Bellatrix loved the sound of little Draco's moans, as well as his way his voice trembled as he begged. She could feel the tiny sausage throbbing in her moutuh and watched his spasming legs. She sucked faster and harder, bobbing her head back and forth as she rolled her tongue around it. Then she pulled out her wand aiming it at the boy and silently cast the engorgio spell, causing his shaft to grow to the size of a full-grown man's temporarily. She then began to suck even harder, even letting the hard shaft down her throat. The woman gagged on it as the swollen head hit the uvula dangling at the top of her mouth. The gagging sending vibrations along the shaft that was encapsulated in her tight throat.
