The following is a story. It is not autobiographical, but it is a story I can identify with.
She's lonely! He reminds her of just how lonely she is.... by a look, an "accidental" touch, a sotto voce double entendre.
She's been alone for seven years, well, not really alone, she has her adorable child. The child keeps her busy, frantic, overwhelmed sometimes, until now she's never felt truly achingly alone. Sure it would be nice to have a man in the house, to share the load, to cuddle, to commiserate with, to celebrate with. It hits her in times of extreme highs or lows, but it hasn't, until now, been a yearning, a constant need.
He's on a mission. He reminds her with his touch, his words, that she hasn't been intimate with a man in nearly eight years. Her mind, her heart, say NO! This is wrong, people will get hurt. His wife, her child, his child. Her stubborn, traitorous body rejects the consensus. She's HORNY dammit! She had forgotten this side of her nature, wishes now that it had stayed buried. She tries to avoid him at gatherings, his wife notices and wonders why. She's honest with her, the wife laughs it off, he's just an incorrigible flirt. Tell him you're uncomfortable, he'll back off. She does, a mistake. Now he knows. He's winning the battle! Her body is on his side, her heart and mind will capitulate.
He steps up his campaign. Calling her on one pretext or another when he is alone, telling her what he is doing to himself as he talks to her. She stops answering her mobile, but can't ignore the landline, what if it's an emergency, the child or her parents? She hangs up on him. But then he's there, at her front door, late, when her child is asleep, telling her he's sorry. He doesn't mean to hurt her, he loves his wife, but he's drawn to her. He will stop. He doesn't, he won't. He kisses her. Her mouth says NO! Her brain screams NO! Her body overrules with an emphatic YES! God YES! I have missed this! I love this!
It doesn't end well for her.
