Lesson number two.

"Are you girls ready for the next lesson to please your future husbands but also yourselves?" Emma asked, winking at Bill.

Julia and Katsumi looked at each other before hesitantly nodding.

"Boys, do you mind lying down?" Emma asked.

Bill and I knew what she had in mind and we grabbed some beach towels and spread them on the patio before lying our backs on them. Our erections stood tall and proud like flagpoles on the Fourth of July. The two Asian girls already knew what it felt to have our thick cocks on them but it was their first real look at how intimidating they could be to a pair of petite young women.

"You don't want your future husbands to bang you for a minute then kiss you good night," Sam said as Emma and her climbed out of the pool, giving Julia and Katsumi the view of my wife's noticeable baby bump.

"You want to enjoy the love making as well," Emma continued as our wives stood over us.

The two Asian girls intently watched from the pool our wives lowering themselves onto our cocks, leaning forward to rest their hands on our chests. The girls let out moans of satisfaction when they sat on our balls, their pussies swallowed the last inch of our shafts.

"Oh my God, I can't believe we had their big dicks in us," Katsumi blurted out before she gasped, realizing what she had revealed.

"Don't worry girls, we know -- that's why you're at this resort, remember?" Emma grinned as she started to grind on her husband's cock. Bill reached up and played with her huge tits dangling in front of him.

Our wives proceeded to show our new friends the various positions to ride their future husbands, all without our cocks slipping out of their hot, tight cunts.

"Would you girls want to try?" Emma asked after she recovered from her latest orgasm. Sam was still bouncing off my cock, bringing herself to climax for the third time.
