"Lily, " Sirius drawled as the door swung upon. "How lovely to - hear you."
Lily closed the door behind her, leaving her alone in a room with her husband's best friend.
"Please don't tell me I have to listen to your stale humour the whole time," Lily said sharply.
Sirius laughed. "I can't promise that."
"Promise that, and I might let you take that blindfold off," Lily said, walking over to stand above Sirius.
"To see you in muggle pyjamas?" Sirius asked.
"If you must know," Lily said, "I'm wearing lingerie right now. James' favourite."
"Let me guess," Sirius said. "Red?"
Lily shook her head, then realised such a gesture was pointless when talking to a man blindfolded. "Wrong."
"Green?"
"White," Lily said. "Innocent. Pure. Virginal. I enjoy the irony of it."
Sirius laughed, a hearty laugh, tossing his head back. Lily took a moment to admire the way his dark hair tumbled over his bare shoulders.
"Irony?" Sirius asked when his laughter subsided.
Lily knelt in front of Sirius, bringing her eye-to-eye with his muscled chest, and the trail of hair that ran from his belly button down to the band of his boxers. "Yes, well - nothing innocent will be happening tonight."
There was a moment of heavy silence, as Lily considered what she was about to do. It had been James' idea, from the start - if anything, she'd moderated it. Toned it down. James had suggested a threesome with Sirius, no holds barred. Lily had worried that he would become jealous, seeing another man - even one he trusted so implicitly - with her. So she'd suggested a trial run.
She would suck Sirius' cock. James would watch the memory in a pensive, and see how he felt. She'd taken steps to limit the risk. She would not be nude in front of Sirius at any point, and he would be blindfolded the whole time. He was not to touch her, and she was not to put her lips anywhere but his cock and the skin near it.
But, as she hooked her thumbs into the band of Sirius' boxers, she didn't feel like the risk was contained. Already, she was getting wet - and, if the bulge in Sirius' boxers was any indication, she wasn't the only one turned on by the sheer taboo of what was about to happen.
Sirius lifted his hips, and Lily peeled his boxers down. His cock sprang free right away, and she felt her breath catch in her throat at the sight. It was hard already, six inches at the very least and girth too.
"Lost for words?" Sirius asked smugly.
"We both know you're the one who feels the need to fill any silence," Lily said, brushing her fingertips along the inside of Sirius' thigh.
Whether it was her words, or her touch, Sirius fell silent.
Lily wrapped her fingers around Sirius' shaft, finding him hot and firm to the touch. His hips twitched, slightly, almost imperceptibly, but Lily noticed. This was her favourite part of giving a blowjob - the power she had over the man. She gave Sirius' cock a slow pump in her hand, feeling his soft skin glide over the iron hardness beneath.
"Just going to tease me?" Sirius growled.
Lily laughed, and stilled her hand. "If you think this is teasing, you're in for a long night."
Sirius huffed, and Lily pulled down on his shaft, peeling back the foreskin from his tip. She leaned in, and gently, so gently, flicked the tip of her tongue against his slit.
Sirius moaned and his hips bucked, trying to force himself between Lily's lips - but she was expecting it, and moved back with a casual smirk. "Be patient."
She gave his cock two slow strokes, then leaned in to lick at his tip again. This time Sirius stayed put, his fists clenching the bedsheet with the effort of it.
"Good boy," Lily purred.
She swirled her tongue around the entirety of his tip, and pulled back to see precum leaking from the slit. She licked her lips, then leaned in and flicked her tongue in to taste him.
"Lily," Sirius groaned.
"Not a patient man, are you?" Lily asked, giving Sirius slow, lazy strokes.
"Not at all."
Lily laughed softly and leaned in to place small kisses down the length of Sirius' cock. She felt him squirm, and rewarded him for resisting by sucking gently on one of his balls.
"Please," he panted.
"Please what, Sirius?" Lily asked.
"Please suck my cock."
Lily licked her way back up Sirius' cock, and wrapped her lips around his tip. She sucked hard on the tip, hollowing out her cheeks, making Sirius moan her name.
She released him from her mouth with a quiet pop, and smirked up at him. "I didn't think it would be this easy to make you beg."
Sirius grunted something unintelligible, but Lily couldn't blame him. The situation was driving her crazy with lust too - her panties were soaked through, and her wetness ran down the insides of her thighs
Sirius interpreted Lily's pause for thought as further teasing. "Fuck, Lily, please, I need this."
Lily licked her lips. "Need what?"
"Need your lips around my cock," Sirius moaned. "Please."
Lily obliged. Her hand slid down his length to grip his base, while she leaned in and closed her mouth around him. Where before she'd taken only his tip, this time her lips continued downwards, taking one inch, two, three, four. She paused, then pulled her lips back. Slid them back down. Her head bobbed up and down on Sirius' cock as she pushed herself to take more each time. She got to five inches, six, and - with one final effort - took his whole cock into her mouth. She pulled back, slipped him from her mouth.
"How many girls can do that, Sirius?"
"I'm not thinking about other girls right now," Sirius groaned.
The words hit Lily like a spell, washing through her, giving her goosebumps across her body. Here was Sirius Black, one of the most desirable wizards in Britain - thinking only of her.
She leaned back in, wanting to keep that attention solely on her. Her lips slid easily up and down his cock, spit leaking from her mouth to leave his shaft shining and slick. As she sucked his cock, her hands roved over her own body. One slipped into her bra to knead her breast, while the other slipped into her panties. Her fingertips circled her wet clit, making her moan around Sirius' cock.
"I know what you're doing," Sirius moaned.
Lily popped him from her mouth. "Giving you the best blowjob you've ever had?"
"Touching yourself."
Lily's hand stilled in her panties.
"I can hear how wet you are. Smell how turned on you are," Sirius said.
"Maybe," Lily said weakly.
"I'm sure that lingerie's getting in the way."
Lily bit her lip. Sirius was right - the tight and lacy cloth wasn't giving her the best angles to touch herself. And what was the harm in losing it? Sirius was blindfolded anyway. She clicked her fingers, and suddenly she was naked. She felt cool air press against bare skin where she'd been covered just moments ago - but she couldn't kid herself that that was why her pink nipples were hard as diamonds.
Sirius' cock was in her mouth again, and her fingers were slipping into her pussy, gliding in easily with how wet she was. Sirius' moans joined her own, and she began grinding down against her fingers; leaning forwards to get better leverage. Her bare tits brushed Sirius' knees.
Sirius gasped.
And then his hands were on the back of her head, pushing her down. Inch after inch of cock slid into her mouth, pinning her tongue down, until he bulged in her throat. She gagged around his cock, spit dribbling from the corners of her mouth, for several long seconds until he pulled her head free.
"Sirius," she gasped.
"Tell me you didn't like it," Sirius said.
"I - I didn't say you could do that," Lily said instead.
"Tell me you didn't like it," Sirius said again.
Lily looked from Sirius' wet cock, up over his muscled chest, to his smug grin. "I can't," she admitted.
"Ask me to take charge," Sirius said.
"Please," Lily said, grinding down on her fingers. "Take charge."
"What were those silly rules?" Sirius asked. "The blindfold stays on, and I don't touch you?"
A flicker of worry passed through Lily. "James' rules."
Sirius snorted. "James knows me. He knows I haven't followed a rule in my life."
Lily laughed. "Not one."
Sirius reached up to his face and pulled off the blindfold.
Lily looked up at him as his eyes devoured her. She could feel his gaze burning into her, starting with her flushed cheeks, and moving down. The blush that spread to her chest. Her perky tits, the hard nipples that capped them. Her stomach. Her pussy, pink, shining wet, spread around two fingers. Her thighs, wet too.
Sirius' grey eyes were dark with lust, and he moved suddenly, pouncing on Lily, pushing her down onto her back. Her tits bounced with the movement, and her wrists ended up in his hands, pinned behind her head. His cock brushed the inside of her thigh, and then his tip was brushing against her clit.
"Sirius," Lily moaned. "Fuck me."
Sirius ground his hips forward, and his cock rubbed along the length of her pussy.
"Please," she begged.
Sirius shifted, and now his tip was lined up with her entrance, pushing forward at the slowest, most agonising of paces.
"Fuck me hard."
Sirius leaned forward, his tip parting Lily's lips now, sliding inside of her - just the tip, not even an inch. His chest pressed down against hers, chest hair tickling her nipples, and his mouth found her neck.
She moaned beneath him as he kissed and sucked at her neck without mercy. She ground her hips up against his cock, feeling the first inch slide inside of her, tantalising, making her even more desperate to feel the full length of his cock inside of her.
"I'm going to fuck you so hard, Lily," Sirius whispered in her ear.
"Yes."
"I'm going to fill your tight little pussy with my cock."
"Please."
"I'm going to have you begging, pleading for more."
"Anything."
"I know you can't wait to feel my cum filling you up."
"Now!"
Sirius laughed, then stood up - his tip slipping out of Lily as easily as it went in.
"Sirius - what?" Lily moaned
"I want James to be there," Sirius said. "I want him to hold you in place as I plough into you. I want him to fuck your face as I use your pussy. I want you to come undone between two cocks."
"I need you," Lily pleaded.
"Enough talking," Sirius said. "Come here and suck my cock."
Lily's body moved of its own accord, and she knelt before Sirius, taking him back into her mouth. She tasted herself on his cock, her juices, and greedily sucked every last drop off of him.
"You're going to go back to James and tell him you broke every rule," Sirius said, his cock throbbing in her mouth.
Lily moaned her agreement around his thick shaft.
"He's going to love it, and he's going to floo me to decide a time for us to use you together."
Lily sucked hard and fast.
"I'm going to cover you in cum."
Lily moaned.
Sirius' cock twitched in her mouth, and suddenly he was pulling her head back. His cock pulsed in front of her, and hot sticky cum shot from his tip, splashing against her face. He kept on cumming, splashing strands of cum all over he face, neck, and tits - which ran down her body, in a river between her tits, down to her pussy.
She looked up at Sirius, and found him smirking down at her. "I'll keep the lingerie. You can have it back once James and I have fucked you senseless."
