You and your step-sister are in your room, when you ask her if she matched with you on tinder. She said that it was on purpose to play a prank on you but that she didn’t mean anything by it. You explain that you always swipe right because it’s harder for men to get matches. She emphasizes with you and tells you she is willing to help. Eventually she starts noticing you are hard and starts sucking you cock. You end up fucking your step-sisters tight pussy and cumming in it.
