Gotta be careful or those insatiable cum guzzlers will suck the soul right out of your dick. They will leave you a dried up husk, then find more jizz to fill their bellies.

but that sounds like the ideal way to go... let them have every last drop, the soul is a fair price

They can have a little bit of delicious tasty sperm. But if they try to suck out my soul, they will be punished! (The punishment is more cock)

their greed will be their own undoing. they get one taste of the soul and are sentenced to your hard labor

At least they won't starve.

well then that sounds like a win win.
