Shakespeare talks about lust and how damaging it can be. This one is a LITTLE SPICY.

Sonnet 129

Th' expense of spirit in a waste of shame
Is lust in action; and till action, lust
Is perjured, murd'rous, bloody, full of blame,
Savage, extreme, rude, cruel, not to trust,
Enjoyed no sooner but despisèd straight,
Past reason hunted; and, no sooner had
Past reason hated as a swallowed bait
On purpose laid to make the taker mad;
Mad in pursuit and in possession so,
Had, having, and in quest to have, extreme;
A bliss in proof and proved, a very woe;
Before, a joy proposed; behind, a dream.
All this the world well knows; yet none knows well
To shun the heaven that leads men to this hell.

Shakespeare wishes he was a piano key so the dark lady could play him elegantly with her fingers. Weird?

Sonnet 128

How oft when thou, my music, music play'st,
Upon that blessed wood whose motion sounds
With thy sweet fingers when thou gently sway'st
The wiry concord that mine ear confounds,
Do I envy those jacks that nimble leap,
To kiss the tender inward of thy hand,
Whilst my poor lips which should that harvest reap,
At the wood's boldness by thee blushing stand!
To be so tickled, they would change their state
And situation with those dancing chips,
O'er whom thy fingers walk with gentle gait,
Making dead wood more bless'd than living lips.
Since saucy jacks so happy are in this,
Give them thy fingers, me thy lips to kiss.

We say goodbye to "the fair youth" and hello to "the dark lady". Shakespeare talks about cosmetics and how he thinks they are ruining true beauty.

Sonnet 127

In the old age black was not counted fair,
Or if it were, it bore not beauty's name;
But now is black beauty's successive heir,
And beauty slandered with a bastard shame:
For since each hand hath put on Nature's power,
Fairing the foul with Art's false borrowed face,
Sweet beauty hath no name, no holy bower,
But is profaned, if not lives in disgrace.
Therefore my mistress' eyes are raven black,
Her eyes so suited, and they mourners seem
At such who, not born fair, no beauty lack,
Sland'ring creation with a false esteem:
Yet so they mourn becoming of their woe,
That every tongue says beauty should look so.
