[HUNTC-246] - A promised life of only kissing with her sister hidden by her parents. "Just a kiss... Because they're brother and sister ..." I can't stand the promise of only kissing my adult sister. If you return home after a long time ...

If you return home after a long time ... - The sister who was waiting for me was a sister who was in love a long time ago. In the past, I lived like a lover. I was troubled by the forbidden love between my brother and sister and escaped from it. - When I returned home, I kissed my sister, who had become even more beautiful as an adult, for the first time in 5 years with a "promise of only a kiss". However, it doesn't stop there, and she gradually becomes unable to stand the kisses that are violently intertwined, and she crosses the last line. When this happens, the two who can't stop anymore are in a quagmire of incest.
