Busted With My s****r-In-Laws Panties SeXStoRY

I hate doing laundry in the summertime. During the rest of the year it's not that bad, but in the summertime, my s****r-in-law is home from school, and stays with us, resulting in a fifty percent increase in the amount of laundry that I have to do. It wouldn't be so bad if she contributed while she was here, but all she ever seems to do is go out drinking with her friends and sit around on her ass watching soaps all day. I had no idea how she was able to pay her tuition for university. So, as part of my laundry completing, I made my way into her room. As I picked the laundry up, I noticed a purple thong on top of the rest of her laundry. It was oddly placed - if I hadn't known any better, I would have thought that she had placed it there, as if she wanted me to find it. Of course, that would mean she knew about my panty fetish, which I'd done my best to keep secret from everyone I knew, so I dismissed the idea as nonsense. I picked up the thong and brought it up to my face. Immediately the mixed scents of her perfume and vaginal juices filled my nostrils - whatever she'd been up to the night before, it was clear that she'd gotten aroused if nothing more. The smell that resulted was intoxicating, and I wasn't surprised to feel my cock start to harden. I stopped to think for a moment. My wife was out of town for the weekend, and my s****r-in-law had told me she was spending the day at a friend's house. That meant that here I was, with a pair of panties in my hand and a hard cock, I felt that there was only one possible course of action. I dropped the laundry bag, and my trousers with it. I quickly put one leg through the panties, and then the other one behind it, pulling the silky purple fabric up over my cock, which gets even harder as it feels the fabric start to constrict it. I start rubbing the fabric back and forth against my trapped cock, which eventually couldn't take it anymore, and sprang out from behind the elastic of the panties, forcing them down over my balls. I grabbed my cock, and started to jerk it, thrusting my hand back and forth. I quickly get into a rhythm with it, and start to gently squeeze in and out along with the back and forth motions. Even with the panties down at my crotch, I can still smell her pussy juice on it, and as I take in her aroma I can feel my cock swell larger, which prompts me to squeeze down harder on the tip of my cock each time I reach it. I start to punish my cock with harder, rougher jerks; between her glorious scents, and the pressure the elastic of the panties on my balls, I start to feel pre-cum leaking out of the head of my cock. I took it and rub it over the length of my shaft and continue to jerk, spitting onto my hand to increase the lubrication. By this point it's so moist I can close my eyes and imagine that there's a mouth around it. My breathing starts to get a little harder, so I take my free hand and use it to lean against the wall; it's been awhile since I've cum, either alone or with a partner, so I know this is going to be a big one. Part of me wants to slow down, and enjoy the experience more, but I'm feeling greedy, and just want to finish myself off as quickly as possible. I jerk harder and faster, harder and even faster, As I feel myself starting to approach orgasm, I take the panties and pull them back over my cock, putting my hand down the waistband and jerking from inside them. A moment later my cock exploded, cum squirting out all over the fabric. There seems to be an endless supply of it coming out, and the fabric of the panties turns so dark that I don't know if I'll ever be able to get the stain out. Which, I guess, means that these panties are going to become mine permanently and I'll have to tell my s****r-in-law that they got lost in the wash. "That should just about do it," I heard from behind. I turn around to find my s****r-in-law standing behind me, video camera in hand. "I think we find ourselves in an interesting situation here," she said to me with a smile. As soon as I saw my s****r-in-law, Jillian, standing there, video camera in hand, my dick goes limp and I felt myself start to sweat. It would be one thing if she freaked out – after all, she did just come home to find me in her bedroom, wearing nothing but her panties, jerking off into them. The fact that she wasn't freaking out, but instead waltzed across the room to her bed as if nothing untoward had happened, was unsettling. She put the video camera in the top drawer of the table beside her bed. "I have to say, John," she said after a moment of uncomfortable silence, "I really didn't know you were into wearing girl's panties. Hey, do you think my s****r knows?" My eyes went wide, and I could feel my heart start to beat faster. "You wouldn't." I immediately started to think about how my wife would react – she's a very conservative, vanilla lover, so I can only imagine it would not be a good reaction in the slightest. "I wouldn't?" she said confrontationally. "Are you sure about that? Because I'm pretty sure I would." She smiled as she spoke, crossing her legs sultrily. "I mean, why wouldn't I?" I tripped over my tongue trying to spit out a reason before finally saying "It would break your s****r's heart!" "You really should have thought of that before you started jerking off into my panties, John," she said flatly. "I mean, god, the front door wasn't even locked; it's almost like you were trying to get caught." I could feel myself getting red. "This is going to cost me, isn't it?" I finally said, broaching the subject that we were both thinking of. "More that you could possibly realize," she replied, her smile widening. I hated her in that moment, and yet she looked so sexy, so in control. "Let me go get my wallet, it's downstairs," I told her. "Oh, don't be silly John, I don't want your money," she told me. "No, this is going to cost you in other ways." "What do you mean?" "Well, for a start, I want you to stop hassling me about paying rent and getting a job during the summer, because I'm sick of hearing that shit from you." "Done," I said. Given how ineffective my hassling had been, this seemed to be a small price to pay. "Your real repayment, though," she said, uncrossing her legs, "is that, for the rest of the summer, you are going to become my plaything, unless you want my s****r, your wife, to see this little tape of mine." My eyes went wide again as I processed what she was telling me. Jillian was a hot little piece, but I had never cheated on my wife for as long as we'd been married – and cheating with her s****r would be the ultimate betrayal. But what choice did I have, unless I wanted her seeing the video? At the same time, though, wasn't I just putting myself into further jeopardy of being blackmailed if I agreed to this? I realized it had been a long time since I'd said anything. "Your plaything?" I stammered out, not knowing what else to say. "Like, sexually?" "Of course, sexually, silly" she said, the sultry smile suddenly getting exchanged for a more innocent-looking one. "There's a bunch of stuff I've been hearing about from girls at school, but haven't had a chance to try out myself. This should be a good chance for me." "Like, what do you have in mind?" I asked hesitantly. "Oh, all kinds of stuff," she said, lying down on the bed. As she did, I could see her skirt rise up, and almost got a glimpse of the panties she was wearing. "Nothing too intense just yet. But we have a problem, John – I was coming up here to have a nap, but I have to be honest with you, John. I got a little turned on watching you masturbate, and I absolutely cannot nap when I'm turned on. So you're going to have to do something about that." "What am I going to have to do?" I asked her, already getting visions of fucking her tight little pussy. "You're going to have to lick my pussy," she tells me, and I just about cum in the panties that are still around my crotch when I hear her say that. I didn't say anything in response, but just started walking towards the bed that she's laying on, and on which she'd already started hiking up her skirt. I learned as I walked that my attempts to look at her panties a moment ago were futile, because she wasn't wearing any, and also why she always takes so long in the shower in the morning – there isn't a single hair on her mound. I bury my head between her legs and start licking, starting with a few hesitant stabs at her pussy lips – she was already pretty wet by the time I got down there, so I get right into my routine, rather than taking it slow. "Yeah, that's it," she said as I started to go a bit faster, my tongue running up and down the length of her pussy. After a few of those, I go into a routine I'd learned in college, using my tongue to spell out the letters of her name against her pussy. She seemed to like that, so I went for her middle name afterwards, and then just started running through the letters in the alphabet. Eventually I stop doing that, instead starting to focus on her clit, rotating my tongue around it. She must of liked that, because she started running her fingers through my hair. Then I puckered my lips around clit, and started to blow, and she must have really liked that, because I felt her hand at the back of my head, pushing my face into her pussy. I took that as a cue to ramp things up a bit more, and start moving back and forth between her clit and the lips of her pussy, bringing my fingers up to join the fun. Eventually I've got three fingers stretched inside her, and my mouth back to hovering on her clit. She starts trashing around, calling out my name, and I can tell that I know a few things about pussy that the guys that she goes to school with haven't figured out yet. Then, finally, she let out one final moan, her hips bucking a good two inches into the air as she did. She laid still after that, trying to catch her breath, and I kept licking for a few more seconds to make sure that she was done. "That was amazing," she said to me, panting, as I finally lifted my head up. "What can I say, I hung out with some lesbians in college," I told her, "they gave me some good tips." She laughed at that, and I started to move the rest of my body between her legs, ready to pierce the pussy that I'd just been licking. My cock is rock hard again, sprung to action from the delicious taste of cunt juices. "Just what do you think you're doing?" she asked, putting her hand on my chest. "Oh, well, I just assumed..." "Oh no," she said, shaking her head. "I'm the one in charge here, John. I say what happens, and what doesn't. And for now, I'm fully satisfied, and really in need of a nap. So, I'll just talk to you later, okay?" "Uh, sure," I say, starting to move off the bed and towards the door. "I'll just "John," she says, calling after me. "You can hang on to those if you'd like," she said, pointing towards the purple panties that got me in this mess in the first place. Reluctantly I picked them up. It's going to be an interesting summer.
