But if the woman has an enormous abdomen, projecting by reason of its obesity over her thighs and flanks, it will be best to lay her on her hack, and to lift up her thighs towards her belly; the man kneels between them, having hold of her waist with his hands, and drawing her towards him; and if he cannot manage her in consequence of the obesity of her belly and thighs, he must with his two arms encircle her buttocks, But it is thus impossible for him to work her conveniently, owing to the want of mobility of her thighs, which are impeded by her belly. He may, however, support them with his hands, but let him take care not to place them over his own thighs, as, owing to their weight, he would not have the power nor the facility to move. As the poet has said:

If you have to explore her, lift up her buttocks,
In order to work like the rope thrown to a drowning man.
You will then seem between her thighs
Like a rower seated at the end of the boat.

If the woman's belly is enlarged by reason of her being with child, the man lets her lie down on one side; then placing one of her thighs over the other, he raises them both towards the stomach, without their touching the latter; he then lies down behind her on the same side, and can thus fit his member in. In this way he can thrust his tool in entirely, particularly by raising his foot, which is under the woman's leg, to the height of her thigh. The same may be done with a barren woman; but It is particularly to be recommended for the woman who is enceinte, as the above position offers the advantage of procuring her the pleasure she desires, without exposing her to any danger.

In the case of the man being obese, with a very pronounced rotundity of stomach, and the woman being thin, the best course to follow is to let the woman take the active part. To this end, the man lies down on his back with his thighs close together, and the woman lowers herself upon his member, astride of him; she rests her hands upon the bed, and he seizes her arms with his hands. If she knows how to move, she can thus, in turn, rise and sink upon his member; if she is not adroit enough for that movement, the man imparts a movement to her buttocks by the play of one of his thighs behind them. But if the man assumes this position, it may sometimes become prejudicial to him, inasmuch as some of the female sperm may penetrate into his urethra, and grave malady may ensue therefrom. It may also happen - and that is just as bad - that the man's sperm cannot pass out, and returns into the urethra.

If the man prefers that the woman should lie on her back, he places himself, with his legs folded under him, between her legs, which she parts only moderately. Thus, his buttocks are between the woman's legs, with his heels touching them. In performing this way he will, however, feel fatigue, owing to the position of his stomach resting upon the woman's, and the inconvenience resulting therefrom; and, besides, he will not be able to get his whole member in the vulva.

It will be similar when both he on their sides, as mentioned above in the case of pregnant women.

When both man and woman are fat, and wish to unite in coition, they cannot contrive to do it without trouble, particularly when both have prominent stomachs. In these circumstances the best way to go about it is for the woman to be on her knees with her hands on the ground, so that her posterior is elevated; then the man separates her legs, leaving the points of the feet close together and the heels parted asunder; he then attacks her from behind, kneeling and holding up his stomach with his hand, and so introduces his member. Resting his stomach upon her buttocks during the act he holds the thighs or the waist of the woman with his hands. If her posterior is too low for his stomach to rest upon, he must place a cushion under her knees to remedy this.

I know of no other position so favourable as this for the coition of a fat man with a fat woman.
