Hot Sister Spencer Wakes Me Up For Some Fun With My Big Dick

I was just getting up from a nap when the next thing I know my sister, Spencer, is jumping up and down on my bed telling me to wake up. Spencer can be so annoying sometimes, she always needs so much attention. Spencer wants me to go in the pool with her but I really don't feel like it at all. She keeps begging me and the next thing I know she is grabbing my cock, of course, it is hard! I have morning wood, Spencer loves rubbing my throbbing cock through my underwear. I am not sure if Spencer is ready for what is coming next, I can not have her just rub on my cock without fucking her. I fuck my hot sister so hard till I just cum all over her pretty face.
