A 23-year-old amateur 4.5-tatami mat housewife, Ms. Natsuki, is featured in the "Natsuki Hoshino SY-222" series.

Opening the window revealed the Kanda River. In her dilapidated four-and-a-half-tatami mat apartment, the married woman discovered happiness… and love. Just as I was having a drink at noon, the phone rang. I wanted to ignore it, since it was just another sales call, but for some reason I answered. It was the mother of one of my tutors calling. “There’s something a bit complicated…” Sensing something was wrong, I asked her to come over. A little while later, a young woman with a face resembling Sakai ○na, wearing a white patterned dress, arrived. Upon seeing her, I immediately recognized her as the woman I liked during the visit. As we brought out a cake and engaged in a mundane conversation, the woman's expression turned slightly sad, and she lowered her head. “Teacher, what I want to talk about is about my son…” She continued with a determined look. “Actually, my son is my husband’s stepson, not my biological son. So, although it’s not for that reason, I’ve felt quite distant lately… a bit estranged… He hasn’t called me ‘Mom’ yet.” I see. No wonder she looks so young… "With 35 years of teaching experience, I'll solve this problem! To be honest, about 20% of the parents in my class are divorced, so there are quite a few half-siblings. Basically, it requires skin-to-skin contact. Please leave everything to me." I gently hugged my wife from behind. "Ah...it's okay now." As she pushed me away, her skirt rolled up, revealing her fair legs. I instantly lost my mind. Her full breasts, clearly visible even through her clothes, were roughly kneaded, and her lips, still lingering with the scent of cake, were taken away. "Such full breasts are such a waste! Next, I'll teach you real skin-to-skin contact." I stripped off her clothes and sucked on her enormous breasts, which I couldn't grasp. Her cute pink nipples seemed to react to my tongue, beginning to erect. At the same time, my wife's breathing became heavy, and her private parts became wet. When I played with them with my fingers, they made lewd squelching sounds. I recklessly enjoyed her full breasts. Her firm, youthful skin, untouched by childbirth, was like a sweet, obscene lump of flesh, like cake. Her breasts, soft and elastic like chiffon cake, were simply irresistible. Unconsciously, my penis was sucked into her breasts. "I... didn't come here for this..." I shut her up with useless small talk, making my penis hard again. But such a young face with such large breasts, it's like something out of a porn manga. If you look closely, her body shape is also like something out of a porn manga. With an overwhelming desire, I planned to ejaculate on this young face, so I rubbed my penis in front of her. "What?!" I couldn't possibly ejaculate here. And so, my hard penis was inserted deep into her throat. The sight of her crying, drooling, and whimpering made me even more lustful. Finally, the moment for my penis and her vagina to make skin-to-skin contact had arrived. Parting the thick labia, my penis was enveloped by warm folds of flesh. "Please ejaculate!" Because it felt so good, I thrust back and forth violently, her sensitive vulva overflowing with vaginal fluid, her voluptuous body convulsing as she gasped for breath. The entrance seemed to be the ultimate climax, and when I clamped it with a clamp, she let out a beast-like sound and went. Each push and shove caused her full breasts and belly to sway, a truly indescribable sight. Watching my young wife, her face flushed with pleasure as I suffocated, I felt an intense urge to ejaculate inside her. "Wife, let me get pregnant," I murmured, my sperm gushing passionately into her womb. Skin-to-skin contact is how trust and love are built…
