Sleepover takes a sexual turn so hot

The original plan had been so innocent and even silly that they hadn't understood. The night had started normally, they had all put on their pajamas, it was comfortable and cool, they had watched a movie, eaten popcorn and even played a pillow fight, however things changed when the brother of one of them entered the room. The boy could not hide the big erection that caused him to see them all on all fours playing, and no one expected that it was his own sister who laughingly approached him and grabbed his pants and gave him a weight on his hard cock, from there the whole tone changed.
