Lips

You select the lips, and the two other images moves away to leave a window with the lip icon and a message.

Oral (common)

Trait: Made for pleasure
Your tongue will grow to four inches long from teeth to tip.

The app doesn't do anything much, and you're disappointed. So, you close it and go back to your usual business.

As the day goes by, you start feeling a strange sensation in your mouth, a little discomfort with your tongue. While you walk in the elevator of your apartment building, you look in the mirror wall and get your tongue out. You get quite the surprise as the thing comes out by several inches, long and flexible. It doesn't immediately occur to you that, it may be the app. But before you really think about it, you hear a voice.

"Wow, that must make some girls happy."

Getting your tong back in, you look at your blushing neighbor, Jane, entering the elevator. It seems it slipped her mouth so, maybe you could take advantage of that.

"I... I don't know, I have no one to try with..."

She looks at you, a bit surprised and a bit confused. So, you add.

"But if you want to try."

Jane bit her lips with a smile.

"Damn, you're straight to the point... But heck, I'm in."

You can't hide your surprise that it worked. You can't back out, now, you follow her to her apartment and she gets close to you.

"So, I'm your first?" She asks.

"Not exactly, I just didn't get the chance to use my tongue on anyone."

Jane kisses you and you answer her kiss. Your tongue somehow goes around hers, playing with it in her mouth. She enjoys your kiss while taking off her clothes and then getting in the couch, her leg spread, revealing her shaved honey pot. You get on your knees and start kissing the inside of her thighs, getting closer and closer to her crotch. She plays with your hairs during the whole session and moan softly. The closer you get from her privates, the louder she becomes. As you finally reach the wet valley, you start licking the slit, going more and more inside with each passage. Getting full inside, you move around and finds the place where her moaning is louder. It's a fun game to play, and you're getting better and better at it. It becomes faster and louder until she finally reaches a climax, and you feel her insides squeezing your tongue.

"Fuck... that was amazing..." She commented as she releases the grip of her hands on your head.

"Good to know." You answer, proud of yourself.

"Do you have any condoms?"

"Not on me."

"Next time, bring some, I'm curious to see if you're as good with your D than with your tongue."

"Ahah, see you next time, then."

You leave her apartment a bit shocked on how everything went. Still, it was amazing. You look at your tongue several times after that, to remind you that you didn't dream it. It's still long and flexible.

The next day doesn't have anything remarkable to it, you try to see if Jane is there, but she doesn't seem to be home. Finally the day after, a message reminds you about the app.

It reminds you that the app gave you that weird message about a longer tongue. But it couldn't be possible, right? An app on a regular phone could not affect your body... And now you have a bill between hands, a stripper and some drops...
