Unfortunately it's not, but i love that one haha
Thanks!
It's about a straight guy who gets obssesed with playing with his ass 'cause of a girl he frecuently had sex with, who gives him a coupon or something like that to go to their store and try something "new", so she plays with his ass and he ends up loving it. He even ditches school to stay at home and masturbate. I only read one or two chapters so I don't know how the story unfolds. Thank you! :(
