Erotica Sex Story: Chapter 13: The Good Old Nurse (III) - Watch as Sirius navigates his way through the Hogwarts of the old days and the new. The way to a man’s heart goes through his belly, and the way to a woman's heart goes through her cunny—Sirius chose to live by those ideas.

Immediately, she took off her white, substantial panties and Mary-Jane shoes, then climbed on the bed, kneeling over his legs, one knee on each side. She looked down at his face with some fear and doubt in her eyes, but she relented in her desire to help and sat down on his lap to pull down the last piece of cloth over Sirius’ body: his underwear.
“Oh!” She jumped a little when his hard, significant erection appeared, pointing straight up, swollen so much that it looked all red. “This is to help ... this is just to help you...”
Keeping things hidden, she scooted over and lowered her hips down above his pelvis, then covered everything with her airy dress, hiding the place where her womanhood met his male desire. She positioned herself easily and straight away lowered herself on his throbbing shaft.
“Oh!” Sirius exclaimed first as his sensitivity peaked.
The newfound arousal from the tightness that surrounded his dry knob seemingly made things worse and more painful. But then she went further down, taking more and more of him in, and her juices started to flow, lubricating him little by little.
It was so tight and warm that Sirius curled his toes and clenched his fists tight.
“Oh dear!” Madam Pomfrey was in no better shape, having to accommodate his girthy length. It felt like uncharted territory, and she had no clue if she could even take all of him in. She only kept her eyes closed, the nasty, intimate flesh of theirs hidden under her dress, and her teeth gritted.
But Sirius suddenly pumped his hips up, shoving in a little more than what she hoped for, all too abruptly. She felt pained and yet strangely warm and good even when squirming over him.
“Ah, ummm ... This is to help you-oh ... only!” She reminded him, but it felt more like self-assurance.
Sirius silently stared at Madam Pomfrey, coating his cock with her almost dry walls. It was so rough and rugged to squeeze in, but he was lost in lust. Her long, somewhat curly brown hair was slowly getting untidy, while her white, mature, round face was turning pink.
“M-more...” He groaned and held onto her waist with his hands. The multiple layers of her healer robes were annoying, however. “Ugh ... I need more.”
Madam Pomfrey helplessly tried to put more of her weight onto her hips and sink further down, but it was getting too painful. However, helping students heal no matter what was like her unspoken, unbreakable vow.
“Fuck!” Sirius cursed and gripped her waist tightly before pulling her body down and his hips up. Mercilessly, he pushed into the lovely matron of the school, exploring the sunken depth in her hidden core. So warm, so tight, he felt his cock twitching in excitement.
“Aaaah! S-Slowly!” Madam Pomfrey cried.
But Sirius was delighted for a different reason. “I feel so much better ... It’s working.”
Madam Pomfrey didn’t forget her role in that and quickly looked to the bedside table where she had placed the tray with medical supplies. She leaned forward on his body while Sirius’ member remained throbbing within her clenching depths.
“Hnngh ... drink this.” She picked a vial and poured the contents into Sirius’ mouth. “It will ... calm your heart—ah!”
Sirius swallowed the potion and pulled Madam Pomfrey further down on his body until he could feel her warm, tingling body on his chest. Her face so close to his, he licked his lips. “Forgive me, Madam Pomfrey, but I know what can truly calm me down right now.”
“Oh ... Wait!”
Ignoring Madam Pomfrey’s yelp, he hugged her body and turned around, pinning her down on the hospital bed, which made creaking, metallic sounds. He kept her wetness thoroughly spread with his unwavering cock, legs wide open in that heavy dress, as he looked down at her face.
“Again, forgive me...” He went down and sunk his face under her chin and licked her neck. He left no spot of her delicate skin while his hands fondled her mounds and glided into her depth below.
Back and forth, he soon got her tightness wet according to his need and earned her uninterrupted suppressed moans. With her head thrown back on the pillow, she tried to clench the bedsheet with her hands to control herself.
“This won’t do,” Sirius muttered and tried to take off her clothes, starting with the oversized apron. There were so many layers that it annoyed him to no end, but he still pushed through. Never once did he stop sliding in and out of her.
“Mr. Black, I’m only helping you ... this is not needed!” She tried to protest at his attempts.
Sirius continued and started removing her gown by lifting it up. “This is how you can help, Madam Pomfrey.”
“What if someone comes?” She tried to scare him.
But fear was the last thing Sirius felt at that moment. “Let them.”
At last, he got so annoyed that he ended up tugging down at the neck of her dress and savagely tearing it apart downwards, creating a wide enough gap to slide it further down from her arms to her waist, and then completely off after a short moment of pulling out.
It was cold, and Madam Ponfrey felt it all over her naked skin. Only her bra was the lone cover on her body now, which soon got pulled away violently too. As naked as Sirius, except for her knee-high white Victorian socks, she found herself squirming underneath him, skin to skin.
“Mmmmm ... slower...” she moaned as Sirius began rocking inside her, spearing her with his girth. It felt utterly full, and she could see herself being ruined with all that stretching.
Sirius took the sight of her womanly body in his eyes first. She was attractive and alluring. Her body was lithe, but her mounds were full and tight, jutting outwards with their pale brown, throbbing tips and sizable areolas.
Looking down, the view of his cock sliding in and out of her tight, hot pool of throbbing insides drew his pleasure out like a bee finally finding nectar.
“Ugh, ugh...” Sirius felt the urge to find release, but the strange Lust Potion seemed to have made it hard for him, prompting him to take a harsher pace and pound into her. He fucked her mercilessly while devouring her ample soft breast in his mouth.
“Ummm ... ah, ah ... Mr. Black ... oh, so...” Madam Pomfrey seemingly lost herself to his pounding, maintaining her spread legs with constant, long moans.
“Who’s there?!”
Suddenly, a groaning voice echoed from the entrance, followed by a cat’s meow.
Sirius heard it and felt his mouth going dry all of a sudden. Damn, Filch!
“Let me go, quick!” Madam Pomfrey cried.
But Sirius couldn’t possibly do that, not until his problem was solved, as he felt his cock was throbbing painfully harder any time he didn’t spear her pussy apart. So he quickly pressed his body down on hers and threw the blanket over themselves.
“Mr. Black, he wi—”
Sirius groaned and shoved his lips on hers, taking her by surprise and shutting her mouth for good. All her resistance melted away, and they silently heard the footsteps getting closer while their lips never stopped sharing the silky warmth.
“Errr ... Let’s go, Mrs. Norris. Don’t make noise.”
Sirius finally noticed the footsteps leaving and started to move again, slowly at the start, rubbing his entire body against hers, sliding in and out of her slick wetness with ease. The sudden kiss had turned into a full-fledged heated moment of sweeping searches in each other’s mouths.
“I really need this, Madam Pomfrey. Please don’t be mad at this,” Sirius suddenly commented and threw the blanket away. Then, while continuing to pump into her, he picked up his tie and tied her hands on the bed’s headboard. Then, using her own nurse cap cloth, he tied the other hand.
“W-What is the mea...”
