It's only a oneshot but the story goes where the uke and the seme lives next to each other. The uke always have sex with others where the seme notices this and the seme can't have sex with anyone because his d*ck is too big. One time, if I remember correctly, the seme and uke had a drink together, and they suddenly interchanged souls. Then this uke wanted to have sex with the seme because he has always wanted a big D in him. After that, the uke revealed he also have a bigger D than the seme then he f*cks the seme too. (The uke prepared the seme's body when they changed souls). ლ(´ڡ`ლ)
