SW-601 Glasses-Wearing, Serious Cousin in a T-Back! My earnest, bookish female student cousin had zero sex appeal, so I never saw her as a woman, but the glimpse of her T-back created an irresistible gap moe! She was actually a secretly naughty girl.

My cousin is a very serious, glasses-wearing student. She wasn’t really my type, so I hadn’t paid much attention to her, but while we were studying together, I caught a quick glimpse under her skirt and saw she was wearing a thong. The unexpected contrast was incredibly appealing. When my cousin noticed my gaze, she came closer and teased me. Before I knew it, she had stolen a kiss, and then led me into an intimate encounter.
