Up his bondage a little bit...

You decide that Stan's bondage needs to be a bit more severe.

Ropes swirl out from under Stan and wind around his arms and torso, holding them firmly together. The ballgag grows new straps, now sporting a full harness, tightly buckled ofcourse.

A few thin ropes wind their way around his cock and balls, acting as a sort of cbt setup. Lastly, you imagine Stan wearing a thick leather posture collar, with a nose hook attached to it. You see Stans head being raised by the collar, then hear him groan as the nose hook materializes and pulls his nostrils upwards.

Now that he´s more uncomfortable you walk around in front of him and pet him on the head. "There there, you´re doing great Stan." He looks at your pleadingly, but stays quiet. "I think it's time for a reward!" His eyes brighten up.
