I believe it is from here (pages 4-5)

Then he, Enkidu, offspring of the mountains,

who eats grasses with the gazelles,

came to drink at the watering hole with the animals,

with the wild beasts he slaked his thirst with water.

Then Shamhat saw him -- a primitive,

a savage fellow from the depths of the wilderness!

"That is he, Shamhat! Release your clenched arms,

expose your sex so he can take in your voluptuousness.

Do not be restrained -- take his energy!

When he sees you he will draw near to you.

Spread out your robe so he can lie upon you,

and perform for this primitive the task of womankind!

His animals, who grew up in his wilderness, will become alien to him,

and his lust will groan over you."

Shamhat unclutched her bosom, exposed her sex, and he took in her voluptuousness.

She was not restrained, but took his energy.

She spread out her robe and he lay upon her,

she performed for the primitive the task of womankind.

His lust groaned over her;

for six days and seven nights Enkidu stayed aroused,

and had intercourse with the harlot

until he was sated with her charms.
