Spell of cum addiction

Helpless Samora lays on the cold floor, while shaman casts his spell on her. She can’t escape when strange aura surrounds her. Energy pushes itself inside her, deep to her mouth and to her belly. Samora can’t do anything to prevent it.
After a minute she starts feeling strange. New, unknown lust fills her body. She feels hungry, very hungry. But it’s not food nor water she needs now. Her mouth is watering when sudden thought about cum appears in her mind. She already accepted lot of goblin’s sperm, but she feels that she wants more. In fact, she needs it.
Shaman smiles as he disrobes, waving his huge for to her. Samora moves on her fours and walks to him, almost mesmerized by the size of his manhood. She can’t take her eyes off his huge balls. She can imagine them being full of sperm, that will soon fill her mouth. Saliva is leaking out her open lips.
“No!” says suddenly shaman, when she’s just about to taste his dick “Not without proper asking!” he adds.
