Sperm suckers.

I will make you have a dream when you next go to bed.
You will have some special, beautiful,
sexy women who need your sperm to stay alive.
They will make your balls grow to increase your sperm quantity
and make you have orgasm after orgasm, until they are all satisfied.

Enjoy, and sweet dreams my darling.
