My Bi-Wife - female - and I just celebrated another wedding anniversary - let's just say we're well into 40+ years married. We've been in the lifestyle for 30+ years and treat sex as a practical necessity of life. But to find a couple that matches us is a little difficult. On a recent visit to a Tampa nudist resort where 'swinging' is encouraged we had three encounters that illustrate our mindset and tastes.
The first was a M/F couple first approached by my spouse while we were in the party room. She found the girl to her liking and the male was agreeable. The young lady was soon devouring my wife's clit and finger-fucking her at the same time; this two-pronged assault is characteristic of those w/experience and a healthy desire to get you to cum. I held my wife's left leg up while the other guy was holding her right leg as we lay on either side watching the female attack this super wet pussy. This session came to a conclusion when they asked that my wife sit on the female's face while this same female was being fucked by her husband. He, of course, was sucking nipples and making out w/my wife who was agreeable to reciprocating; an enthusiastic and beautiful tableau. My job was just to hang back until I could offer assistance if needed.
Second was a good-looking guy that was shooting pool at the outdoors table and had a great body and a fantastic ass. We exchanged some small talk and we both noticed the other checking out each other's cocks. He commented on my cock ring and let slip - intentionally - that he had sucked a few cocks. My wife, knowing me, informed pool shooter that she knew I wanted to fuck him and would like to suck/fuck him while he was being fucked. It was about six in the afternoon so we agreed to see each other at poolside later that evening. We did see him later that evening and watched while he fucked a cute, tattooed young lady all the while inviting me over to fuck his ass. I finger fucked his ass because mounting him was not practical. His anus was literally clamping down on my fingers.
The last was back in the party room on the next day as a young, gay couple entered and the cuter of the two took an instant liking to my cock. He asked if we had any poppers and said that would help him take all of my cock down his throat. My wife searched our ditty bag but realized our poppers were in our ice chest in our car. So she tried to coach him on swallowing my whole cock and how he had to relax his throat and suppress his gag reflex. But he never was able to take all of my cock.
Our desires and approach to sex is what we think it should be after years and years of cultivation. We've gotten better and better over time but acknowledge that the key to fantastic sex is making the other person cum as many times as possible. Focusing on the other's pleasure is the real key.
Sorry for such a long response.
Hundreds and hundreds of men and women. But very few repeats.
