■ Synopsis:
"Yoko Fukamori," a 34-year-old virgin, is dating you (referred to as XX in the main text).
When Yoko finds out that you're not a virgin on the day of your first time having sex, she's furious that she's offering her virginity but not getting one in return, and later comes up with a bizarre plan: to go back in time and have sex with you when you're still a virgin.
I used a time machine I built in two days to go back to my college days and try to seduce her, but I was shot down because she wasn't a virgin.
After failing miserably in high school, she finally conceived and is now heading towards you, 13 years later...!!
