Once you have finally shit out the final grapes, collapse onto your back in utter exhaustion. As you lay there, spread your legs so you have access to your cock and your asshole.
With one hand, stick the dildo into your ass and begin fucking yourself. With the other, begin jerking off at a rapid pace. Make sure your legs are spread as wide as they can be in the air, just like a slut in a porn film. Scream in delight and pain after all that you have been through so far.
