They slept eventually, tangled together in Kim’s bed, Katie between them, her head on Rob’s chest, her mother’s arm around her waist. The apartment was quiet, the early morning light filtering through the blinds, and Rob lay awake, listening to their breathing, feeling their warmth, trying to process what had happened.
He’d crossed every line he’d drawn for himself. He’d touched a sleeping girl, had sex with his girlfriend’s daughter, had participated in something that society would condemn, that could ruin them all if it ever came to light. He should feel guilty. He should feel ashamed.
But he didn’t.
Instead, he felt ... complete. Like a missing piece had finally clicked into place. Katie’s hand was on his stomach, her fingers tracing idle patterns, and he knew she was awake too, thinking, feeling, processing.
“Are you okay?” he whispered, not wanting to wake Kim, who was snoring softly behind her daughter.
Katie tilted her head back to look at him, her eyes soft, sated, happy. “I’m perfect,” she whispered back. “Is that ... is that weird? That I’m not weirded out?”
Rob shook his head, his hand finding her hair, stroking it gently. “I think ... I think this is what your mom wanted. For you to feel safe. To feel good. To learn that sex isn’t something to be afraid of.”
“She’s been planning this for months,” Katie said, a small smile playing at her lips. “I didn’t know, not exactly, but I knew she wanted me to be comfortable with you. She kept asking about my fantasies, about what I wanted. I told her I thought you were hot, and she just ... smiled.”
“She’s fierce,” Rob said, his eyes finding Kim’s sleeping face, so peaceful now, so different from the commanding presence she’d been last night. “She knows what she wants, and she gets it.”
