Taboo Tastes with My Mother-in-Law

I’ve always wanted to write down a story, and two weeks ago, something wild happened that gave me one worth sharing. This is my first shot at it, so bear with me.

I’m Jake, 28, married, standing at 5’10” with a solid build — not a gym rat, but my years of rowing have left me with a strong back and shoulders. My hair’s dark blonde, my arms are decent, not ripped but not skinny, and my legs are sturdy from years of sports. I’ve got a firm backside, or so I’m told. Here’s what went down two weeks ago.

My wife, Chloe, is average height, with generous, heavy breasts and a thick, curvy lower half — her hips and ass are a showstopper, perfectly matched by her toned thighs. She’s eight months pregnant, so her mom, Margaret, came to stay with us to help out around the house, giving Chloe a break while I’m at work. Chloe still heads to her office job a few days a week. Margaret, 59, is short, maybe 5’2”, with an even fuller figure — her backside is rounder than Chloe’s, her breasts larger but softened by age, carrying a natural weight.

Margaret had been with us for four days. I work the graveyard shift, so I only catch her when I drag myself home at dawn or after I wake up in the late afternoon. On the fourth day, Chloe had already left for work when I got back, leaving just Margaret at the house. She was in the shower when I walked in. I trudged to our bedroom, tapped on the bathroom door, and called out.

• Morning, ma’am, I’m home, – I said, sticking with “ma’am” like I always have, even now that she’s my mother-in-law.
• Hey, good to know, hon! I’ll be out in a sec to whip up some breakfast, – she replied, her voice warm.
• No need, I’m probably just gonna crash, – I said, exhausted.
• No way, you’re eating first. Hang tight, – she shot back.

I slumped on the bed, waiting maybe five minutes. When she stepped out, she came over, planted a quick kiss on my forehead, and headed downstairs to cook — still wrapped in a short bathrobe that hugged her curves but covered everything. I followed, plopping down at the dining table. Then I heard a clatter — a fork hitting the floor.

• I’ll get it, ma’am, so you don’t have to bend over, – I offered, but the words caught in my throat. Margaret had already squatted to grab it, her robe riding up, baring her full, rounded backside. The sight was unreal, her curves even more pronounced in that position. She stood, the robe still hitched above her hips, and I couldn’t tear my eyes away.
• Got it, no worries, – she said, turning. She caught me staring, flushed red, and tugged the robe down. – Oh, Jake, I’m so sorry. That wasn’t supposed to happen. I’m mortified.
• It’s all good, ma’am, don’t sweat it. We’re family. It’s not like some random guy saw, – I said, trying to sound casual.

She plated up breakfast, and we talked about my night at work. I thanked her and headed upstairs to sleep, but that image — her bare, voluptuous form — was burned into my brain. It stirred something primal. Trying to unwind, I started touching myself, scrolling through some steamy online stories. Midway through, a twisted idea hit: what if Margaret walked in? I left the bedroom door half-open, stripped naked, and lay on the bed’s edge, fully exposed to the hallway. I stroked slowly, deliberately, waiting for her to come up.

When I heard her steps on the stairs, I let my eyes flutter shut, peeking just enough to see. Margaret stopped at the door, her gaze locked on me. She started to move toward her room but doubled back, standing still, watching. I expected her to do something bold — maybe touch herself or step inside, like in those fantasy videos — but she just stared, expression unreadable. I picked up the pace, letting the thrill carry me, and finished with a shudder, my release spilling across my chest. I opened my eyes as she slipped into her room, leaving the door ajar. Seizing the moment, I stood, still naked, and walked to the bathroom for tissues, acting shocked when I “saw” her.

• Ma’am, crap, I’m sorry! I thought you were still downstairs, – I said, covering my groin with my hands.

She looked rattled but said, – It’s fine, Jake, really. This is your house. You do you.

• Still, my bad, – I said, playing it up. – While I’m here, got any wet wipes? I, uh, made a mess. – I knew she had some in her room.
• Yeah, let me grab ‘em, – she said, starting to move.
• No, I’ll get them, – I cut in, dropping my hands to reveal my semi-erect length. I stepped to her nightstand, grabbed the wipes, and started cleaning myself right there, my pulse hammering. I was nervous as hell but too deep to back out.
• Can I ask you something, ma’am? – I said, voice low.

She didn’t look away, her eyes flicking over me. – Sure, hon, anything.

• Did you like what you saw back there? – I asked, point-blank.

She froze, cheeks flaming, struggling to respond.

• It’s okay, you can tell me. We’re tight. This stays between us, – I said, stepping closer.
• I… God, it’s been forever since I felt that kind of rush, – she admitted, voice shaky. – My husband hasn’t been able to… you know, in years. We gave up. But seeing you, my heart was pounding. My body lit up. I wanted to… to come closer, to touch you while you were there, eyes shut. But it’s wrong, Jake. You’re my son-in-law.
• Chill, no one’s gonna know, – I said, voice steady. – Let me make you feel alive again.

I rested my hand on her head, gently guiding her toward me. She hesitated, eyes wide.

• This is so messed up. If Chloe finds out, she’ll despise me. You’ll split up, – she said, almost pleading.
• She won’t. Just do what you wanted to do back there, – I urged, firm but soft.

She leaned forward, taking me into her mouth, her lips warm and tentative, no hands. Within moments, I was fully hard — about 7 inches, thick and heavy. She struggled at first, adjusting to my size.

• It’s too much, I can’t take it all, – she gasped, pulling back slightly, her breath ragged.
• Just keep going, ma’am, you’ve got this, – I said, my hand lightly pressing her head. – Don’t stop.
• Stop calling me ma’am, – she said, voice husky. – Call me Mama. It… it gets me going, hearing you say it while I’m doing this to my daughter’s man.
• Alright, Mama, keep sucking. I want all of you, – I said, my own voice catching.

I pulled her up from the chair and set her on her knees. She dove back in, reaching for me, but I guided her hands to my hips instead. She gripped me, pulling me deeper, gagging as I hit the back of her throat, her saliva coating me.

• Damn, Mama, you’re a pro. Bet you were a firecracker back in the day. Now you’re gonna be my firecracker, – I said, half-growling.

I helped her stand and told her to strip. She peeled off her robe, revealing heavy, sagging breasts with wide, dark areolas and a soft, curved body. I laid her on the bed, latching onto her nipples, sucking hard until she moaned, her hands clutching my hair. I moved lower, kissing her smooth, freshly shaved skin, her scent musky and intoxicating. My tongue explored her folds, teasing her clit, and she writhed, already soaked.

• Oh, God, don’t stop, – she begged, voice desperate. – My husband never did this. I’ve craved it forever. Keep going, please, deeper.

I worked her with my tongue, flicking and sucking until her thighs clamped around my head. She came hard, a gush of release soaking my chin — something Chloe’s too reserved to let loose.

• Put it in, now, Jake! – she demanded, her voice raw.
• Anything for Mama, – I said, sliding into her in missionary, slow at first, her warmth gripping me. I sucked her breasts, biting gently as I thrust deeper. Then I flipped her over. – Let’s do it like Chloe’s favorite—doggy.

She got on all fours, her full ass high. I kissed her curves, teasing her tight ring with my tongue until she squirmed, begging. I entered her again, gripping her hips, each thrust making her moan louder, her body shaking.

• Yes, Jake, I get why Chloe picked you, – she panted, five years my senior. – Show me everything you do to her… and what you haven’t.

Her words were like fuel.

• Alright, Mama, you’re mine now. I’m gonna do whatever I want, but first, you’re giving me something extra, – I said, lying back. – Sit that perfect ass you flashed at breakfast on my face. That’s what I’m craving.

She straddled my face, her weight settling over me. I devoured her, my tongue alternating between her slick folds and her puckered ring as she ground against me, her moans muffled by her thighs. After a while, I put her back on her knees, thrusting deep, my hands digging into her hips. I spat on her back entrance, easing my thumb in, pumping fast. She didn’t flinch — she arched back, moaning louder, urging me on. I pulled out, lined up, and slid into her ass, something I’d never done with Chloe. The tightness was unreal, her gasps turning to cries of pleasure. I thrust until I couldn’t hold back, finishing inside, my release spilling out as I pulled away. I caught it with my fingers, bringing them to her lips.

• Eat it all, Mama, – I said, voice low.

She did, her eyes locked on mine. I cleaned up with the wipes, showered, and collapsed into bed. It’s been over a week, and three more times when Chloe’s been at work, I’ve hooked up with Margaret, each encounter pushing the boundaries further.
