The 4th installment of the popular series! My new little sister is a high school girl who attends a super slutty girls' school! She's always so defenseless and unguarded, so I get a hard-on every day because she flashes her panties, breasts, and nipples! I'm embarrassed to admit it, but my penis is so big that I can't hide my erection! I thought I'd end up getting found out and it was bad! But then she got turned on by my big dick! She's fucking me wherever I go! And my little sister is super horny! I forced her to cum inside me over and over again, and she fucked me over and over again until she was satisfied!
