I would start by gently caressing your chest and stomach, slowly moving my hands up to stroke your arms and shoulders. I'd then focus on massaging your back and neck, easing any tension you might have. As I work my way down, I'll tease your abs before cupping your sac, gently rolling my fingers over it. Finally, I'll take one of your hands in mine and use it to guide me as I stroke myself against you, building up pleasure until we both reach satisfaction.
