First story:Nah, seme make a deal with his partner but he's still fucking others it's not fair for the uke, and His "no can do" when uke asked him not to do it with others is sooooo disgusting. He deserve to be the uke. I know the author think of the dirty to deliver this story but he/she must make that seme an uke
Second story: it's good.
