Melanie

Melanie was supposed to be at some school event, but apparently she was playing hookie. His little sister had her eyes closed and was soaking in a bubble bath. She was wearing earbuds, which were connected to her phone, which was in the floor by the tub. As he stood there she shifted and her boobs suddenly popped out of the bubbles.

Barry stared.

He'd seen Melanie around the house bra-less quite often, but he hadn't seen her completely topless in at least ten years. She'd grown a lot since then. A LOT! Her perky boobs glistened with the bubbles that clung to them. Her hard nipples stuck out.

As he watched, she reached up and slowly ran one hand over them, breifly rubbing her nipples. She moaned softly.

Barry suddenly wondered where her other hand was. Her other arm moved slight and she moaned again, leaving no doubt. Melanie was playing with herself under the water.

In 18 years, he'd never once looked at his little sister the way he saw her right now. She wasn't just the slightly annoying little girl he'd always known, she was a fully grown and fully developed woman. A fully developed woman who was naked and masterbating in front of him, unaware that he could see and hear her.

Barry was suddenly very aware of his hard cock. It was beginning to throb.

Well aware of how embarrassing it was to get caught playing with himself, he considered going quietly back to his bedroom and letting her be. But, damn this was hot.

Suddenly she moaned a little louder.

"Oh Barry, you're so big," she suddenly moaned.
