Preface
A reader sent me his story and asked me to rewrite and flesh it out. I tried to keep much of his style, but it wasn’t easy, so it’s not in my usual style.
He said it’s his true life story, and I stuck to his details. So this is a true story, although not mine.
Life sucked.
I grew up in a single mother household. Well, my mother was bipolar and drove my dad away. He fought for custody of us, but the asshole feminist judge gave Mom full custody with a ridiculous amount of child support and alimony.
My dad did his best for a while, and after yet another major fight with Mom when he was trying to pick us up for a weekend at his house, where she was trying to get more money from him for one of her drug binges, he disappeared. I couldn’t really blame him as he was arrested a couple of times and spent some time in jail after he tried to take us by force.
In this fucked-up situation, Jenny, my older sister, got used to taking care of me; basically, she was the one raising me. She was a good, responsible sister. She made sure I got to school on time, I had enough food, etc.
Jenny is four years older than me, so when she was in college, I was in high school.
During our childhood, one of our Mom’s many boyfriends molested my sister, and I think largely because of that, she has an aversion to men and is very much a lesbian. She wasn’t butch. On the contrary, she’s very feminine. And all of her girlfriends tended to be tomboys.
I lost my protector and best friend when she came out to Mom. Mom blew a gasket then and kicked her out in the most cruel way, throwing her stuff out of the window and even pissing on some of them. I helped Jenny by stopping Mom when she squatted over Jenny’s clothes intending to defecate on them.
To say the least, Mom was batshit crazy that day, probably due to some drug she was taking that made her even more unhinged than her usual self.
I didn’t see Jenny for months after. I got wind that she was with some friends she had made in community college, living in an apartment across town.
One day, a cop cruiser came to my school and took me to my sister’s place. They told me that Mom had assaulted a neighbour she was trying to rob to get some drugs and would be in prison for a while. With no warning and no prior preparation, I was thrown into an apartment with my older sister and two women, one of whom was Jenny’s girlfriend.
Jenny was not thrilled with this arrangement to say the very least. I don’t even have a room in their apartment. I was assigned to sleep on a futon in a corner of the living room. No privacy for me, living with a bunch of women that didn’t seem to like men to begin with.
At that age, I had lost my virginity after being molested by one of my mom’s female friends. While I liked the idea of sex, having women simply barge into my room out of their minds on drugs and insisting that I pleasure them, even when they were disgusting due to very bad hygiene and my mother holding me down and forcing me to lick dirty hairy pussies, wasn’t exactly what I would call a good time. I was molested and abused just like men would abuse women and the way Mom’s male friends molested and raped Jenny. Even one of her boyfriends tried to fuck my ass, but I managed to escape.
So I spent the first day or so on my laptop at my sister’s. I didn’t leave the futon except to use the bathroom. I had hoped that the situation at Jenny’s would be better than home, but she barely talked to me. I was feeling miserable in a strange place where everybody seemed to hate me and my presence.
Bit by bit, I came to know my sister’s roommates.
Becky was a brunette with very large, natural breasts, nice hips and ass, but just like every hot-blooded male, her tits really drew me in. She was nice to me and also very flirty, often walking around in short-shorts and a T-shirt without a bra.
The other roommate, Jacky, who was my sister’s girlfriend, was a very stereotypical butch feminist, with blue and purple dyed hair, thick glasses, and just a nerdy boy demeanor.
Then there’s Jenny, my sister, dirty blonde, almost brown hair, perky breasts, and a round, bubbly ass.
During my first few days there, I saw my fair share of them making out and getting handsy with each other.
The first Friday night, they were all home. They started their evening by drinking wine and liquor in the kitchen and sharing a pizza. After the pizza was done, and I only got one slice, the roommates went upstairs, and Jenny came up to me, told me to stay downstairs and go to sleep, and under no circumstances to come upstairs. She turned the TV volume up and left.
I turned it back down and listened. For a while, all I could hear was giggling and laughing. Then I heard someone let out an unmistakable moan.
Since Jenny was treating me like shit anyway, thinking that I had nothing to lose really, I decided to investigate their activities.
Upstairs were two bedrooms across from each other. I found the girls in the room over the living room. The door was closed, but not completely latched, and I could hear them talking loud and laughing, while someone kept panting and moaning. Holding the door knob, I pushed the door in slightly, very silently.
What I saw is my sister on her hands and knees, naked. Jenny was suckling Becky’s breasts while her girlfriend Jacky was bent over her ass, seemingly fucking her with something.
Becky has the biggest fucking breasts, and my sister is playing with them like I long wished I could, stopping only to moan every so often.
As I watched surreptitiously, I realized that my cock had become diamond-hard that it practically hurt. To relieve the pressure, I slid my gym shorts down and started to masturbate.
The girls switched positions with Jacky lying on the floor between them, Becky sitting on her face, and my sister started eating out Jacky.
No more talking stopped, no words were needed anymore. All talk was replaced by short, bated breaths and moaning.
I was jerking off hard but also upset on some weird base level, very jealous seeing my sister with two girls, while she’s been treating me like crap. It was actually upsetting me so much I couldn’t continue masturbate.
Frustrated, I pulled my pants up and went back downstairs to the futon and went back to playing on my laptop.
About an hour later, I heard one of them coming down the stairs. I quickly closed the laptop and pretended to be asleep.
The kitchen emitted enough light that from my futon I could tell that it was Becky. She stopped and looked at me for a bit, but then continued into the kitchen and got liquor.
Carrying a bottle of something I couldn’t recognize, Becky came and knelt next to my futon.
“Are you pretending to be asleep?”
She was wearing nothing but panties. With no top on, her enormous breasts were on full display. They hung low, nipples pink and red, clearly affected by the activities that were going on upstairs.
I couldn’t play the silly game anymore, so I opened my eyes. I had no idea what to say, so I stayed silent.
“Were you listening to us? Could you hear all the way down here?”
“It’s kind of hard not to.”
Becky lets out a drunk giggle and asks me if I jerked off to them.
I simply nod.
“You know your sister’s up there, right?”
She breaks down into hearty laughs, but quietly, apparently she thought it was funny.
I leaned back a bit so that I could better see her quite impressive breasts that were on full display.
“Do you think I’m hot?” She asks with a strange hesitation as if she didn’t know that I would answer with the affirmative.
“Yeah, obviously.”
“Are you hard right now?”
I’m trying to figure out if she’s too drunk to be making sense. Of course I’m hard. I would have to be made of wet noodles to not be hard with her tits right in my face. But just nod.
At my nod, Becky put her right hand on my leg, grinning the whole time, moving up until she’s found the outline of my diamond cutter through my shorts.
She squeezed it playfully, sending an electric pleasure bolt through my entire body.
She takes her hand off my dick and grabs me by the wrist. “Come on.” And she pulls me off the futon.
She leads me up the stairs. She holds a finger over her mouth for me to stay silent. She goes inside the room, leaving me outside, but leaves the door cracked enough that I could see the activities clearly.
She pours the liquor down her cleavage. Jenny and Jacky take body shots off of her. It was soooo hot to watch.
More than once, she looks my way.
When my sister comes in for a shot, Becky pulls her up so that they’re facing each other on their knees and start making out while squeezing my sister’s ass, knowing full well I could see Jenny’s ass and back up a little to make her lean over more, spreading her cheeks and showing me my sister’s pussy.
Jenny takes Becky’s underwear off, straddles her thigh/knee, and grinds on her like a child.
Jacky was lying back with a dildo in her hand, fucking her own pussy slowly.
Becky pulled a small dildo from somewhere around her. I’ve never seen anything like it before. That red dildo was shaped like a spoon almost. She pulls my sister down to have her suck her big nipples, and she reaches over and spreads my sister’s ass, and starts fucking her with that weird dildo.
She keeps making eye contact with me, and every time she does, she fucks Jenny faster and harder.
I stood there in the hallway naked, obscured by darkness. I was jacking off furiously like I’m in heaven.
My sister gets so into it she ends up down on all fours, with Becky behind her, fucking her hole from behind with a bigger dildo.
Jenny was facing me directly, but I’m in the dark, I was thinking that she couldn’t see me. Besides, she was too busy moaning and thrashing about to notice me jerking off to her.
Jacky eventually gets up and in front of my sister and blocks my view.
However, soon after, Becky gets up and moves toward the door. I freaked out, and I jumped up and back against the wall, still naked, still hard, and my dick about to burst. She came out and closed the door most of the way. She looked at me and could evidently tell I’ve been jerking off. She stood right up against me, her breasts right in my face.
“You were jacking off to your sister. Isn’t that weird?”
I wanted to say not really, but all that came out of my mouth is the weak justification “She’s hot.”
“You sure are a creep!” She whispered, but she was giggling so much I couldn’t take it as a serious offense.
Becky had me pinned against the wall and ran the tips of her fingers lightly over my dick. Suddenly she flicks the tip ever so slightly and I almost cum on the spot.
Gathering my courage, I reached out and touched her breasts. She didn’t resist, so I started cupping both giant tits and kneading them. Her eyes went wide but she didn’t stop me.
About a minute later, the door opens behind us and I hear my sister’s voice sounding very drunk, and she slurs: “What the fuck are you doing?” talking to Becky at first, but when she saw me naked against the wall, her eyes got huge and she immediately reared a hand back and slapped me as hard as she could. Luckily, she was drunk enough that it didn’t land too hard.
I worried that Becky was going to leave me hanging, but she put herself between me and Jenny and defended me by saying: “Whoa Jen, hold on. I told him he could watch, I thought it would be hilarious.”
But Jenny was fucking pissed, “He’s a creep and I don’t want him around us.”
“Stop it Jen, it’s not weird or creepy to get turned on by three attractive girls parading half naked and making out in front of him. What’s up with you? You’ve been treating him like shit since he got here. What’s your problem?”
“It’s not normal for anybody to jerk off watching his own sister have sex!”
“Well you told us you two were really close when you were little, maybe he never got over it.” Becky replies.
It was hard to think with all that blood gathered away from my brain and in my cock. Especially with two beautiful naked women so close. But I had enough wits to realize that anything I contributed to the conversation between them would only make it worse.
Becky remained between us during this, and at some point she had backed up enough for her ass to be pressed hard between her generous cheeks. I was in heaven and hell. Heaven as Becky’s ass-cheeks felt marvelous around my hard cock, and hell because I didn’t dare hump as that would make a tense situation worse as it may distract Becky.
As Becky continued to defend me, she pulled Jenny to her and started rubbing my sister’s waist and sides, telling her having an audience isn’t going to hurt anything.
This went back and forth for a while, and Jacky got involved, but my sister finally just relented under pressure once Jacky said she didn’t care, and just told me to “Keep my fucking distance.”
I followed them into the room and Becky moved all of them to her bed, where they immediately got back to work kissing and fondling each other, lying on top of one another.
It was almost as if they had planned it, Becky and Jacky quickly had my sister on her back and had her legs spread wide.
I stood there staring right at my sister’s pussy, standing a few feet away, as they were giving me a direct view at her beautiful pussy, with Becky turning back to look at me every few seconds.
But then my view changed as Jenny closed her legs and was kissing Jacky. Soon enough Jacky moved and sat on my sister’s face, then spread my sister’s legs apart and started kissing from her knee down to her pussy, basically doing 69. It was fucking exhilarating watching her, then she pulled back and looked me dead in the eyes signalling my turn.
Following the clear hint, I crept closer like a fucking bandit in the night, not trusting Jacky not to be planning something nasty between me and my sister and snitching. I knelt on the bed in front of Jenny’s crotch, one hand on my cock, and I started planting kisses on my sister’s inner thighs, then ran my tongue along her pussy lips.
The feeling of her slippery lips and her amazing taste sent me over the edge immediately. I was helpless as I shot cum against the bed and carpet, but successfully resisted the urge to moan and crumble. I just retreated from the bed and just lay on the floor, watching them go at it, my whole body weak.
Becky replaced me and had her face buried between my sister’s legs, with her ass pointing towards me, giving me an unobstructed view of her butthole and pussy. I had gotten over cuming few minutes earlier and I got this stupid idea that worked out only of sheer grace of Becky being a generous goddess.
I crept up behind Becky and started rubbing my cock against her ass, reaching my hands around her and squeezing those massive melons, kissing all down her back like I’m a monk worshiping her holy fucking temple.
Becky turned back and I was relieved to see that she was smiling. She reached back and pet my hair like a child, wrapping an arm around my head and pulling my face into those beautiful breasts of hers.
I was in fucking heaven.
