Working double shifts, I have a three-year-old son but couldn't get him into daycare—my neighbor Sari Sato has been taking care of him. Living alone as a single mother, she often comes over, seeking companionship out of loneliness. One day, I returned home to grab documents from work and caught Sari masturbating while watching adult videos. Despite being a student, her body is slightly developed, and when I accidentally spilled tea and touched her thigh, the sensation overwhelmed me, triggering instant arousal. She shyly says, "Mister, no... this is bad," yet clearly shows interest in sex. Watching AVs together, I become increasingly captivated by her small frame trembling under a vibrator. She murmurs, "I feel so safe when you hold me," and asks, "What makes you feel good, mister?" expressing a desire to take initiative. Desperately moving her hips for me, she swallows my cum with determination, stirring deep emotion within me. An unspoken afternoon encounter—taking the virginity of a lonely girl next door. This video features various scenarios including floor-focused missionary, ceiling-focused cowgirl, first-person cunnilingus, vibrator play, face-to-face seated positions, and doggystyle. The contrast between her petite body and intense passion evokes an overwhelming, heart-wrenching desire.
