Severus stopped in the lounge doorway and stared in horror was he watched Remus look through the research he'd apparently left in plain sight on the coffee table.
"Lupin, why are you going rummaging through my personal things?" Severus was happy his voice sounded normal.
"I didn't know it was private. You often leave me things to read, I assumed that's what this was."
"Well it's not." How could he have been so careless? He had a plan. The potion was brewed, timed so he'd be ready to conceive whilst Remus was at his most amorous. He shivered slightly as he thought about how randy the approach of the full made the were.
"Are you seriously considering this?" Remus' brow furrowed.
"If you must know, yes."
"You might have mentioned it." Remus said slowly.
"I'm certain your Ms. Tonks never mentioned it before it was a fact. You married her fast enough once she did." Severus' had flew to his mouth. How could he have said that?
Remus' eyes narrowed. "What is this about Severus?"
His brain picked the wrong time to freeze up, he'd told the Dark Lord porkies for years and now here he stood speechless.
"Severus?"
"It was a way to kill two birds with one stone. I would like to be married and have a child. As a Gryffindor, I imagined that you married her because she was pregnant the same would be applicable to me." Severus raised his chin defiantly.
"Marriage?" Remus blinked rapidly.
"You might have heard of it, you were married once." Severus drawled.
"But you never…."
"It's been three years." Severus interrupted. "Not to mention all the time prior to your last wedding." He huffed. Their relationship had gone on much longer than anyone knew: before Remus teaching at Hogwarts, before Lily's death, before the Shrieking Shack incident.
Remus straightened and pressed his shoulders back. "Any time I even mentioned the word marriage you said it was for dunderheads and Gryffindors. In my sock drawer I have an engagement ring that I found in an antique shop in Glasgow. It's an emerald cut moonstone flanked by garnets. I had intended to ask you the question and give it to you two years ago during the celebration of Lupercalia. You told me that a couple that had just become engaged during dinner look as if they belonged in an asylum. I thought better of having my heart trampled and I let things go along as they were. Now, suddenly you want to be a mother and a husband?"
"You what?!" Severus sputtered.
"You heard me. If you don't believe me, go have a look for yourself. It's in the back my sock drawer on the right."
Severus deflated.
Remus touched his forearm. "Talk to me, please."
Silence followed.
"Please?" Remus intoned.
"I wanted you to acknowledge me to the world. Stupid, I know. And the older I get the more I recognize that I have always had the need to protect.." He paused. "And in my own way nurture children. I want what you have with Teddy." He stopped and looked down at his shoes.
"Severus, you do have what I do with Teddy, but if you'd like a child of your own as well I'd be happy to help. You could adopt, or there is surrogacy."
"Oh please Lupin, could you imagine I'd ever be satisfied with how some young chit was carrying our child?"
Remus threw back his head and laughed. "No, I guess I can't imagine that. If you want to go through with this I'd be thrill to have another child." He paused. "Two or three even."
"Lupin, we're talking babies here not a litter."
Remus chuckled. "So when was this plan to be set in motion?"
Severus looked away again and muttered "Tomorrow."
"What was that?" Remus asked.
"Tomorrow, so I might take advantage of your appetites during before the full…"
"And…" Remus prompted.
"I believed whilst you were busy rutting you wouldn't notice any subtle changes that…" Severus coughed. "That the potion might produce."
"I see. Well, then you'd best find your dress robes and as soon as Teddy is up from his nap we'll go up to the castle and find Minerva. I don't believe the Wizarding World ever revoked the marriage laws of Gretna Green and we can probably be wed before teatime." Remus dusted his hands off. "Now, I have to go buy something for appropriate for Teddy to wear to witness his parents' marriage. And you might as well that that potion of yours, as I intend to fuck you most thoroughly after Teddy goes to bed tonight."
"But Lupin, I haven't…."
"You haven't what agreed to marry me, carry my child? It was your plan entirely. I am simply implementing it."
"But Lupin…"
"Also, I imagined after you're completely shagged out I am going to have to spank your lovely arse. This subterfuge is really too much, Severus."
At the thought of the spanking Severus' prick filled. He recovered slightly from the blood rushing to his loins and stood tall. "I am a Sytherin, Lupin. Head of the Slytherins in fact."
"Well, Head of the Sytherins be prepared, by the time I get back we'll have seventy-two hours for a honeymoon and I believe that coincides directly with the maximum efficacy of your potion. If that literature is to be trusted." Remus waved at the papers on the table. "I have no intention of letting you out of bed until we have achieved your desired result. With any luck you'll have brewed the potion improperly and I'll have every excuse to repeat the process over and over."
Severus' prick was fully hard against his belly. "Not bloody likely." He said haughtily. "But I understand pregnancy hormones do make one more randy and your attentions might not be unwelcome." Not that they ever were. His heart soared. He was going to get exactly what he desire for a change.
Remus turned back in the doorway. "And don't think about wanking while I’m gone. I want an untouched virgin on our wedding night."
Severus prick throbbed. "But you did it…"
"I didn't know we were getting married today, besides one of us should have some experience." He winked.
