Yes

Despite a sudden protest from the back of his mind that this was wrong, Barry couldn't help himself. He stripped off his basketball shorts and stepped into the warm, bubby water.

When they were kids this tub had seemed huge. And while it was a big tub, it barely had room for two adult sized people. He had to slid a leg around each side of his sister's body to finally get to a seated position.

"Doesn't that feel good?" she asked, removing her hands from her eyes.

"Actually, yes," he admitted. "I don't think I've taken a bath since we used to take them together."

"I take a bath at least once or twice a week," Melanie told him. She looked back at him and smiled innocently. "Maybe you should join me more often. A good warm bubble bath releases a lot of stress and tension."

"Not sure mom and dad would approve of us bathing together," he told her.

"Don't tell them then," she said.

Suddenly Melanie pushed her body backwards and she scooted against him. Her ass was pressed against his balls, and his erection ran right up her bare back. She looked at him, wide eyed.

"Barry, I am your sister!" she said in shock. "You shouldn't be hard thinking about your sister! What kind of pervert are you?"

"Uh-uh...I.."

"I really hope you're the kind that will do something about it!"
