"Sirius, he loved you!"

"No Harry, but we did have a short relationship. That was the last time. Soon after that we broke up for he summer, I got a place of my own and James asked Lily to marry him. She accepted."

"But why did he leave you?"

"If only I knew. I have come to the conclusion that he didn't love me enough to give up Lily. Despite what you saw, they were quite a couple."

"Listen Sirius, when we were watching that, at first I was me watching it. But then I sort of became him, I felt myself in his position." Harry blushed. "Mentally as well as physically. He wanted to be with you. He felt like leaving you, he was leaving his own soul behind but something made him do it, I don't know what."

"Maybe he knew he was going to get such a sexy kid if he went with Lily." Sirius licked his lips and Harry laughed and blushed again.

"No, but maybe that's it. Maybe he wanted to have a kid…"

"Before you ask, time turners weren't around in those days." Harry knew his father had loved Sirius. He had felt it as though he had been James himself. Harry wondered if Sirius had ever got over that relationship. Maybe that was why Sirius was with him.

"I'm going to have a shower, thank you Sirius."

"Anytime."

The water flowed over Harry's bare skin as he turned on the shower and stepped into it. It was a big shower with a see through glass door, like a bubble. He began to rub shampoo into his hair. Why had Sirius shown him that? To make him jealous? Somehow that seemed unlikely. The shampoo was running into Harry's eyes. He screwed them shut and groped for a towel. Instead he found Sirius's warm chest. Sirius wiped the soap from Harry's eyes and held him close.

"I love you, Sirius said simply into Harry's ear.

"Me or James?"

"You." Sirius smiled down at him and kissed his neck gently, pulling him into a warm embrace as he did so. Harry collapsed against him, dizzy with happiness. He pressed his face into the warm hair on Sirius's chest and breathed in his musky scent. He was warm and safe. Sirius's mouth was by his ear and he was snuffling against it, making Harry giggle. Harry wriggled and Sirius pretended to nibble his ear very gently. It tickled. Wriggling and laughing, Harry tried to pull away, but all he found to step back to was the shower wall. Sirius poked his ribs and leaned forward again to devour Harry's ear. Harry slipped under his strong arms and out of the shower door. But the floor was wet and he skidded on his feet, coming closer and closer to the edge of the bath. He managed to stop himself just before he reached it, only to be thrown in unceremoniously by Sirius slamming into his back. He arrived at the surface to see Sirius's head bobbing above the water, laughing hysterically. Harry swam to the edge, laughing too and sat on the step in the water. He saw Sirius's face change from one of hilarity to one of intrigue. He swam slowly over to Harry; their eyes locked, and clambered onto him. He knelt up on the step, spread his thighs and slid forward onto Harry's lap, straddling him.

It was only then that Harry realised Sirius had a straining errection. His arms had been resting, stretched out either side of him on the side of the bath. Now he dipped then into the water and cupped Sirius in both his hands. Sirius gasped and then closed his eyes. He leaned forward and nipped Harry's ear and this time Harry did not laugh. He moved his hands faster, his fingers running up and down Sirius's length in the warm water, his thumb teasing and sliding over the head. Sirius grunted in appreciation into Harry's ear and Harry started to pump. Sirius drew in a long ragged breath, biting Harry's ear very hard and tensed in the water. A few seconds later he let it out again as he released into Harry's hands and the water. For a few moments Harry enjoyed the sight of Sirius sitting on his cock in the water and slumped helplessly against his chest. Then he raised himself out of the bath and sat on the side, his legs open, staring down at Sirius as he slid forward and rested his head on the side of the pool.

When he had recovered, he looked up and growled with pleasure at the sight of Harry's cock a few inches from his face. Sirius launched himself onto him and Harry lent back on the bathroom tiles, sighing as Sirius applied his mouth to his cock. Sirius was painfully slow. He slid his tongue slowly over the head, then took it away and licked gently at Harry's balls. Harry shivered with anticipation and Sirius slowed down still further, occasionally and lazily making darts at Harry with his tongue. Harry mewed with expectation and Sirius laughed. He slid his tongue firmly all the way up Harry's shaft and at last took him into his mouth. Harry moaned with the long awaited joy, but although Sirius had now taken him, he was still painfully slow. Sirius continued the torture for several minutes, reducing Harry to a quivering, panting wreck. Harry thought he might just come even if Sirius never got into it, the pleasure was so intense. Suddenly, as he thought this, Sirius moved. He gave no warning, but suddenly began moving his mouth up and down, over and around Harry's cock so fast that Harry felt his head spin and started to cry out.

"Oh god Sirius, yes!" he yelled, "Padf…Sir…ah…mmmmmm!" he moaned pathetically as Sirius lent him no mercy. He speeded up still further and Harry came, so intensely that he sprayed into Sirius, over his own chest and over the surrounding tiles, bucking franticly and screaming with the wonder of the release. Sirius moved up onto him, his eyes staring into Harry's glazed ones and kissed him, very gently. Harry's stiffened body relaxed and he began to breathe again, panting.

They lay in bed together, slowly running their hands over each other in the sleepy silence. I couldn't help staring at Harry for a minute. He really was very beautiful and sexy, lying there naked in the other man's arms. I longed to touch him but knew I could not. He was not mine now and I was not his. I briefly wondered if he missed me as much as I missed him but, looking at the happy sleepy smile that was playing on his lips as he fell asleep in Sirius's arms, I knew he did not. Sirius snored slightly as I watched and Harry's breathing became slow and regular. I cast a quick charm to check their aurors for any sign of alertness but they were clear. Both were dreamy and asleep. I crept towards Harry's side of the bed and slipped in behind him. Very slowly and gently I licked into his ear, murmuring,

"Happy birthday, Harry. I love you with all my heart. Forever. I slid out again and pulled my invisibility cloak. Harry mumbled my name sleepily, before falling silent. I looked him for the last time and left him to his quiet slumber.
