A forbidden relationship with my best friend's girlfriend... I couldn't resist the attractive body before my eyes... "It'll be a disaster if this relationship is discovered..." Using Aika's aggressive advances as an excuse, I justified my affair and spent three days in my best friend's bed, making love to her over and over again. Feeling guilty, I despise myself for shaking my hips so hard against my best friend's girlfriend, but at the same time, I feel proud of myself for seeing Aika's face writhing with pleasure. No one knows what will happen if this continues...
