You’ve been dating Natsume, your rich classmate, for 3 months now. You’re very excited when she invites you over to her family’s manor while her parents are on vacation. But when you meet Natsume in the manor’s garden, she’s with a blonde girl you’ve never seen before.

“So… I’d like you to introduce you to my girlfriend,” Natsume says nervously. “I was too afraid to tell you I’m bi… so I thought it would be easier to just show you.” After a long pause, she whispers “If you watch us make love… you can have us both tonight.”
