너의 새엄마는 너에게 따먹히는 걸 자랑스러워해

I catched you jerking off to me, even if I'm your step MOMMY but it makes me super proud! So I tell you constantly how you should keep doing it and how proud you're making me. I tease you but also give you a reward for cumming while jerking off looking at me. You're such a good boy for me!
