The bow is a sexual act involving the fingers of one lover with the female sexual organs of another. If you want to do this you must slide the index finger inside of the vagina, and rub the top vagina with your thumb. While this is happening, take your other hand and gently pinch the clitoris and lips, stretch back towards yourself and release. Repeat multiple times for a great time.
Kmac was doing the bow on his woman last night. She loved it.
