My stepsister and I have always talked about how hot it would be to have a threesome. However, she seemed not as excited as I was. Of course the biggest problem was deciding which girl do we bring into our bed. The minute I mentioned her BFF Lola she would say that I was just making up an excuse to fuck her. I promised her it wasn’t like that.I basically thought, I would never win anyways. Then one day I decided I would come home early cause I was tired and my work meeting was cancelled. Once I walked in through the door I can hear a noise coming from the bedroom. I approach the bedroom door and that’s when I can make out the noises. I’m like that sounds like sex noises. I’m thinking maybe my stepsister is watching some porn. So I burst through the door to surprise her but the surprise is on me. I see her and her BFF having sex! I can’t believe what I’m seeing but I guess I now know why she didn’t want to have the threesome. She wanted Lola all to herself.
