All Night from White Stains by Aleister Crowley
 

All night no change, no whisper. Scarce a breath
But lips closed hard upon the cup of death
To drain its sweetest poison. Scarce a sigh
Beats the dead hours out; scarce a melody
Of measured pulses quickened with the blood
Of that desire which pours its deadly flood
Through soul and shaken body; scarce a thought
But sense through spirit most divinely wrought
To perfect feeling; only through the lips
Electric ardour kindles, flashes, slips
Through all the circle to her lips again
And thence, unwavering, flies to mine, to drain
All pleasure in one draught. No whispered sigh,
No change of breast, love's posture perfectly
Once gained, we change no more. The fever grows
Hotter or cooler, as the night wind blows
Fresh gusts of passion on the outer gate.
But we, in waves of frenzy, concentrate
Our thirsty mouths on that hot drinking cup
Whence we may never suck the nectar up
Too often or too hard; fresh fire invades
Our furious veins, and the unquiet shades
Of night make noises in the darkened room.
Yet, did I raise my head, throughout the gloom
I might behold thine eyes as red as fire,
A tigress maddened with supreme desire.
White arms that clasp me, fervent breast that glides
An eager snake, about my breast and sides,
And white teeth keen to bite, red tongue that tires,
And lips ensanguine with unfed desires,
Hot breath and hands, dishevelled hair and head,
Thy fevered mouth like snakes' mouths crimson red,
A very beast of prey; and I like thee,
Fiery, unweary, as thou art of me.
