Emily decided to take it a bit slower this time and give Eli a gentle wake up fuck.
She placed her hands on his chest and rocked herself back and forth slowly, clenching herself so she gripped it even tighter. The way she was leaning pushed her tits together, Eli's view must have been glorious.
He let out a pleasurable moan, and Emily could have sworn he was getting bigger inside her. She leaned into him and planted a long, passionate kiss on his lips, then sat upright, one arm across her tits holding them in place and balancing her other arm on his leg, then started to slide herself up and down on his cock, keeping the slow pace.
She mooed quietly with each bounce, the walls of her pussy expertly working his dick, tightening and relaxing at just the right times.
The look on his face told her he was already about to cum, but she kept her speed slow to let him build up.
"Harder. Faster. Please" he begged.
She really wanted to do as he told, but she kept her composure and carried on.
"No. I want you to build up to it slow, make lots of cum for me and shoot it all inside me." She said seductively.
"But--" He tried to argue.
"Shut up and let me fuck you. Make lots of cum for me. Maybe you'll even get me pregant." Eli moaned loudly and stopped talking, clearly enjoying being the one not in charge for once.
Emily certainly enjoyed being in charge. Her own orgasm had already built up, but still she maintained her pace, dragging it out for as long as she could. Her mooing got louder and more frequent as her body quivered, her mind telling her to go crazy and fuck his brains out, but she still she kept bouncing on him slowly and meticulously.
Eli started to grunt, ready to blow his load, so Emily leaned forward again, hands on his chest, and grinded herself against him as hard as she could. Her slow, careful orgasm finally skyrocketed as he started pumping his huge load into her.
"MOOO - OOO - OOOOHHH" she screamed into the air. That was her most cow-like moo yet. She looked down at her body to see the fur hair growing thicker. It started first on the top of her feet, and spread up her legs, carrying on up her thighs and around her crotch.
She could feel it over her arse too as she continued her slow grind against him, his cock still throbbing as it pumped the remainders of his balls into her.
The fur continued to spread up her body, the dark hairs moving around her stomach and towards her back, so fine white hairs could move up her belly towards her tits.
Emily stopped grinding and grabbed at her breasts, ready to feel the fine hair sprout over them as she rode out the final wave of pleasure.
The spread of hair stopped at the back of her neck, and left a V of exposed human skin above her breasts, before continuing along her arms, covering them in the black and white splotches.
Finally it stopped at the back of her hands and hit Emily with one last burst of pleasure.
"MOOOOO" she screamed, as her finger and toe nails thickened, turning black.
She remained on Eli's cock for a few minutes, the pair of them panting heavily. She managed to stop stroking herself, and placed her hands on Eli's chest again and opened her eyes.
She hadn't even noticed he'd gone through the same change, her own pleasure made her completely oblivious.
Finally she rolled off him, and laid by his side, the two of them staring into the ceiling. Eli was the first to break the silence.
"So...now that we've got a moment where we're not fucking...what the shit is happening to us?"
