One day, I went to stay at my brother's house. My brother asked my sister-in-law to be an underwear model, so I looked into her room and saw her practicing posing in extreme underwear! Even though I knew I shouldn't touch her, I lost my reason at her obscene outfit and came inside her raw! From then on, I devoured my sister-in-law's body all over the house! I got turned on by her ass while she was cleaning and gave her a blowjob, had sex with her in her underwear exposed in the entrance, gave her a handjob while my brother was out, and had sex with her while she was taking a bath! I do it every day in lingerie that accentuates her feminine charms!
