You take them off, of course

"Good decision," Vanessa mouths to you as you peel her panties off of her and she slides your pants off, quickly removing your underwear as she lowers her pussy down onto your dick.

"UH...YEAH...fuck me John..." she moans as you grab her hips and move her up and down on your dick, Vanessa beginning to bounce herself on it after a few minutes.

"Damn you're tight Vanessa," you whisper to her as you fill her pussy with more and more of your dick, wanting nothing more than to cum inside of her right here at this party with all these people watching.

"FUCK...ME..." she moans, throwing her head back as she lowers herself onto your dick one last time and leaves it there as you start to violently thrust into her, her walls starting to cling to it as you bury yourself inside of her.

"You're gonna cum for me, aren't you Vanessa?" you tease her as you grab her hips and slam her down onto your dick once more, Vanessa suffering an earth-shattering orgasm as she cums all over your dick, her eyes rolling back in her head as she pushes her hips into yours.

Knowing you couldn't hold out any longer, and quite sure that Vanessa had no problem letting you finish inside of her, you thrust a few times deep inside of her and grabbed her hips, slamming them into yours as your cum came rushing out from your balls.
