Experimenting (masturbating)

After filling a couple pages of her journal with thorough notes and measurements, Emily is buzzing with excitement. She resists the urge to tell someone about her breakthrough, choosing to at least wait until she can get to the lab tomorrow to run some tests. She wonders if she should even try to keep it hidden from Chris, her lab tech. A smile crosses her lips as she imagines his reaction to the news that a 'cure' has been found, but that it won't work on men.

She dedicates herself to figuring out what she can with the time she has available. She puts on a pot of coffee and heats up some toast, eating a quick breakfast while she jots down potential experiments. As she goes back over the list she's a little embarrassed to see how sexual they are:

Erection test, stimulation, ejaculation?, sensitivity, growth rate, refractory period?, penetration testing...

"Well it's not like I can measure things like hormones or sperm count without equipment." She mutters as an excuse.

Once she's done eating she gets down to business. She isn't sure if increased libido is a side effect, or if the idea of having her own dick to play with just turns her on, but she finds herself getting an erection before she's even made it back to the bedroom.

"Hey little buddy, you wanna play?" She asks her penis, squishing it gently with her fingertips to gauge its firmness. Already she's harder than last night, and she can feel herself growing harder still, pushing her fingers apart as her dick swells.

"Whoa, that feels kind of nice." Emily says, laying down on the bed and gently stroking the head of her cock as it grows fully erect. It's a peculiar sensation to get accustomed to, the tumescence and heightened sensitivity is not unlike what happens when one of her nipples gets hard, but this feeling is so much more palpable.

There's a stiffness to it, almost like a muscle flexing involuntarily, and along with that comes a pressure, a fullness. Her cock flushes and swells, and she begins to feel a yearning to push back against it. She wraps her hand around her slender member and holds it for a moment, savoring the way her grip envelops her needy erection with a satisfying pressure.

"Mm, I'm starting to understand why guys were so obsessed with these." Emily says, beginning to gently stroke her dick up and down. "It's hard not to want to play with it." She tries to take it slow, but can't resist the urge to pump faster and harder. Before she can stop herself she's having an orgasm.

"Oh fuck..." She groans as her dick starts twitching in her hand. She can even feel the pulsing orgasm deep down in her pussy. All of a sudden hot bursts of fluid begin to shoot out of her dick, soaking her belly and running onto the sheets. She hates the mess, but finds the feeling of ejaculating to be deeply satisfying.

As she comes down from her climax she's shocked at just how much fluid got on the bed. She laughs a little as she takes stock of the situation. "Wasn't expecting so much to come out." She mutters as she peels herself off the sheets. "I'll have to get used to that."

Another surprise is that despite her recent ejaculation, her cock remains rock hard and receptive to touch. "Well that's convenient." She muses. "Glad I won't need to worry about going soft every time I cum."

Emily takes a quick shower and checks for any changes to the rest of her genitalia. While her clit and urethra seem to have vanished with the development of her dick, everything else remained in good working order down there. She even inserted a sizable dildo into her vagina as a test, and found that it seemed to enhance the sensitivity of her penis.

For the rest of the day Emily experiments with her cock, all the while making notes, taking samples, and recording measurements. By the end of the day she's pleased to discover her penis has nearly doubled in size. For the first time in months she goes to bed excited for work on Monday.
