She lets you take her virginity

"Take...me...John..." she softly moans as you slide your dick up and down her tight pussy lips, her back arching as you suck on her tits and slowly sink it into her.

"Are you sure Katie?" you ask her as you begin to thrust into her, tearing apart her hymen as she throws her head back.

"FUCK...YES...OHGOD...fuck me..." she hisses as you start to fuck her tight pussy, her no-longer-virginal walls clinging to your dick as you plunge it into her, her eyes starting to roll back in her head.

"UH...YES...YES...YES..." she moans as she slams her hips into yours and cums all over your dick, her walls wrapping it up tightly as you keep on thrusting into her.

"UH...OHGOD..." she purrs as she goes limp, her long legs wrapping around you as you start to quicken your thrusting into her, the thought of pulling out of her not even crossing your mind.

Besides, you didn't think there was any doubt in your mind that that's what she wanted you to do, anyway.
