Ask her if you could use some of her shampoo.

You can feel the tension in the room. Carly is nervous. You kind of are too. You pass a glance at her. Even in the speedo, her figure is enticing. Her chest pushes against the fabric with the nipples poking through. Her bubble butt sparkles with water drops. You feel a twitch between your legs. Hopefully she doesn’t notice your little buddy coming to life. You try to distract her with some casual conversation.

“So… Carly…” you start.

Carly immediately tenses up as if she had been caught doing something wrong.

“Do you mind sharing some shampoo?” you quickly add.

Carly’s shoulders relax. She smiles, a little embarrassed. “Yeah… of course…” she says, offering to squirt some shampoo into your hand.

“Thanks!” you say, feeling your nerves calm down as well. “I didn’t think to bring any…”

Carly laughs as you hold out your hand. She gives you a generous dollop of hair washing detergent and you immediately lather it into your hair. The follicles agitate the cleanser into a big foamy hat. You playfully give it a sharp tip by pulling the bubbles up. Carly giggles.

“I guess you didn’t bring any soap either…” Carly surmises.

You shrug, “I guess I can use the shampoo on my body too…”

“It’s ok, I have some body wash,” Carly offers. “I mean, if you don’t mind smelling like lavender…”

You grin, “I don’t mind at all…” You hold out your hand to gave a serving of lavender bodywash.

“Actually, this stuff works better with a sponge…” Carly points out. She holds up her hand sponge, which is a pink ball of webbed fabric.

“I haven’t used one of these before…” you admit.

Carly smiles as she thinks to herself for a moment. “Well… maybe I could help you with that…”

Your nethers twitch again. You half expect her to be playing with you, but you are willing to take the risk. Attempting to maintain your current level of cool and collectedness, you reply, “S… sure! I’d appreciate that!”

Carly fills her sponge with the liquid soap from her bottle, then rubs it to form bubbles. She steps into your shower space and starts running the sponge up and down your back. On the other side of your body, you little friend is wide awake. You angle your body to hide it, just in case it fouls up the moment. Carly covers your back with suds, then lets the shower run over it. She wipes it down and continues to soap up your arm. She turns you around to get to your chest when she notices your raging hard on. She pauses.

You give the girl a meek grin and say, “You know you’re partially to blame for that…”

Carly chuckles and says, “I’ll take that as a compliment…” She continues to lather you with the body wash. Her sponge moves over your shoulder, then your chest. It covers your belly and sides. Once lathered up, she uses her free hand to rinse and rub the soap off. Just as you think she is done giving you a sponge bath, Carly moves her sponge over your belly and onto your rock hard cock. She looks at you with a grin. You almost cum right there.
