I saw my friend’s tongue in my sister’s pussy and freaked out

The young man's morning began as usual. He was just going for a walk, not thinking about anything in particular, when suddenly he stopped dead in his tracks near the front door. My sister brought her friend home. It seems that the bitches were so passionate about each other that they began to lick pussy as soon as they crossed the threshold. This was a very exciting sight, so much so that our hero could not resist and decided to join the libertines, who were not at all against this situation. The trio started FFM and had a great time!
