Leonard wanted Sheldon to tell his mom. Sheldon was, well, opposed to the idea.
They were in bed the last time Leonard ever brought it up. Breathing ragged and knees weak, Sheldon was hardly in a position to disagree.
"Please, Leonard, I'll do anything," Sheldon begged.
"Tell your mother," Leonard replied seriously.
"But, I…" Sheldon started to say, as his body convulsed with desire. He was starting to doubt his ability to hold out, especially as Leonard was planning on withholding sex.
"You'll either do it or you won't, but I'm not going to stick around if you're ashamed to tell your own mother about me," Leonard answered.
"Fine," Sheldon huffed. Leonard continued what they'd been doing before.
Sheldon was nervous. His Texan accent always came out stronger than usual when he was nervous, or disturbed, or when Leonard did something amazing. His mother was due in an hour and all he could think of was the look of disappointment on her face when he told her. Penny sat next to him, rubbing his shoulders soothingly. It wasn't helping.
The door opened. His mother was here. She pulled him into a hug. He told her he had something to tell her, something important. She sat down in Leonard's chair, across from him. He was on the couch (0,0,0,0) and Leonard sat next to him. Penny was next to Leonard.
"I feel that you should be informed. Actually, we felt that you should be informed of the status of my relationships. I have found myself a partner and we are very happy together. Please, don't be mad," Sheldon said. His mother gave him a confused glance.
"What on God's Earth are you going on about Shelly?" his mother demanded.
"My relationship with Leonard," Sheldon answered confusedly.
"Well, if that's all, then what were you all worked up about?" she quizzed.
"I…you knew?" Sheldon questioned disbelievingly.
"Of course I knew. I knew that it was only a matter of time. You come out here and call me up, finally, saying you got a roommate that's actually going to stick around. Then, he comes out here looking for you when you run back home. I figured if he could live with you, he was already halfway there. Plus, you got this faraway look in your eyes whenever you talked about him. Honey, your friends knew, too. Everyone knew. Except the two of you, naturally," she explained. Sheldon clutched Leonard's hand in his own. He was amazed at how accepting his mother was being. "Now, if y'all will excuse me, I'm a little tired."
"Sheldon?" Leonard said quietly.
"I'm…in shock, Leonard," Sheldon answered.
"I know," Leonard replied, putting his head on Sheldon's shoulder. "I know."
