The best nut you will ever get comes from having a nice fat dick with a mushroom head rubbing up against your prostate deep inside your ass. The best position to accomplish this is lying on your back with a pillow under your ass,your head flat on the bed, with your legs spread apart and in the air. Have your boyfriend get between you legs facing you with his legs extended out behind him in a pushup position. His arms should be beside your shoulders. Slip the head of his cock inside you and have him start out with long slow deep strokes, pulling far enough out so that the ridge on the head of his dick is just inside the rim of your asshole. DO NOT TOUCH YOUR DICK. Wet your fingertips and rub your nipples with your arms crossed. Right hand on left nipple and left hand on right nipple. Gradually he should speed up his thrusts until his nuts are slamming hard against your asscheeks. Encourage him by saying things like "tear that motherfucker up, baby!" After a short period of this , your asshole will begin to clench and grab his dick as it tightens up. This tightening wil make his dick get that much harder and cause him to want to fuck your brains out, which at this point is a VERY GOOD THING! You will begin to feel the most incredible sensation begin to creep all over you as your prostate begins to quiver. Remember, do not touch your dick. Your boyfriend will begin to get very close to cumming and you will be too. Just let yourself go, don't hold back. Think only of that big dick ramming in and out of you. Chances are very good that before you know it ,you will blow a huge load, and your cock might not even be hard. When this happens, your asshole will go into complete convulsions. It jerks so hard that his dick might slip out. With a little experience you will be able to tell when you are about to blow, and can ask him to keep his cock buried deep , so that when you cum it stays inside. He will love you for it because it feels like a slippery death grip on the head of his cock and will make him blow his jiz way up inside you. with experience the two of you can even get to the point where you both get off at the same time. That gorgeous hunk of meat named Monster has the kind of dick that real authentic size queens like me dream of having deep inside them. He would make me cum almost instantly.
