Look at my sister. She is a pro and loves cum. Dont you want to be like her? Iknow you do. Keep stroking. Now I know you have to be close to poping the cock, so I want you to point your little cock down into the glass. You are going to have yourself a slow gasm. Whats that you dont know how. Well I will tell you. Stroke that cock all the way to the edge and then just as you reach it, go one stroke over, and you will ooze some of your thick milky man juice into the glass. Now that you have the hang of it. I want you to do this 3 times. Go on cum boy and do it.
