This is the third clip in the "Male vs Female slave" experiment series. In this clip you will see Officer Melisande Sin using Her massive strap-on to destroy and stretch the butthole of both Her female and male slave. They might be shivering in fear but both the slaves are fortunate to be in Her presence. Locked in Officer Melisande's prison, their only purpose is to be experimented on, used and abused by Her. Watch as She flawlessly penetrates Her slave's personal space by Her big strap on.
