My sister-in-law, who is in her first kiss, first sex, and first creampie, is taking away all of my "first time" from me...

My older brothers and his wife came to my parents' house for a memorial service. However, his older brother seems to think of his sister-in-law as a housekeeper, and when he has work early he goes home. I thought my sister-in-law would feel sad at my parents' house alone, so I took my car to the neighboring prefecture, but unfortunately my car stalled along the way and ended up spending time at a nearby hotel... I'm alone in a hotel with my sister-in-law, who I've always admired... And my sister-in-law kissed me gently, as if to read my heart.
