Panic

As Erica begins to come down from her orgasm, you realize a few things in rapid succession: you are incredibly aroused, Erica won't be soon, and you're drawing a blank on what to say.

"Ummm," you stammer, "you okay?"

Erica's face turns red as she begins to turn to you, so you panic and say, "Your body is as horny as it capable of being." She instantly takes a sharp intake of breath and begins thrusting her hips into one hand while simultaneously using the other to undo the zipper on her jeans.

Then, she looks back at you and you freeze, seeing the animalistic need buried in her eyes. She moans and throws herself on top of you, straddling you on the couch and needily humping into your dick. You momentarily consider what you've done to her, but within seconds have given in to the situation. You rock your hips back into hers, and kiss her passionately.

Suddenly, she flips you onto you back and removes your pants with a practiced flourish. Before you can even truly register it she's naked and riding you while holding down your torso and nearly screaming with pleasure and need. You reach out and play with her boobs while bucking back into her, and Erica moans louder. Suddenly, you're cumming inside her.

"Shit, I'm sorry," you start to say, before you realize that she's still just as turned on and is now frantically grinding into your limper penis. You're thinking slowly in your post orgasmic haze, but after a few seconds of Erica panting, grinding on you, and fingerling herself you remember exactly what you've done to her, so you say, "Erica, I finished!"

She screams in ecstasy, throwing her hips into you while wrapping her arms tightly against your body. The pleasure in conjunction with the pent-up arousal makes her stay in the throes of orgasm for much longer than she otherwise would have, and by the time she's started to come down you've decided what to do.
