They chatted.

"It's going to be odd having sex with just one man after leaving here," Julia sighed as we all laid back and stared up to the ceiling.

"Yeah," Katsumi agreed.

"Girls, take it from a former swinger, there's nothing wrong with making love to only your spouse," I added.

"But Sam's gorgeous!" Katsumi whined.

"Oh my God, yes!" Julia agreed. "Emma too!"

"Both of you are gorgeous too!" I chimed in.

"Awww! Thank you!" the girls beamed in unison and rolled to their sides to smile at me.

"Your husbands will never get tired of making love to the two of you!" I smiled back.

"We know," Katsumi sighed. "I love my fiancé and he does make me cum but..."

"... he doesn't make me cum multiple times," Julia continued, glancing at my flaccid cock.

"He just goes to sleep after we have sex," Katsumi adds.

It was quite obvious the BFFs knew each other's sex lives quite intimately and were just unleashing their complaints to get them off of their chest before their big day, which I didn't mind because it put me in better light than their fiancés.

"Mike, how do you stay hard for so long?" Julia asks.

"Even after you cum?" Katsumi wonders and notices my cock starting to stiffen.

"I don't take Viagra if you're wondering," I chuckle. "The simple answer is that I love having sex."

"Seriously?" the girls said perplexed.

"Most men just think of sex like a sprinter, dashing across the finish line as soon as possible," I explained. "But I see sex like a marathon runner with strong endurance and hold a steady pace -- which was something necessary during my swinging days if I wanted to please multiple lovers or even just one lover like my wife for long duration."

The girls nodded, understanding my analogy.

"We wish you could teach our fiancés," Katsumi wished, looking at her friend.

"That would be very awkward!" I laughed. "'Hey, guys! I'm Mike and I fucked your fiancées for a week in Jamaica and they asked me how to teach you how to fuck them properly!'"

"Sure if it means we can get multiple orgasms just from having their dicks in us!" Julia giggled.

"Speaking of multiple orgasms from having a dick in us..." Katsumi grinned as she stared at my reinvigorated erection.

"Ready for round three?" I asked.
