After dating her sister "miyu" for three months, I was invited to stay over at her house one summer day. As I encountered her older sister "wakana", she was half-naked, sweaty, and moving around the house without a bra or panties. Her perky nipples and hidden manhood were driving me wild (sweat). Unable to control my arousal any longer, I finally... No bra, no panties! She has no idea how stimulating this is for someone like me (sweat). My supercharged libido takes full advantage of her unaware teasing, causing my rock-hard cock to throb uncontrollably. Despite being close to her, I can't hold back my intense orgasms and continuous, sweaty piston fucking that won't stop until I cum multiple times! Is she feeling it too? Her slender body shakes violently as she cums again and again while I continue to release inside her! **Note: Content may vary depending on distribution method.**
