sexual preferences and pleasures, and at some point started talking about threesomes and sex with another girl. Amy had messed around with another girl once before, though this had apparently mostly just involved kissing and touching. At some point, Raquel was describing me, and our sexual relationship, and they discovered that Amy and I had actually met at a bar a few months before. I was born with only one hand, and my shortened left arm tends to be somewhat noticeable; it stops around the wrist, but is rounded and looks much like a short, thick penis. I had joked for years about penetrating a woman with it, using it like a dildo, but Raquel was the first woman that ever took me up on the offer. It was a little awkward, but when her pussy was wet enough, my arm slipped into her almost up to the elbow, and she would moan with pleasure. When I then started wriggling my wrist inside her, she literally went nuts. This story was told to Amy, and reportedly Amy got pretty excited at the idea.
