The milky way

The beautiful latino woman was riding him cowgirl style, dancing like a slutty flame, panting and screaming. Josh was fascinated by the sight of her athletic belly and wide hips waving with grace and energy, and her enormous chest bouncing with every thrust. He suddenly grabbed them and started kneading them, to which she reacted with a high pitched and surprised cry.

"Sorry, did I hurt you?" he exclaimed, still pounding her.

"No, not at all!" she answered without slowing down her movement. "It's just... My breasts are more sensitive than usual, I didn't expect it. What...?"

She stopped talking when she saw milk dripping out of her nipples, rapidly flowing into several thin streams down her boobs and onto her lover's hands. She stay shocked for a few seconds, still jumping on his dick but looking at her chest in astonishment, then tears started droping from her eyes.

"Are you okay?" Josh asked, now seriously worried.

Her eyes met his, and a smile slowly draw itself on her lips, cautiously, as if she was afraid of awakening from a dream.

"I'm lactating!" She was overjoyed. "Do you know what this means?"

He looked at her, dumbfounded. He vaguely remembered a rule he passed a few moments ago about milk, but it was in the heat of the moment and he wasn't sure.

She grabbed his hands to press it against her tits so he could knead them even more tightly and she redoubled her efforts in pleasuring him.

"There's only one instance of women starting to produce milk spontaneously without being pregnant, like it's happening to me: Doctors of the GRAFG having sex for the first time with their male patient. Nobody knows what it's due to, but to this day it only happened for those who actually graduated. I was chosen to be only an assistant, but my body react like a doctor's body."

Despite having said that she didn't mind being an assistant as long as she was working with Dr. Sterensky, it was obvious that she was taking it to heart. Josh didn't suspect a rule he wrote just to fulfull a minor fantasy woulf have such a huge effect on somebody's feeling. So much that, when she leaned backward arching her back and screamed her lungs out, he thought she just orgasmed from joy alone. It didn't kill his mood, though, and he didn't take long for him to cum in her pussy, roaring in pleasure as milk was pouring on his hands.
