In my second year as a working adult, self-diagnosed with "second-year syndrome," I once had a girlfriend back in school—but she dumped me after only three weeks. Desperate for love, I stumbled upon a unique "rental girlfriend" service with a special trait: every girl has an H-cup bust. It's a rental girlfriend service exclusively for H-cup lovers! As a massive fan of big breasts, I instantly got hooked and began keeping three rental girlfriends at all times. Immersed in days filled with nothing but pleasure, I couldn't stop grinning. Honoka Kadowaki, with her vibrator-like lips and dynamite body, an irresistible contrast. Momono Hanada, a mysterious, glasses-wearing, big-breasted beauty with a shy smile and healing charm. Luna, hailing from Bali, Indonesia—slim yet blessed with balloon-like huge breasts. An overflowing lineup of ultra-large-breasted "girlfriends"! 120 minutes of maximum love and heart-pounding excitement pushed to the limit!
