MIDV-103 My sister-in-law's pose made me unbearable

One day I went to stay at my brother and his wife's house. When I looked into my sister-in-law's room that my brother had asked her to be an underwear model, my sister-in-law is someone who practices posing with extreme underwear! I lost my reason when I saw her posing and then I swallowed my sister-in-law's body.
