My girlfriend is cute and smart and she's an anime faggot like me
The other night she and I were cuddling in bed and she started humping me and whispering "oniichan oniichan" and that turned me the fuck on
so I called her "oneechan" and then she stopped and looked at me and I said "what is it" to which she replied "I always wanted a twin brother so we could fuck all the time" (she's an only child and all I have is a younger brother)
so all night long we were humping and calling each other oniichan and oneechan and I came in my underwear and we were pretending we were brother and sister trying to sexually please each other without having sex and it was fucking hot
