@KeyholeHer
It's the keyhole.
She likes that she can look at it and it'll look like she's looking her in the eyes when really she's just painfully obsessed with that hole.
Even if Abby dropped her pants, her eyes would be focused on the other hole the whole time.
@Unlimited_Illya It doesn't even feel like Abby is being a bad girl. Illya is a naughty naughty girl who enjoys this. Her tongue feels to hot and wet and it's getting all the salty sweat!
