My husband and his female friend have an ambiguous relationship

My husband's female best friend lost a drinking game and was dared to reveal the most intimate thing she'd ever done with someone of the opposite sex.

She suddenly turned to me with a mischievous grin: "I once gave Oscar a handjob."

The room erupted in shock.

I clutched my five-month pregnant belly, feeling it tighten and harden.

She seemed to only just realize what she'd said, shrugging nonchalantly:

"Oh, it was when you'd just gotten pregnant and he was blackout drunk. He was really uncomfortable."

"No need to thank me, sis-in-law. Just helping out a friend. Better than him cheating because he couldn't hold it, right?"
