Secret Sex Society - Chapter 2

Carrie and her former lover share a passionate past, but something in Ben's gaze suggests he's evolved. Guiding her to a concealed chamber, Ben unveils an array of risqué items awaiting use. Carrie submits as Ben encircles her neck with a broad leather collar.
Grasping the connected leash, Ben dribbles warm melted wax onto Carrie's backside, observing her react with both pleasure and ache. With her senses heightened, Carrie gasps in rapture as Ben asserts his control, penetrating her intimately and tugging on her collared neck, adding to her stimulation by engaging with her nipples. This scene portrays a vivid and diverse peek into stimulating practices.
