Play with Sarah.

You drop the scrub and begin rubbing between Sarah's legs. She doesn't protest. Instead she starts moving her hips to grind against your hand.

You move your free hand up to squeeze one of her breasts as you slide a finger inside her and find her clit. She gasps and then begins to moan as you bring her closer to climax. She tenses and then relaxes, collapsing back against you breathing heavily.

A few moments later, Tanya lets herself back into the bathroom. She helps Sarah out of the tub and wraps her in a big fluffy pink towel. She then holds out an identical towel for you.

"Come on." Sarah encourages you.

"Can I have some privacy?" You ask hopefully. It's bad enough that Tanya would be seeing you naked but you also have a rock hard boner right now.

"I think he's embarrassed because he has a stiffy." Sarah teases.

"Is that all?" Tanya reaches for your hand and pulls you up and out of the tub. "Oh wow. You are excited." She comments, seeing you dick standing straight out from your body. "I'm not going to be able to put your diaper on with that."

"Diaper?" you ask.

"You said you'd wear my clothes." Sarah says. "I don't own any panties."

"I'll just wear my own underpants." You say.

"Sorry." Tanya says. "I put all your clothes in the washing machine."

"So... What are we going to do about this?" She playfully caresses your erection, not helping at all.

"You could always make him cum." Tanya suggests. "It'll go away after that."

Sarah smiles at you. "Would you like that?"
