Investigation of Passion ch.9

"That wasn't okay," Hermione said.

Harry frowned, watching her slip back into her jeans.

"It wasn't entirely planned," he said. "Besides, it was your idea to give Fluer a show."

"Harry!" Hermione snarled. "You... you came inside me."

She folded her arms and stared at the floor with a worried expression.

"Listen, I'm sorry," he said. "Are you on the pill?" Hermione shrugged. "Yeah. But that's not the point. Never... I mean... That was my first time."

She looked up and met his gaze. "Mine too," Harry said.

"I know that," Hermione said. "But for a girl, it's different."

"What do you mean, you know?" Harry asked. "Did you just assume I was a virgin or something? And how is it different for a girl?"

Hermione smiled, apparently amused by his irritation. She shrugged and started fixing her hair.

"I guess we should get going," she said. "I need to check in with Fluer. Listen, what just happened between us... Don't make a bigger deal out of it than it is, okay?"

Harry hadn't even thought about making it a big deal, let alone a big one. He nodded, trying not to think about Hermione as he watched her pull her blouse over her chest. He managed, but instead, he ended up thinking about his stepmother.

He hadn't found any evidence that she was the woman from the recording. And for once, it didn't bother him. Now it seemed a bit ridiculous that she was secretly a porn star on the side. He was ready to let it go.

Harry got up from the bed and winced, feeling a painful cramp in his right thigh muscle. He tried to stretch his leg but to no avail. The position he'd been stuck in while trapped in the closet had apparently triggered something unpleasant in his muscles.

"Are you okay?" Hermione asked.

"I'm fine," Harry replied. "Just a muscle cramp." The walk home was excruciating. Harry said goodbye to Hermione as they passed her house, then went inside and headed upstairs. He struggled up the last few steps and collapsed onto the bed, grimacing at the muscle cramp that refused to ease.

He spent the next few hours in a state of agony, unable to move freely. His stepmother came home early, and he heard her humming as she set the shopping bags on the kitchen table.

"Harry?" she called. "Are you home?" "Yeah," he groaned.

"Can you come down and help me bring in the groceries?"

"I... hurt my leg," Harry said. "I'm not sure what's wrong."

He heard his stepmother hurrying upstairs and saw her in the doorway moments later. She was wearing the same outfit he'd seen her in earlier, a pink blouse and gray skirt, but without the heels. She winced when she saw him, her eyes filling with concern.

"Oh, you poor thing!" she said. "What did you do?" Harry hesitated. He hadn't taken the time to come up with a convincing explanation. He decided to go with the truth, or at least a version of it with some details omitted.

"Hermione and I went on an adventure earlier," he said. "And I kind of... hurt myself while we were doing something."

Bellatrix slowly nodded, a familiar smile playing on her lips.

"Right," she said. "I'm glad you two are spending time together in person. Even if you're being suspiciously vague about it."

"mom..." Harry said.

"It's okay, sweetheart." She walked over to the bed and sat beside him, planting a kiss on his forehead. "Where does it hurt?"

She placed her hand on his calf, over his jeans. "The other leg," Harry said.

"Here?" His stepmother touched the other thigh. "It's... higher up."

"Here." Her voice became soft, almost unsure, as she moved her hand further up his leg, caressing his thigh. It tickled him a bit and aroused him, causing him to blush.
"Yes," said Harry. "It's a bit of a strange place, but it’s tight."

"It’s not strange at all, honey," she replied. "I’ll handle the groceries and get dinner ready. Change into some shorts."

"What?"

"I’ve been taking massage lessons," she said. "I can relax your muscles and make you feel good as new. All it takes is some rubbing and caressing. It’s better than leaving you in your current state or stuffing you with potions."

Harry nodded, trying not to show how he felt. He wasn’t sure how he felt about his mom touching him like that, especially after he got so aroused watching the movie the previous night. This time, she wouldn’t mistake his erection for a phone, not if she was close and taking care of him.

"I’ll probably be fine," said Harry. "You don’t have to do anything special."

"Nonsense," Bellatrix said. "I insist."

Her smile was big and stepmotherly, and she was clearly more eager than Harry. She quickly left his room, humming as she headed back to the kitchen. Harry groaned and forced himself to get up from the bed and find a pair of shorts.

His leg was too cramped to move freely, so he waited at his computer while she prepared dinner. Hermione started her usual video game stream, and Harry watched it for a while to kill time.

His stepmother brought him dinner, spaghetti and meatballs. Harry ate at his desk, and she returned later to take his plate. She had changed into yoga pants and a loose t-shirt and had a bottle of baby oil with her.

"We can do this on your bed," his mom said. "It's not ideal. A real massage table has less give. But if I’m only working on your leg, it should be fine."

"Okay," said Harry. "Should I just lie down or...?"

Bellatrix sighed at him. "Let me make your bed first. Sweetie, you really should get into the habit of doing this yourself. Your room looks so messy when you don’t."

Harry rolled his eyes. "Sure, mom. I’ll do that."

She made the bed, and Harry lay down on the sheets. He felt a strange, unwanted sense of arousal as his stepmother took her position beside him. He chose a pair of gym shorts that exposed most of his legs. His mom frowned, reaching out and pointing at his thigh. "It’s this one, right?" she asked.

"Yes," replied Harry. "It just suddenly tightened up."

"What were you doing when it happened?" she asked.

I was having sex with Hermione, he thought. "We were walking around town," Harry said. "I think it was random."

"That’s unlikely," she said. "But okay. I should be able to loosen it up for you."

She leaned in close enough that Harry could smell her perfume. It always gave him a sense of nostalgia, reminding him of cuddling with her as a boy and sleeping in her bed on nights when he had bad dreams. Bellatrix extended her index finger and touched his calf.

"Does this hurt?" she asked.

"No," replied Harry.

"Let me know when it does," she said. They were both speaking in hushed tones now, as if the dynamic had fully shifted to the territory of a sensual massage.

mom stroked his leg, moving from his calf to his thigh. Each touch of her finger sent electric shivers through Harry’s body, and he already felt blood rushing to his penis. He forced himself to breathe and tried to ignore her gentle touch as she moved higher and began prodding the top of his thigh.

"And here?" Bellatrix asked.

"A bit," he replied.

"Alright." She let her finger wander, prodding the inside of his thigh, almost reaching the bottom edge of his shorts. His cock was only an inch or two from where she was touching, and Harry needed all his willpower to keep from getting fully erect.

"I’m going to start rubbing now, okay sweetie?" she asked. "I’ll start with just my hands and then add the baby oil if you need it."

"Okay." The word came out more as a pleading moan than actual syllables. Bellatrix slid the leg of his shorts up a bit, her hand briefly grazing his cock in the same movement. Harry felt himself getting even harder and grimaced, knowing it would be impossible to hide under the thin, loose material of the shorts.

It didn’t make sense to him. Between searching stepmother's room and the investigation they conducted in the real estate houses, it seemed almost certain that she wasn’t the woman in the recording. She was just his mom, normal, boring, and full of love and pride for her only son. How could his body react this way to her touch?

Bellatrix began kneading Harry’s thigh with effort. She squeezed with her fingers, rubbing and stroking the skin of his thigh and the muscles beneath it. Harry rested his head on the pillow. He looked down, wincing as he saw the visible bulge. Fortunately, his mom was too focused on his leg to notice.

"You have so much tension here, darling," his stepmother whispered. "Lucky for you, I’m here to squeeze and rub it all out."

"Lucky for me," Harry echoed.

She ran both hands over his knee, moving higher. He hoped he would get used to the feeling, but it still took his breath away. The pleasure of feeling her touch in a spot so close to his erogenous zone made his heart pound with anticipation.

Harry tried to control his breathing, but he felt shaky. He closed his eyes, melting into the sensation as stepmother squeezed and kneaded his thigh muscles. His shirt had ridden up a bit, and he could feel her breath tickling his stomach.

"You might have also strained your hamstring," mom said. "It runs from here..." She felt the spot just behind his knee. "Up to here."

Her hand slipped into one of the leg holes of his shorts, continuing until she was almost at his groin. Harry gasped in pleasure. He was now fully erect, but fortunately, the baggy shorts hid his arousal better than he expected, though he would be in trouble if she accidentally touched him.

The thought made him shiver with anticipation. Would it be trouble? If his stepmother accidentally let her fingers graze his dick? If she wrapped her hand around it and started stroking him? Drizzling baby oil over it so it was nice and smooth for her to pump with her soft, sweet hand?

"Harry?" she asked. "You’ve gone quiet. Are you in pain?"

"Oh! No, just... enjoying the massage." He felt his face flush with embarrassment. He had let his disgusting desires get the better of him again. His mom was doing him a favor. His thigh was cramped, and her only goal was to make him feel better. Why the hell did his mind have to go in a sexual direction?

"I’m going to shift so I can put more pressure on your muscle," Bellatrix said. "Sorry, this might be a bit awkward."

She climbed onto his bed, then onto him, sitting in a reverse position. Her crotch pressed directly against his erection, pinning it to his stomach. Harry let out a gasp. His jeans were thin, and mom's leggings were practical and flimsy. He could feel the warmth of her body and what lay between her legs against his hard cock.

"Here," Bellatrix said. "I can slide down a bit as I start pressing on your thigh. Can you help hold me in place?"

She pulled his hands onto her hips. The position was, ignoring the context and clothing, almost exactly what porn films call "reverse cowgirl." Harry winced, instinctively pulling mom back a bit and feeling the incredible sensation of her thighs and crotch pressing against his cock.

"You’re so quiet today, Harry," she said.

"Sorry." He pushed her gently forward, testing the limits of what he could get away with. It felt ridiculously good, and he regretted not being able to hurt his leg more often.

"Your leg is so tense," Bellatrix said. "The muscle is just hard and stiff. I’m trying to massage it out and get rid of the tension, but it’s not working."

"Go as hard as you need to." Harry let his hands slide up a bit, touching the bare skin under stepmother's shirt. He quickly pulled them back, not wanting to push his luck.
"This might feel a bit strange," she said. "I'll try to use my body weight to apply more pressure. It works better on a massage table. On the bed, it might feel a little... bouncy."

"Sure, go ahead," said Harry.

Bellatrix leaned back a bit and then shifted forward, pressing her fingers into his leg. It was a little painful, but that wasn't the only thing catching Harry's attention. Her butt lifted and then bounced back down on his cock. It sent a shiver of forbidden pleasure through him, taking his breath away. And his stepmother didn't stop.

She kept going, struggling to get her fingers deeper into his tight muscles, bouncing off son's cock in a steady, intensifying rhythm. She also made light murmurs of effort, each sound more seductive than anything Harry had ever heard.

He still had his hands on her waist, gently encouraging her each time her butt and crotch pressed closer to his cock. Well, it started as gentle. Soon, he was pulling her down, thrusting up despite the awkward angle with his erection pinned as it was.

"Exactly," said his stepmother. "If you can hold me like this, darling, I can hit the right spot."

"Oh..." Harry groaned.

He was too aroused to stop and think about what he was doing. It felt so unbelievably good, and she had given him permission to take a bit of control. Harry kept pulling her into him and rocking his hips, even as her fingers slowed their attack on his leg.

Then Bellatrix's phone rang. Harry controlled himself enough to stop. His head pulsed along with the blood in his cock, and he closed his eyes, feeling embarrassed.

"I'll keep going," said his mom. "Just let me take this. Hello?"

She pressed the phone to her ear with her left hand.

Her right hand continued to press into the muscle of Harry's thigh. The restriction meant she had to rock and bounce even more with each movement to get the same effect. Harry's breath caught in his throat. He was getting closer... How was that even possible?

"Uh-huh," said his mom into the phone. Her butt still moved along Harry's shaft, brushing his cock, up and down. "I can look into that. Just not tomorrow, I have the day off."

Harry tightened his grip on stepmother's waist. He was too aroused to stop what came next. He started thrusting into her, no longer trying to hide his movements. Bellatrix actually sped up her rhythm to match his, though he wasn't sure if she was aware of it or not.

"What? I'm taking care of my son right now. He hurt his leg."

Harry bounced her faster, the bed creaking beneath them, her butt making a sound like a pillow hitting something as it continued to bounce on his cock. He sped up even more, holding her so tightly that she would surely suspect something if not for the distracting phone call.

"Of course," said his mom. "Well, whenever he's ready."

Harry stifled a moan as he crossed the threshold. His cock exploded, shooting cum into his shorts. The material wasn't that thick, and some of his semen started to seep through, marking the back of stepmother's leggings.

Oh no. Harry blinked in the pleasure, the crazy, illicit pleasure. What had he just done?
