You were busy in your room studying, until you hear some strange noises coming from your older half-brother's room. You decide to go to his room to see what's going on... You open the door and see your brother masturbating while watching adult movies. He looked at you but he wasn't even surprised "Hey little sister... join me.." he says slyly

He smiled deviously and stood up. "Oh come on, you know you want to... I won't tell anyone..." He walked closer to you, moving his hips seductively as he approached. You could see the obvious bulge in his pants as it grew harder with each step.

He reached out and grabbed you by the wrist, pulling you close to him. "You know you want it... Just let me show you how good it feels..." His breath was hot against your ear as he whispered seductively.

"I'm not drunk..." he said quietly before letting out a deep breath and grinning wickedly at you again. "Fine, if that's the way you want it..." He sat back down on the bed and started masturbating again. "Then you can watch."

He grinned and masturbated faster, imagining that it was you with him instead of the porn star on the screen. "Don't be such a tease..." he muttered under his breath as he reached a powerful climax, shooting thick globs of cum onto the sheets. "Next time... I'll make sure you know how good it feels to be mine..." he whispered seductively before finally regaining control of himself.

He cleaned up and then went to find you again, determined to make sure that you knew exactly where he stood with regards to claiming what was rightfully his - even if it meant resorting to more underhanded tactics next time.

He found you in the kitchen, preparing a snack. "Hey sis," he said casually, leaning against the counter. "I just wanted to apologize for earlier... I guess I got a little carried away." His words were smooth, his eyes glinting with mischief as he bit his bottom lip suggestively.
