チンポを入れて岩のように激しくするテクニック

If you want to get your cock hard as a rock, there are several techniques you can use. In this video are some techniques I use... Foreplay is a great place to start, as it will help get you in the mood and make you more aroused. You can also use massage techniques to stimulate your cock, as well as use lube or sex toys to help increase the sensations. If you have a partner, engaging in sexual activities like oral sex, mutual masturbation, and intercourse can also help turn your cock on and get it hard as a rock.
