"Okay, Sis," Eddy grinned, grabbing her cunt and kissing her on the lips Donna had smeared so thick with pussy-juices. "We don't get out of your bed."

Still lying close to sham, Donna watched the naked boy and girl curl together, slip cock into cent, and start hunching slow. She enjoyed seeing their perfect young bodies do such sensual movements.

"Well, all right. Go ahead and fuck. I'll try to keep your mother and father from catching you. Just don't hump around so loud I can't," she said.

"We'll fuck quiet, Aunt Donna," Suzy giggled.

Donna reluctantly slid from the bed and stood beside it, pulling her clothes on as she watched the graceful fucking. She started wondering how Suzy had got to be such a good cock-sucker.

"Suzy, is Eddy's prick the only one you practiced sucking?" she asked.

"Mmmm, I sucked one other prick, Aunt Donna," Suzy said. "A bigger one."

"Whose?" Donna asked, puzzling when Suzy blushed and would not say.

"Uh… forget it a while, Aunt Donna, please," Suzy pleaded softly.

"Well, okay," Donna said, more curious now. "When will you tell me?"

"I might show you, instead of tell you," the little brunette suggested.

"Oh, shut up, Sis," Eddy said. "If you're gonna fuck, fuck."

"Well, fuck!" Suzy giggled, throwing her pussy up on his prick, gurgling when he kissed her deep and began knocking her ass down into the mattress.

Donna turned out the light and left, closing the bedroom door. In the kitchen, she started a pot of coffee for her sister Pam and Pam's husband. Her cunt dripped when she remembered the good orgasms she'd just had.

"God, I'll love fucking Eddy. With Suzy screwing him, too, she'd keep our secret," Donna mused. "I like having my sister and John living with me."
