NPEN-003 A serious and innocent amateur girl reverse propositions a shy boy. If he can ejaculate within 10 minutes, he wins a prize of 1 million yen.

A chubby, fair-skinned amateur girl with an L-cup bust! We had her take on a game where if she could make a virgin ejaculate within 10 minutes, she'd win a million yen prize. The rule is no direct 'let's do it' lines; she has to tease and seduce him into it. Highlights include: A man who finally succeeded in picking up a girl, a virgin otaku with no interest in women, aggressively pursuing Natsuki-san, asking 'Do you like breasts?' while showing her chest but looking down and not opening his eyes, Natsuki-san getting fed up with his reaction and showing her real L-cup breasts, covering his face with her skirt to show her panties, and forcibly seducing him! A flustered virgin who is clearly erect, Natsuki-san getting aroused and letting the virgin touch her bare breasts for guidance, Natsuki-san saying 'I want to do this with someone I like' while dripping pre-cum and acting submissive, asking 'Am I not attractive?' while spreading her vulva and masturbating, the virgin unable to hold back any longer and sucking his erect penis until he ejaculates, 'It's not over yet!' as she twists and sucks his glans, straddling him and forcibly inserting it in a cowgirl position! Small, jerky hip movements leading to intermittent orgasms, getting on all fours and spreading her vulva while begging for his penis, 'Ah this is too much! Wait! Wait!' while having multiple orgasms, encouraging internal ejaculation as the virgin's penis nears ejaculation, 'You can still go, right?' straddling the virgin and starting cowgirl position again, Natsuki-san alone having multiple orgasms while the virgin is left behind, the virgin ejaculating inside her again, 'Let's do it again!' spreading her legs wide for normal position and begging for his penis, the virgin going wild! Furiously thrusting and making him cum again, another internal ejaculation. Result: Satisfied after 4 internal ejaculations!
