Compulsive Porn Watcher
Back, slave? I hope you brought what I asked you to bring...
Fill that slutty little asshole of yours with that butt plug. Yes, you may use some lubricant, but only if you thought of bringing it along with the plug, you can't go get it now!
If the plug inflates, pump it 4 or 5 times, make it so you feel full and just a tiny bit uncomfortable.
If it vibrates, turn it on and adjust it at 3/4 speed.
Kneel down now. Sit on your ankles, pushing that plug deeper. Make it impossible to slid out off your ass.
And now, start stroking, slut. Stroke with 5 fingers, slide your hand from the head of your cock to your balls, and again to your head. Stop at your head for a bit and massage it with your thumb with circling movements. Repeat this way of stroking all the time, at a medium pace. Stroke for 10 minutes. No cumming, no stopping this time. So be careful!
Use your other hand to randomly change the speed of the vibrations. Never turn it off though.
