At my classmate Rinka's house, I repeatedly thrust inside her bareback, guilt forgotten. Her pure white, soft F-cup breasts sway as her nipples throb intensely. I slide smoothly into her sticky, hairless teenage pussy. From front to back, I pound into her uncontrollably. In cowgirl position, the natural beauty of her bouncing breasts captivates me, accompanied by her tearful, whimpering moans. After sex, a service time begins—freely groping Rinka's sleeping body. Whispering "It's our secret from school friends," a pure yet intense sexual desire awakens, making me climax again and again—a boy meets girl story.
