My mom's boyfriend used to wait for me to get out of the shower when I was 4 or 5 years old. He'd wait in the master bedroom for me to come out of the bathroom, then said we'd play the naked towel game. He'd have me jump up and down on the bed, naked. I wasn't allowed to get into the towel until I'd jumped enough for him. Eventually he'd hold the towel out and I'd have to jump into his arms and he'd rub me dry. It wasn't fun; I can't imagine what he got out of it.
