Fights, then melts...

She tries to fight back for a few moments, pushing and beating at your shoulder while trying to get your exploring tongue out of her mouth, but she's obviously not putting herself whole-heartedly to it and her attempts quickly grow weaker.

Latching your hand to one of her big breasts, you can feel her nipple press against your palm through the tight top, and a moan escapes her lips as you tweak it playfully. Knowing that you have her, you don't waste any more time and brusquely free her from the towel and pull her thong aside. She gasps in surprise as you press your hand against her bared crotch, your fingers easily sliding along her glistening wet crack.

Searching the area just above her tight entrance, soaking your fingers in the process, you find her clit and start massaging it roughly, drawing a loud groan of both fear and pleasure from the girl. You keep rubbing her soft spot for a little while, feeling her resistance cease as her ****-inbued excitement starts to take over, before you gently press first one, and then two fingers into her hot tightness.

"What... What did you give me...?!" she pants and gasps into your mouth, squirming around in your arms while you fuck her tight pussy with your fingers.

"Just a few pills of Spanish fly!" You tell her throatily while frantically grinding your lips against hers and your hand against her pussy, seeing her eyes grow even wider. "Don't worry, it's just an enhancer! When it's out of your system, you'll still know you wanted this!"

"N... No...!" She tries to object, even as her lips and tongue start to kiss you back while she grinds her crotch against your probing fingers.
