Rika, a 20-year-old science major, submitted herself for an AV. She's usually dedicated to her studies and known as a typical "science girl," but her reason for joining isn't just financial—she also wants to enjoy sex, aiming for a two-for-one benefit. What a greedy little personality! Drawn by her charm, we immediately had her reveal her lingerie-clad body. To our surprise, a slender figure wrapped in sexy pink lingerie appeared before us. The side-tied thong design made her beauty almost breathtaking. When kissed, she let out adorable moans, and removing her bra revealed perfectly shaped breasts greeting us with a bounce. Her nipples' color and size looked incredibly natural and highly attractive. Slipping off her panties revealed a completely shaved pussy saying hello. Inserting a finger into her slit, she was already dripping wet and slippery. Stimulating her with fingers and tongue, her shy gestures of turning away only made her cuter. Next, switching roles, she moved from nipple licking to blowjob. Using her tongue and fingers skillfully, she sucked with impressive technique. Finally, the long-awaited penetration scene began. Slowly entering her, the squishing sounds and her moans instantly plunged us into full-on erotic mode. Thrusting my cock against her slim body made Rika even more aroused. In cowgirl position, her expression of losing herself in pleasure while rhythmically grinding was irresistible. Her bald pussy clearly visible as my cock slid in and out drove me straight to maximum climax. Rika also wore a satisfied smile, bringing this perfect session to its ultimate conclusion.
