You start riding Melissa, putting her in a cowgirl position. You love how helpless she is, enjoying how her huge cock feels inside of you.
"You're such a good little slut, aren't you?" You ask her, surprised where your voice came from.
Thankfully, she answers.
"Y-Yes Mistress Abby!" She said, moaning from the pleasure you're giving her.
You push her mouth onto your tit again.
"Suck." You say.
She responds by sucking your giant breast.
Suddenly, you feel a spurt of warm cum inside of you.
It felt like more than last time... a lot more. You look down at her, still sucking your tit, and her balls have grown tremendously! So has her tits, which are now lactating a constant pace, and you can watch them grow.
"Good girl. Keep sucking." You say, savoring feeding her.
