Step Sister walked in on me jerking off - She offered to let me fuck her feet

My step sister walked in on me, she caught me stroking my dick while watching footjob videos. I started to pull my pants up when she told me to stop, she stood there staring at my hard throbbing dick. She then noticed what I was watching and said she had never done that with a boy. She slid her flip flops off and sat at the end of my bed, when she put her beautiful feet up on the table I didn't know what to think. Now looking at Her sexy young feet made my dick fully erect again. She asked if we could try it. Without hesitation I pressed her feet against my hard dick, the feeling of Her soft young feet touching my cock was amazing. Her perfect toes and sexy nail polish made it so hard. The way she could rub my cock with her feet made me wonder how many footjobs she has really given. She seemed so turned on watching my cock fucking her feet. Finally after not being able to hold back I unloaded a massive load of cum all over her feet and legs.
