Got the glass? Good. Put it down for a minute, you're cock is starting to get soft so start wanking again. Get it as hard as you can.
Right... I want you to shit for me. No, not in the toilet. Right here in front of me! You're not going to wimp out on my now are you? You said you would do eveything I told you to.
Go on, squat down... Now grab the glass and hold it over your cock. Thats to catch any piss that leaks out. With your other hand I want you to hold it just under your arsehole. You're going to catch your shit as it comes out. Don't you dare drop any on the towel or I'll make you pick it up with your mouth.
Ok are you ready? Good, now squeeeeeeeeeze..... push that poop out into your hand.
How does it feel? Nice and warm? Make sure you get it all out. Ick... thats so disgusting!
When you're done, set the glass down and stand up.
