Some mutual entertainment

Once you're fully dressed, you breathe a sigh of relief! Despite the silly underwear, you finally got to wear some proper pants again. It makes you feel a bit more like an actual person! "So, what's next?" There was still so much you needed to know.

Before Gwen has a chance to reply, your belly begins rumbling loudly - and audible enough for even Gwen to hear it. "Some breakfast, by the sound of that."

A short while later, you're back in your room with a plate of stacked sandwiches. There wasn't much feminine grace in the way you hungrily devoured the snacks, but should that really bother you? It's not like you had a lifetime of experiences as woman and etiquette, you merely had the body of one. And hopefully, even that's only a temporarily deal. There's not even two days left anymore, more like one and a half!

However, your thoughts are interrupted by a knock on the door. "There's no need to be so polite, sis. We're the only ones at home," you point out mockingly, she was being unnecessarily polite. With her head low, she opened the door and entered the room.

"I uh, need your help with something." Now that's a new one. It did however make a bit more sense as she stepped forward and stopped holding her folded hands in front of her crotch - there's the bulge again! It was tenting the front of her pants in a way she couldn't possibly hide anymore. "I was hoping that it would just go away when your... transformation is done and dealt with. But I don't think I can wait that long! The stupid thing doesn't go down, it's like it has a mind of its own! How do guys deal with this?"

Slowly but surely, you piece together the information you've got so far... Gwen has a dick? "So what's the problem? Just go take care of it." She fidgets around a bit more.

With a groan, she looks back up at you. "I've got no idea how that works!"

"Wait, so you're saying you are a virgin?" Now that you think about it, she really never mentioned a boyfriend or brought any guys home... same in your case for that matter, you were so busy with high school that you never had the time for a normal, healthy relationship with a girl you fancy. Most of your knowledge comes from porn and you probably wouldn't even know where to begin to please a woman. "So we are both virgins, and stuck with the bits of the other side? Talk about awkward..."

"Well screw your awkward, I want that thing to stop being all bouncy and hard, I can barely even walk around with things being like this!" Hah, you couldn't help but snicker at that. Heck, she was right though! As a girl, being horny just means that things get a little slick down there, but otherwise you hardly even notice anything special. As a guy however? It's really uncomfortable, and anyone can tell with ease that you're 'hiding' an erection in your pants.

"For starters, it's your turn to strip. Come on, come on," you tease her, and after a frightening glare, she reluctantly does as she's told for the sake of getting it over with. It was an interesting sight, her completely flawless, pale skin without a hair on her petite body, but as soon as she took off her underwear, there was an unquestionably male part attached to her crotch. It was captivating! Her dick was only a couple inches long, probably average or slightly below. A few subtle veins ran along its surface up to the foreskin-covered cockhead. It wasn't curved in any way, pointing straight forward. It's pretty much perfectly average, pretty much just like how your own genitals looked like someone took a blueprint for 'perfect' and lazily copied the job. Speaking of which! You quickly decide to take your own pants off as well. "If I teach you how to take care of things down there, I want the same help in return," you demand. Your pussy was tingling and aching with a need for attention. The sooner that's taken care of, the better.

"That's... fine, it's fine I guess." She walks over to your bed and sits down by your side, both of you now with your new additions completely exposed. For a brief moment, neither of you knew where to begin... so you decide to take charge.

"Okay, for starters, just form a fist around your dick and go up and down. It's really as simple as that." Gwen stares back at you with an expression that could only mean 'seriously?', but she follows your guidance and begins stroking herself. She releases a soft, pleased moan with the very first motion, and keeps on moving her fist with a tight grip around her appendage.

"Holy crap... this is so... easy!" She sighs with pleasure and keeps going at it, while you're left to watch. With a cough, you draw her attention. "Oh, right! Well, first spread your legs a lil' bit like so," she instructs you while giving you an example. "Then... well, start by touching your thighs. You know, rub 'em softly, give yourself a little massage. Treat yourself to something special! When it starts feeling nice and tingly, you can start teasing your labia a bit. Play with yourself - literally! Get the blood flowing. You will know when you're ready for more. When you reached that point, it depends on what you prefer - either dip a finger into your slit, or dive just between your folds to gather enough of your juices to rub your clit. Just be very, very careful. That thing is super sensitive! Be too harsh, and it will kill your entire mood. Treat it like a flower! Find out what it needs, and then apply it, tenderly and carefully. It's like playing an instrument, put lots of effort into learning how to play, and eventually you'll get the hang of it!"

Now it was your turn to stare at her. Seriously? "You're pulling my leg, right?" After watching her shake her head, you get down to business and try to apply what you've learned. Rubbing your thighs didn't do much for you, but touching your labia? A pleasant feeling. The skin was all warm and... rubbery. You slide a finger between the folds, and gasp at how drenched you are! You didn't even notice it had gotten so wet down there! Continuing on, you use your now slippery digit to rub up and down the length of your slit before beginning to tease your clit with a feminine, excited gasp! It really was super responsive! Gentle, warm shocks coursed through you with every light touch. It's unlike anything you ever felt before!

Gwen in the meantime was happily jerking off next to you with her eyes closed. It's temping you for a moment to mount her dick and see what it's like to have sex, but you dismiss the idea... it was too risky... but god, the idea turned you on immensely! Your mind begins imagining what it may feel like to have her cock becoming a part of your body, stretching you open and violating your new cunt... "Ahnn!" You gasp and cry out! Your first orgasm as girl, your entire body tenses and shakes lightly with waves of pure bliss racing from your toes to your head! It felt like heaven!

With your eyes firmly shut, you don't even notice what Gwen was busy with...
