We were kissing each other all other, your hard nipple in my mouth. I’m kissing your breast, your stomach, and suddenly you push me back and take my nipple in your mouth. Your mouth is so warm and you tongue is driving me crazy. You kiss my stomach licking my belly button, sticking your tongue in it. I jump from the sudden.
