U-lock as proof of ownership. Pure schoolgirls are forced to wear a U-lock instead of a collar, losing their freedom and compelled to obey men's commands. Enduring torment on their sensitive bodies, they suppress their reluctance as they're made to take the erect cock placed before them deep into their mouths. Further restrained in this state, they're treated like sex toys. Helpless, their legs are spread open, penetrated, and crushed under the man's intense desires. Subjected to relentless, non-consensual creampie after creampie, their minds and bodies gradually shatter.
