Addicted

Addictive - your effect,
Like a true narcotic.
Demand arises periodically-
Through nerves
Through blood
To every hair-pores.

It's three,
Then three;
It's seven,
Then seven.

Pumping heart
Thumping finger(forbidden!)
Some days pumps faster
Thumps harder;
Some days pumps slower
Thumps softer.
