When my younger sister, Sarah, moved in the early summer of 2020, I thought it would be a death knell to my sex life. She had just graduated college (barely) and begged our dad to essentially force me into letting her take the spare room i had in my apartment that my former roommate had vacated after marrying his longtime girlfriend. While the rent my parents paid on her behalf was nice to have, money was far from an issue for me and I felt i would have extreme difficulties explaining to my sister that i had a revolving cast of gorgeous girlfriends who were only available after nine at night, never ate dinner with me, and wore six inch heels. While I didn’t have trouble picking up girls, my deep seeded kinks were too extreme for casual hookups, and my workload was demanding and I didn’t have time for the demands of functioning relationships, friendships or sexual. The pandemic had made things worse as many of my friends had returned to their hometowns for the time being. Escorts had been my sole source of companionship and my preferred sexual outlet for months, and while I knew Sarah’s arrival might fill the companionship need, shifting from three girls a week who were sex pros to using my hand and VR videos sounded like a raw deal.
We had always been close friends growing up as siblings with a two year age difference, but we had grown a little more distant after during her pre-college summer she appeared to catch on to my use of her clothes and social media accounts that I used to feed a deep-seeded sister romance fetish I had developed thanks to a multi-year relationship with a cute girl named Lizzy who, in addition to being the split image face-wise of my beautiful sibling, insisted we role-play as brother-sister duo. Lizzy was a sex pro and a complete freak, and was likely the reason I no longer could get off from the vanilla sex that is expected with causal hookups. Because she lived in California in the summers, I resorted to voracious porn consumption from Incestflix and stealing my sisters used swimsuits, lingerie, and workout gear out of the bathroom to satisfy my unholy perversions. While sex with Lizzy had been subject a time limit of a few hours due to the physicality she desired, I could coast through hours of incest-themed porn (and curated galleries of my sister’s social media thirst traps) without any breaks. I was lucky and found a few porn stars that looked enough like Sarah that I could use what was then new “deepfake” technology to bring my perverted fantasy to life thanks to ample footage of her beautiful face I ripped from her fashion-oriented youtube channel. Most days I left my room only twice to eat and pee before going back to hours of uninterrupted immoral fantasies.
One of the few times I went out with old friends that summer, I came home late and beyond tipsy and started dialing Lizzy for some raunchy phone sex. Before I hit the call button, I made sure to lumber into me and my sister’s shared upstairs bathroom to borrow some props for the ensuing fun. I was in for a treat that night: my sister frequently made use of the new in-house dry sauna she had begged my dad for for years, but this time Sarah had neglected to take her sweaty and sexy one-piece swimsuit to the laundry room after showering. I left the bathroom trembling with excitement but was careful to remember to turn the lights off and the shut the bathroom door. About ten minutes into my call I thought I heard someone stop outside my door, but it was 2:00 AM and I was too far gone and horny to investigate. Deep into my brother-sister role-play with Lizzy (where I was pretending Lizzy was Sarah in everything but name and confessed to her all the things I was secretly doing with my real sister’s still sweat-damp bathing suit and latest fashion haul video), I could’ve sworn I heard some faint shuffling from outside the door. I told myself it was just echo from Lizzy, and went back to sucking on the intoxicating taste of my younger sister’s essence out of the crotch of her magenta-colored one piece. The taste of my sister’s sweat was familiar at this point, so I was surprised when I tasted the distinct flavor of pussy juice in the fabric. It seems my sister was enjoying the sauna more than my dad had imagined she would.
As I approached what was sure to be an epic climax, I was overcome with lust for my newly legal college-bound sister to the point of madness. I abruptly hung up on Lizzy so I could double down on my out of control deviance. I fashioned the bathing suit onto my Tempur-Pedic body pillow and grabbed one of Sarah’s small but seductive black satin bras I had managed to sneak into my permanent collection of treats that stayed under my mattress. I then preceded to nestle my face between the lightweight padded cups of the bra pretending they were her petite tits while thrusting my cock against the lower midsection of the swimsuit. I started moaning Sarah’s name and confessing to no one in particular how badly I needed to use her body. I quickly started shuddering and covered the sweet-tasting swimsuit in spurts and streaks of my thick white cum. I collapsed on top of the pillow as the streaks were joined by a large pool of my cum which had continued to seep out of my still pulsing cock.
I basked in the aftershocks of ecstasy while staring with awe at a screenshot of her beautiful face puckering for the customary farewell kiss that she granted her viewers at the end of her “fashion try-on hauls”. My breathing began to return to normal as the thick white cum transformed into dark stains on her suit. I slowly returned to consciousness but continued to hump the swimsuit and nestle into the bra while professing my love for her in a vain attempt to make the good feelings last longer. After a few minutes of this, I returned to licking the swimsuit’s cum-soaked lower half to help simulate the emotional and sexual experience that I imagined would come from eating my sister out after filling her with my seed. I had never desired to taste my own cum before, but the desire to experience what a real sexual relationship between Sarah, my beautiful sister, and me would be like made me savor every moment as my tongue pressed down on the fabric.
