[HUNTB-452] "Just a kiss. No more than that." Two people who have been burning up with a passionate kiss where tongues are intertwined can not stand it. (Censored)

My brother-in-law waits without sleeping for his brother who doesn't come home until late at night. While talking to me to fill the loneliness, we are attracted to each other. I've been patient for a long time so as not to cross the line, but my sister-in-law's promise of "only kisses" leads to a life of kissing. However, my brother's sudden transfer. I'm going to be separated from my sister-in-law...! When this happens, it's no longer just a kiss! Push down the hesitant sister-in-law and insert it! Immoral sex that can not be stopped while understanding that it is a quagmire affair!
