He was skinny, meek and frightened. She was quite a looker and I just knew my cock would fit into her perfectly.I could feel her pussy lips round my s...aft. Then I looked at the young boy. "You know what a cuckold is don't you? " I asked. He nodded. "You know the cuckold duties I take it." he again nodded. "That's fine.
