Alison reports how she and husband Kent were introduced to the idea of MFM sex by one of Kent's co-workers. That sparked some shared viewing of XX videos that focused on such pleasures. Then a vacation trip to Aruba provided an unexpected opportunity to actually experience having another guy in their shared love life.
They met Adam, a personable black guy who worked as a massage therapist on the island. Later that night a massage by Adam resulted in him using his dick to give Nancy an internal "deep tissue massage" with Kent's full approval. Nancy loved it.
That was the start of a new life of shared sex play for Alison and Kent later shared with both an older and a younger lover for Alison's pleasure in the following years.
