She runs her fingers over the woman's smooth, bare pussy, feeling the heat and wetness that betrays her excitement. With a mischievous grin, Mari retrieves a powerful electric massager, pressing it firmly against her friend's girlfriend's clit. The room fills with the hum of the machine and the girlfriend's gasps as Mari expertly teases her, pushing her boundaries and bringing her to electrifying heights of pleasure.
