Ask her to turn around

"Courtney" you ask "can you turn around? It will be... more comfortable"

She giggles in response "Someone wants to see my tits. I think you deserve that much." She gets up, letting you to see her pussy for few seconds, turns around and sits facing you, sitting high enough to let you admire her tits. Unfortunately that came for a price, as now she doesn't sit as close as before. "Do you like them? " Courtney asks as she caresses her breasts seductively.

"You are gorgeous." You answer, failing to even pretend that you aren't just staring at her tits.

"I don't think I'm really helping you relax? " Courtney giggles once again, "pressing my back at your member, letting you group my intimate parts and now demonstrating my goods. You must be dreaming to push me down and fuck my brains out for all this cock-teasing?"

"Uhmmm" You answer "Don't worry. I can control myself."

"I'm not worrying!" Courtney laughs "I'm having fun, its amusing to me, driving you mad." Suddenly her right arm goes underwater and you feel her palm firmly grab your member.

"Auuuu..." You moan, failing to say anything more complex, you are so close that you can barely think, but with the last bits of willpower you do ask "What are you doing?"

"Shut up!" Courtney seductively smiles "I'm not gonna let my friend fuck me, but I can't let you stay like that, either. So relax, enjoy the view and imagine how you would pound me in whatever hole you want." Her hand starts to jerk you off better than you would do it yourself.

She continues to pound your dick with one hand, erotically caressing her tits with another and even moaning softly to herself. All this quickly forces you to have the best orgasm you've ever had.

"Wow!" Is the only world you say while Courtney milks your cock for the last drops of cum.
