XXX Me and XXX You

I thought we had been dating for 10 years, but for him I was just "a toy." I can't love anyone anymore. That's how I wish I was but it still hurts! After all, I was being used as an onahole for 10 years! Having only self-confidence isn't enough! While I was frustrated, my kouhai gave me a xxxx? Wait, don't tell me that's yours?
