Ask him to eat her out!

"Hold up!" Alice halted his advance with a nervous cry, earning an annoyed grumble from the prick. "I've never had someone as handsome as you go down on me... Think you could eat me out, first?" she asked in the sexiest voice she could manage, batting her eyelashes at her lover for effect. He grinned in reply, forcing a sigh of relief from Alice. He began dropping to his knees, ready to go to town on Alice's barely-legal twat.

"Sure thing, babe... Sorry, I got ahead of myself!" he purred as he settled into a semi-comfortable position. Finally, some time to thi-, Alice's thoughts were violently derailed when he started devouring her fragile cunny. "Omifuckingod!" Alice gasped, her mind totally focused on the activities below. The man slurped, sucked, licked, and slurped her hairless muff like it was caviar. Minutes passed, and Alice was certain at some point she came, until he finished up.

Back on his feet, the man grabbed Alice's hips excitedly, pulling her hips against his groin. "Fuck, babe, now I've gotta fuck you. You're gonna make me blow the biggest load ever," he panted as Alice could feel him pressed against her groin. Then he pulled back and released her hips with one hand to guide his dick inside her. Alice gritted her teeth as his dick slid smoothly into port, the feeling of his bare flesh filling her sensitive hole a perverted paradise.

He was so warm, and thick, and... And hard. God dammit... No way I can remember what I needed now... Fuck, might as well just ride this out, Alice gave up after several minutes spent futilely trying to remember that she'd forgotten to make her studly lover wear a condom! He pumped eagerly into her teenage pussy, her greedy muff hungrily devouring his dick with each thrust. He was throbbing violently inside her, and his pace was picking up. Shit! He's already cummin'?

Then she remembered what she needed to do; right as he moaned, announcing his orgasm. He planted his length inside her as he filled her, hands anchoring their hips together like steel. "Wait! Pull out! Pull out! Shit!" Alice shrieked, struggling against his iron grip. It was too little, too late. "I'm not on the pill! Pull out!" she repeated her demand, her voice full of panic as he started panting wearily, indicating that his orgasm was slowly dying off.

.....

After a monumental display of stupidity like that, it was no surprise that Alice stuck around. The man got her nice and pregnant just hours into her first transformation, and it was all her fault. She thought he was a decent guy when he offered to help out with the kid; until she realized what he wanted in return. She was to be his housewife for the rest of her life. By the time Alice's new body was 25, she had five kids.

By thirty, he had put three more into his hapless household whore. She only stopped getting pregnant after that because he lost interest in emptying his balls into her. He went back to breeding drunk bitches at the bar, and despite not allowing Alice to sleep around, he didn't even try to hide his infidelity. Not like Alice had a choice anymore; she had eight kids, no identity, and, unlike her old self, no degree or job experience. Alice was a fucking idiot.
