Yep! She's a needy cockslut.

Blinking her orgasm-unfocused eyes Cassie realized what was happening - Steve was climbing on top of her, huge cock out and just inches away from her dripping pussy, separated only by a skirt and thin pair of panties. Was she going to allow this? She'd recalled thinking to herself I'll never let that guy fuck me just a couple days ago, and then saying it to his face after he came on her tits (unconvincing in context maybe). And now...

"Fuck yes give me that cock."

"Oh? Maybe I should make you beg. You made Sofia eat you out, you just fingered yourself in front of me while I sucked your toes you freak and now you still want cock?"

I'm not gonna let him play games. Even if I need his cock.

Cassie pulled up her skirt and slipped her panties down.

"Yes, I need you now. I'm fucking begging for your hard fat cock in my tight pussy. Now now now or I might just have to walk out of here and fuck the first man I see who isn't gonna tease me."

"Rich coming from you," Steve snorted, but he wasted no time pulling her legs wide apart and then plunging himself into her.

"UNGH! Jesus how are you so big!?"

"Good thing you're lubed up enough for me."

He thrust in and out of her fast, not pausing or letting her get her bearings. He was fully focused on his own pleasure, and why not after all the tantalizing teasing she'd put him through before? One of her tits bounced free from her tube top with the **** of his thrusting. He leaned over to giver her nipple a hard suck, then a bite.

"I'll get around to titfucking you soon enough, but your pussy feels so damn good right now. Shit, are you a virgin?"

"N-no. But it's been a while."

"Lucky to have me."

Steve's focus drifted off of conversation. He was sweaty, grunting, animalistic. He buries his shaft deep with each thrust, and Cassie felt it fill her almost unbearably. She was tight. But pleasure, the pleasure of being taken and giving pleasure to her admirer if nothing else, overrode discomfort.

"Cum in me."

"Hell yeah. You're on the pill right?"

"Yes," Cassie lied. She just wanted his juices in her, pumping in, then dripping out of her cunt. She wanted to be possessed, marked. She wanted, in that moment, to be the slut who spends her whole day reminded of her conquest by the seed trickling out of her and staining her panties.

Steve didn't disappoint. He thrust in, extra deep, and shy physically felt his cock convulse as he grunted and filled her. Pulse followed pulse in her depths and the sheer erotic thrill made her cum once more. Her pussy squeezed a few more drops from Steve before he withdrew.

Cassie was exhausted, limp and sweaty on the couch. Steve stood up and put his clothes back on. Relieved of his tension but also filled with a cockiness she'd never seen in him. She finally tuned in to what he was saying

"I'll be back in a week. Be sure to watch the study video I'll send you tonight before then. Remember, exam time is almost here."

There was a smarmy edge to his voice, but in that moment Cassie only thought of the blissful animal fuck he'd just given her.
