The mouth is the ultimate tool for delivering pleasure to the penis most efficiently. The softness of saliva, the warmth of lips, and the complex movements of the tongue combine to draw out even deeper sensations. There's no need for unnecessary extras like using hands. Simple back-and-forth piston motions are enough to repeatedly engulf both mind and body in waves of pleasure. Once you experience its allure, you'll become obsessed with continuous ejaculation—will your brain be able to withstand it, or will you have no choice but to indulge in pleasure until your balls are completely drained?
