Talk Emily though it

"That feels really nice, Emily," you tell her. "Do you have a lot of practise pulling on boy's cocks?"

Emily blushed. "N-no," she stammers. "I'm not that kind of girl." she says defensively, standing straighter and pulling her hand away from her reddened snatch. She seems then to consider what you said. "You really like it?"

"Yeah," you say, panting. "Are you sure you don't have practise jacking boys off? It's okay, you can tell me," you tease. Whatever experience the Emily you remembered might have had, you knew full well that this was her first hand-job... possibly the first of many.

Emily blushed. "I'm not really trying to jack you off, John. I'm trying to make sure your fully erect penis is nice and clean." From how she was blushing and avoiding your eye contact, you weren't sure that even she believed it.

"And I really haven't jacked off any other boys before either," Emily continued. "Though I've thought about it a lot. I like the idea of holding and stroking a boy's erect penis," she says, breathing a bit heavily.

"How does the idea of holding and pulling on boy's cocks make you feel?" you decide to ask, panting.

Emily moans. "Very sexy," she says. "I like the idea of men being erect for me, and making them ejaculate."

"Where do you like to think of them ejaculating?" you pant.

"All over me," she says. "From my collar bones down to my pubes."

"Oh... kay!" you grunt, as you are pushed over the edge by Emily's 'cleaning'.

A thick rope of cum erupts from your cock, landing on Emily's left neck and shoulder. Emily squeaks excitedly with surprise, pulling your cock to the right just in time for you spray a second jet of semen against the inside of her right breast. You moan loudly.

"Ah! John," Emily shouts. "You're cumming all over me!" She plunges a hand down to her pussy and starts rubbing frantically.

You spray another thick jet over Emily's belly button, catching her left arm as well. You moan, and feel yourself run out of pressure as your semen pools into Emily's hand. She is still absently stroking your cock, but her attention is more on her left hand, which she is using to furiously flick her bean.

You look to Emily. She is looking back at you with a mixture of shock and abject lust as she approaches orgasm.
