During my mid-twenties I was living with my girlfriend Beatrice of four years along with her mother Linda in a two-bedroom townhouse apartment. Linda had been widowed for quite some time and was very close with Bea and very open about her relationships. She was also very open to the idea of all of us living together. Having lost my mother at a young age I was very close to Linda myself, often staying up late chatting about things and working on craft projects and such. One Christmas Morning we had all woken up early to first attend mass before doing our gift exchange. Upon returning home still dressed in our Sunday's best, we settled in to open presents. Linda kicks off her heels and kneels on the floor, wearing a thin knitted sweater and skirt set. She dawned petite but curvy frame, with shoulder length reddish brown hear and was wearing a rather long chain with large crucifix that hung close to her belt line. I admit I had never really noticed her before, but today she looked very nice, and smelled great. As we opened presents I found myself continually looking at her and noticing how much Bea looked like her mother. I began imagining what Linda may have looked like ten years ago, and how she would look in another ten years, and I was impressed. She really was an attractive woman. How have I overlooked this? Nearing the end of our gift exchange I was having thoughts I had never had before, in-fact I'm gonna classify them as fantasies about my mother-in-law. Imagine that! Here I am Christmas morning and it dawns on me that my in-law is a babe, and I now have the secret inkling to fuck her brains loose. Anyway, Linda says she’s gonna brew some coffee, so from her kneeled position, she leans forward, then swings back to gain momentum to get up on her feet. As she does, her crucifix on this long chain swings back and catches the bottom rim of her skirt as she continues to extend her body upright, in turn pulling her skirt up above her waist exposing her bare panty-less lower half. It took her a few seconds to realize that she was snagged but I don't think she realized she was exposed, or cared maybe? She stood there a few seconds and tried to unhook the snagged crucifix from her knitted skirt worried about ruining the material. Bea got up to assist her and as they stood there fiddling with the fabric, Linda's pussy was right there exposed to me. I just kept starring at her nicely trimmed mound and the hint of her tight pussy lips at the crotch. She then turned to walk towards the window for more light, as she did her ass swung gently two and fro, firm as could be for a 49 year old. Once at the window she turned my way again and her pussy was facing me once more, this time with piercing rays of Christmas morning sun shinning through, silhouetting that pussy to me. I swore a harked the angels singing. After about 2 minutes, the snag was loose and she proceeds to pull her skirt down, both of them definitely knew she had been exposed at this point but made no mention or reference about it. The in-law looked at me, had a chuckle and said, “Well now, I think I'll finally get to that coffee.” I excused myself to the bathroom hiding my enraged hard-on. Once there I tried to sort through the confusing thoughts and feelings of what had just happened. I mean one second I'm having a secret innocent fantasy about my mother-in-law who I just realized to be a hell of a babe. The next minute, by a freak divine intervention of a wardrobe failure, I learn that she’s not wearing underwear, and her pussy is a mere few feet from my face and she seemed in different about it. I felt like beating off about it right there but my girlfriend was calling out asking if I wanted cream in my coffee. Thinking to my self “yea, OK, I'm the one with the cream for your coffee” but, I quickly said, “yes please!” I composed myself and joined them in the kitchen. They were having idle chatter as I walked in, just then Linda says “Well sorry for my embarrassing Christmas show Alan ...” I snapped back with “For a second I thought I was looking at Bea standing there with how trim and tidy you looked ...” cursing myself inside, Linda continues “Why thank you, Alan, I do always pride myself in keeping groomed and I've always urged Bea to do the same ...” Bea chimed in with “Well I prefer to just shave it all off, its much easier that way.” I elaborated, “Nevertheless, I was impressed, and no one could guess that you have a 24 year old daughter Linda”. “You are so sweet for saying so Alan, I do believe I'm blushing now.” Then Bea continues, “Oh Mom has a tight body! I hope I stay on her tracks, I mean her breasts look better than mine I think, don't they Mom?” At this point I am choking on my coffee, I mean here we are talking about my mother in laws tight body and both Linda and my girlfriend Bea seem totally comfortable with it. “Go ahead mom, show him!” As Bea lifts up her Christmas sweater and then her lace under wire bra to expose her perky b-cup sized breasts with erect nipples and light areolas. “Go ahead, lets compare” she says. “Oh Bea, I think Alan has had enough don't you think?” looking a little embarrassed. Bea presses her again, to where she finally says “Oh alright Alan, here, what do you think?” She lifts up her thin knit sweater, as her full C-cup breasts get released to a gentle sway, hanging ever so lusciously, with silver dollar areolas, erect nipples, the slightest hint of a wrinkle in the cleavage, and a light sprinkling of freckles all over. “Oh boy, what a Christmas ...” I mutter, to which they both burst out in laughter. “See I told you!” said Bea, as Linda walks over puts her hand on my cheek and leans in to kiss my other cheek while catching the corner of my mouth as well. “Thank you, Alan. It's not everyday that an old lady like me gets compliments from a young buck like you.” “OK Bea, put your goods away and get to delivering these gifts to your uncles and meet me later for dinner” she says. As Bea and I drove in the car, Bea leans over and says, “Alan, mom has been very lonely and you made her day, you really composed yourself with the whole accidental exposure thing and made her feel good with your comments. Thank you, I know it means the world to her and it means a lot to me too”. At this point Bea had been rubbing my cock and was well on her way to working my pants open to give me a head job as we drove to her uncle’s house. “Feels like you need a little release ...” she says. Like I said, “Oh boy, what a Christmas ...” Summer time rolls around and not much else was said regarding that Christmas incident. The camaraderie between us three had improved and you wouldn't think that to be possible. I mean Linda wasn't so shy about covering up her bikini around the pool, and Bea had no problem playing grab ass with me in front of Linda. I now often fantasized about Linda, and it was fun. Everyday I would look at her and try to determine whether she had a bra and underwear. At times, I think she would catch me staring. We were well into a remodeling project in the townhouse in which we where converting a back sun porch into and enclosed den. Being a handy guy with tools, I was spearheading the project with Bea and Linda's help. After one Saturday night of hard work we all turn into bed, and I'm having trouble sleeping that night. I mean, I'm trying to build new construction to tie into existing, so my mind just keeps going over the angles of the crown molding work, and baseboards and such. Not wanting to wake Bea with my tossing and turning I get up at about 3 A.M, and walk to the semi-finished den and lay on a love seat that was just about the only thing in the room. Laying there with no light, my eyes adjust to darkness and I start to stare at the crown molding thinking “should I cut it this way, or take down the long side?” Etc, etc. Just then, I notice through the double door opening of the den, down the hall and off to the right, Linda's bedroom light comes on. The door is open so the light spills into the hallway and partly into the adjoining kitchen. “Mmmm, Linda's up, maybe she can't sleep either, if she comes out here, I'll ask for her opinion about the crown molding.” About a minute goes by and I can see a shadow in the light, out comes Linda from her bedroom and stops at the kitchen counter to pick up a magazine. As she stands there, I get ready to call out to her, carefully as I don't want to startle her, after all, it is after 3 A.M. and she won't be expecting anybody to be in the empty den. Just then, as my eyes continue to adjust to the light, I realize, that’s not a tan colored nightgown Linda's wearing...”Is she naked?” Unaware, and still reading the magazine, Linda lowers it a bit and I see the profile shape of her beautiful full breast. She then turns towards me slightly to rest an elbow on the counter, still looking down and reading I now see both her full symmetrical breasts, and just below the magazine is the contrasting racing stripe patch of neatly trimmed pubic hair. This site sent a surge down to my dick and out my toes. I mean I literally sprang to full arousal as the head of my cock just catches the edge of the opening of my boxer short underwear and just barely stays in. I was literally trapped in this voyeuristic situation where I could not move, or make a sound, or I would compromise my position, probably scare the shit out of Linda, and not to mention embarrass the both of us. I decide to lay still and meanwhile enjoy the view. After a few minutes, she puts the magazine down, enters into a body stretch raising her hands high into the air, arching her back, and standing on her toes. The view was magnificent, this now 50 year old looked as great as her daughter Bea, and I was willing to bet my whole tool cache that she was just as good a lover. Her full breast were out as far as can be, her ass high up in the air, her calves nice and tight from standing on her toes, and that sweet little pussy, was mocking me I tell you. Just then Linda makes a b-line toward the den. Still unaware that I'm in there I think, “Oh shit, what do I do?!” so, like any possum, I play dead, well I pretend to be asleep anyway. Linda flicks on the light and immediately gasps at being startled to see me lying there. Her gasp is immediately followed by a chuckle as she says “My word, what is this boy doing in here? He barely fits on that love seat.” She slowly walks up to me as I lay there face up with my forearm up to my brow, my legs sprawled and my eyes partway shut. I can see the fuzzy silhouette of Linda's beautiful body coming closer, then the eminent heat of her frame as she stands over me wearing nothing but a comforting smile. My heart is racing, I'm stuck there, when all the while all I want to do is jump up, pin her down and fuck her pussy raw. All of a sudden I hear and feel a slight popping sound as if something snapped loose, Linda gasps again and I realize my cock has broken free of the restraining boxer short fabric and springs out like a jack-in-the-box. I let out a fake snore, and continue my charade. Linda sits down next to me at the edge of the love seat, gently places her hand on my chest right over my heart, then ever so slowly, lowers the soft skin of her forearm close to her elbow onto the head of my pulsating cock. “Alan dear? You must be so uncomfortable.” Shocked and confused, I'm frozen in this stupid fake sleep phase, and as I'm figuring what to do next, she slides her hand down. Gliding her soft arm over the head of my cock, I feel the heel of her hand, then her palm, then her soft fingers wrapping around my cock head as she gently rubs the droplet of pre-cum that has jutted out. It occurs to me, that she's letting me off-the-hook. She's naked, waking me up, and grabbing my cock, I have no reason to pretend to be asleep anymore. I snort a bit and slowly lift my arm off my head, looking side to side and doing the blinky eye thing as if I had just woken. “Linda? Jeez, what time is it?” Still holding onto my cock, and shyly rubbing on it Linda says, “Where you looking at me all this time?” I was flushed, I was busted for sure, what will she think of me and what is she gonna tell Bea? “I ... I ... I'm sorry Linda, I had no idea you would wake up, and then I realized you were naked, I didn't want to startle you ...” Linda interrupts my rant with a comforting chuckle, then brings her other hand around to the base of my shaft, breaking her I eye contact with me she peers down at my rigid, pulsating cock. The head was bright purple and felt like it was gonna burst open, just then she looks back over at me and simultaneously lowers her mouth onto my rod. Slow and steady she strokes my cock stretching her lips around it and flicking the bottom part of my shaft with her tongue. With two fingers tightly wrapped around the base pushing the skin up and down in unison with her mouth, her other hand gently cupped and massaged my ball sack. I was receiving a masterful blowjob reminiscent of those I get from Bea. I am in total ecstasy at this point, letting this happen and enjoying every second. I enjoy the site of Linda's body sitting closely at my side, slightly twisted and hunched over as she bobbed on my dick. Every curve of her body, and fold of her skin was mesmerizing me. I place my hand just inside her knee, as to help her not slide off the edge; with this she opens her legs just a bit. As Linda continues working me I slide my hand up her thigh, feeling her smooth soft skin. Not really able to see from my angle I continue sliding my hand until I feel the immense heat emanating from her pussy. Once my fingers reach her lips, they were so wet and engorged that my fingers easily penetrate through her slightly compressed pussy right to the opening and without stopping I let my finger slide in. Linda pauses for a moment to let out a gasp breath and a desperate moan. She releases two or three blasts of warm air onto my penis as she recoups and continues to stroke her mouth over my cock as I am now vigorously fingering her. Not being able to hold it any longer, I begin to pant heavily, and advise her that I'm cumming, then Linda slightly lifts disengaging her mouth and lets my jets spray her gorgeous breasts. All the while I continue fingering her and at this point I have slipped in a second finger. I stroke more vigorously as her breathing intensifies, by now she has climbed over top of me, allowing me to stroke her as she moans uncontrollably with her eyes closed tight. “Don't stop, don't stop, don't stop ...” she says and just then she gasps and falls almost lifeless on top of me. I quickly catch her by her sides and hold her still right on top of me as she stabilizes her breathing. I can feel her juices that have oozed out onto me and drenching my shaft and boxer shorts. About 1 minute passes and she lifts her head and gazes at me. Her look is one of peaceful gratitude. “Thank you Alan.” she says gently. “It's been a mighty long time for me ... Too long ...” All I could do is just lay there and stare at her. “You look frightened Alan, are you OK? “I'm worried about Bea, what if she finds out?” I ask. Again Linda gives me a comforting smile, “I'll let Bea know that you took very good care of me.” “You're gonna tell Bea what happened?” I ask urgently. “Of coarse, silly, we are always upfront with each other, besides I've had this conversation with her before and she has always given me her blessing should anything like this happen between you and I.” Holly shit! I have had the green light from Bea all this time and just now is when this situation manifests itself. I felt like such an asshole. But then again, you know how it is, when you try to push a situation, it never works. Its best to just let it happen. As Linda lay face down on top of me, her pelvis over my lower belly, her head rested on my shoulder, I am totally relaxed but the exciting comments from Linda has sent blood surging new life into my dick. Linda continues, “I never came on to you Alan because quite honestly, I didn't think you noticed me. Do you find me attractive, Alan?” She whispers into my ear, “Wouldn't you like to fuck me?” Just then, my already surging penis springs forward to a full rock hard stage and slaps her ass making an echoey “thwack” sound in the empty and silent room. She smiles, “I'll take that as a YES!” she says as she starts to slide her body down. My dick digs deep into her crack and with the aid of all her wetness, easily punctures through and slides deep inside of her pussy. She gasps once more, lifting herself off my chest, closing her eyes tightly and hanging her mouth open as if in awe. She continues stroking, slowly increasing her cadence, as her full breast are swinging in a circular motion with her nipples fully erect. I am of average size at about 6” and that seemed more than she could handle, as she barely seemed like she was breathing, her face now wincing as if she wear in pain, but yet she kept vigorously stroking and devouring my dick with her pelvis. After about 30 more seconds she falls backwards bending my penis back exposing how it penetrates her engorged, well manicured pussy which is now pulsating and squeezing my shaft. Just then the intense heat of her juices engulf me and ooze out drenching my boxers once again and dripping all the way down my balls. Almost immediately I feel my rod pulsating uncontrollably, and at the enjoyment of having cum over her tits earlier, I pull out my dick and held it steady as I blast jet after jet of cum reaching up and over her head, onto her chin and trailing all the way down her chest, belly, and pubic area. She chuckles as she feels the load dripping making her tits jiggle then leans back up to view the fountainous display. “Wow, I do believe you would have launched me had you stayed in.” we both laugh and embrace each other as we tidy up and adjourn to our respective bedrooms. Having slept in the next morning, I am awoken by a perky and energetic Bea bouncing on our bed. “A talked with mom ...” she says. “Are you OK about it?” I ask. “Are you kidding me? My mother is an independent soul who just needs a bit of companionship every now and again, and you obviously fit her bill” “I mean she keeps going on about what a lucky girl I am, so thank you Alan. Thank you so much for perking her spirits up, and YES I'm OK with it, there's plenty of you to go around.” “So come on! Breakfast is ready!” And so, that’s how I came about my “Lover-In-Law”.
