My stepsister woke up and caught me fucking her friend

My stepsister’s friend caught me jerking off my cock in the toilet and gave me a blowjob. Later that day, I sneaked into my stepsister's bedroom and fucked her friend’s pussy. While I was fucking my stepsister's friend, my stepsister woke up and joined us in fucking. My stepsister's friend ate my stepsister's pussy while I fucked my stepsister's friend doggystyle.
