If she kept that in there and went about her day, do you think she’d feel the weight of it move around as she moved?
Her ass would convulse in waves for a bit. Probably after 15 minutes. Then again in 30. Then it feels less urgent for a while. At some point she’d realize that her hole had tightened back up — doesn’t take too long for that. At that point she might worry a bit because if she let it go without loosening her ass back up, it would hurt, probably even tear a little. Eventually she’ll have to stretch her own ass back into shape before her body involuntarily pushes out the ball.
