After also pulling down his black boxers, she took a firm hold on his large erection. Snape took this opportunity to cast a Muffliato spell as well as an Invisibility charm on the pair of them, getting caught with his pants down would be unimaginable. Resting on her knees, Hermione supported herself up against his thighs and brought her mouth straight down on his tool.
"Uh!" Snape panted with his eyes tight shut and a look of pure pleasure pain on his face, "Hermione I insist tha- Oh Merlin, do that again!" he growled over her skilled actions. Hermione was currently sucking his on his cock and had managed to swallow him whole whilst massaging his sensitive balls. Snape's grasp on the arm rest tightened into a white knuckle grip and his other hand was in amongst her mass of hair, encouraging her head further forward yet again.
Realising that her Professor was close to climax, Hermione concentrated her actions on the base of his shaft and worked it at his preferred pace and grip. Soon, the bitter taste of his seed greeted her tongue.
"Hermione! Uh, uh!" he yelled furiously, simultaneously coming deep into her throat. Spurt after spurt of his seed erupted deep within him and shot onto the roof of her mouth. He released her head and instantly dropped his arms to lie either side of his body, his cock still out and now flaccid, not that he cared. A very pleased Hermione took a large enthusiastic gulp, swallowing every drop of his seed, knowing that he was still watching her. He already felt a twitch in his crotch again.
Hermione got up, brushed her knees and fixed her hair and in the mean time Snape did his trousers up again and attempted to compose himself once again.
"Who'd have thought that your area of expertise had already so thoroughly explored the art of pleasure and seduction?" he flirtingly whispered into her ear.
"You wouldn't know… I'm not done with you yet." she teased, to this Snape raised his one eyebrow in a seductive fashion and slowly pushed Hermione back down on to the sofa.
