Abuse yourself
Lube up your dildo. You may use real lube this time. Or you can just suck on it again. By now you are probably more used to that. Lay on your back. Your cup should be still in reach of your hand. Lift up your ass and remove your buttplug in one motion, try to make it pop.
Next you are going to fuck your asshole again. Hard and slow keep changing from time to time.
But at the end I want you to at least gape a little. When you are ready to gape, remove your dildo and push 2 fingers in your hole. Next you're going to spread your fingers in order to open up your hole some more. With your other hand you will grab the cup and pour all that delicious content in there. I want you to know how it feels to receive a huge load!
Grab your plug and stuff that ass shut again. We wouldn't want to waste anything now would we?
