2.7.17

veṇor iva sphuṭataḥ śabdānukaraṇaṃ dūtkṛtam//

At this time the sounds Hin and others may be made, alternately or optionally, according to habit. When the man, making the sound Phat, strikes the woman on the head, with the fingers of his hand a little contracted, it is called Prasritaka, which means striking with the fingers of the hand a little contracted. In this case the appropriate sounds are the cooing sound, the sound Phat, and the sound Phut in the interior of the mouth, and at the end of congress the sighing and weeping sounds. The sound Phat is an imitation of the sound of a bamboo being split, while the sound Phut is like the sound made by something falling into water. At all times when kissing and such like things are begun, the woman should give a reply with a hissing sound. During the excitement when the woman is not accustomed to striking, she continually utters words expressive of prohibition, sufficiency, or desire of liberation, as well as the words "father," "mother," intermingled with the sighing, weeping and thundering sounds. Towards the conclusion of the congress, the breasts, the jaghana, and the sides of the woman should be pressed with the open palms of the hand, with some force, until the end of it, and then sounds like those of the quail, or the goose should be made.
