Cassandra teases Michael.

Michael Had never seen a woman masturbate before. Not in real life, at least, and not on purpose. He and Jean had caught each other once or twice, but that wasn’t the same thing, and certainly neither of them stuck around for more than a second or two.

And for a first time viewing experience, Cassandra’s show was quite the introduction. Her long blonde hair barely covered her nipples, despite how her chest heaved with every stroke. She leaned back, stretching her torso and pointing her toes into the water, ballerina-style. Her touch was delicate but persistent, even on her own clit, like a true master. It made Michael wonder how often Cass touched herself, how many people had gotten the chance to see her like this.

All four of the others in the tub had inches closer when Cassandra’s swimsuit had gone over the side of the hot tub. She moaned quietly, giggling really, and aside from the rippling pops of the bubbles, it was the only sound that could be heard. Cassandra held their full attention.

And then Michael felt something touch his chest. He looked down (regretfully) from Cassandra’s perfect body only to find her perfect foot with its perfect toes rubbing gently against his nipple. His face was bright red in no time at all.

“Like what you see?” Cassandra asked, maintaining her Marilyn Monroe-esque breathy pout.

“Y-y-yes,” Michael stammered.

“So does your sister,” Cassandra teased, nodding at Jeannie. “She’s stared at my tits more tonight than you have, and that’s saying a lot.”

Now it was Jeannie’s turn to blush. Unfortunately for her, Cass wasn’t lying. Maybe it was the wine or just the heat, but there was something about Cassandra tonight that had really caught and held her attention.

“You’re both so gorgeous,” Cassandra said. She was still rubbing little circles into her clit, as Jon had dared her to. “And so cute, sitting so close to each other like that.”

Michael glanced at his sister, who was probably less than a foot away. He hadn’t intended to sit so close, but they had both been so hypnotized by Cassandra that it had ended up that way.

“Have you two... ever kissed? Really kissed, not like on the forehead or something? Maybe played doctor?” The look in Cassandra’s eye was rabid. A dog with its eyes set on a bone.

“No, of course not!” Jean spluttered. “Don’t be ridiculous, he’s my little brother!”

“Not so little,” Cassandra said. “Just look what he’s got hidden there under the water and you’ll see he’s gotten nice and big for me.”
