A day trip for outdoor adultery with Hitomi Honda, my mom friend and secret lover. Despite the rainy weather, excitement overwhelmed me during my first outdoor exposure experience with a mobile vibrator. My erection grew hard, stimulated by her erect nipples, while the sound of rain amplified our moans. The wetness between my legs wasn't from the rain—it was proof of genuine arousal. Unable to hold back, I erupted with a creampie in an open-air bath. Later, I made her perform a blowjob right after making me pee standing up in a men's public toilet, leading to a series of intense humiliation acts. The encounter ended with a deep, full creampie.
