Did you finish the quest line for them?
Once you do you have the choice to either keep them or give them back to Alex, and if you keep them you can take them off like every regular kind of clothing.
No...... i couldn't find this quest how to solve
Bluespace panties * Somehow fleshlights with your private bits were stolen! Alex said you can look for them in the cellblock, near the cells
how can i finish this quest? Do i just walking around and wait to pray to meet? what am i supposed to do now?
Go to where you sleep, the right side of the threeway? should trigger an event after which you can get rid of it!
