Everyone is so nice on you.

Visit bathroom, then strip naked, stuff your pussy with all three of your toys, it has to be stretched.
Collar, ball gag and nipple clamps - yes.
Tie your feet to the chair, you can use your restraints or anything else.

Start studying. Edge each 30 minutes.

AFTER studying for 4 hrs you can visit bathroom, then come back.

You can't cum until you are FULLY PREPARED.

During the study if you even consider distraction - like opening social networks, your phone, even getdare - spank your pussy, move your gag one hole tighter and add a marker to your already stretched pussy. If your clamps are adjustable - make it tighter.

Note:
Use condoms for pussy insertions.
Relieve your nipple clamps if you feel numb.
Same for any other restraints.
Safety first.
