Next Bust Size #7 (Patreon)

It's time for another booba poll. Here is a bit of backstory:
She is also one of the dark angels in Resting Church. She isn't a nun though — she was originally a holy knight, but unfortunately got corrupted and became a cum-dumpster. She has a strong will, but not strong enough to control her lust. 

What should her booba size be?
