His older sister, Rhonda
From Torg Adventure
The door opened, and Ben's sister, Rhonda, stood in the door. She should have been at college, but Ben vaguely remembered she was coming home this weekend. She closed the door behind her. She was wearing a red tee shirt with her favorite coffee shop's logo on it. She also had hip-hugger jeans on. Her big tits stretched the tee shirt so the logo was distorted.
"Hey, Big Boy. Is that for me?" she asked with a steamy quality to her voice.
Ben freaked out. As often as he'd fantasized about Rhonda, her come-on really squicked him out when it was in his face. "Rhonda is not interested in me sexually," he said under his breath, as he put a towel around his waist. He still bulged out in front.
She got a weird look on her face, and then said, "Oh, excuse me. I didn't mean to barge in on you." She ducked out the door quickly.
Ben realized he was going to have to be very careful how he phrased his wishes. Too vague and anything could happen. He pondered his options for a minute. His thoughts turned to the voluptuous MILF next door, Mrs. Rayburn.
"I want to fuck Mrs. Rayburn and have no one say anything about it."
What next?
