So I didn't pay much attention, but this is what I think this

Earned her a reward

I’m not stopping until I taste cum

Not stopping until I get my reward

Sucking until I get my reward

I’m not stopping until I get every last drop.

Not stopping until I get my reward :)

Mouth pleasure is the ultimate reward, and I'm not stopping until

Helping daddy until I got my reward

This cup is your little reward, overflowing with your desire,

I’m not stopping until my mouth is filled with cum for me to

I’ll work for it until I’ve earned the reward of your cum
