FUCK! She's so hot.. he thought, as he starred through the cracked bathroom door. The steam was filling a lot of the room, but there was still enough visibility to see her body. The body of his step-sister.

For weeks since the wedding she'd pranced around the house in barely enough clothes to be decent. A white t-shirt and panties were the usual attire, but sometimes that was too much. Several times it had been a crop top, sans bra, and panties, so that if she lifted her arms juuust enough, the slightest amount of breast would be exposed. Other times it was just a tank top/panties. Once she'd just walked around the house all day in her undies!

And did she care? Hell no! It was summer break for him, and she'd just graduated. His dad and her new wife were away at work all day, just leaving him and his new, hot step-sister to torment him all day. And torment him she did. She could tell the effect she had on him. The way he went all flush when she's stretch just a fewww seconds too long. Or when she dropped something and slowwwly bent over to pick it up. Torture. Pure. Torture.

And now here he was. Cock in hand, peering through the doorway, finally seeing her perfect tits. Her shaved pussy. Everything. The water just added to it all. His member felt hot and willing in his hand as he rubbed it slowly. His eyes went down her body, taking her all in. Then back up to her face. What? SHIT! She was looking right at him!

"What the FUCK, Nick?!"

Hey DPP. This is my first time posting here, I hope this prompt is ok. I'm looking for someone to help me play this out. I don't know how fast these tend to move as far as responses, but I'll do my best to keep up so we're not bored. ;)
