The serum works: Emily discovers she's growing a penis

The next morning Emily wakes up late. She yawns and stretches, thankful that it's the weekend. The events of last night slowly come to mind as she wills herself to get out of bed. She pauses as she remembers injecting herself with the serum. In a quick panic she begins checking herself, making sure nothing went horribly wrong.

At first it seems like nothing has changed from the night before, which is mostly a relief. She sighs with mild disappointment, but it's not much of a shock. None of the other serums she'd tried had worked on the rats either. Emily reaches for her journal to write down the results of the experiment, but something makes her pause.

There's a sort of tingly feeling in her clit. The tingle isn't very strong, but it's clearly there. She gently inspects the area with her fingers and doesn't notice anything different, but decides to keep an eye on it. She records her findings and goes about her day.

For the most part it's a pretty uneventful Saturday. She takes a shower, gets dressed, eats breakfast, does some grocery shopping, and takes care of some chores around the house. The tingly feeling remains constant, so much that it fades into the background if she isn't focusing on it. The only other symptom of note is her heightened appetite. Despite a big breakfast and full lunch she's famished by dinnertime.

For dinner Emily has plans with a friend from college, a woman named Alice. Alice and Emily live very different lives, but they still keep in touch. Every month or two they try to catch up over a hot meal. The pandemic put a damper on their routine, but they manage to make it work over video chat.

"Hey girl!" Emily says as Alice answers the call. "I just got my food, what about you?" She asks, resisting the temptation to dig in early.

"Hey!" Alice says, taking off her mask. "Food should be here any minute. I just checked." She adds, walking back from her front door.

"You still wearing a mask and doing the whole no-contact delivery thing?" Emily asks, trying to find a topic to take her mind off the delicious aroma of the takeout containers.

"Yeah..." Alice says, a little embarrassed. "You know, for Dan." She explains.

Emily can hear Dan playing his game in the background as Alice walks past him. "Suck my cock!" He shouts into the mic, causing Alice to visibly cringe.

Emily raises her eyebrows. "Well I guess it's working."

Alice rolls her eyes. "Yeah, maybe a little too well." She says with a touch of sarcasm.

"He's gonna catch it sooner or later, they always do." Emily says with a sigh.

"Unless you finish that vaccine you've been working on." Alice replies optimistically.

"Actually, I think I made a bit of a breakthrough on that, but not in the way-" Emily is cut off by a phone notification.

"Oh, that's the food." Alice says, putting her mask back on and returning to the door.

The two friends chat and dine, catching up and talking current events. Emily scarfs down her meal, spending most of the conversation nodding and going "mm-hmm" while she chews. Partway through the call she becomes acutely aware of the tingling in her crotch, it feels like it's growing more intense.

"Hold on, I gotta go to the bathroom." Emily interrupts her friend before pausing the call. She hurries to the toilet and cautiously inspects the affected area.

Emily can immediately tell something is happening. Her clit is so swollen that she can even see it through her panties, poking out to make a little bump of a bulge. She carefully pulls down her panties, feeling a mixture of excitement and fear. Her clit has grown remarkably fast, becoming wider and longer. As the tingle became stronger she could actually see it twitch and grow.

She rushes to grab her journal and began to document everything. What she was seeing was very promising, her hands trembled as she wrote it all down. This was exactly what she had expected from a successful serum, it was almost like she was going through the changes men experience but in reverse order. She jots down some quick predictions based on that idea.

It doesn't take long before one of her first predictions comes to pass. As the tingling increases to a crescendo, her clit begins to twitch and engorge. "Oh my..." Emily mutters, transfixed by the sight of it. "If total impotence precedes the final shrinking, then could this be an erection?" She mutters in awe, not quite sure what an erection should feel like.

Gradually the tingling feeling fades, replaced by an intense feeling of arousal. Emily's clit has swollen even larger than before, becoming firm and flushed. She gently touches it, noting its tumescence. It still doesn't look much like a penis, instead of pointing up it's pointing almost straight down, and there's no hole at the tip, but it's already much more of a penis than it was this morning.

Emily gasps as she revels in the enormity of her discovery. This could change everything.
