Even with the attachment that has been developing during your time as her underwear, you're not completely okay with becoming her bra again. Being reduced to an inanimate object like that, possibly forever, just seems like a foolish sort of wish. That isn't to say you're against serving her completely, though, just not in the capacity that will get you lost in the laundry at the gym. A small idea beings to bud inside your mind like an unstoppable cancer. Maybe she can use an assistant? Someone to guide her use with gun, giving suggestions and the like on how to deal with others. It is a long shot, of course, but you figure its worth giving a shot considering your only other options at the moment seem to involve Suzi turning you into another option. Better her slave than her sock, you think. Your somewhat jumbled musings are interrupted as you feel Suzi's soft palm rub against your shaft once more, playing with your cock once again.

Suzi continues to jerk you off during this, greedily attempting to milk you for all your worth. Once finished, you are unable to hold yourself up any longer, and you collapse onto the floor. Your belly comes into contact with your seed, as disgusting as that is, prompting a laugh from your master.
