When Isabel woke up Mark was coming out of the master bedroom's bathroom having just showered. He had a towel wrapped around his waist, the rest of him damp and glistening. "Hey," he said.

"Last night," she started, but the emotions were still a chaotic mess in her sleep deprived brain. How could she articulate the mix of guilt, shame, and satisfaction she felt? She knew she should regret what happened, but she didn't.

After a few seconds where she didn't continue, Mark said, "What happened last night was me helping you through a bad situation. We don't ever have to talk about it, but I wanted you to know I think we did what we had to, and... and that's all it meant. And... it was a good thing. Right?"

"Yes. I feel the same," Isabel said, intellectually on board with what happened being an almost medical necessity. However, she was also aware that she was naked under the covers and that they had slept with their arms around each other all night. That had not been strictly necessary, but it had been wonderful.

He smiled, came over and kissed her on the lips. He said, "I love you."

She caressed his cheek to keep their faces close, and looked into his eyes. "I love you too."

In minutes he was dressed and gone to work. Isabel just lay in bed. Her mind replayed the events of the night before. Her brother had fucked her with a black rubber dildo while she jerked him off and ultimately let him cum in her mouth. Only the mix of penetration and semen seemed to sate the overwhelming lust that had come over her.

What had caused it?

Isabel got up and took a shower. Her pussy was a little puffy from all the pounding it had taken. She might have orgasmed four or five times in the span of a half hour. The intensity of the memory left her weak in the knees. She gently cleaned her crotch and then luxuriated for a long time, letting the hot water work into her muscles and release any remaining tension. She got out and stretched naked, feeling more comfortable in her body than she ever had before. Her hips felt loose as did her legs and back. Her breasts were slightly sensitive and she was overtly aware of smells and sounds and sensations. It all processed in her mind, making her feel somehow completely present.

I guess this is what they mean when they tell someone they need to get laid. Except I didn't really get laid, did I? We got each other off.

The morning got away from her and she rushed to make her appointed tour at NYU. It was a flurry of activity and the tour was of all the various buildings in and around Washington Square Park. It was nice, but she found it hard to concentrate. What had been important in her life just 24 hours ago, seemed inconsequential now.

Watching the other prospective students she had sudden intuitions about them. She knew who was having their period, who was stressed, who had smoked pot. She could tell which parents were tense or hung over, and she was sure one older dad had the hots for her even though he barely came near her.

What is going on with me? Is this connected to last night? Maybe I'm going crazy?

The tour stopped at a cafeteria and the tour guide said, "Grab some grub and meet here in a half hour." Which got Isabel thinking about what she'd eaten.

Last night they had pizza for dinner and then later she'd eaten one of the chocolate covered strawberries. She recalled the note from Aunt Maddie, who was desperate for cousin Linda and her husband to start making babies.

What a bizarre coincidence? It was a coincidence right? Might her aunt have laced the strawberries with some kind of drug?

She'd never heard of anything that could cause such a powerful reaction, but then again she was far from well versed in any of this. The limit of her sexual experience before the prior night was little more than kissing Jimmy McCalister in sophomore year, and a deep and abiding grinding based relationship with her Mister Bunny plushie. She had no idea what kind of drugs - legal or illegal - were available to excite that kind of physical reaction.

Isabel got into her own head as the day wore on. Even though she and Mark had cleared the air that morning, she didn't know what to expect as the truth of what they had done settled in. She returned to the apartment with a deep sense of unease.

Alone there, she tried to watch TV, but found herself far too distracted. She started to text Linda, but what would she say or how could she ask her if her mother had ever spiked anything else with "super horny drugs"? Besides, what she really needed was advice about what she'd done with her own brother - and there was no soul on Earth she could tell. She felt suddenly and painfully alone.

Isabel paced around the apartment, she nibbled at her fingernails, and finally went back outside to walk around the city. She needed to burn off energy. The late afternoon city streets were buzzing with people bustling from work - the sheer volume of humanity present in Manhattan was crazy. They all moved so fast and with such purpose, but she needed that motion as well as the presence of so many people while still being completely anonymous and alone. Her feet ate up the streets and avenues and she moved in a big circle, arriving back just as the sun was setting.

Mark was there and said, "I was worried when you weren't here, everything okay?"

"I really needed to clear my head."

He was quiet for a moment and then said, "Okay, yeah I get it."

She looked at him standing near the dining room table. He was in his work attire, a button down shirt and jeans. The barest hint of stubble had grown along his square jaw and he looked at her almost expectantly. The increased presence she'd been experiencing told her that Mark was anxious and more than a little focused on her. It was not like she could read his mind, but rather his emotions and even that was less reading and more of an inference based on all the things she could sense now, which normally would be beyond her perception. It's what she imagined animals did - why your dog was waiting at the door for you when you came home, or became excited when you were feeling worried or angry. She synthesized all of this to somehow know Mark had spent the day on edge thinking about her and the future they created through their actions the night before.

Despite all of that, there remained one burning question in her mind. Isabel said, "I wish I knew why I got like that."

"I've never heard of anything like it," he said as he lifted something up to his mouth. She saw with sudden dread that it was one of the chocolate covered strawberries. What's worse, he'd already taken a bite.

"What are you doing?" she said.

"I was hungry. We should get dinner."

She took a deep breath. "I just... I think those might have..."

He looked confused, "What? Linda said we could have them, right?"

Isabel shook her head. "Yes, but... I think there might be something in them - I thought about it all day. Why it happened, why I got like... that."

"Okay?"

"And the strawberries? The note from Aunt Maddie? Lynda said she wanted them to have a baby?"

He looked at the strawberry. "You think this made you want to..."

"Need. Need to. Mark it was so crazy intense. Seriously I had NO control. Otherwise..."

He put the berry down and came over to her. "Hey hey, just keep it in perspective okay? We did not cross the line."

Isabel thought of his cock in her mouth. "We for sure did."

"Okay, we crossed A line, but not THE line."

She shook her head, wanting what he said to be true, but not fully buying it yet.

"I know you felt what it was like, but you didn't see yourself, Issy. It was scary, so we had to do some stuff and yes it's weird, but you know if we hadn't done it..."

She said, "You're right. I know it's just..."

"We love each other. We would do anything the other needed. We have to be there for each other. That's what we did. I don't regret it. I won't. I can't." Mark gently took hold of her.

She met his eyes and felt that same thrill she'd felt seeing the effect she'd had on him the night before. He'd stepped up because he loved her exactly as much as she needed, but some part of her knew he was drawn to her in a way that went beyond brotherly love. She clutched him tightly in a hug. They stayed like that for a good while and then he said, "I am still starving though."

Isabel again spotted the half eaten berry. Okay, maybe if there was something funky with those berries he hadn't eaten enough. He was much bigger than her - if it was a drug it probably would be far less effective on him. And regardless, food would help.

They ordered Chinese takeout, again shocked at NYC prices, but their parents had given Isabel a good amount of money to tide her over for the week. So she paid and they dug into some Lo Mein and Sweet and Sour Chicken with ravenous abandon. She told him about NYU and the energy she loved about the Village.

Midway through dinner he seemed a little glazed over.

"You feeling okay?" She asked, but knew that something was happening - she could smell it on him.

"Yeah. Just tired. Did not get that much sleep last night," he said with a smirk.

"Sorry," she said.

He reached out and touched her. He was doing more of that, she noticed. Mark would place a hand on her arm or even her leg when he made a point. It was fine, good even, but she also noticed that whenever he touched her it muted that heightened awareness she was feeling, because it kicked off a response within herself. That awareness required her to be somewhat calm and him touching her was anything but calming.

Of course in a strange way, they were a LOT closer now and while she'd been afraid that it would ruin their relationship, now she saw that they seemed to have a way forward that strengthened their bond.

She rested her hand on his arm as she said, "We should turn in early."

Her hand stayed there and he slowly moved his hand to caress hers, but she could see he did it without thinking. It was a light touch where his fingertips traced circles on the back of her hand before roaming up her forearm. Then he took a deep breath and stood up. "Yeah. That's a good idea."

Mark leaned down and kissed her on the forehead, but seemed to linger and smell her hair a moment too long. Or was that her imagination. She stopped him as he moved to pull away. "Mark. If you feel weird or anything tonight, promise me you'll wake me."

"I'm okay, really."

"Sure, but promise."

"I will, but nothing's going to happen."

"Okay."

She wasn't as tired so when he went into his bedroom, she slumped on the couch and popped on the TV. Isabel channel surfed with the volume down low so as not to disturb Mark. She found a mindless soap-opera like teeny show. As she watched, the tension of the day drained out of her, and she drifted to sleep.

Mark dreamed of pussy. Every image from every porno he'd ever watched melded with the sight of his own sister's snatch from the night before: the puffy, darker labia, the tuft of hair atop the mound, the sparse hairs that ran along the lips, the nipple-like clit that stuck out and the pink folds at the drenched center.

And he could smell it, intense and heavy with exertion, the pussy he dreamed about was musky and thick like humid air. Nothing in the world smelled like it and nothing engorged him so much.

His cock was painfully hard. So hard that it woke him up before he could plunge it into that dream cunt.

He knew instantly where he was and who else was there. Cousin Linda's guest room, alone, except Isabel was just on the other side of the door.

The driving need was to slip his rock hard dick into Isabel's snatch. Rub it in and out and ultimately bottom out and explode deep into her womb. He needed to plant that seed and then again and again. Mark imagined her slender, tight body naked beneath him. Her toned arms pushed back against him, her slim fingers clutching him and urging him forward. His hand roamed over her muscled ass, squeezing hard and pulling her onto his dick as he thrust and thrust.

"Ohhh fuuuuucccckkk..." he groaned.

His balls ached so bad he was afraid to touch them.

Mark stood up and his vision tunneled as if he was about to pass out. He swayed on his feet and then stumbled towards the door. He stopped and wondered what he planned to do.

The ache in his balls was out of control. He reached down and pulled his boxers away from his erection. It was noticeably bigger than usual, the skin almost glowed pink in the darkness.

Mark found it hard to think and that realization made him laugh. He was a living cliche. He turned around and leaned against the door. He started jerking off his cock and wondered if that release would free him from this urgent need, remembering all that Isabel had said about her ordeal.

Isabel...

Normally any release, even just from his hand, worked perfectly fine, but this was different. A beating pressure in his mind kept mapping the path from this bedroom to the master bedroom where his sister lay sleeping. Images of her spread pussy, her taut, toned legs splayed out, her adorable little breasts with the pink nipples jutting out like eraser buds, her gorgeous face with those innocent eyes contorted by lust. "Holy shit," he muttered.

He had to try to take care of this himself, so he stumbled back to the bed and spit into his hand before gripping his shaft and stroking. Mark's mind conjured everything he could possibly need. He shamelessly entered into a virtual reality where he could see, taste and feel Isabel's body impaling itself on his, grinding her pelvis onto his cock. He stroked at a normal speed, tightening his grip towards the tip and easing up as he came back down.

It was working, he could already feel the release building up. His eyes fixated on his cock and stroking hand.

Just as he was about to approach the point of no return, the progress towards his orgasm stopped. How the fuck is this possible? He stroked faster, gripped a little tighter, and shut his eyes, forcing his mind to conjure the sensory impressions of fucking Isabel from behind. He mashed her down into the bed and fucked down hard, his trim stomach slapping into her ass.

It kept him amped, but nothing pushed him over the edge. His balls tightened and compressed as if held in a vice. "Fuuuucckkk," he groaned in minor agony.

He kept stroking, but the images of Isabel fled to be replaced by this deep awareness of her actual proximity. What would happen to him if he did not release this ache in his balls? The pain was getting worse. It transitioned from lustful need into sharp pain. Still his erection would not abate.

Mark rolled to his side and carefully got to his feet. Completely naked, he staggered to the door. His vision started to turn black. In the living room he walked hunched over against the pain, heading towards the master bedroom. "Isabel?" he croaked.

Then she popped up from the couch where she'd fallen asleep, her lithe body in only a t-shirt and panties. The sight of her smooth legs and hips, her pert breasts pressing at the too-tight shirt and her disheveled hair framing her wide-eyed look of shock - it all clamped down on his balls and he hissed in pain before he started to pass out. "Shit," he croaked before tipping over the side of the couch.

Isabel was shocked awake to find Mark falling towards her onto the couch. She tried to catch him, but he weighed too much, and all she managed was to roll him onto the floor. She was dragged to fall atop him.

His cock like a flagpole stabbed into her belly before getting pinned between them. It was on fire, far bigger than she remembered, and had managed to spear under her t-shirt and nestle up tight against the skin of her stomach.

Mark's eyes rolled back in his head and he made a semi-conscious groan.

Carefully she pushed herself up and could see his cock was bright red and clearly the source of his pain.

Shit shit shit,

she thought.

Why did you have to eat that fucking strawberry?!

Isabel sat back, resting her panty clad butt on Mark's upper thighs. Her hand reflexively grasped his member gently. Even without the influence of whatever aphrodisiac Aunt Maddie put in those berries, lust fluttered in her belly where Mark's velvety cock had just been throbbing. Her pussy was wet and she was light headed.

She stroked him and felt his engorged cock respond to her touch. The tone of his groaning shifted from pained to... something else.

Tears were in her eyes. Mark was fucking unconscious! She could feel panic welling within her chest, her breathing getting high and shallow.

But her hand kept doing its work.

That's it,

some part of her brain thought,

work that cock nice and tight. Up and down.

"Mark?" she said out loud, squatting with her pussy soaking through her panties and onto his legs. "I'm just going to stroke it okay? Like last night. I... I think I have to or... or I don't know what."

The size of his blood engorged member dwarfed her slender little hand. She started to go faster and could feel the friction build - he groaned - but now in discomfort.

"Lube," she said. "Got to lube you up baby." She reached into her panties and tried to scoop some of her moisture onto her fingers. It was a little better, but she needed more.

She stood up and scooted down, getting on her knees so she could suck him into her mouth. He was so big now she had to open her jaw up wide and could get less than half of that monster dick in her mouth, but it was enough to make the shaft slick.

He let out a gasp of pleasure and his eyes started to flutter open.

Isabel stroked and twisted both hands up and down his shaft, following the movements with her stretched lips. There was an intoxicating slurping sound as she sucked up and down.

"Issy?" He said dreamily.

She slurped up and took her mouth off him. "It's okay baby, does it feel better? Is it working?"

Then back down she went, like she was giving him CPR. She kept a steady rhythm, working her hands up and down even as she twisted them. She sucked hardest at the head, some instinct telling her that was the right approach.

"It hurts, keep going Issy, that's it..." Mark trailed off into incoherent moaning. Even as what she was doing turned her on, she was scared that Mark needed release now. She had to make him cum and fast.

She came up and said, "Yeah Mark, you like it when your little sister sucks your cock baby?"

"Oh god... Issy!" He grabbed the top of her head with both hands and started thrusting up at her. She felt his cock force its way in deeper and she gagged.

"I'm sorry!" he said and made to pull out.

Isabel shook her head and forced his cock back in her mouth. She sucked him hard and fought her way down that massive shaft. She whimpered as more wetness flooded her cunt. She groaned her pleasure along his dick. The texture and thickness and taste of his cock was intoxicating.

"You have to cum Mark, okay?"

"Yes I need to cum."

"Cum inside my mouth. Cum for your little sister."

"Oh god I can feel it. Issy it's going to..."

"Mmmmm-hmmmm. Schlrrrp. Yes that's it let it go baby."

"Oh god. Oh Issy. Oh please. Oh-ahhhhhh!" He grabbed her head and shoved himself further in. Isabel had to hold him back by pressing her hands down on his pelvis.

A hose-like torrent of jism streamed into the back of her throat. She gagged and choked.

Holy SHIT!

The next spurt was less forceful, but had triple the volume. She tried to swallow, but it was too much.

"Hungh!" he grunted and another spurt splattered onto her face as she pulled off him.

She went back to stroking, milking him for everything he had. "Get it all out Mark. Okay? Yes, do it!"

Two more little spurts of cum came out and ran over her fingers.
