The package arrived wrapped in pink cellophane covering a bottle of champagne, twin glass flutes, and a large box of chocolate covered strawberries. Isabel read the note proclaiming, "You two kids have fun!" in black magic marker. Deeply confused, she showed it to her brother Mark who said, "What the fuck?"

She placed the package on the counter that bordered the kitchen and dining room. The apartment belonged to their cousin Linda who was letting them use it so Isabel could visit a few colleges in the city while Linda and her husband were on vacation. Isabel watched her brother Mark's confusion deepen and knew she had to be making the same kind of face. This wasn't at all like Linda. "Maybe it's a joke?" Isabel said.

Mark shrugged and hefted his luggage into the far bedroom. "Pervert much?"

Isabel texted Linda:

Just got your package. Thanks?

Linda:

What package?

Isabel:

Choco Strawberries and Champagne. I'm not even 21 LOL.

Linda:

I did NOT send that. Is there a note?

Isabel sent a cringing emoji:

"You two kids have fun!"

She watched the three dots on her phone start and stop a few times. She called out to Mark, "Hey false alarm, she didn't send it I don't think!"

Mark came back into the living room. He was twenty three and had only just started working. The job market being what it was, he could barely afford rent an hour train ride outside the city - and that with two roommates. Their parents insisted he stay with Isabel in Linda's apartment - they were so over protective, not considering that she was 18 and would be fine to take care of herself even in the big bad city. Still, she secretly knew his presence made her feel safer and more at ease. She loved him and even though life had kept them at arm's length for the past several years, they still maintained a closeness that they both cherished - even if they couldn't articulate it out loud.

Linda sent:

OMG! I'll bet my mom sent that - I didn't tell her we were out of town. She's ALWAYS angling for grandkids. SORRY!

"Oh wow," Isabel said and showed Mark the text chain.

He laughed, but then looked a little flustered. He said, "Sex snacks" to try and break the tension, but it only made Isabel think of their cousin having sex.

Linda Texted:

Well they won't last a week - definitely eat the strawberries.

Isabel sent a strawberry emoji and typed:

Yum.

She didn't think about it again until later that night.

Isabel and Mark stayed up talking until almost midnight, which was nice, but he still had to go to work and she had her scheduled tour at NYU pretty early. It took Isabel a while to fall asleep and she assumed it was the strangeness of her cousin's bed or the sounds of the city that never seemed to abate. When she snapped awake and saw the glowing 3:12AM on the bedside clock, she knew something was wrong.

Her body felt warm. Not feverish, but heated and she kicked off the blankets to cool down. Her mind was having a hard time focusing as she lay there staring at the pattern of street lights on the ceiling. Unbidden, she recalled scenes from an old movie she'd watched that weekend with sexy dancing. The male lead's ass in tight pants.

She shoved that out of her mind and it was immediately replaced by thoughts of the boys at school running around in their gym shorts. Then Mister Callahan, her best friend's Dad. He had heavily muscled arms and he always showed them off in tight t-shirts.

WTF?

It was as if the thoughts were being forced into her mind, churning rapidly. She turned over and then again, trying to get comfortable. The heat was emanating from her sex. She'd been horny before, but it didn't happen very often and never with this intensity.

She got up and stalked out to the living room. In the dim light of the apartment she saw the open box of strawberries on the counter. She's had one while her and Mark were talking about life and his lack of a girlfriend. He'd given her a smirk and said, "Sex snacks." She'd scrunched up her face in disgust, but eaten the strawberry anyway. The chocolate was drizzled on and flecked with a kind of gold dust. The chocolate was a little too bitter, but the luscious red berry inside was juicy and the combination had tasted luxurious on her tongue.

In the kitchen now she poured a tall glass of water and drank half of it down. She thought the movement from the bedroom into the kitchen would break whatever weird dream-horniness was gripping her, but if anything it was getting worse.

She was wearing an old t-shirt and granny panties. Her fingers lifted up the shirt and slid under the panties to caress her slit. She was drenched. For a moment she'd almost thought she'd wet herself.

What is going on with me?

Her pussy swallowed her index finger and her middle finger soon followed. She groaned too loud and realized she was frigging herself in the middle of the apartment. With an effort of will she ran back to the bedroom and shut the door. In the bed once again she skimmed her pantied down and slid two fingers into her sopping cunt and pressed the palm of her other hand down on the top of her mound.

Her breathing huffed and her movements sped up. The image of her friend's dad and his heavily muscled arms was what stuck in her mind. Some small part of her hated it, but she felt desperate for any release. She made assumptions about the muscles of his naked ass (which she'd never seen) and how they would look pumping between her teenaged legs. Isabel imagined herself taking him in - with no frame of reference. She'd never been fucked. She'd never done anything more than kiss a boy, and less sexy and more awkward. All of it slid away in the frenzy of her fingers rhythmically thrusting in and out, her palm push and grinding, and the image of Mister Callahan ramming into her.

Her orgasm built up and twitched through her lower stomach and out along her legs, but the epicenter stayed at her cunt. It shattered her and she lost all sense of time and place. Isabel was gone for a moment of pure fulfillment.

But it was lie, the need did not stop.

She was panting hard and felt as if she was being dragged along by her animal need - she was NOT in control. "Oh shiiit," she said.

That's when Mark opened the door.

For Mark the benefit of the week living in cousin Linda's apartment was that his morning commute would be shorter and he would get to live away from his roommates. Seeing Isabel was fine, but he didn't relish babysitting her or dealing with their parents checking with him to make sure he was keeping an eye on her. He was an adult and living out of the house, but they still acted like he was a kid. Some small part of him knew he was being a bit immature, but he couldn't help how he felt.

Isabel was different, much more grown up than he remembered. She for sure looked way more grown up and his first thought seeing her in her pre-bedtime shorts and t-shirt short-circuited his male brain for a moment. He assessed her as a man. She was athletic with a tight body that was trim in the midsection, flaring out into a taut, but rounded butt and enough breasts to ensure no one would think her boyish. She had a brilliant smile and her caramel colored eyes seemed to drink you in. He snapped out of that mindset right quick and was glad the solution was not for her to crash at his apartment because his roommates would have certainly made plays for her.

They stayed up too late and talking about their lives showed him she was grown up as a person as well and that almost opened up a wonderful aspect for him - he started seeing her as someone he could have an adult relationship with - it would be nice as life evolved and they had each other.

Despite all of that, he still had to get up in the morning, so when he heard her moving around the apartment at three in the morning he was more than a little perturbed. He lived with two other guys so he was used to distractions and he almost got back to sleep. Almost.

Then he heard her exerting herself. It sounded weird.

He'd never lived with his girlfriends. The last two never got that serious and even in all the years at home with Isabel and their mom, he'd never heard anything like this.

Was she sick or something?

The bedrooms were separated by a closet, but he still heard this strange sound that had to be her and it sounded like... she was either having a really good or a really bad time. The second instance was louder and weirder.

Mark got up and moved out to the living room. He paused, listening again. Maybe he still heard something. Frustrated and tired - how long would it take him to get back to sleep - he moved closer to her door. He was about to go back to bed when he heard her say "Oh shiiiit..."

In two quick strides he was at the door. He didn't knock, just twisted the knob and stepped inside. There was not a lot of light coming from the living room's dimness and only bands of a street light showed through the blinds in cousin Linda's bedroom, but Mark caught a quick glimpse of Isabel splayed out on the bed naked below the waist.

She quickly snapped the covers of the bed over herself and hissed, "Hey what!"

Mark reached for the light and switched it on. He didn't think to be embarrassed. In truth his brain had not properly caught up to what he might have seen or what it could mean. He was firstly pissed to be awake and secondly worried something was wrong. She looked... wired. "I heard you shout," he said. "Is everything okay?"

She opened her mouth to speak and instead started twitching. He breath was coming in short pants. She was flushed and beneath the covers she was squirming. "I.. I don't... know."

He came closer; his worry driving out any irritation. "What's happening to you?"

She panted a couple of times, like someone trying to catch their breath. Her eyes fixed on him and seemed to rove over him. He slept in his boxers and nothing else, and suddenly realized he was standing almost naked in front of her. There was a desperate look in her eyes, but the way she focused on him, it came across as lust.

"You're not breathing normal," he said. He came closer and was now by the side of the bed. "Were you...?"

She pressed the cover to her face, "Omygodthisissoembarrassing."

"Uh.. look... it's... just... are you like okay?"

"No."

"What is it?"

"Oh god."

He sat down on the bed, "I mean everybody does..."

She rolled her eyes, "Yes I know everyone does it... this is different." She was still squirming under the sheets and her breathing was better, but still shallow.

"Different how?"

"I just... you know... took care of it and it's not stopping or going away."

"Oh."

"Has that ever happened to you?"

"I mean I've gone more than once..."

"No," she hissed. "Like right away it's somehow worse. The need to... god."

He slowly got up. "So maybe just do it again okay. I'm going to..."

Her hand lashed out and latched onto his arm. She was warm and something about the way it felt being in close proximity to her was intoxicating.

Oh my god,

he thought,

she's in heat. And it's affecting me.

"I'm scared," she said. Her eyes met his and locked him in. He would do anything for her in that moment - he knew this was one of those moments where all bets were off and she needed him.

"Okay, just tell me what's actually happening. Okay?"

She nodded vigorously, her eyes never leaving his and he made an effort to keep his eyes on her as well - as if that deep human connection could act as a healing conduit somehow. She said, "I woke up and it was overwhelming."

"The need to..."

"I was horny, but not like normal horny, like burn down the world I need to get fucked horny."

Mark swallowed and reminded himself he was in it now and just because they never talked like this normally, he could handle it. "Has this ever happened before?"

"No."

"When was the last time you had sex?"

"Never."

"Masturbated?"

"Like two days ago."

He nodded. "Maybe something happened earlier today?"

She suddenly squeezed his arm as if she might crush it and let out a groaning whimper.

"I'm taking you to the emergency room."

"Pleeeaase no." She groaned again. "I just need to do it again." Her eyes sought him out and bore into him, "I don't think I could maaake it anyway. Ooooooh."

She was definitely fingering herself under the covers. He watched as her arm pumped furiously.

He said, "And that's not helping?"

Her mouth opened and she came while staring right into his eyes. It was an expression he'd not seen on too many women. Once with his first girlfriend they has orgasmed at the same time while he was fucking her and it was an almost holy experience. But this, this was a bottomless experience. She was staring into him - with him and yet not with him. His cock was like steel in his boxers and his own breathing felt high and tight in his chest.

She said, "I've cum like three times and It. Won't. Stop."

"I'm calling 911," he tried to get up, but she held him in place.

"I think... I think I need something in me. Yes, oh god I need a fucking dick."

For a moment he had this bizarre memory of a time when he had to pee on a female friend of his who got stung in the foot by a jelly-fish.

I can't fuck my sister.

Then he thought,

Linda!

"Hang on," he said. "I have an idea."

She released him and he started searching through the bedside table drawers. Frantically he pushed through hand cream and tissues and the random bullshit everyone kept in their night stand. Then he ran around to the other side and that table was clearly Linda's husband Grant's space. It was more useless. "Underwear drawer!" he exclaimed.

"Mark?" She groaned. He could see her eyes hooded, looking at him in no way a sister should ever look at her brother. She was locked onto the tent in the front of his shorts.

He tore open the chest of drawers on the other side of the bedroom until he found the one with cousin Linda's panties. His fingers pulled them up and out of the way and... "Bingo!"

Mark turned around to present his sister with a 7 inch thick black dildo.

Isabel threw the bed cover wide open to expose her splayed legs and pussy. "Mark, please yes come fuck me with that!"

Her mind was not working right and she knew it, but Isabel was powerless to stop herself. The need to be fucked was akin to a runaway train and had built momentum - she had to have a cock inside of her and until Mark found that dildo she was on the verge of demanding he fuck her with his cock.

God - the thought of it was everything.

He came closer, but was moving too slowly, uncertain. She could see the look in his eyes - having her splayed out before him was having an effect. She could see his erection poking out the front of his boxers. It was wrong in every way for her to want this, but the need to be filled was beyond right and wrong - it was on a biological level like breathing. She would do anything for it, and some part of her mind knew to get what she needed, she would have to draw him in further.

"Listen to me," she said, her voice strained, but still coherent.

His eyes moved from her open and wet pussy to her eyes. He looked confused, scared, and turned on.

She said, "I know this is weird. I know, but listen. Listen." She swallowed against a wave of sensation. The power of the horniness was that it heightened all physical sensations around her lust. She could smell him - the hormones pumping through his body to prepare him to breed her. She could feel the pressure inside her pussy, the bed covers pressing against her smooth skin. Her nipples hardened and responded to the air in the room. "I'm sorry to have to ask you to do this, but I'm scared and and and... I know I need to release something. Okay? It's just a thing, it doesn't have to mean something more than than a..."

He said, "I get it. Just like an embarrassing procedure you can't do yourself. So I'm helping you do it. W-we can be mature about this."

She nodded, relieved to hear him say it and she could tell he was going to do it.

"We probably need lube," he said.

Isabel laughed, "No we do not."

"Oh. Right." He sat down and paused as if he didn't know how to proceed.

Isabel reached out and gently grabbed his wrist, the one holding the rubbery black dildo. It was floppier than she expected, but mostly stayed rigid. It had a suction cup on one end, but otherwise looked like a circumcised penis complete with veins, a mushroom style head and the indication of a hole at the tip.

The contact of her hand on his skin was electric. It made her shudder and gasp and she heard his intake of breath. She guided his hand down and the dildo towards her slit. She saw his eyes drop down and lock there. He seemed surprised. She said, "I'm very... wet."

He nodded mutely and the tip of the dildo pressed against her. She adjusted to better line it up and even moved her hips. Her bare leg brushed against his side and the contact was enough to make them both inhale.

"Oh god yes. Push it in Mark. Huhhh - uhhhhh." She lost coherence as the dildo penetrated her. Her eyes rolled back in her head and she yanked his wrist forward to impale herself.

Then he stopped and she looked at him with pleading eyes. There was a mixture of love and lust and caring and she felt connected to him. He nodded some understanding as he started to saw the dildo in and out of her pussy.

She let out a groan as another orgasm pulsed through her. "D-don't stop. Keep. That's. Yeah. It."

She listed to his breathing as her own body convulsed around the fake cock. The points of her thighs that connected with him - the body warmth and naked skin - exhilarated her and she released his wrist to put her hand on his naked chest. He had thin black hairs that contoured his pecks. She caressed and clutched and even lightly scratched. He could not decide if he should stare at her glistening pussy as the dildo slid in and out, or into her eyes. Isabel stared into his eyes, relishing the power she had over him.

Another, bigger orgasm was building and some part of her knew this was the final release she needed. Except it was building and never arriving. Something was missing. Something she needed to fulfill this biological need.

"Need..." she yammerted, her tongue thick in her mouth.

He kept sawing in and out of her and said, "What Issy, what do you need?" Hearing him use the pet name he called her when they were kids somehow made it all the more dirty and intimate. "Tell me," he asked in a husky tone. "Tell me what I can do?"

"Cock," she stammered.

He wasn't getting it, thinking she was talking about the dildo. She let her hand trail down his taut stomach to his crotch. She touched his cock through the thin material. He let out an involuntary breath, but did not stop what he was doing or pull away.

Isabel reached into her brother's shorts through the front opening of his boxers and grabbed his cock with her hand.

She'd never held a penis before. It was rock hard, but encased in soft velvet. She gasped at the contact. Something wet streamed from the tip and coated her hand. She stroked him seeing him react. With an animal urgency he skimmed off his boxers and got up to crouch beside her on the bed.

Isabel scooped up the wetness pouring out of her pussy and coat her hand. She reached back and took firm hold of Mark's cock and jerked her hand up and down its slick length.

"Tighter," he instructed her and she gripped it tighter.

The feel of his cock in her hand and the dildo Mark was sliding in and out of her pussy was doing the trick. His breathing increased and he started fucking her hand, thrusting his hips forward and she crunched her stomach muscles to lift her head. Without a word he knew what she wanted and scooted forward.
