prompt #48, "I bet you can't go 24 hours without cussing." (this one has Sherlolly too lol)
"Bloody hell," John muttered.
"Daddy's upset again," Mary told Rosie who was in her arms. John turned to see his wife giving him that scolding look.
"What?" he asked.
"I bet you can't go twenty four hours without cussing," Mary teased.
"I can too," he argued.
"Alright, so if I win, you have to watch Rosie while Molly and I have a girls' night," Mary told him.
"Oh? And if I win?" John questioned.
"I'll try that new idea of yours in the bedroom," she encouraged.
"You're on," he challenged.
"Three phone calls with Sherlock and not one cuss word uttered," John said smugly. "I'm going to win this for sure."
"Mm, nope," Sherlock grinned from the sitting room, Molly by his side.
"When did he get here?" John asked.
"Oh, I invited him and Molly for dinner," Mary smiled. She was going to win no matter what it took. They never established any rules against playing dirty.
"Oi, that's not fair," he complained.
"Yes it is; we never established rules," Mary smirked. Sherlock chuckled as Molly stifled a laugh.
"So, I have an announcement to make," Sherlock told them at the table. "Well, aside from the fact I may have finished off your carton of milk."
"Why you-" John stopped when he noticed Mary's eyes on him.
"Anyways, Molly and I are engaged," he smiled.
"It's true," Molly confirmed as she flashed the engagement ring.
"What!?" John asked in disbelief. "You're not even dating!" Mary laughed. "Are you not seeing this, Mary? Sherlock Holmes is engaged! That doesn't happen for real!"
"Yes, I see but that's not why I'm laughing," she continued. "I already knew they were dating! Molly told me. I thought Sherlock told you."
"I knew I forgot to tell you something," Sherlock mused.
"YOU COCK!" he shouted. "You bloody cock!"
"And Mary wins the bet!" Molly announced as she gave Mary a high five.
"Oh, fuck," John groaned as everyone laughed.
