Stepbrother checks for stepsister's IUD

Step brother is just trying to start a puzzle to get his mind off work and stress while his girlfriend was away. His step sister is getting ready for a date and hookup with her boyfriend but she wants to make sure her IUD was in (wink wink). She tricks him into sticking his big cock into her pussy to check for it. He has no idea that he's about to enjoy fucking his step sister and release a huge cum load in her pussy.
