My stepsister joins me for some naughty fun with homemade porn (Surprising conclusion)

My stepsister caught me watching porn and got really turned on by it. She started to join in, giving me a mind-blowing blowjob before taking it doggystyle. But just when things were heating up, my little sister walked in! We had to quickly come up with a cover story, but the surprise visit made the whole thing even more exciting.
