Kelly decided to go out for a smoke. She didn't usually do it unless she was with certain friends, but something about today was just making her feel naughty, and she wanted to be looked at as a bad girl.
On her way over to the malls smoking area though, she saw the most beautiful dress she'd ever laid eyes on. It had a black and white cow print pattern all over it, and she just had to go and try it on. It fit amazingly, and even held her new breasts well enough that she took off her bra and put it in her bag. She left the changing room in it, paid for it and went outside, confidence soaring.
Kelly scoped out the other people outside smoking, and clocked a cute guy on his own. Kelly caught him eyeing her up as she sauntered over to him.
"Hey, I don't suppose you have a spare cig I could have?" Kelly smiled at him.
"For you? Definitely." He handed her one, and even lit it for her when she put it in her mouth.
"Thanks" Kelly said, exhaling. "I'm Kelly by the way" holding out her hand for him to shake.
"I'm Rob, and you're more than welcome."
They carried on chatting for a while longer, obviously enjoying themselves enough to stay outside for another smoke. Kelly's lust for Rob was building up fast though, her mind craving more and more for someone to fill her with cum.
Kelly felt a little unnerved at these strong desires, but she couldn't really argue with them when she'd already leaned in and was making out with Rob.
"Should we go somewhere a little more... private?" Kelly managed to pull her lips away long enough to ask.
"I dunno, you're fucking beautiful, but I'm meant to be meeting my girlfriend here in an hour though." he explained.
"An hour...?" Kelly's hand rubbed at his cock through his jeans, "so you've got plenty of time then..."
Rob grabbed her hand and started walking, leading Kelly somewhere more private. They reached a small grassy area, secluded away in a small forest behind the mall. The grass started to call to Kelly again, but not enough to take her away from her current goal. They lay on the grass, making out for a few minutes when Rob's phone went off.
"I'm really sorry, I need to take this, I'll just be a few minutes." He got up and wandered just out of sight, to take the call in private. Kelly saw an opportunity here, and quickly jumped on it. If she had to wait a few minutes for that craving, she was going to satisfy another while she waited. Kelly was quickly on her knees, bum wagging up in the air, feasting on the grass.
The numbness above her ass returned, pushing her to carry on and rewarding her with pleasure.
"Mmmmm...soooo...gooood." Kelly said out loud between mouthfuls. One of her hands had found its way up her dress and was rubbing at the outside of her pants. "Mmmmmoooooo" escaped her lips, as a black and white spotted tail started pushing out from above her ass.
Rob returned from his call, walking around the corner looking at his phone, "I'm so sorry, my girlfriend got here early so I ne- whoa". Rob's dick stood to attention pretty fast at the sight in from of him. Kelly's ass was stuck up in the air, pointed directly at him, rubbing away at herself. He couldn't see her face, but she was moaning, a lot.
Rob got down on his knees behind her, ripped off her pants, pulled out his cock and plunged into her. She was already so wet, it felt incredible. Kelly kept swallowing down mouthfuls of grass, not caring if Rob could see the tail sprouting under her dress or not.
It finished growing, causing Kelly to orgasm. "FUCK...MOOOO". Rob went into a thrusting frenzy as Kelly kept screaming, and moaning, and mooing? Her orgasm kept going for what felt like half an hour, when Rob finally came too, filling her up with his seed. He pulled out of Kelly, and she turned around, cleaning his cock with her mouth. She was only intending to clean it off for him, but once she started sucking, he got harder again, and Kelly couldn't bring herself to let go. She sucked and licked at the tip of his cock like a pro, while her hand worked at his shaft.
She felt him getting close, but had the sudden thought that it would just be wasted going in her mouth. She needed the cum in her pussy.
Kelly pulled Rob to the ground and mounted him within seconds, grinding away on his dick. The great feeling in her tits was returning, so her hands went straight to her nipples, squeezing and pulling on them as she bounced away. She could feel them growing, and milk started to leak out as she played with them.
Rob was drawn to the milk, and instinctively leaned up and latched onto one of Kelly's tits, sucking the milk out of it. That was enough to make Kelly cum again on its own, but the milk seemed to invigorate Rob. Kelly could feel his cock growing slightly inside her, driving her wild.
She started grinding on him like she was possessed, like a cum-crazed slut. 10 seconds later they were both cumming, Rob filling her with more cum that she thought a human was capable of.
Kelly let out a loud Moo, fell backwards, and passed out.
