HUNTC-172 "I'm wet... grab a towel!" My dress got soaked in the sudden downpo

My sister-in-law came home in a sudden downpour and her dress was soaked, her underwear was completely visible! Her wet clothes were sticking to her body, and her body lines were also visible. I couldn't take my eyes off her, so I stared at her as she dried herself with a towel, and she noticed my erection. I thought it was bad, but then something unexpected happened! My sister-in-law suddenly got close to me and wanted my dick! I couldn't resist, so I ended up having sex with my sister-in-law...
