More Lessons are needed!

Jane does her best to pleasure Dee Dee.
This guy is nuts!

Her co-worker doesn't moan enough, it seems.

"Do it better," he says, dunking her again.

Another attempt.
Another 'failure.'

This, of course, keeps disorienting her, making her not exactly working at peak performance levels.

One last failure leads to a long dunk and he's had enough.

"You're going to regret that performance," he says, leading her away.

Time passes slowly for Dee Dee.

This bondage isn't pleasant and now the fun distraction of having her tits sucked on by her friend is over.
She can't look around much to see anybody, pretty much stuck looking where he pointed her.

She hears a splash and is hoping this means that he'll untie her.

Instead, he swims up behind her and begins to pleasure her.

"I have to finish the job that your co-worker couldn't finish," he explains, "Lean back and let me do this."

Even if she could resist, she sure as hell didn't want to once his fingers started thrusting in and out of her pussy!

It isn't long before she cums for him!

She pants from the exertion and release, sighing happily.

"I'll let you down once I set up your friend's next lesson," he explains, swimming away.
