"Ohhhhh, Goddamn!"

"Feel good?" Doug asked.

"Can't talk," Robyn groaned, still bucking. For a long while she squirmed and trembled until at last the spasms had passed and she sagged, exhausted and panting next to her brother's warmth. They were both cummy and the sharp smell made her feel strange. The shock of what had happened was starting to soak into her consciousness.

"Don't cry, for God's sake," Doug said, shoving the top of his pajamas across her belly. "Why don't you take a nice warm bath."

Robyn sat up, her eyes waxy and red. "What we did! Ohhh, Doug, I'm so ashamed! We fucked. We're brother and sister and we fucked!"

"You don't have to start bawling!" Doug said, looking round nervously. "Mom and Dad don't ever have to find out. If you don't go blabbing."

Robyn whimpered, burying her face in her hands.

"Hey, calm down. You're not hurt are you?"

Sniffling noisily, Robyn looked down at her cunt. Her pussy was swollen so that her flesh bloomed out like some strange flower. She touched the tender, fuck-rubbed places.

"…I guess not. It's kind of sore."

"I'm sore too," Doug said. "You were really squeezing me at the last."

A shiver went through Robyn's body. Her cunt was still throbbing with the afterglow of the pleasure she'd felt. She got up and walked unsteadily to the door and down the hall. She was still sniffling, but starting to calm down a bit now. She ran herself a tub of hot water, quickly soaping the drying cum from her belly. Her nipples were sore from where her brother had kissed them.

"I can't hardly believe it," she kept mumbling. "Doug fucked me. I fucked Doug. We fucked!"

To forget what had happened, Robyn took the money Doug gave her and hurried downtown to buy the purple bikini she'd wanted so badly.
