Waiting

Jack closed his door and sat down on his bed. Was it weird knowing that Beth knew he was gonna be masturbating in like 5 minutes? Yes and no. He still wasn't as comfortable with the situation as Beth was, but her knowing was kinda hot.

The anticipation of waiting for Beth made his dick really hard. He started touching it over his pants, he couldn't help himself. Just then he heard a quick knock at the door, Beth entered without waiting to be invited in.

"Couldn't wait huh," she said smirking. Jacks hand was still on his dick.

Jack quickly lifted his hand, slightly embarrassed. At this point he really shouldn't feel embarrassed about anything. "Yeah hehe, " he said nervously.

Beth stared at his growing dick for a second and then looked up at him, "Well, I'll um...let you get to it," she said tossing her panties into Jack's lap right on top of his dick. "See you at dinner," she said smiling as she closed the door behind her.

Jack got up quickly and locked the door. He can't disappoint his sister.
