"It does take a certain amount of practice to perfect." Sara said with a sly grin. She chuckled with Gabrielle's musings. Something about this girl made her think that she was a natural liar. She was a female of Slytherin now. The were all very natural liars in some shape or form. "Hm, I don't know. I'm sure before long, you'll have plenty of practice. The Slytherin social ladder is practically built on lies and deception."
Sara growled again. "You're so sure of yourself, you little french whore." Her body may be reacting and submitting to Gabrielle, but her mind surely wasn't.
She wasn't able to keep to her threat though, as her orgasm shook her. Given no time to recover as Gabrielle continued her powerful thrust, Sara moaned loudly in pleasure and took it in stride, already working on her second orgasm.
Allowing Gabrielle to flip her, Sara rolled onto her stomach and wasted no time in arching so her arse was raised in the air for Gabrielle.
