A vibrant 20-year-old girl at the perfect age for fun—the most delicious season of youth. She recently moved to Tokyo and is living alone, but her living funds have completely run out, leaving her with no one to rely on. Desperate, she kept applying for part-time jobs without giving up. During the interview, she unexpectedly revealed that she doesn't mind doing erotic things. MARIKO has a cute face and a pure, serious personality—she's never even been to a mixer. She's had six boyfriends, with actual sexual experience with five. Emotionally fragile and timid, she's clearly a shy, reserved type. When asked if she's ever had sex in an unusual place, she replied, "In a park." Passing by a park at night, she was swept up in the mood. Though she initially refused, she eventually gave in to her boyfriend's advances. Despite strong feelings of shame, she became even more aroused. When asked about sensitive spots, she shyly answered, "My breasts." Of course, her lower area is also highly sensitive, and she seemed eager for toy play. Before beginning, she took a shower and moved to the bed. First, we stimulated her breasts—the erogenous zone she mentioned. Her nipples are especially sensitive; just a little kneading made her breathing heavy ("Haa, haa"), her nipples hardening and erect. Gently licking them with my tongue, she repeatedly moaned "It feels good," quickly flipping her dirty switch. Touching her crotch over her panties, she didn't show much reaction in her voice or expression—perhaps out of embarrassment—but her hips naturally began to sway. Since she dislikes mess, I removed her panties to touch her directly, revealing her youthful, delicate labia. As I began cunnilingus, the moans she'd been holding back gradually slipped out. Applying the vibrator softened her expression, eased her tension, and she started writhing her body in earnest, panting loudly. When turned up stronger, MARIKO suddenly squirted a huge amount of fluid, climaxing intensely. She seemed even more sensitive than expected. During the blowjob, her serious nature showed in her careful, meticulous movements, taking me in gently and pleasurably. With pre-cum flowing nonstop, she dutifully swallowed every drop—driving me to lose control and forcefully penetrate her. She sincerely accepted it, lying on her back as I entered her in missionary position. While aggressively thrusting into her, I targeted her nipples—previously thought to be weak spots—and she let out loud moans as if releasing everything she'd held back, genuinely getting into it. After thoroughly satisfying her with cowgirl and doggy style, I finished in her favorite position—missionary—filling her belly completely. The obscenely hot MARIKO was so lost in pleasure, she seemed completely out of her mind. With both heart and body fulfilled, she said, "Contact me again next time." Being able to meet regularly with such a cute, sincere girl is incredibly exciting—it makes me want to plan all kinds of things for the future.
