Oshi ga Ore wo Suki Kamoshirenai!? Kono Sex wa Souteigai.

"My favorite idol... is whispering so close in my ear while rubbing my dick!?"

Kairi is a university student who's in love with Rin, his favorite idol. He was so serious about his love that his growing infatuation made him unable to attend live concerts anymore... But they became brothers because his father remarried!! Not only that, but the guy himself showed up in his room saying "I'll help you out" when he found Kairi secretly jerking off! "I have to stop..." he thinks, but even though he wants out of this crazy situation, he can't win... against Rin's good looks!!! His heart and his body heat up as all his sensitive spots are teased relentlessly... "I'm gonna come!!!" Now that they live under the same roof as brothers, Kairi's love grows stronger as the mean idol toys with his emotions!
