"Ohhh, Doug! I feel so funny. My cunt is itching something awful!"

"It feels good!"

She clung to him, rocking her hips to match his movements, then shifting her rhythm so that they moved differently. Both of them were lost completely in the pleasure of this new thing they'd found. Fucking! Robyn could hardly believe it had happened so quickly. She was fucking!

"Uhhhh, it's going into me so deep it scares me!" she cried.

"I'm not hurting you, am I?"

"No," Robyn blurted. "No, it doesn't hurt."

"It feels wonderful to me," Doug groaned. "I never guessed it would be so tight and hot."

"Slick too! Ohhh, it's so juicy and nice when we move around like this!" Robyn's hips lurched as she humped her back down into the bed. Doug fucked her deeply and slowly. When his lips brushed her again, she opened her mouth to be kissed.

"Ummmmm," she moaned through her nose. To be kissed and fucked at the same time was something so exquisite that Robyn could hardly believe it. She'd never imagined that there could be such pleasure!

"Ohhh, Robyn! Ohhhhh, shit, I think I'm gonna come."

At first the words meant nothing to her. She was too lost in her own itchy excitement, lost in the feverish need to rub her tickling pussy against the hardness of her brother's cock. When she caught the meaning of what he'd said, she tensed and shook her head hard.

"You really do have to stop now, Doug! Do you hear me? Doug!"

Doug kept rocking and thrusting and kissing her neck and chest. She beat upon his back and shoulders. Her heels dug against the backs of his thighs.
