Show off that hot body, sis

"Show off that hot body, sis." He releases his grip on the bag.

Tanya, shocking both herself and Drew, slides the dress up and over her head. She gives her brother a full view of her teen body. She twists and turns like she's modeling in front of a camera, showing off every curve.

Once he's able to lift his jaw off the floor all he can manage is "holy shit." he steps back so he can get a full view. Tanya uses the extra space to bend over and show off her ass. "You are an exhibitionist."

"I am an exhibitionist," Tanya hears herself say and realizes that, yes, she totally is. She likes revealing her body to people.

Drew grins. His hands move down to his pants restraining his hard cock. He unbuttons the top of the fly and zips it down.

"Wh-what are you doing?" Tanya asks unable to stop showing herself off.

"I want to show off, too. Do you want to see?"

Never in her life did she want to see her brother's cock. Yet, at this moment, all she can say is "yes."

Drew drops his pants and frees his cock. Tanya tries not to look at it as Drew starts to stroke while watching her continue to model her body. "I guess being a horndog is genetic," he says, "why don't you sit on the stairs and show me how horned up you get showing off? Show me how you masturbate, sis."

She tries to shake her head "no" but instead her body moves to the stairs. She can't deny what he's saying. The longer he stares at her body the more turned on she gets. She feels ashamed but can't help herself. Tanya spreads her legs and starts to move her fingers between her labia. She moans as she matches the rhythm of Drew's stroking.

"This is so wrong," Tanya moans as she squirms on the stairs.

"It's, unf, only wrong if we touch. There's nothing, mmhmm, wrong with solo pleasure in front of family."

It takes a moment but Tanya finds herself thinking his argument is completely logical. There's nothing wrong with solo pleasure in front of family as long as they aren't touching. Of course. Her inhibitions about masturbating in front of Drew fading, she tosses her head back and allows herself to completely enjoy the moment. Her free hand slides up her body cupping a breast. She takes a nipple between a finger and squeezes gently. More for the show than for receiving actual pleasure from it.

"Fuck, you're so sexy." Drew groans. He feels his balls clenching. He's ready to finally release the load he spent all morning building up. But where?
