Cocksucking is the act of sucking off a partner using their mouth. Most men do not like this act because it is perceived as an attack on their manhood, but my boyfriend, StepMom, teaches me how to do this correctly. She taught me the art of mouth jobs when I was a teenager and I now perform them on a regular basis in the privacy of my own home. If you want to learn how to blowjob your boyfriend, I highly recommend taking a few tips from my website! You don't have to go and find some porno scene for your threesome....
