Similar to a blow job alarm clock or alarm cock, with variation and added steps. If the person that you are sleeping with is still sleeping after you wake up and you want to wake them up but have trouble with conventional measures, try this:

1.) Start off by getting an erection

2.) Get your penis next to his/her mouth

3.) At the same time, pinch their nose shut and insert your penis into their mouth as deep as it takes to close off normal breathing

What this should do is close off normal relaxed breathing causing the receiving person to wake up gasping for air like a Flounder fish out of water.
