Made an appointment with the master for a long time, finally got played by the master
Took off the master's white bondage pants and directly picked it up to smell, that's perverted enough!
The cheap dog with a big thick dick is still rock hard, of course, need to control it properly
Didn't expect to finally ejaculate without warning in the most degrading posture!
