Yui, my cousin who lived in the countryside, has grown up and come to Tokyo to attend college, so her family asked me to look after her. From what I remember, Yui used to be a tanned, tomboyish girl, but the woman who showed up at our meeting spot was completely different. Pale skin, big tits, a huge ass—this mature beauty took my breath away, and before I knew it, she'd kissed me passionately, catching me off guard. She pushed me down and confessed, "I've liked you for so long," then stared at my cock and whispered, "Uncle, you're so big..." before giving me an intense blowjob. Right there, she suddenly said, "Wait, I want to show you something," and revealed herself in an outrageously sexy transparent bunny outfit, boldly seducing me. Completely overwhelmed by her irresistible charm, I ended up passionately making out with Yui. She dominated me with aggressive slutty moves—cowgirl position, body-wash titty fuck, blowjob, creampie after creampie, cumming on me again and again—seven times total. Adoring her uncle deeply, she utterly melts under my touch in this 120-minute episode packed with pleasure, starring Yui Tenma.
