Dry hump her

You move in closer, pulling her in by the close waist as you press against her. The feeling of her thick, warm body against you causes you to gently press your crotch forward, rubbing your hardening cock through your pants against her as she's brought in close.

"Oooh, Jack," she mutters, eagerly responding to your motions.

Lucy shifts her body to better match yours, shoving out her ass. It presses against you, your hard cock rubbing into her ass as her fleshy cheeks embrace your crotch. You moan, sliding forward as you rub against her, her thick cheeks stroking against you. She responds with more eagerness as she feels your cock hardening.

"Ooh, do you like that, Jack?" she asks lustily, as you continue your thrusting, your balls swelling.

Lucy grinds against you, leaving you gasping as you slide against her. You grab either side of her waist, pulling her body against yours with every single thrust, rubbing your sensitive glans against her body. You think about all that's preventing you from plunging into her warm, moist depths: one slight layer of dress fabric, and a single dirty thong. That's all that's preventing you from thrusting into her warmness and fucking her as hard and fast as you want. The thought of this leaves you desperately close to an explosion of ecstasy, so you slow down, grabbing her by the wrist.

"Are you OK?" she asks, turning back to you, confused.

"Yeah, totally," you say, letting out a gasp, before smiling at her. "I like dancing with you."

"I like... "dancing" with you too, Jack," Lucy answers.

Her eyes drop down to your erection, clearly stabbing through your suit pants in an obvious manner. You feel embarrassed for a moment, before you remember she's fully aware how hard she is, as she was just left thrusting against it. You smile at her, blushing.
