You want her to finger herself.

"Well, my first idea is for you to keep fingering yourself while I watch you." you say, reaching down to untie your shoes.

"Mmm. I like that idea," Shanice says. She lies back and pushes her pussy lips apart for you to just barely peek. She pushes her fingers into her and starts frigging herself with short, slow movements. Her breath deepens, and you expect her to climax, but she stops herself just before it happens, and moves her attention to her nipples. She seems to be trying to calm herself down at this point.

"Do you always stop at that moment?" you ask, trying to pull your pants off while they're bunched up around your ankles.

"What? Oh. Yeah, I always stop at that point or earlier. I start feeling like there's something beyond that, but I'm a litle scared. I don't really know what'll happen if I push myself and lose control. I can masturbate for hours like this."

You finally get one pant leg off. "So... have you ever talked to anybody about... orgasms... and masturbation... and what feels good?"

"Nope! It's all been self-taught. Experience and experiments. I didn't know any girls who wanted to be around me long enough to get close. Besides, what else is there to learn? I know what I like, and it feels good."

You peel off your shirt and look at her, letting this sink in. Sex for her has been boys ejaculating and her receiving affection, similar to a cat being petted. Pleasurable, but no more than that. Shanice... despite being easy... has never... achieved... orgasm.

Wow.

Fully nude now, you smile at her. "Well Shanice, I think you'll be in for two new experiences tonight. Now, do you want it gentle or rough?
