Comfortable now, both naked, walking around the hotel bedroom, happy and smiling after our first proper session together. We each showered and shaved.... Mike asked if we could swap underwear for the evening. Strange I know, but it would be a turn on, not only for the evening, but also something for the future. Every time I wore that particular pair of pants, I would know Mike’s cock had been in them. I picked out a pair of my tight orange pants, and he passed over a pair of dark coloured. I had been married for over two decades and had always been faithful, but I felt I needed a new experience, something to put some life back into the old dog. I got home at around eleven o'clock that night. Thankfully everyone in the house was asleep. So I turned on my laptop, navigated to google and created my profile on Plenty of Fish. I got to relationship status and paused. I took a deep breath and hit single and entered looking for casual, no commitment in the intent section. I debated. The manager introduced himself as Rick, he was a very tall, very fit looking black guy. He explained to us the house rules as we had a drink to relax. “Now there are different types of rooms throughout the club, catering to all sorts of fantasies and desires” he told Kate and I as we looked about the club, some men already giving Kate a stare and smile. Rick showed us to the back rooms where there was a bed inside, telling us they were private rooms if we wanted some alone time with the other. I sitted on it carefully and moved up and down."Lay down on your back", she said. I did as she asked me to do. She went over me, ankled my legs up, slided quickly inside my hungry butt, and she started to fuck me rough. I had to to take breath very fast, cause that dick just killed me. So I moaned lightly. She moved her upper body down, pressed my legs beside, and started to kiss me horny. I kissed and kissed her and felt like I´m in heaven...noticing all the time how her dick moves fast back.
