When William had been nursing, John drank from Sherlock every 2-3 days. Once he was weaned, it became a lot less often . It felt good, but it did weaken him a little to be drained so often.

And yet, Sherlock was still excited at the prospect of being drank from again, even though it was going to be 8 months of pregnancy, and probably a year or more until the baby was weaned, so he would be slightly weakened for almost 2 years, but he didn't mind at all. He would do anything for John and his family. And he wasn't weakened much anyways. He could get away with drinking 1-2 times a week when pregnant, then it would go up when the baby was born.

Sometimes the drinking led to sex, or was sometimes they did it during sex. But most of the time, since William was a baby, it was just the short times when he was sleeping, when there wasn't time enough to do anything else.

"Of course." Sherlock said with a smile. "We want to keep the baby healthy." He chuckled and kissed John deeply.

"I think you should start now." His voice went into a low register. "And I think you promised me something earlier today, didn't you?"
