Welcome to my bedroom... slave
Oh I love that... Your nipples are aching and tingling now, 'My' cock is throbbing against the elastic bands and aching for my touch...
I've got my hands down my knickers now, slowly stroking around my wet pussy while thinking about all you slaves doing this for me. Torturing yourselves for my amusement, begging to cum and to take those evil elastic bands off.
You know that mouthwash you have on your desk now, I hope there's still some left in the cap that you measured out for your nipples. If you haven't done this yet, measure some out carefully into the cap.
Now, dip your index and middle finger in the mouthwash, really coat them in the blue menthol liquid. You can guess where this is going can't you.
I want you to coat the head of your cock in the liquid, rub it all over using your fingers. Everywhere from the very tip right down to where the elastic bands are wrapped around nice and tightly. Dip your fingers in the mouthwash again and add a second coating, make sure you really do coat the helmet of 'My' cock in the lovely menthol liquid. It should start tingling almost immediately...
