Sherlock just sat there for a few vital seconds. John couldn’t tell if it was disbelieve or if he was fighting for self-control. No matter, his parents rattled on....
“And our seats are up by Mycroft and Greg since we see even less of them than we do of you two. It was so good of you boys to invite us in secret!”, Margaret said with a fond smile. Touching John’s face she said, “we really do have the best sons-in-law don’t we?”
Timothy, smiling broadly, said, “yes, we really do! We’ll be back later to talk!” And with a wave they moved back towards Mycroft and Greg.
John didn’t look at his spouse as he waited for the fallout. After a couple of seconds of silence, he finally gave in and turned his head.
Sherlock was sitting there, open mouthed, still stunned. Finally, he turned to his husband and said, “for the first time in my life, words fail me.”
John, sensing an explosion, tried to explain, “Greg and I thought it would be a nice thing to become closer as a family. Neither Greg nor I have family of our own (Harry doesn’t count), so we are adopting yours. And since we have so much to celebrate this year,” Sherlock glared at him, “with your brother’s marriage and your dad’s clean bill of health that we thought we’d do a family vacation.”
Before Sherlock could get a word out, John went on, “so you will be civil to your brother and his husband and nice to your parents! Or else!”
“Or else what?”, the detective said through gritted teeth.
“Well I really wanted to join the Mile High Club. And if you’re good, I’ve thought of a way to do it without getting caught.” Sherlock perked up instantly. “However, if you act like an ass, I’ll tie you to the bed in our cottage, make you watch me get myself off and leave you there. Erect and unable to do anything about it.” John sat back and picked up his book. “You decide.”
Sherlock looked at him in disbelief, “you wouldn’t!”
”Watch me. Pun intended.”
