Erica said. “What thing?” “Us having someone else in bed with us…” She was embarrassed about it when we weren’t actually having sex, but she had a threesome fantasy. I didn’t know where it had come from but she’d started talking about it last year, started whispering it to me during sex, had started sucking her vibrator sometimes which I fucked her. I assume imagining another man. “There’s a guy at work,” she said, “I was talking to him.” “A guy at work?” She nodded. “That doesn’t seem the best idea.” “I know.” “But you did anyway?” She shrugged. Everybody likes Erica. Everybody. She doesn’t have enemies. She goes to the gym and watches what she eats. She avoids TV and tries to improve her mind, when she’s not working, which is a lot. She earns more than me. I try to be supportive, and just turn over when she sets the alarm for five. I make dinner most nights and usually do the housework. When she first started talking about threesomes a year ago, I went along with it.
