Sit on her, just below her butt?

Carl climbed on the bed, causing Steffi to bounce up and down a bit whilst he stepped over her. He kneeled and sat over Steffi's butt. He tried to ignore the growing hardness in his crotch area.

"Where should I start?" Carl asked.
"Do my shoulders first, then go down to my lower back. That's where I'm really sore. Then if you want you can do my legs." Steffi responded. She didn't half ask for much!

Carl started rubbing her shoulders. He felt a lot of knots there and started to work her really hard, but it was difficult through her shirt and bra. Every so often Steffi would move her shoulder as if he was itching her until finally she spoke up.

"Wow, Carl could you be a little less rough please?"
