Your natural instincts immediately take over and you open your mouth and allow her nipple inside. Immediately, your mouth has a mind of its own as you press your head firmly into her breast and begin suckling the unnaturally long teat like a starving baby. The demon-woman laughs in satisfaction. “To think, that you believed me to do you harm!” she taunts. “Drink, little man. Feed your lust as you will soon feed mine.” Immediately, you feel her milk flood your mouth. Its taste immediately reminds you of the potion you got from Giacomo. You realize the potion was not a potion at all, but this demon’s breast milk! Concerned only for your blind libido, the suction of your mouth coaxes torrents of the devil’s fluid into your mouth and down your throat. She continues teasing your cock only enough to maintain your erection. In time, your stomach signals that you are full and you break the seal from her tit, making a loud 'pop'. She briefly hoses you down with milk, soaking you.
The demon has a satisfied look on her face. “Did I taste good? Was I wholesome and fulfilling?” she asks. “Since you have fed from my life-milk, it is only fair that I do the same. To be fair, 'yes', I am as fierce as I look and I will leave you sore and insensible. However, I do so to pleasure you and feed myself. Accept it and be happy.” She gives you another inhumanly toothy grin and kisses you deeply. A small pang of fear still shoots through you as you feel the sharpness of her teeth. She breaks away from your lips and sighs in excitement. “Now, I FEED!” she utters jubilantly.
