A special event featuring RIN-chan, a cosplayer dressed as a certain cyber diva, at a monthly photo shoot. During the session, an overzealous fan suddenly appears and starts stripping off his pants, catching RIN-chan off guard. Despite her confusion, she keeps up her charm and poses politely. But the excited otaku goes further, removing his underwear to reveal his thick, rock-hard cock. RIN-chan, with her soft, puffy lips, gently licks the urethra, teasing the frenulum with delicate flicks. She tenderly strokes his balls while sucking eagerly on the pre-cum oozing out, then deeply swallows the entire shaft, performing an exquisite blowjob all the way to her throat. Overwhelmed by pleasure, the fan erupts in a massive facial cumshot. RIN-chan, stunned with a dazed expression, radiates both cuteness and eroticism in this must-see scene.
