Fuck her now!

You play with her a little longer and then move one hand from her breast to her back, pushing her forward. You push her hips back using the hand at her pussy until she slides her rear past your hard member. You switch from her pussy to your penis and guide it into her. She turns around realizing your intention. You push her forward so she has to put her hands out in a splash. She's now on her hands and knees. You sit up and go back to her slit with your cock.

"What do you think you're..." She starts to ask but is interrupted by you pressing the tip of your cock into her.

"Pleasuring you and relieving myself." You push into her further without waiting for a response.

"John..." Courtney begins to object but you easily push the rest of the your member into her. "...Ugfh"

"You're pussy is so welcoming Courtney, I just slid right in." You place your hands on her soapy hips. Feeling her soft, slippery skin, you begin a slow rhythm into her. "This is a much better place for a hard cock than squished between us." You increase your pace to emphasize that point.

"You're bigger than Ty." Courtney states temporarily lost in the motions. "but..."

"Shh, we've been dancing around this for a while. Just enjoy it Courtney." You thrust against her harder, weakening her arm support. She struggles to keep her head above the water. You keep your pace to keep her struggling but above water.

"I'm going to cum inside you." You tease her, she tries looking at you but goes under the water first. She quickly rights herself just before you increase your pace to keep her quiet. Soon after you empty yourself into her. You pull out once you go limp and help her sit up and back into the tub.

"What was that?" Courtney asks harshly.

"I just wanted inside you, I got a little wild."

"You didn't have to **** me, I would have fucked you if you asked."

"Did you enjoy it?"

"Actually, it was kinda exciting..."

"Did you want it?"

"Yeah, but not like..."

"So you are okay with it?"

"I guess, it was hot, even though I didn't get off." Courtney answers, relieving you a bit. "Can you **** me again? Only this time make me cum."

Taken a little aback you start thinking of ways to surprise and excite her.
