Intercourse, with an impossible reversal.

Rosalind used the thick railing to support herself as she rode the doctor’s dick. And she couldn’t handle it. Her G-spot kept getting stroked in the exact way that made her whimper, so poor Rosalind could barely move as the hunk underneath her pussy tried to adjust.

It only made matters worse that when she looked down, she saw Eliot biting his lip, looking at her stupendously-wet vagina, blushing like a schoolboy.

When the research partners thought it couldn’t get any more exciting—or embarrassing—a screeching sound tore through the woods, prompting Rosalind (and Eliot) to let out a girlish scream. He looked up at the brunette like he heard a ghost, but more like he’d humiliated himself, and said to her as he tried to cover up, “Ros, I, uh, think maybe we should grab, grab a blanket.”

The brunette nodded her tomato-red face in agreement, and moaned as she reached for the sheet covering the backseat. There was a quiet ‘squelch’ when Eliot’s dick slid out of her pussy. She rummaged into the open window to grab some modesty, and turned around expecting to top the sexy, blushing scientist some more.

But the bespectacled co-ed found herself bowled over as the stud pinned her shoulders to the truck bed; even stealing the bedspread from her as she fell.

She felt her body get pressed into the cushioned metal as the sheet fell over the pair. It was easy to forget sometimes that bashful, blushing, innocent Eliot had muscles. Or that he could ogle people like that. She flushed somehow redder.

With the blanket for cover, it seemed like Dr.Browning was a completely different person: For the first time in their relationship, he was eyeing Rosalind’s half-naked body like a fine cut of meat. A little peep left her mouth, and she went totally scarlet as Eliot spread her thighs; licking his lips at the sight of her dribbling vagina. “My my, Ros… are you really that excited right now? It’s like you’re begging for me to tease you, you little pervert.”

“Fuck me.”

“That’s not quite right, Ros.” The scientist said, tickling her inner thighs with his finger to watch her squirm, “You’ll need to be more polite than that. If you can’t be demanding, then you’ll have to be courteous. Try again.”

“P-please… fuck me.”

“That’s better.”

The girl whimpered and shook as Eliot entered her wet folds again— she was already too aroused to do anything but take it as her fantasy became reality. She moaned as fireworks mingled with the intense embarrassment in her head, and found herself cruising towards cloud nine as the hunk took things slow and sensual.

The both of them had forgotten the screech in the midst of their fucking.
