Lesson learned 😂

So, my fiancé and I are staying at his parents and his little sister is 5 and also here, we decided to do a quickie upstairs but the door has no lock, his sister has a habit of running in here so I thought I heard her footsteps about to run in the room right as he was pulling out to cum, any who I rushed to pull up my panties and pants he ended up coming on my panties then we soon realized his sister wasn’t running in here so I went to take them off and ended up flinging cum all over my face, his face, my shirt the wall... everywhere, lesson learned no more day time quickies at his parents house😂😂😂
