E3: Use the material

"I need to think about this..." you said as you left leaving them unsure.

Two of them were crouching naked on the floor. Vibrators sticking out of Jennifer's naked cunt and out off Martin's ass. They were both keeping the same position. Crouched, with hands behind the backs, heads up, chest forward. Metal collars adorned both of their necks.

Even their hair were now dyed the same raven-black colour.

Both of them were breathing heavily, both close to cumming even with this strenuous position, then a sound of vibrator hitting the floor echoed the walls. With a growl of despair Martin realised that it was his that dropped. Next to him your mentor opened her mouth to let out a scream of ecstasy as she reached her orgasm.

"You almost had it today. Well. Maybe next month..." you teased Martin cruelly running your hand over the chastity cage locked over his cock and balls.

Maybe one day ... maybe one day you will let him cum ...
