He wants to watch her play

"I want to watch you cum again...no camera, just you and me in your room. No vibrator either."

"Well, it could have been worse, he could have asked to fuck her," she thought as she crossed her arms under her sizable chest, "What assurances do I have that you'll delete the video?"

Sean eyed her suspiciously and shrugged, "You don't really, but when I come out of my room I will be wearing a t-shirt and gym shorts with no pockets. So, you'll know I don't have my phone to record more." He looked her in the eyes, "When we're done in your room I'll let you come back with me into my room and you can have full access to my phone to delete the video yourself. OK?"

Ashley sighed, "I guess I don't really have a choice," she turned and walked back up the stairs, stopping halfway up, "Well...are you coming or what?"

Sean quickly changed into his gym shorts, removing his underwear, and freshening up his deoderant before unlocking the chain-lock, then locking the deadbolt with his key. He climbed the stairs with a grin on his face and followed his sexy step-sister up to her room.

When they were both in her room, she closed and locked the door, and then sat on the edge of her bed and looked at the floor. Sean sat next to her, and Ashley quickly moved away from him. "Hey! Ash, what's wrong? We had an arrangement here!" His voice took on a threatening tone and he looked to her, confused.

Ashley looked up to him, her eyes wide and bluer than he had ever seen them before, she seemed anxious, "Listen... "I've never done stuff like this in front of a boy before." She was blushing a deeper red than a tomato, "I'm not ashamed to say that I'm a virgin, but when you saw me cum earlier, twice... that was the first time anyone besides me has seen me cum."

Sean instantly felt bad, and almost pulled out of his deal with her simply for that reason. He even opened his mouth to say so when Ashley continued, "But you have that video and I don't want that to be the one thing I'm remembered for, so I'll do this for you, OK?"

He nodded and smiled, although this was a meeker smile than before, "OK." He stood up and looked around, "Do you mind if I sit in your computer chair?" He rolled it over near the end of her bed and sat down, his cock growing harder in his shorts, "How's this?"

She nodded and began to disrobe again. When Ashley removed her shirt, and her hair had settled down from the action, she found Sean's bright blue eyes looking not at her breasts, but looking at her face, "What?" She asked, wondering what was wrong.

"Nothing," he said, and cleared his throat, "It's just that you are really beautiful...did you know that?" He smiled warmly and then allowed his eyes to flick down to her breasts, where her blush had already deepened and spread across her beautifully inked chest.

When she lifted her hips to remove her yoga pants, she found Sean looking her all over again, hungrily, as though she were something to be desired. She'd never been looked at like that before. Always in school she had dressed to de-emphasize her body, ashamed of her breasts and ass. But Sean was here and it seemed like he liked looking at her. She felt herself grow wet at the thought.
