Sirius didn’t want to waste his day at home, not when Walburga constantly watched him with a suspicion-filled gaze. To act like a pureblood supremacist and a closet Slytherin wasn’t easy for him since he had to control his unconscious thought process. The free bird had to be caged.
He wore his usual leather jacket, got a helmet, and took out the old 1959 Triumph Bonneville T120 motorbike he owned. It wasn’t the best or the most modern, but Sirius loved it for its uniqueness.
He knew Lily lived in Cokeworth, in the Midlands. It was a good long ride from London, but his bike wasn’t ordinary. It could fly, and since he headed out without a sidecar, it was even faster.
So he took off not far from his home and flew northward toward the small town. He was fast, and within an hour, he flew over the town that seemed colorless, quite a depressing place to live. It almost reminded him of 12 Grimmauld Place. The various lined streets with bricked buildings and a distant disused factory. It was a perfect place to call haunted.
Which one was her house? All these buildings look identical. Sirius, with annoyance, looked around for a sign. Most homes were empty anyway, so he hoped to find some light or a sign.
That one only has man’s clothes drying. That one’s too unpleasant ... Aha! That must be it! Sirius noticed a Hogwarts uniform drying up and made his way toward it.
Doing his best, he landed the motorbike without making too much noise and stopped in front of the building. It was a twin-story cul-de-sac home, so he went ahead and knocked on the plain-looking door, seemingly looking out of place in that dirty brick structure.
Soon, the door creaked open, and a red-haired woman peeked out. She looked thin, maybe in her forties, with the same beautiful emerald eyes as Lily. Old, but she was still quite a looker.
“Yes?”
Sirius, being the old-fashioned man he was, greeted her like one, “Good evening, Mrs Evans. I’m Lily’s friend from school. Name’s Sirius—”
“Black!” Mrs Evans completed his sentence, her face full of smiles. “Lily talked about you and others. Why don’t you come inside, dear? I’m almost finished cooking dinner.”
He smiled and presented her with a cardboard box. “Thank you for inviting me in, Mrs Evans. I got this apple pie on the way. I hope it’ll taste good.”
Sirius lied. He had just picked it up from the kitchen in his house. Kreacher was going to throw it out anyway since no food was kept for more than a day at 12 Grimmauld Place. It was too beneath their pure blood.
Mrs Evans giggled and took the box, “What a sweet young man. Please come in, and Lily is upstairs in her room. Why don’t you go and chat with her while I finish cooking?”
Sirius nodded and followed her in. Though when he looked at Mrs Evans from behind, she almost reminded him of Lily, but just a little more on the curvier side, with a strange mature allure to her.
Must have been quite the looker in her youth. Now I know how Lily turned out so well.
“The door is on the left.” Mrs Evans told him as they arrived at the stairs. “I’ll bring you some snacks in a jiffy.”
Sirius sighed in his heart, liking the woman since his mother never even talked with him that nicely. Nodding, he just went up the stairs and reached a short hallway with doors on each side. One was decorated to the brim with stickers, posters, or some other girly things. While the other was entirely empty and plain.
It must be hers. Sirius knocked on the plain door.
He waited, but minutes passed, and nobody opened the door. So, he just turned the knob and walked in. Surprisingly, it was empty, and the room looked quite ordinary, without much taste. He noticed a big bookcase with many magical books, and a study table with a book about potioneering open.
“Just come in, Mum. Why were you knocking—”
As Sirius surveyed the room, he noticed a small door open at the corner of the room, and Lily was walking out. Her body was covered with nothing but a single tower, covering her bust and her intimate parts. Her long legs were bare for his eyes to feast upon. Her pale skin with freckles in some places looked as delectable as he remembered. Her wet red hair cascaded behind her back as well, making her face stand out—beautiful was an understatement in Sirius’ eyes.
“Don’t scream!” Sirius yelped before Lily could react.
Lily’s face turned a little furious and reddened. She covered her breast despite it being covered already. “H-How did you get here? Why are you here?”
“Firstly, your mum let me in. Secondly, I was worried about you. You’ve been ignoring me for almost a month in school. I wanted to talk to you, Lily ... I thought we were friends.” Sirius stepped closer to her but held back when she retreated.
Lily scoffed, “Friends? What kind of friends fuck like animals?”
Sirius’s brows rose, as he knew Lily never used such harsh words, unless...
“You’re angry with me? What happened? If you don’t tell me, I can’t fix it.”
Lily glared at him. Her green eyes seemed red at that moment. Losing her shame, she strode forward and punched Sirius in the stomach, even though it did nothing. “You! ... I’ve missed my period, Sirius! I’ve missed my bloody period ... Do you know what that means?”
“James?”
“You!” She exclaimed and punched his stomach again. “It can’t be him! It couldn’t be him ... He’s too sensitive down there ... He ... He finishes before we can even do it properly. He’s big, but it’s ... useless...”
Sirius frowned, feeling a bit awkward, “I didn’t need to know that about him, but I understand you. So, what’s the plan? Do you need some materials to make some potions?”
“It’s too late for that, it’s been days...” Lily almost had a crying face. “It’s all your fault! You always finish inside.”
Sirius spread his arms, feeling unreasonably accused, “I always asked where to, and you always let me finish inside—How is that my fault?”
“You!” She glared at him and walked over to look out from the window. She rubbed her face frustratingly. Her breath was ragged, clearly angered, and in much stress, “I’ll have to go to muggle hospital for a checkup.”
She must have been scared to death these past few days. No wonder she avoided me.
Sirius felt somewhat guilty and wondered how he could help her. He honestly had no idea since even Lily couldn’t think of a potion to solve the issue. So, he tried to do the next best thing and console her.
“Lily ... No matter what, I’m with you. I’ll take you to the muggle hospital,” He got closer to her. “I’d have said the same thing if you had told me about this in school. It was a mutual thing between us. We’re close friends—I won’t chicken out now.”
Sensing her shoulder relaxing, Sirius stepped forward. He tried to comfort her by placing his warm hands on her shoulders and looking down from over her right shoulder.
Lily tensed for a split second but then relaxed. Instead of removing his hands from her bare naked shoulder, she touched them, placing her palm over them.
“Why did you look so annoyed all the time in school?” Sirius asked her.
Lily sighed and tiredly let her head fall forward. “I love James ... But he’s not very ... He tries to make up for it with his fingers, but he doesn’t know how to. He ends up hurting me, but to keep him happy, I just act like I enjoy it.”
Sirius sighed, wondering how the hell his good friend turned out like that. But it made sense now why James always looked happy while Lily was disappointed. The man was living in an illusion.
“He wants to marry you,” Sirius revealed something that had been eating him inside. “He told me a few days ago, and ever since, I’ve been losing my mind. On the one hand, I enjoyed it with you, but on the other, I feel guilty.”
Lily straightened her back and turned around. She soon found her peaks pressed on Sirius’ chest as she looked up to match his eyes, “I know you’re not a bad guy, Sirius. I enjoyed my time with you. To be honest, I’m even more afraid now, knowing I might actually agree to marry James.”
Sirius abruptly chuckled, “Aren’t we too young to be talking about marriage?”
Lily smiled and rolled her eyes, “Why is the ‘Lone Wolf of Hogwarts’ so worried? Are you afraid I’d tell James before we get married? Don’t be silly. I’m not that naive ... not anymore, anyway. You made sure of that.”
“Who gave me such a lame title?” Sirius chuckled.
“The day-dreaming second and third-year girls, who else? They’re dying to see what’s under your robes...” Lily smirked.
Sirius licked his lips as he felt them go dry. He took a deep breath and glanced at her breasts pressed onto him. He could make out the cleavage. It aroused him, and his erection responded quickly, immediately bulging near her stomach. He was sure she felt it too, “I was wondering if you still wanted this teacher to give you another lesson? Maybe a parting one?”
Fuck! What the hell am I saying? I came here to end this.
Lily’s heart beat much faster, as if she was going to burst into rage at any moment, “After everything, you’re still asking that?”
Sirius nervously released her waist. “Sorr—”
“Ummmmh...!”
Lily jumped, slammed her lips onto his, and like a hungry lioness, invaded his mouth with her firm, smooth tongue. She grabbed Sirius’ head with both palms and leaned in to kiss him harder. Continuously, she hummed under her breath as if saying something. But her lust was so out of control that she refused to stop kissing and speak clearly.
Shocked at first, Sirius soon wrapped his arms tightly around her and kissed her passionately. He explored her warm tongue as well, turning and twisting around her wetness, tasting her quite literally.
“T-Teach me ... Umh...” Lily attempted to speak in between. “Sirus ... I w-want y-umm-ou to...”
For a split second, she pulled back her face and glared into Sirius’ eyes fiercely. “Teach me everything you got.”
Sirius was rock solid by then. He slid his hands down and held onto her firm, shapely ass. He picked her up. Lily responded in kind and lifted one of her legs to his side. With that, Sirius felt her towel rise, and he took the chance to hold onto her bare soft behind. She felt smooth and warm, and he enjoyed kneading her ass. Slowly, he brought his fingers closer to her other hole and began to tease it with one finger. Lily moaned onto his face and began licking his neck after exploring his mouth. Her red hair twirled around wildly. Her lithe body was perfect to hold as she easily reached all over his face and neck to kiss or bite.
Sirius also kissed her neck the entire time while kneading her back. But eventually, he felt she was wet enough and decided to remove the towel entirely and pushed her onto the bed without holding back.
Knock! Knock!
“Dears, I brought snacks,”
“Fuck!” Lily cursed, a wild and rare sight. She immediately jumped off the bed and ran into the bathroom again. By the time the door opened, it was just Sirius and his painful erection that he forcefully clenched between his thighs to hide. Sitting on the bed while crossing his legs, he acted like there was nothing wrong.
Mrs Evans walked into the room, her face full of smiles as usual, “Have some orange juice and biscuits.”
“Thank you, Mrs Evans,” Sirius acted normal and went up to eat some. “Lily is in there.”
Mrs. Evans giggled as if she suspected something, and left the room. “I’ll call you two down when dinner’s ready.”
Sirius waited until she went down the stairs before sprawling to his feet and locking the door for good measure. Then, he began taking his clothes off because it was getting damn hot in there. “She’s gone.”
Clack!
The bathroom’s door knob turned, and it opened with a creek. With a soft giggle, Lily’s long, smooth legs came out, and surprisingly, the towel seemed missing. After that, she walked out confidently but with her eyes closed. There wasn’t a single piece of cloth covering her body.
The delightful sight made Sirius hungry. He tried to plant that image in his mind, observing her from head to toe and savoring her. The blushing, oval face with thin smiling lips. Her supple body with light curves, and her perky twin peaks and beautiful pink tips with small areolas. Looking below, her slightly wider hips only enhanced her alluring charm; the thin trimmed line of her dark red pubes was sexy. And the heart-shaped gap between her thighs and slit was—hypnotizing.
Sirius whistled, “Good heavens, that’s a sight I can never get bored of. But why don’t you open your eyes too?”
“What do you m—”
Lily looked and kept on looking. Right on her bed, Sirius was lying back, resting on the mound of pillows. Completely naked, his hard erection standing upright, stiff, and as if calling her closer with each pulsating throb. Its deep pink tip was swollen, almost gleaming under the light.
Beyond that, she couldn’t help but bite her lips. The sight of Sirius was comparable to something wild. His shoulder-length curly hair, the various lockets around his neck, and the tattoos. At the same time, he wasn’t bulky and yet muscular and tanned. His broad shoulders, strong chest and visible abs.
However, what aroused Lily, to the point she felt her warm folds going damp, were the light hair on Sirius’ chest and legs, while his member rested in clean. He looked like a ‘man,’ and for now, this man was hers.
