Leech's Relatives in the Swamp

In the murky mire, dwell leech's kin,  

Sisters named Gimme and Gimme More,  

Slithering shadows, demanding their feast,  

Symphonies of greed in swampy chords.  

"Care to donate?" whispers sly Sister Gimme,  

Not to charity but to her appetite,  

While Gimme More waltzes boldly near,  

Cravings infinite, insatiably clear.  

Leech, a gentler member of this clan,  

Prefers his meals with less demand,  

But together they form a gluttonous trio,  

Echoing hunger through every bio.  

Oh, beware, kind souls by the marsh,  

These sisters don't ask; they lunge and parch,  

Life's symmetrical duo craving encore,  

Meet Miss Gimme and Miss Gimme More.
