Invisible Adventures of Jenny Pt. 01

Quick background and info (Feel free to skip this):

This is my first time writing and figured id post it for you all to enjoy, planning a few chapters for this so i hope you like it!

Jenny is a 21 year old college student that lives with her Mom, Dad and 18 year old Brother. She spends most her time studying and going to the gym, leaving her with a nice toned body along with a perfectly rounded ass and nice perky C cup breasts. Although she is very attractive she tends to stick to herself and doesn't have much of a social circle outside of a few friends that she grew up with.

Part One: The accident.

Jenny peered into the mirror with a look of confusion on her face, touching and grabbing at her naked body.

"Why do i have no reflection, am i a vampire or... dead, surely not! I don't feel dead, not like id know what that felt like anyways" she said softly glancing back and forth between her body and mirror.

She picked up a hairbrush from the desk next to the mirror and watched as the reflection disappeared infront of her and in shock dropped it and stumbled back in disbelief. Before it hit the wooden floor the brush reappeared on the ground, her eyes wide now as the loud clatter probably could have been heard from the hallway. The door handle shook and she jumped covering her perfectly round tits and shaved pussy as she let out a quiet shriek.

"Jenny you in here" her brother announced as the door flung open looking directly at her, almost as if he was looking right through here. Jenny stood there frozen, hands still grasping her naked body.

"surely this is a nightmare... can he really not see me" she thought to herself as she watched him step out of her room and close the door with a slightly confused look on his face.

Mark was a bit of prankster always poking fun at Jenny around the house, while he was only 18 he was much taller and bigger than her so she couldn't really do much about it most of the time. Instead she resorted to teasing by wearing tight fitted tops around the house and as she hated bras that often resulted in her nipples poking through being somewhat visible, she thought it was hilarious watching him try not to get caught staring and readjusting himself constantly as she flaunted around.

As the door closed she slowly followed and waited a few moments by the door gathering her composure.

"This doesn't feel like one of his pranks and if he had seen me surely i would of noticed the tent pole in his pants" she whispered to herself thinking about the time Mark bumped into her as she was coming out of the shower in her towel. "He practically blew his load and i wasn't even fully nude" she said while giggling quietly. Jenny opened the door slowly trying to make as little noise as possible pulling it open and slipping by as she watched Mark enter the bathroom with a towel now on his arm, her curiosity peaked more as she found herself walking to the bathroom door and pressing her ear against it.

"This feels so wrong but after all the pranks i don't care" she thought as she pushed the door open swiftly scaring Mark as he jumped slightly. Jenny stood there still naked as once again Mark just stared straight through her clearly now confused to what had just happened.

"Why isn't he as scared as i was" she thought as she watched him walking to the door in just his boxer shorts. The door closed practically in her face and lightly hitting her nipples causing her to slowly stumble back in surprise.

"I guess he really cant see me" she whispered while standing by the door thinking about what she could do next.

After a minute Jenny found herself moving back to the door and opening it again as she heard a "this fucking door is so annoying" from Mark, Jenny froze once more hand still on the handle of the door as she noticed he was now in the shower. She wasn't sure what she was going to do now her plan to scare him changed, she found herself stepping into the bathroom once again looking into the mirror... still no reflection.

"I could squirt him with some lotion or something surely that would work" she thought as she picked up the bottle watching it disappear in her hand.

"Maybe i just open the shower door i know that would terrify me" Jenny wondered while avoiding looking at the shower, she didn't really want to see her brother naked even though it was privacy glass so you couldn't really see much with that and the steam.

Jenny stood thinking about her next move as she heard alot of different wet noises coming from in the shower.

"Wow he's really thorough with showering" she naively thought. A few minutes must have passed now and she decided it was now or never as she turned herself to the shower keeping her eyes upwards nervously grabbing at the wet handle.

"This is gonna be hilarious, all those times he's pranked and scared me i can finally get my own back" she thought while grinning. Her hand now pulling, swinging the door open...

"Oh fuck, oh god... ohhh fuck" In surprise of the door opening, the pleasure quickly took over his eyes darted back and closed.

Jenny's face swiftly went from grinning and silently laughing to embarrassingly shocked as she glanced down slightly as Marks cock began to erupt.

"Please no, fuck... oh my god" she screamed in her mind trying so hard not to squeal or scream out loud.

Jenny being 5'2 and mark being 6'4 really wasn't ideal as the first rope shot from his cock spraying her tits and chin as she stumbled back as the second rope quickly landed on her tits and firmly toned stomach, she fell back to the floor sitting as the warm cum dripped slowly down her body. Her eyes widening in shock as she stared at his cock throwing rope after rope of cum across the floor.

"Holy fuck thats so much, why is it so much" she thought as she looked at her cum covered body and the pile of sticky white liquid amassing on the floor.

Jenny quickly scooted back towards the bathroom door lifting herself up and moving out of sight into the hall as she saw the last bit of cum dripping from the tip. She was panicking as she worked her way to her bedroom, she could feel the warmth from her brother's cum on her body.

"Ew, fuck. I can't believe i just watched him cum, fuck its all over me!" She said quietly.

Back in her room she stood infront of the mirror and noticed the cum floating on what would be her body, stood mesmerised as she watched it slowly work its way down her body dripping off her hard nipples. She quickly snapped out of it as she could feel herself getting more and more turned on by the second, Jenny grabbed a towel off her desk and started to wipe it off watching in the mirror as the towel disappeared.

"So I'm fully invisible and objects disappear when i hold them but liquid doesn't i guess" she whispered to herself as she finished getting the last of her brothers cum off her.

"Fuck i need to figure out how to become visible and make an excuse on where i was" Jenny thought.

Adjusting her clothes back on as she walked downstairs she thought about words and cues that could be how she turned visible again, as she reached the front door she stopped and started to think harder on becoming more visible tensing her body. Suddenly she noticed in the reflection of the glass on the front door her body and clothes started to reappear again. She tried again tensing and thinking hard on turning invisible and to her surprise it worked!

"Holy fuck, i actually can control this!" Jenny said smiling as she turned herself visible again.

She quickly opened and slammed the door announcing she was home as she usually does. She made her way to the kitchen as she heard Mark come down the stairs.

"Hey, where have you been sis" Mark asked his hair still damp from the shower.

"Oh i was just out for a walk, taking a break from studying and all" Jenny said trying to make lie sound legit as her face turned slightly red.

"Fair enough, good walk?" He said as he moved his way to the fridge grabbing a bottle of water.

Jenny stood for a moment "he probably needed that after shooting that huge load" she thought while watching him open the water.

"Yeah it was good really warm out today tho, i might go get a shower quickly before mom and dad get back" she replied.

"Oh well be careful the doors need fixing they kept opening on their own, i think it may have been the wind tho" Mark said glancing over her body.

"Okay well ill try jamming it shut, last thing i need is anyone wondering in id die of embarrassment" she said laughing as her face grew a shade of pink.

"I know right that would honestly be so bad!" Mark replied as he thought about her naked wet body.

"Anyways im gonna head upstairs and play some games" Mark followed up with.

After a few minutes she followed upstairs and entered the bathroom stripping off her clothes as she walked to the shower. "Atleast he cleaned up" she thought giggling. She turned the dial on the shower while stood just outside of its range as usually it spits cold before going hot. "Wait now's probably a good time to test this power out" she said leaving the shower on and quickly turning herself invisible as she made her way to the door. She opened it and slipped out closing it behind her to give the illusion it was still occupied when she saw light coming from Marks room.

"May as well go see what he's up to!" She thought as she drew closer to his room, his door was partly open enough to fit her slender body through.

As Jenny glanced through the door all she could see was his computer screen and the back of his desk chair. She grew curious and shuffled through the gap in the door now stood about 6ft away she noticed a picture on the screen a slim body with nice tits barely fitting into a bikini top and then it hit her... it was her.

"No fucking way, he better not be looking at my pictures. I swear to fucking god! How did he even get this picture" she screamed internally realising their mom must have posted a picture of all of them on vacation, but Mark expertly cropped everyone else out.

Her now curiosity turning into rage and realising she cant even say anything as explaining invisibility to her parents would be more difficult than explaining her brother looking at her picture.

As she got closer Jenny noticed a lot of movement in the chair she instantly knew what he was doing over her pictures, knowing she had to put a stop to it she got on her knees and sneakily crawled around the chair and under the desk towards the plug socket.

"Please dont cum, please dont cum" she kept repeating in her head as the groaning got louder and the wet sounds from the lotion could be heard more.

"Oh Jenny, i wanna cum on your perfect tits" Mark moaned as he sped up.

Hearing her name she instinctively looked his way and saw Marks hand sliding up and down his throbbing cock.

"Woah he's really going at it now" she thought while quickly trying to find the right switch before she gets painted with cum again.

His moans now growing louder she knew he was close. She flicked a switch and the room got darker "FUCK i was about to cum" echoed through the room as she giggled to herself. Mark was now leaning over his desk pushing buttons and his throbbing cock now bashing into the underneath of the desk just inches away from Jenny's face.

"Ew it's leaking on me again!!" She thought as the precum dripped down her body as his cock bounced around.

Jenny could feel herself getting wet this big cock practically in her face

"It's so big, gotta be 7-8 inches and its so thick. I've never seen one this size, to be fair ive only seen one other in person so" she said to herself.

Mark suddenly reached his hand down wrapping it back around giving it a few more tugs causing more pre cum to leak.

"I need to cum so bad, I'm so close. Come on!!" He said while furiously pushing buttons on his monitor and slapping the side of it.

"Oh no i fucked up, I really fucked up" she thought as she realised that his next move would be to check underneath the desk.

"He's gonna know something is here if he reaches down" she quickly tried to shuffle out now noticing with him stood up she cant get past without touching him.

"Im so fucked" her mind now racing thinking of solutions.

"Oh god im gonna have to touch it, im gonna have to make him cum" she said wincing at the thought of it. "Atleast he wont be cumming to my picture... just on me... fuck thats so much worse!!" She said while furiously unhappy.

Her hand reached up extending her finger out just barely grazing the tip. "Im not giving him a handjob i really cant do that its so wrong i cant" she thought as her finger now frozen underneath the tip of her brothers throbbing cock.

"Fuck lets just get it over with" she said to herself while slowly dragging her finger across the underneath of the tip.

"Oh fuck, oh my god yes" mark moaned out loudly.

"Wow that actually felt good for him" she laughed to herself as she dragged her finger across the tip again.

"Oh yeah! Oh yes, oh fuck" her brother moaned as more and more precum leaked out dripping down Jenny's hand.

"How am i gonna dodge this load he's gonna spray me right in the face and be able to see me!" She thought as she tested different angles to move her head out the way. The desk is a decent size horizontally but not enough for her to not be in the blast zone or shuffle out undetected.

Marks hand slowed with his strokes clearly trying to edge himself.

"I really gotta fix this computer so i can cum to Jen" Mark said attempting one more time at pushing buttons and adjusting cables on the monitor.

"Oh thats not happening!" She said to herself as she dragged her finger along the tip again.

"Mmmm fuck!" Mark moaned again clearly close. His whole body tensed up trying while trying not to cum.

"I bet my tongue would make him cum instantly, yeah thats not happening i don't want my brothers cum down my throat" Jenny argued with herself while opening her mouth.

"I gotta lick and dodge this so fast so there is evidence of his cum underneath here" she thought logically that it could work if she was fast enough.

Her tongue reached out softly making contact with the tip of his cock, Jenny moved her wet tongue slowly and instantly felt it convulsing.

"Oh no oh fuck, wha-t is t-hat" her brother moaned as his knees buckled he thrusted forward hitting Jenny's lips. His climax uncontrollably started and ropes forcefully shot out.

"Mmmmhgfd" Jenny grumbled quietly as his cock was now entering her mouth as cum hit the back of her throat for what felt like hours but was merely seconds. Jenny had never had someone cum in her mouth before so it took her by surprise, she gagged silently and pulled off as the last few drops trickled out of Marks cock.

Mark fell back into his chair panting from his orgasm as Jenny shuffled out from under the desk with a mouth full of cum and sped towards the bathroom.

"If this is a nightmare i need to wake up right now i cant believe my brother just came in my mouth" she said turning visible as she spat out the rest of the cum from her mouth, gagging multiple times from what she just experienced.

"Surely he's gotta know right? I mean he must have felt my mouth and be wonderful why there was no cum to clean up!" She said panicking when a light knock on the door started.

"Hey are you in here?" Mark asked while stood at the bathroom door.

"Yeah just in the shower dont come in!" She shouted back.

"Oh okay no worries was just curious" Mark replied and walked back to his room.

Luckily Jenny had left the shower running so it seemed plausible. She quickly jumped in the shower soaked her body and hair and brushed her teeth, she quickly swilled mouthwash to get rid of the taste of her brother and grabbed her towel before heading out.

She edged over to her brothers door listening in attempt to find out if he knew.

"Whatever that was felt fucking amazing my legs still shaking, holy fuck" Mark said unknowing that his sister was listening from behind the door.

"Thank god, i don't think i could go on if he knew it was me" she whispered as she made her was back to her room.

Back in her room she closed the door and flopped on her bed still wrapped in her towel she let out a big sigh, exhausted from her escapades she passed out quickly.
