It may take practice to master, so have an alterna-penis handy. Place the condom in position to roll straight down with the reservoir tip on top. Place condom in mouth and rest behind teeth, aligning mouth to target. In one smooth motion, s lide mouth and condom all the way down. Be sure not to bite.
Nothing kills the mood quicker than the last condom rendered useless.
Dropping the prophylactic to the floor in a sweeping gesture of satiated lust is fine, in a Rover-less world. Dogs sniff around, and if your pooch has access to the room where the action is, you'd better be sure to securely dispose of the condom. You're talking about a species that, if unsupervised, will tear through a cat box like an hors d'oeuvre platter. They don't have discriminating taste buds, and your dog will delight in chomping through the afterglow. I know, It happened to me.
