Wake up your drunk sister so you can fuck her without her remembering

This guy is very clever and he knows that if he wakes up his drunk sister just after he has fallen asleep because of the fart he is carrying, the next morning he sure doesn't remember anything. So he touches the ground by touching her pussy and then sticks his cock in his mouth to start enjoying his lips. That's when the dog wakes up totally gone and bewildered. The brother tells him to keep sucking and then orders him to get up and stand on all fours so that he can stick the tail well to the bottom. The next morning with the hangover, he sure doesn't remember.
