Keep it about her.

While playing with Courtney's clit and nipple you say, "Up for round two?"

"Oh my yes. Keep doing what your doing." She says and grinds against your cock some more. You keep playing with her and she keeps rubbing up against you and playing with her body too. She squirms around enjoying what you're doing to her, rubbing up against you enough to keep you erect but unsatisfied. This goes on for a little bit until she arches her back against you and starts kissing your neck. You can tell she's getting close. You pick up the pace, pinching her nipples and rolling her clit. She strains against you and finally cums again letting out a moan and relaxes back against you. Resting her head against your shoulder. Courtney starts kissing you on the lips for the first time, then whispers in your ear, "It's been a long time since someone focused on me." She wriggles against you, letting the water slosh around. Your rock hard cock sliding between your bodies.

"Aww, that's probably hurting by now." She reaches around and grabs it with her hand and starts stroking it. "Poor guy, have I been neglecting you?"

"You needed it more than me."

"How thoughtful of you." She sits up a little and grabs her glass of wine, downs it and turns to you. "Up for round 3?" She sets the glass back down, with a wide grin.

"Sure, what did you have in mind?"
