SONE-737 Business trip with drunk K-cup boss Minami Haru, one hotel room, one bed, virgin's chance

A dull, inexperienced man goes on a business trip with his idol Haru-senpai, who has huge breasts and is excellent at her job, but he messes up the hotel booking, leaving only one room and one bed. She goes to bed happily, seemingly not caring, and he wonders if the alcohol and the situation give him a miraculous opportunity to push for sex with her despite being a virgin.
