Drops

Not sure about the other two, you decide to select the drops.

Drool (common)

Trait: Bigger is better
Your dick will grow to nine inches, become more sensitive, and will allow you to cum multiple times without getting soft.

Again, a physical change, but it makes you more and more wondering if the app isn't really responsible for your tongue. If it's true, a big cock able to stay hard and cum multiple time, is the perfect addition.

But it's not as perfect as you hoped. As the morning goes on, you feel more and more tight in your pants, but also, just the texture of your pants is making you hard, causing more pain from the pressure. It comes to the point that you have to go to the bathroom to open your pants, discovering a massive cock, not just long, but also wide. Touching it, it twitches and jolts of pleasure courses through your body. It's kind of problematic, so you decide to jack off in the stall. Oversensitive, it doesn't take long before you cum, but as the app predicted, it doesn't grow soft. At least it's slightly less sensitive, so you get it into your pants as best as you can, the tip pokes out above your belt and is only hidden by your shirt.

Thinking straight is not easy, since every time it goes soft, the tip rubs the belt and gets hard again. Still, you manage as best as you can to finish your day. Walking back home, you try again to knock on Jane's door, but this time, she answers.

"Hey, you're back! Wanna use that tongue of yours again?" She says.

"Yes, and more..."

"Oooh... Come in, then!"

You follow her inside and she takes off her pants, before sitting on the couch, spreading her legs.

"I dreamt about that tongue of yours, you know."

"There will be something else that you will dream about, soon."

"You're getting confident. I hope you'll deliver."

Getting on your knees, you start kissing and licking her her thighs while passing your hands over her legs and belly. Coming closer and closer to her pussy, you could smell her arousal and couldn't wait to play with the inside of her honey pot. Still, you took your time, to the point that she pushed your head closer so she can feel your marvelous organ. Once you slipped it inside, she moaned loudly.

"Fuck, I needed this so much! My fingers couldn't scratch that itch."

You play in her rubbing every side, sucking her clit and she quickly gets a powerful orgasm. Shacking for a moment under the pleasure.

While, she was recovering, you grab a condom that you bought before coming, an extra large, and pull down your pants. Still shaken up by the orgasm, she notices your massive member.

"Oh, shit, you weren't lying, it's a beast!" She mumbles.

"I told you, you'll dream about it."

You put on the condom, it's tight, and you don't feel as much as when you don't have one, but here it may be better. You wouldn't want to cum hastily. So, you get closer to her and grab her thighs, pushing your cock against her wet slit.

"Mmmh... fuck..." Jane moaned. "Slowly."

You get as careful as you can and get most of your cock in before pulling back and pushing again. She moans in pleasure and you pump slightly faster every time. Even with your condom, the sensations are incredible, and you have to focus to not cum too fast. But at some point, you can't help it, and you come in the latex. Luckily, you don't get soft and can continue. But Jane moves on top of you and starts riding you on the rug. You let her do and decide to play with her tits, which makes her moan louder and louder. You come a second time before she, herself, gets another orgasm. The squeezing of her pussy around your cock makes you cum a third time, but suddenly something feels strange, you feel more sensations around the tip of your cock.

Jane goes pale, sobering from her orgasm. "I think your condom broke..." She said.

"Shit... I'm sorry... I think it was too small... Despite being XL."

Jane stands up and drops of cum fall down her pussy, your condom wide open around your cock.

"Oh, fuck..."

"Well there is still, the morning after pill, right?" You say.
