This is pretty satirical, there's just something funny and pure to me about Audrey and Seymour overreacting to a curse word.
"Oh my gosh! Oh! Oh! Oh, fuck!' Time stood still. They both froze. Audrey immediately gasped and clasped a hand to her mouth. Seymour's jaw dropped, he wasn't entirely sure of what he'd just heard. He'd never even heard Audrey say "damn" despite having been with her through a number of broken dishes, burnt cooking and general forgetfulness.
What was his next move? Should he change the subject? "Do-do you want me to keep going?" He coyly asked, completely unsure of what the moment called for.
All that Audrey could muster was a meek "Uh-huh." Seymour resumed their lovemaking and in one minute and 13 seconds, they climaxed, simultaneously, and silently.
He rolled off of her and they lay on their backs, side by side, barely moving. Audrey fumbled with her nails while Seymour drummed his fingers against his stomach. They could cut the tension with a knife.
"Seymour", she started but didn't know exactly what she should say, "I am so sorry. I-I don't know what came over me! I never use language like that!" For the first time since they'd gotten married and embarked on their shared life together, Audrey felt unclean. Dirty. It was a feeling that was far too familiar to her but also one that she was just beginning to forget. It had all come flooding back to her in that moment.
"Fuck!" Seymour suddenly exclaimed, causing Audrey to flinch a little. "Fuck." He said it a little quieter the second time around, not wanting to startle her again. He rolled onto his side so he was looking into her eyes, "Fuck, fuck, fuck. See? Now we're even?" It was enough to make her smile. "Well, actually I said it five times so I have an even bigger potty month than you do, Mrs Krelborn!" And that was enough to elicit an enormous giggle.
