Oooh, a moan ... I guess 'frustration' is the right answer.
Do you think I have a nice butt?
Your tongue is hanging out. That's a 'yes' too, I guess.
So how long do you think your wife would lock your chastity device for if she knew you were flirting around with your daughter's mostly naked teenage girlfriend? A week? A month?
I suspect she'd go for more actually. Two months? Three? Imagine how frustrated you'd be after three months of having your cock locked up!
