My Sister Flashed Me [MF] [incest]

The second story of my sister, Kate, and I.

Brief description of Kate: Slender newly 19 year old recent high school graduate. 5’4, 115 Lbs. Athletic, lithe build with a toned ass and body. 34C tits. Blonde hair, green eyes.

Me (Tom): 21 year old college student home for the summer. 5’9, 185 Lbs. Athletic build, 6.5 inch cock.

This story takes place about a month after we fucked the first time with her friends there as well.

I walked into Kate’s room at about 3 PM, bored and looking for something to do. It had been about a month since I had fucked her along with her friends, Mindy and Denise, and we hadn’t talked about it since, so I walked in with the idea of just messing with her and, since I had nothing better to do, annoy her to keep my boredom at bay. Kate was sitting on her bed, texting or something on her phone, while my younger sister, Brooke, laid on the floor doing the same. I walked up, sat down next to Brooke, and asked what they were doing. Neither sister was excited about my being there, as they both looked at me and sighed, not really responding. With nothing being said, I decided to up the ante a bit and moved over to Kate’s bed, jumping on it and putting on the full court pressure as I tried to get any sort of reaction out of her.

Brooke looked up at me, confused as to why I was bugging them so much, but Kate leaned herself up, giving me a glimpse of her black lace bra as she did, and tried to push me off of her bed. I laughed as she put forth a feeble effort to knock me over, and pushed her back down playfully, not needing much effort given her slight frame. Kate pushed back again, but showed more frustration this time and was able to move me a couple of inches, though not enough to knock me off of the bed. I pinned her down at that point and laughed again, letting her know I was in control if I wanted to be, but also glancing over at Brooke to see her reaction.

“You guys are weird,” Brooke said, “Tom, why don’t you just leave us alone?” I looked at my younger sister as she made this plea, but didn’t move off of Kate, holding her down and tickling her as I did. Kate writhed underneath me, but her expression remained less then pleased. Finally, I let go, though I remained on the bed, infringing upon her space.

Kate looked at me, exasperated at this point, “Tom, would you leave us the fuck alone! I have to change and if you don’t get out, you’re going to see things that you don’t want to see on your little sister…” She trailed off, as if forgetting that I had seen, and experienced, everything that she had to offer for the most part. Brooke looked up at me to see my reaction, and when I didn’t move, voiced that she was going to go over to a friend’s house since I was pestering them, and headed downstairs to get ready. I glanced back at Kate, waiting to see her reaction. She looked up at me, her expression unchanged, and reiterated that if I didn’t move, she was going to start getting undressed. I had to stifle a laugh, knowing that this was certainly no motivation for me to go anywhere, and watched as she lifted her shirt to expose her bra. I sat back for a minute, watching her and seeing just how far she would go, but was surprised to see her unhook her bra and let it fall away from her body, showing me her breasts for the second time in the past month.

Once Kate was topless, I wasted no time and leaned back towards her, taking one of her pert little nipples into my mouth. She grasped the back of my head and pulled me into her, pushing aside any doubt that this was exactly what she wanted and had used the guise of flashing me to get me to go away as a way to lead Brooke away and off of the scent of what was actually going to happen. I sucked and nibbled at her nipple, feeling her push up against me, and laid her back onto the bed as I continued to tease her. I let my growing hardness press into her as I continued my assault on her nipple, and Kate moaned as she felt the pressure against her body, her thin shorts and panties offering little protection for her pussy. I continued to grind into her as I alternated from left nipple to right, and then moved my lips to her neck and began placing tiny kisses along her jawline before moving to her ear as well. When I reached her ear, I felt her stiffen and take a sharp breath. I smiled, knowing I had found a particularly sensitive area, and licked along the inside of her ear as she moaned deeply and moved her hand between us, gripping my cock through my shorts. It was my turn to take a deep breath this time, as she countered my teasing assault with a few quick strokes of my cock before reaching into my shorts and wrapping her fingers around the base, stroking again inside of my shorts as I struggled to maintain control.

I moved to her lips and began kissing her forcefully, the pleasure of even just her hand on me driving me wild, but also used this opportunity to grab her ass with both my hands, massaging her cheeks and slowly inching her shorts down. Once I had her shorts low enough, I pulled away from Kate and flipped her over before she could react, giving myself a fantastic view of her teal thong-covered ass. I moved quickly and began placing kisses along her ass, pulling her thong away from her as I went, and as soon as I had her slit exposed I dove in, pressing my tongue into her and licking her, tasting her sweet juices. Last time I had done this, I was dividing my attention between Kate and two other girls, but today, I made sure that she knew exactly how much I enjoyed spreading her tight little lips and making her squirm in pleasure. I licked and sucked at her pussy, spreading her wide open at times, taking my time to make her as wet as I could. She moaned and wiggled underneath me, her face pressed firmly into one of her pillows to muffle her noise just in case Brooke hadn’t left yet. I replaced my tongue with my fingers and began thrusting them into Kate at a quick pace while I moved on to the next stage of my plan, to experience the one part of Kate that I hadn’t had the pleasure of doing yet.

With Kate distracted by my fingers inside of her, I moved my mouth to her puckered asshole and placed a kiss into it, letting my tongue just emerge from my lips and into her. Kate bucked hard against my mouth and fingers when she felt this, but showed no signs of fear or disapproval as she continued to moan, so I began to enthusiastically eat her previously untouched asshole as she moaned and whimpered at my efforts. I could feel myself getting harder and harder as I felt her enjoying my work, and continued licking and sucking her forbidden treasure while my fingers alternated between pressing into her and rubbing against her clit, increasing her wetness every second. Once it was clear that Kate had no objections to me playing with her ass, I withdrew my fingers and pulled away from Kate, positioning my cock along her pussy and pressing into her slit, causing her to scream. I pumped into her for a few quick strokes, using one hand to keep her in position with her ass in the air and face in the pillow, and my other to reach around and pull and tease a nipple. I withdrew my cock quickly from Kate, causing her to moan in frustration, but quickly lined it up against her moist asshole and began pressing into her slowly. Kate tensed up for a second before pushing back against me, helping my cock inch into her. Knowing that this was the first time she had had a cock in her ass, I made sure to go slow and give her a chance to adjust. As she got more comfortable and began pushing back onto my cock, I started to rock in and out, sawing my cock into her tight, previously unused ass as I gripped one of her breasts in my free hand. I started to find a rhythm, thrusting in and out of Kate’s ass as she tried to match each thrust with one of her own, and could feel an orgasm building within me. Knowing that I was getting close, I picked up the pace and moved my other hand back down to Kate’s pussy, massaging her clit as I felt her start to tense up as well. At this point, I started to pound Kate’s ass relentlessly and felt myself letting go, my cock throbbing inside of her and releasing the first stream of cum as I exploded. Kate writhed against the bed as her own orgasm took her, her ass tightening around my cock as she screamed into the pillow. It took me a second to feel or hear anything other than my cock releasing stream after stream of cum into Kate’s tight ass when I realized that wasn’t all that I could hear.

“Oh my fucking god!” I heard, and looking at the door to the room, I saw Brooke standing there, her mouth wide open in shock as I came down from my orgasm inside our sister. All I could do was look at Brooke as my cock softened inside of Kate before replying.

“I didn’t believe she would actually flash me…”
