This is a fantasy that very easily could have been a reality. Everything leading up to the protagonist leaving the guest room and going to his sister's room actually happened to me. I hope you enjoy: Adult Brother and Sister Finally Give In Part One of Two We were adults now, my sister and I. She was married and had 2 kids while I was still single and having fun. I lived ½ a continent away but came home for Christmas. My sister insisted I stay with her, the kids, and her asshole husband. I, of course, agreed. I got in a few days before Christmas late in the evening. We said our “hellos” and visited for a bit before I crashed out from the long drive. My sister and the kids went to bed soon after while her husband left for work since he was working the overnight shift. The next morning the kids were both off to school and my sister had left for work. Her husband had taken a nap and made some excuses about taking off which left me home alone–at least for a while. My mom was expecting me that afternoon so I had a little time to kill. There was quite a pile of clothes at the bottom of the stairs and, remembering my sister showing off her assets in g-string and thong panties when we were teens, I decided to see what kinds of panties she wore now. I found out quickly that her taste in panties had not changed a bit. If anything, her panties had gotten even smaller! I picked up a little black g-string and, seeing some of her grool on the crotch, brought it to my nose to inhale her essence. Her scent was all that I remembered and more. She had a younger, slightly fresher, muskiness to her scent that was so familiar to me from all the years of sniffing, licking, and sucking mom's panties while jacking off. Over the next couple of days that pile didn’t move. I jacked load after load down the toilet while sucking on my sister’s dirty gussets. I wrapped her dirty pantyhose around my cock, put her thong in my mouth, and sniffed the toe section of the pantyhose while shooting cum all over the shower wall. With my horniness for incest sex with my sister in high gear, I snooped through her bedroom uncovering more dirty little panties, stockings, nighties and the coup de grace, a plastic banana that she was obviously using as a fuck toy. After giving that banana a good licking to taste her pussy juices better than out of a cotton gusset, I didn’t think I could sink to any lower levels of depravity. I was wrong. I’d been out with friends having a few drinks the night before Christmas Eve. Although I tried, I didn’t hook up with any women at the bar so I went back to my sister’s house where I assumed everyone would be asleep. I came in through the garage, quietly so as not to wake anyone, and made a pit stop at the increasingly larger pile of laundry at the foot of the stairs. There were fresh dirty panties that looked like perfect masturbation material so I grabbed 2 pairs and headed up the stairs to the guest room. I noticed a light on as I climbed the stairs and assumed it was the bedside lamp in my room. That light was on but so was a lamp in the master bedroom. As I walked to my bedroom door, I looked to my right into the master where my sister was laying in bed with her knees drawn up making a tent out of the sheet. Neither of us said a word, we just looked at each other. I pushed open my partially closed bedroom door and walked in, closing the door behind me. I took off my shoes, socks, shirt and pants leaving only my boxer briefs on. I picked up the first pair of dirty panties that I snagged and inhaled on the crusty gusset like I was taking a bong hit. My cock was quickly becoming hard as steel as I brought the other pair to my nose and inhaled her musty sex smell again. Then, and what compelled me forward I will never know, I got up with those dirty panties in my hand, opened the door and walked to my sister’s bedroom door. She was laying in her bed with her knees down now and her legs crossed at her ankles under the covers. She was wearing a nightgown but nothing sexy and I certainly couldn’t see her tits or even her nipples poking through it. Still, without speaking, we looked at each other as I brought her dirty panties into view. Her eyes widened when she saw her dirty thongs in my hand and they widened even more when she watched me start running the dirty gussets under my nose and deeply inhaling the stale scent of her sex. My cock was at full mast and straining against my boxer briefs so I pulled the briefs down far enough to let my cock spring out. She still had not spoken a word but she drew her breath in sharply as she stared at my, her brother’s, hard cock while I continued to sniff her dirty panties. I reached down with my right hand and slowly started stroking my cock as I maintained eye contact with her. She continued watching me wide-eyed and that was when her right hand slipped under the sheet and she started touching herself. I walked into her and her husband’s bedroom and up to the side of the bed, continuing to stroke myself as my sister watched and masturbated herself. I dropped her dirty panties on the bed and pulled her nightstand drawer open and, taking my eyes off her only long enough to get her plastic banana dildo out and drop that on the bed next to her. She broke the silence and moaned, “You want me to use that?” I answered only by nodding my head. She said, “There’s KY in the drawer. Put some on the banana because I can’t put it in dry.” I simply smiled and began licking her dildo, tasting her juices on it, and slathering it up with brother spit so she could fuck herself with it. When I had it thoroughly wet with my spit, I handed it to her and, both of us in a state of near disbelief at what was happening, she slipped the dildo under the covers and closed her eyes as she slid it into her pussy. I could just make out the back of her hand as she fucked herself under the covers. She had drawn her feet up a little and had her knees splayed out as she continued to fuck herself watching me jerk off to her and her dirty panties. I glanced over my left shoulder into the master bathroom where I saw a white thong on the floor that she must have worn that day. I took my boxer briefs completely off and walked into the bathroom to get her freshest scented panties. Armed with these still almost warm panties, I returned to my sister’s bedside and, after having her watch me sniff deeply on these panties, I pulled the sheet back and broke my silence. “I want to see you fuck yourself while we jerk off together.” She slid her dildo all the way into her pussy then she piled the pillows up in the center of her bed and turned toward me allowing me the first full view of her wet pussy since we were teens and really the first fully naked view of her pussy ever as sexually mature adults. With her feet flat on the mattress about 8 inches from her ass cheeks and her knees spread, my view of her sweet pussy was perfect. She had golden pubic hair, not blond and not brunette, but a perfect golden sheen, and she had her lips completely shaven. The little tuft of pubic hair she kept over the top of her slit was almost like a sign that she was a woman and no longer a little girl. Since she had been masturbating with her dildo now for several minutes, her labia had opened up exposing her inner lips and her pink vaginal opening. She slipped a finger into her mouth and reached down and started rubbing the hardened nub that was her clit. She laid her head back and came hard for the first time then as me, her brother, watched her pussy flood her hand with her juices. Struggling not cum myself, I quickly took my hand off my cock and leaned down to smell her sex. She took her right foot and gently pushed me back at my chest and murmured, “Please don’t touch me.” I replied, looking intently into her eyes, “Take your nightie off. I need to see your tits.” Without responding, she lifted her ass up slightly and pulled the nightgown over her head finally letting me see her little tits with big, pink nipples that were slightly sagging from breastfeeding her kids. “Why would you want to look at these? They’re small and are saggy from the kids. I have ugly little tits. Just ask my husband.” She whimpered. “No. They are perfect. They are a small woman’s breast with perfectly suckable nipples.” I grunted fighting the urge to cum all over her body.
