"It would help if one of the girls undressed..."

"Ah, sure," you say, "I guess the best way for me to get hard would be to see one of these girls undressing."

"Oh!" Diana said, surprised, "I thought you'd just touch yourself."

You look over the girls, taking in the blonde girl with full breasts under her checkered blouse, the little nervous looking redhead, and the skinny girl with long black hair and a mischievous smile. "What do you think? Any of you want to undress for me?"

The girls looked at each other and laughed a little awkwardly. Then they looked up at Diana, wondering what they should do.

"Well, why not?" Asked Diana with a shrug, "which girl would get you the hardest?"
