Her brother is the third

She likes when her husband brings a guy home and has two cocks to please her but this time it was a complete surprise. He invited her brother to have dinner with them at a restaurant, but she thought it was a normal family dinner. Only after they left the restaurant and went home her husband told her if she would like to have a threesome with her brother. That night it didn't append. Only a month later she felt she would do it. She said it was great and already did it several times after that.
