Short and easy read about a man discovering his wife has cheated. Not an erotic read and not a BTB. It is what I feel is a realistic situation and a common reaction and action that follows.
Male-perspective bisexual: NY doctoral student, Aiden Macallum, is in an open marriage of convenience with older Columbia U English professor Sandra Gainsworth. They both fall for New Zealand author Bram Overby, who invites Sandra to take a sabbatical at his hedonist artists' colony NZ beachfront house. Sandra accepts, Aiden tags along. Both become sexually embroiled not only with Overby but also in a community where everyone is doing everyone else and everyone wants to do Aiden.
I had a couple of teachers I wanted to thank. First was my Earth Science teacher. He was a sweet old lonely man. I walked into his classroom after the last student left for the summer. I pushed the door closed and pulled the shade down. "Vat are you doing Mz. Cox," he asked. "Something to thank you for the time you took with me and your other students Mr. I." I dropped to my knees in front of him, and by the time he inhaled enough air to speak, his cock was in my gullet.
