My little sisters invited me over again and when I showed up they were ready for me. They said they need to keep my sperm count up by making sure I'm cumming regularly until they are ovulating. They offered to suck my cock with sisterly love, and they didn't have to ask twice, as long as they don't tell mom and dad. They laid down on the bed and let their heads hang off so they could get facefucked and gag on my cock, then they got down on their knees and looked up at me while sucking my cock with only the love that a sister could. Then I pressed their faces together and they shared rope after rope of hot cum on their mouths and chins. My family is just the best. I can't wait until they're finally ovulating!!
