My sister's friend begged me to rub her pussy to relieve the itch after seeing my big dick. (HUNTA-062)

I usually walk around naked after showering, but I didn't know my sister's friend was coming over to stay overnight. As a result, she saw my entire penis, and seeing my big dick made her take advantage of me that night! I only wanted to rub my bare buttocks a little, but in the end, of course, I got so excited that I inserted myself into her vagina and had an amazing time!
