Pool-side blowjob.

When Katsumi and Julia returned to the patio they were treated for a pleasant surprise. At least for Bill and me -- we were sitting at the side of the pool with our naked wives kneeling in the shallow water between our thighs, slurping away at our cocks.

"Hey, girls," I waved at our new friends, "join us in the pool!"

I half expected them to hesitate and decline my invitation but then again after the tryst in their hotel room earlier they seem to be open to idea of swinging.

"Hi," Julia replied, as she and her best friend slipped into the pool to have a closer view of the action.

Emma paused, pulling her husband's thick cock from her mouth, and smiled at the girls. "Do you want to try? There's enough for everyone."

"Actually I never gave a blowjob before," Katsumi answered shyly.

"I've only done it a couple times with my fiancé," Julia admitted.

"Well, we can definitely teach you to give toe-curling head!" my wife laughed with my saliva-coated shaft in her hand.
