Where does this quote from Achilles appear in the Iliad?

"You had no consideration for my pure reverence of your thighs, ungrateful after all our frequent kisses." Achilles says of his fallen lover Patroclus. Ive seen on on various website directly after a quote from Thetis telling him to enjoy himself with food sleep and women, but I cannot find it in the book. What book and line is this from?
