Sirius watched, smiled and waved as Lily and James drove away from the house into the sunset. As they disappeared, he went back inside. It had been a few weeks since they had brought Crosby home from the hospital and Sirius had gotten back into his old routine: lounging round the Potter house a lot of the time.

But this was the first time he had been left alone with just Harry, well, Crosby was there, but he's a baby, so he doesn't count.

He went into the lounge and saw Harry sitting on one of the couches, looking into the fire. He was holding Crosby, who was gurgling quietly in his arms, something they had learnt he did when he was contented, already earning him the nickname, puffskein. Harry was humming a soft tune peacefully and rocking him slowly, making his eyelids start to droop.

Sirius watched as Crosby fell asleep with no fuss or protest at all. Harry stood up and carried him upstairs, Sirius following. He put him in the crib and they watched him for a moment before leaving the room. Sirius put his arms round Harry who kissed him passionately and softly on the lips.

"You know what today is?" He asked and Sirius shook his head. "6 weeks." He whispered into Sirius's ear and gave it an erotic lick.

"You sure you want to?" Sirius said back and Harry nodded.

"Yeah, I'm sure." He said and kissed Sirius. He wrapped his arms round his neck and Sirius picked him up and carried him to his room.

"Let me be in charge today." Harry said and Sirius nodded and Harry kissed his neck and started fumbling with the buttons of Sirius's shirt.

Together the two made passionate, sweet love before they lay next to each other in the bed, Sirius's arms wrapped around Harry.

"Love you Sir."

"Love you too Har." Sirius replied, this time, having no trouble at all saying those words.

"Sirius. Sirius." A voice called softly and Sirius opened his eyes. He squinted and saw red and green. Immediately, he jumped up, terrified he had fallen asleep in Harry's bed. "Calm down Sirius." Lily said and he looked round, his vision clearing up to show he was on the couch in the Potter's living room.

"Oh, ok." He said and lay back down. Lily smiled at him. "You can go home." She said and he turned around to face the other way. "Or you can stay here, I take it that's what you are doing?" She said and he grunted in response.

Lily got up from the edge of the couch and went upstairs. She checked on Jack (who was happily dozing after James had just got him back from Remus) andCrosby and was about to go into James and her room when she stopped by the nearest door.

She opened it and went inside, looking over the sleeping form of her oldest son, he was shirtless but covered by the blanket from the waist down and his one arm was resting near his head while the other hung over the edge of the bed. She touched his cheek and he shivered, his breathing stopping for a second before resuming normally again. She took her hand from his cheek and put it in his hand. His uneasiness stopped and she held his hand in hers.

His eyes opened slightly and he smiled at her before closing them, though it was apparent that he was still half-awake. "Did you have fun with Sirius?" She asked and he nodded. "Good night my baby, I love you." She said and stood up to go but Harry squeezed her hand slightly.

"Love you too, mum." He said and she looked to see his eyes closed but a grin on his face. She kissed his forehead and left the room. If she had stayed longer, she might have found out that her son was naked under those covers, and had she asked what fun he had had with Sirius, maybe Harry would have been drowsy enough to tell her. And had it not been so dark, she would have seen the pair of boxers much too big to be her son's, lying at the foot of the bed…

If Lily had seen all of these things, maybe she would have been able to been able to the events that would tear her apart from her son for so long…
