Trouble left in the metro

Roxanne arrives at her house after a tiring night at work. She was nervous, as she worked on the subway cleaning crew and was responsible for cleaning up a puddle of something slimy that was left on the floor of a carriage. To make matters worse, she had managed to slip and get dirty in the liquid, so she needed to take an urgent shower. She also had a tremendous hard-on and couldn't wait to get rid of it, she had felt a tingling sensation in her breasts and throat earlier, but it had passed.

"Welcome back Rox, I've been waiting for your arrival." said Ursula, her lesbian housemate and girlfriend

"I'm home Ur, but I have to take a shower urgently, and I'm also very horny. Do you want to join me?" Roxanne said

"Count me in." Ursula said

The two girlfriends went to the bathroom and took off their clothes, throwing them in the laundry basket, and got into the shower together.

Instead of washing, the two started making out under the water, but when Ursula grabbed one of Roxanne's breasts, she noticed that they were different and said "Rox, your breasts feel firmer than they should be and... uh, where are your nipples?"

Roxanne looked at her breasts and felt them, there really wasn't even a trace of her nipples, and her breasts really were more rigid, because there seemed to be something big inside them, but the sensation to the touch was different and she was loving it.

"Let's ignore this little detail for now. I'm so horny and it feels so good. Just keep going." Roxanne said

Ursula was worried about her girlfriend, but as it didn't seem to be something serious and, even if it were, it wouldn't kill her because of a delay of a few minutes for them to seek medical help.

The two lesbians continued, kissing each other as they thrust one hand into the other's pussy. During this time they rubbed their breasts against each other.

Roxanne found it odd, as her tender spots seemed to be even more tender, and she also felt as if something was churning inside her breasts. At the same time her breasts seemed to be getting bigger and heavier, forcing Ursula to move away from her.

Eventually they had to break the kiss and Roxanne peeked down, confirming that her breasts were huge, they were the size of basketballs already.

"What the hell is this?" Roxanne asked

"Something serious must be happening to you Rox. There's no way breasts can grow that much in a few minutes, and swelling of this level must be serious for sure." Ursula said

"I need to go urgently to a hospital." Roxanne said

"Let's finish this bath soon and I'll accompany you." Ursula said

They continued cleaning themselves, but Roxanne was just so horny, like she's never been, and she couldn't go to the doctor in that situation.

Giving in to lust, Roxanne placed Ursula against the wall, leaving her trapped between the wall and her now huge breasts, and went back to kissing her, asking her girlfriend to help her finish.

Ursula was **** to reciprocate, so she reached into Roxanne's pussy. She felt that her girlfriend was really wanting too much, as she was salivating too much and a lot of drool was running down her chin.

The lesbian sweethearts continued until Roxanne reached orgasm, deciding to keep the kiss going as she came, but something very weird happened. It was so fast they didn't have time to act, something suddenly gushed from Roxanne's mouth straight into Ursula's, who swallowed a part in fright before separating their mouths, but the white liquid kept gushing in big loads from Roxanne's mouth, quickly covering her entire body of its contents.

Ursula managed to free herself, and looked scared at her girlfriend throwing up that white stuff, but she noticed that while Roxanne was doing this, her breasts were shrinking. She then realized that the taste and consistency of this white liquid was familiar, so she realized it was cum. She wondered how her girlfriend could vomit cum, and in such an amount that probably a thousand men combined couldn't produce.

"How crazy was that." Roxanne asked when she finally stopped puking her cum, which was apparently the end of her orgasm. Her breasts were back to normal size, but they were still without nipples.

"Something weird is going on. You threw up this much cum, and judging by the reduction in size, it was all inside your breasts." Ursula said

"So these firm things inside my breasts.... it can't be, I think they're testicles, and they're huge." Roxanne said

As quickly as they could, Roxanne and Ursula finished washing and changing and left as quickly as they could, all without them knowing the cause of it or the contagious nature of it.
