Let her feel the effect she's having

You return the hug, tightly, letting her young body press against your older, but still athletic form. Without question, she feels your sizable cock pressed against her tight tummy, and you feel her muscles stiffen. You don't let go, though--if anything you squeeze a little tighter and rotate your hips, really making clear that this is on purpose. She stiffens even further, and you lean your lips near her ear.

"It's truly my pleasure," you whisper to her, "and I hope yours, as well. Any time you want to come, Suzy and I are happy to have you."

You release her and see that she's flushed--is she excited or embarrassed... or both?

"A-a-and where is Suzy?" she mutters, her eyes flickering to see the enormous bulge in your bathing suit.

"Oh she's out of town on business. Happens from time to time." You again let your eyes wander over her form, making no secret of your desires. "And where's your boyfriend, didn't you want to bring him over to enjoy the pool as well?"

You're actually not certain she has a boyfriend, but she has brought a male friend over to the pool in recent weeks, and they seem particularly close.
