"More!" she demanded. "I want more of iiitttttt!"

"Greedy bitch!" muttered Cat. But she gave the girl what she demanded.

She began thrusting her hips forward to drive the dildo up into the tight little hole between the girl's legs.

Susan got the idea. She began thrusting back, as if she were driving her hips down to meet on incoming cock. Together, the women used the dildo to the best possible advantage.

Every nerve in Susan's body sang with delight. She was flushed, her breathing hurried and her cunt totally filled. When she felt Cat's groping finger hunting for her clit, she returned the favor. Together, they diddled with each other's go buttons until Cat shrieked. She came with a huge heave of her hips.

This drove the dildo all the way up to Susan's cervix. And the finger on her clitoris was definitely not going away. It continued to stroke and fondle and stimulate her until she could feel the crouching beast of orgasm in her own loins. Her cunt began to flow faster. Her tits threatened to explode.

Then her entire world blew up. The combination of the rubber cock up her twat, the finger on her clit, the pressing against her nipples, all conspired to give her a tumultuous orgasm.

She fluttered on the winds of her climax until she came down from her sexual high. For long moments, she wasn't quite sure what had happened, where she was.

Then it all fit together.

She'd just let her father's girlfriend stuff a dildo up her cunt. And Cat had the other end of the double-ended dong in her own twat. And they'd made it together.

Susan shuddered at what she'd done. It wasn't right, making love with another woman!

Again, as if reading her mind, Cat said, "It was good, wasn't it? So what could be wrong with it?"
