Back to the cabin.

On the way back to the cabin we stopped for a bit to the watch the same couple we had seen earlier fucking on the beach still going at it.

"Oh my God, he's still fucking her!" marveled Julia while she gawked at the older man thrusting madly at his much younger partner from behind.

"He's on Viagra," Bill told the girls in defense of his ego and virility. "He's dying to cum after being erect for a couple hours."

"Hours?" Katsumi gasped. I'm sure she was imagining how sore her pussy would be from being pounded for up to four hours. She already knew half an hour felt like!

We got back to the cabin and found our wives on the deck sitting back on the sun loungers next to the large infinity-edge plunge pool perched right over the ocean, enjoying the sun and scenery.

"Honey, did you put on your SPF-6000?" I joked.

"Ha ha," she replied with mock laughter. As a natural redhead of half-Irish descent with pale complexion Sam had to lather herself with sunscreen lotion and wear a big sun hat or risk burning up like a vampire in a tanning booth.

"Oh, by the way, girls, since our husbands only brought their duffle bags you can use their closet space in our bedrooms for your clothes," Emma announced, putting down her eBook she was reading on the patio lounge chair.

"Oh thank you!" Katsumi cheered.

"Do you mind if we change into our bikinis in your bedrooms?" Julia asked.

"Go ahead, hon," Emma smiled.

"Do you need help unpacking?" Bill asked jokingly.

"No, it's okay. Thank you," Katsumi giggled. He watched the two petite girls walk back inside.

"How did it go?" Emma asked her husband.

"Great!" Bill answered with a shit-eating grin.

Emma stood up, wearing a pink bikini and a see-though knee-length skirt tied around her waist, and walked up to her husband. She glanced behind Bill to make sure both Julia and Katsumi were gone. "Honey, we let the girls be with us because it's our way of thanking you for allowing Mike father our baby," she whispered with a smile, "and with Sam four months pregnant I'm worried she couldn't handle your libido on this island."

"As much as I'll miss being between your legs, Sam," Bill chuckled, winking at my wife, "I'm not complaining about the consolation prizes."

"Do I get a prize?" I joked.

"Yes, you do, honey," Sam replied with a mischievous grin. "Yes, you do."
