My Ex-SIL Mommied Me

It was common for my wife's brother and his wife to come over on weekends for a BBQ and a swim. However, about two years later, I got divorced, my wife moved out, and the weekend BBQs stopped. But, my SIL, my ex-wife's brother's wife, still liked to use the pool and sunbathe, this was something she did on the regular and nobody thought anything of it. She'd let herself in through the gate, enjoy the pool and the sun, and then go home. No big deal. 

After the divorce, I got a new job and started working from home and my home office had a window that looked over the pool. On the third day of working from home, I'm busy working on my laptop, and I see something out of the corner of my eye, and there's my SIL, or ex-SIL, laying on her stomach on a lounge chair wearing a very skimpy bikini. I could clearly see her tight little butt. She doesn't work, so she spends her days doing yoga, goes to the gym, and runs. She's very fit. And I caught myself staring. I see that she's starting to turn over, so I quickly look back at my screen. 

She eventually goes home, but she's back again the next day. This time, I see her walking across the yard to the pool wearing cut off jean shorts and tank top. I decided to go out and say hello. By the time I get out there, the jean shorts and tank top are piled on the cement and she's wearing the same tiny bikini that's straining against her large breasts and the bottoms were not much more than just strings and a small triangle. She was arranging her towel, with her back turned to me, slightly bent over and I couldn't stop staring at her ass. I make a coughing sound, and she turns around, a little startled, and tries to cover herself with her hands. When she sees that it's me, she lets her arms drop and I'm treated to the full view of her absolutely amazing body. 

"I didn't know you were home." She says. 

"Yeah, I started working from home this week." I replied.

"I hope it's OK, I can still use your pool." She says shyly. 

"Yes, of course it's OK, just because you're not officially my sister-in-law, you're still a good friend."

She blushes while she's picking up the sun tan oil and starts applying it to her shoulders and arms. I tell her she has free use of the pool anytime and tell her to enjoy the bright sun. I turn to go back inside, but she stops me and says, "Could you help me with some oil on my back?"

I gulp as I watch her lay down on the lounger, her arms crossed under her head, all I see is one tiny string across her back and another tiny string disappearing between her cheeks. ‘She's practically naked' I'm thinking and I fight myself from getting aroused. ‘Just think about the work project I'm supposed to be doing…'

I take the bottle of oil and start to rub it into her shoulders and down her back. She squirms a little and I could have sworn she spread her legs a bit. "Um, is that good?" I say, not wanting to start rubbing her ass without permission. 

"Well, you don't want my legs and backside getting burned, do you? Please be good and finish." She said this rather sternly, like a teacher telling a student to behave.

I gulp and take a good long look at her ass while I squeeze the oil. I start at the lower back and slowly run my hands over her incredibly firm backside, and down to her thighs. I don't linger, I work quickly as my dick is now fully erect in my gym shorts and if she turned her head, she'd see the effect she was having on me. I quickly finish her calves, put the bottle down, and say hurriedly, I have to get back to work. She tells me, see you tomorrow. 

I go back inside and sit down at my desk, my erection not going away. I squeeze myself as I look at her through the window. She's now on her back and applying oil to her stomach. I started to rub one out watching her, feeling guilty, but goddamn she was hot.

The next day, sure enough, she was back. We started the routine of me again applying the sun oil. But this time, being more confident, I took my time with her shoulders and back, almost like giving a massage. I take my time covering her ass, giving her firm squeezes, her responding with a slight squirm, her legs visibly separating. I ask if this is OK, as I rub her inner thighs, not quite touching her pussy through the thin fabric of her suit. The smell of oil and body heat rose through the air.

"That feels amazing," she says and I swear she raises her hips just a bit as I continue to massage her thighs, moving down to her calves. "You forgot my feet yesterday. Please be a good boy and don't forget today." And with that, she flips over. Her breasts bounce as she moves and my cock twitches. She must have seen it as I was again wearing thin gym shorts that really didn't hide much even when I am soft; but she didn't let on and didn't say anything. 

I'm now kneeling at the end of the lounge chair, a towel on the ground to help my knees, and I begin to rub oil on her feet. At this point now, it felt like I was giving her a full body massage, from her shoulders to her toes. I look up at her and she's looking down at me, smiling. Her nipples are hard through the bikini top and my dick starts to ache with tension. 

"I think I'm done." I say as I stand up, fully showing my erect cock through my shorts. She takes an obvious good long look but doesn't say anything. I awkwardly head back into the house to rub out another one. Afterward, I'm feeling guilty, this is my wife's, my ex-wife's brother's wife, they are still married. I shouldn't be doing this. But she's doing it as well. She must know what she's doing. I feel conflicted and torn. I tell myself, if she shows up tomorrow, I won't go out there. 

Sure enough, the next day, she's back. I watch as she shimmies out of the jean shorts, exposing her bare ass in the thong bikini, how she stretches to remove the tank top with her bouncing tits underneath. She does a few yoga poses and reaches for the oil. But I see her looking around, like she's waiting for me to come out. When she realizes I might not be coming out today, I see her head towards the house. I lay down in the bed, in the same gym shorts and t-shirt and I don't know what to expect. 

I hear a soft tap on the back door and the screen slides open. She calls my name. I tell her I'm in the bedroom. A quick moment later and she's in the doorway, leaning against the frame. Wearing only the string bikini, her strong fit body, her breasts straining against the small triangles of her top, the bottoms of her bikini proving that she keeps herself well trimmed down there. Her legs are toned and tan, her perfect little feet. All of that: standing in my bedroom doorway. 

"What's wrong? I was expecting you." She says, sounding a little cross.

"I'm sorry, I guess I'm not feeling well today." I stammered out.

"Oh! Poor baby," she says very maternally, "Can I do anything to make you feel better?" She starts to enter the room and sits on the edge of the bed. 

"I don't know. I'm just feeling guilty." My head is swimming and I'm not sure what I'm doing.

"Guilty about what? You poor boy. Mommy's here and she wants to make you feel better." She leans closer to me and softly runs her hand down my cheek. My body instantly responds. ‘Mommy? Did she call herself Mommy?' As she leans closer, her breasts are now inches from me. I can smell her. My mind whirls.

I look at her with big puppy dog eyes as she places her other hand on my chest, feeling my heart beat. 

"I guess I'm feeling sad about the divorce, about not having anyone in my life. I miss being with someone." I say kind of pathetically.

"Oh! You poor thing, we all need someone, don't we?" Her hands start to rub small circles on my stomach, she leans in even closer, her tits now an inch from my face. "Can Mommy help you out?"

I look up at her, feeling like a little boy who's faking being sick to stay out of school. "I don't know. How could you help me?"

With that, she sits up straight, undoes her bikini top, and lets her heavy breasts fall free, her nipples are hard and round, bright pink, her breasts a soft milky white, her body a golden tan. Blood starts flowing to my dick. Her hand is still making small circles on my stomach, moving up and down my chest. She leans in again and places her boobs right in my face. 

"You're such a good boy, you can suck on Mommy's tits. They are here for you. They will make you feel better." She places one breast directly in front of my lips, which parts open and my tongue naturally swirls around her nipple. She moans and places more of her breast in my mouth. I take as much as I can. I am now rock hard and straining against my shorts. Her hand never stopped moving. "Did that help?" She asks me as she sits back up. 

"Yes, but now I have such tension. It aches, it kind of hurts." She looks at me with mock confusion. 

"Tell Mommy where it hurts." She stares into my eyes, her bare tits exposed to me, I take her hand and place it on my erection over the shorts. She pulls back surprised, sits back and looks at the tent in my shorts. "Oh. That's normal. Mommy can help with that." She gives my dick a good squeeze through the shorts. She takes a hold of the waist band and I help her get me out of the shorts. My dick springs out and she gives a quick gasp. "My boy is certainly big, isn't he?" And she gives me a firm tug. 

"Yes, please help make the ache go away." I say to her, falling into my new role.

"Mommy's here for you." She slowly stroked my cock while placing her tits back in my face. I start sucking, licking, kissing, worshipping those large magnificent breasts. Her strokes increase in time and I start to moan. She strokes faster. I moan loader. Faster still and I'm sucking her tits like there's no tomorrow. "Give it to Mommy. Give it to me! Be a good boy and cum for Mommy!"

That's all it took. An explosion of cum rushes through me, it lands on the wall, the bed, on me. 

"Do you feel better now?" She asks, her face as flush as mine. 

"Yes, Mommy, I feel much better now," I say as my dick starts to soften. She beams back at me, apparently very happy that I called her Mommy. 

"Good. Because there's something I want you to do for me." She stands up and removes her bikini bottom. She's completely shaved and I see her pussy lips, puffy and inviting. "I hope you're good at this," she says as she straddles me, her knees on either side of my chest, she bends down to let me suck her tits a little more and then she starts inching up. Soon, she's kneeling over my face, her pussy inches from my mouth. "Eat me, good boy, show your Mommy how much you care." 

And with that, she lowers herself down on me. She's already wet and I can taste her, smell her, feel her heat on my lips. I dart my tongue in and out. I swirl my tongue in circles. She lets out a moan. I find her clit and wrap my lips around her, ticklinging with my tongue. She gasps, she squirms, she moves up ever so slightly and starts grinding her clit against my nose.

"That's a good boy!" she says as I grab and squeeze her ass as she rides my face. I feel her juices flowing, I'm swallowing as much as I can, but still, I can feel it coating my chin, my cheeks. My face is covered with her juice as she continues to grind. Her intensity mounting. My dick now rock hard again. She reaches back with her hand and grips my erection.

"You make Mommy very happy!" She says as she swings herself around. We're now in a 69, I feel the warmth of her mouth and the softness of her tongue as she sucks my cock while I go back to licking her soaked pussy. Up and down her lips, sucking her clit into my mouth and popping it out, her slurping up and down my shaft. I feel her change position again and she plunges herself down on my cock, riding me like a cowgirl. I grab her ass as she rocks back and forth. I watch my dick slide in and out of her soaking wet cunt and she's moaning and I'm moaning and I say I'm about to cum and she suddenly stops. 

"Not yet. Mommy didn't say you could cum again." She turns around, still over me, her hot wetness just above my twitching member, her proud breasts and hard nipples coming back towards my face. She plunges her soaking pussy back down on me and smothers me with her tits. She's fucking me again and I thrust my hips in synch with her, grapping her ass and guiding the motions, as I start kissing and sucking on her tits again. Those glorious, soft boobs that were so warm, so comforting, so enticing. Without warning, she arches her back and yells out, "Mommy's cumming! Mommy's cumming! Cum with me, do it, be a good boy! Cum inside Mommy!"

I shoot a hot rocket of cum deep inside her. She moans, she shouts, "Oh my fucking god!" and then collapses on me. Her tits back in my face. Her pussy still clenched around my cock. We both pulse in the afterglow. Our bodies are a sweaty mess, hearts racing. Slowly, we catch our breath. 

After that day, I always make sure Mommy is properly oiled for her sunbath and she always makes sure her good boy doesn't have any aches or pains.
