Sophie, a blonde lesbian in bondage, is led to the whipping post by her mistress. Her plump ass, encased in a minimal thong, is the target of tonight's BDSM session. The mistress, a dominant lesbian, orders Sophie to strip and insert her panties into her mouth. Sophie complies, her humiliation evident but so is her arousal. The mistress takes up her whip, a long, cruel thing that sings through the air before biting into Sophie's flesh. Sophie's ass jiggles with each strike, her moans muffled by her panties as she takes her punishment like a good sub.
