I tried to form a response but was silenced as she prowled up the bed like a tigress. Her body slithered over mine until her pregnant belly bumped my face. I opened my mouth to speak but stopped when she straddled my head and I came face-to-crotch with her pussy. Its lips were engorged with desire and dripping wet. She'd not exaggerated the horny part. Her pussy looked desperate. The nest of dark curls above it was disarrayed from her unsuccessful rummage earlier. I could smell her pungent need like an animal musk. Immediately my dick began to stir back to life. As she lowered her pussy, my mouth opened, ready and eager to receive her. With no more preamble, she settled herself down on my chin, her meaty outer lips wrapped around mine, and my nose was buried in her coarse tangle of pubic hair. "I don't expect you to do better than my wife," She warned, "But if you don't make me cum with that tongue of yours you're going to regret it."
Her smell was rich, her taste tart but delicious. I gave her slit a tentative brush with the tip of my tongue. She showed her approval by settling more fully on my face. I had to use my nose to breathe through her sex-scented pubic hair. I could only see the underside of her curved belly, it eclipsed all else. When I let the flat slab of my tongue slither from her anus, over her entrance, and up to the top of her cleft she let out an appreciative groan. I felt my confidence grow. I could do this. I could make my sister come. I'd played through every possible ramification of this situation in countless dreams and fantasies.
Wetly, I began to munch on the thick leaves of her fleshy pussy. She oozed a slippery nectar which soon coated my tongue, ran down my face, and drenched my neck and chest. At first, I focused on her entrance. It was tight and elastic. I tongued apart the funnel of her labia and began to push my tongue deeper and deeper. Soon my tongue had snaked its way into her as far as I could stretch it. She took hold of two clumps of hair on either side of my head and began to ride my face, essentially fucking my tongue like the dick she so craved.
"Yeah, that's it," she purred, "Not bad, little brother. There might be hope for you yet. Right there. Ooh."
Her clenching cunt sucked at my tongue. I let her bounce on it until I felt her need for even more. Then my tongue slipped out of her hole and slapped her flaps around. While she rocked her hips back and forth I rested my elbows on the bed and, using my hands as a platform, lifted her ass up. My fingers sank deep into the firm flesh of her buttocks, which rippled beautifully with the motion of her body. This way I was able to position her just right to lick deep into her hungry pussy. I soon found her engorged clitoris. It was swollen to the size of a 9mm round. Poor thing, this at least went some way to explaining this morning's craziness. Almost immediately my lips and tongue began to work it like a speedball.
I licked and swallowed, licked and swallowed. Her juices flowed down my throat. I could tell Jane was getting close then, her grip on my head had tightened and she began to brutally hump my face, grinding her pelvis into me with such force I thought she might break my nose. She shoved me so deep into her crotch I couldn't breathe. I tried to warn her but my voice was lost in her cries of pleasure and muffled by her body crushing down on me. All I could do was lap at her in desperation and hope she reached her climax before I passed out.
As she approached her peak I gave up on any attempt at precision. All I could do was hold out my tongue and let her bounce her off it as she slapped her crotch into my face over and over.
Suddenly she shifted, gripping my hair so tight with one hand I feared she might pull it out by the roots. With the other she reached back and seized my freshly reforged cock. Trust me, there is no better elixir for a spent cock than the taste of your sister's pussy in the morning. She rode me bronco style like that, my dick acting as the saddle post. Being nearly suffocated by my sister's pussy was somewhat offset by the pleasure of her roughly jerking on my cock.
Then, grunting like a tennis player, she slammed into me so hard that my head cracked off the backboard. I was seeing stars as her pussy went supernova. She shrieked. Her pussy was so fused with my open mouth that I could feel the sheets of muscles behind it oscillate with violent contractions on my tongue. She shook and shuddered, her tight belly bouncing off my head like a basketball. Her hand crushed my poor cock and yet even that felt amazing. I continued to lovingly eat out her quivering slit even as her rigid muscles finally began to unlock. Eventually, her internal spasms dying away, she peeled her sopping mess of a pussy off my face and sat back on my chest. Her legs were splayed wide and I was looking straight into her spread lips, watching her entrance still gasping with the death throes of her climax. She was untroubled by my open stare or by the fact that I was heaving at the air like a drowning victim who had just been brought back by the kiss of life. She just offered a catty smirk while she continued to gently stroke my cock.
"Good boy," she panted, patting my head in the most patronizing manner she could manage. She glanced back at my inflamed member and grinned wickedly before saying, "Now we can really get started."
I gave a soft whimper.
Jane released my shaft and climbed off me, her hand moving in an unconscious and protective manner to cover her belly again. I bravely lifted my head up to peek at what she was doing. She turned to face the door, her plump ass cheeks filling my vision while he straddled my pelvis.
She hovered over me, unabashedly giving me a view of her puckered pink asshole and dripping pussy. She'd scooped up my cock again and was turning it this way and that, as if inspecting it for faults. She seemed satisfied because I heard her say to herself, "Yes, this should do nicely." Then, squatting, she angled my cock upwards beneath her. With no more ceremony, she lowered herself and, with a soft cry, impaled her slippery sheath on my baton-hard length of meat. It was as if a bear trap made of flesh had just snapped shut on my length. Her body poured over mine like it was melted butter. Her pussy felt like it was drawing me in with the same suction as her mouth had earlier. She let out a pleased sigh of relief as she finally settled herself down in a reversed cowgirl position on my lap, my cock buried in her so deep I worried for the state of her unborn child.
I let out an "Oof!" as Janey, never one to linger, wasted no time in popping her ass up and slamming back down on me like a beaver tail. She placed her hands on her knees for leverage and started a hypnotic twerking marathon with my pole at the center. I watched, completely mesmerized as her firm butt cheeks clapped together with each descent onto my cock. Her back muscles, already strengthened from carrying the extra weight of my niece, rippled with the exertion of her pop-and-thrusts. Her tiny crinkle of an anus winked at me each time her cheeks parted. My cock felt like it was in an experienced milkmaid's hands. My sister's sheath fit so perfectly you'd have thought it was tailor-made for me. The only thing that held me back from another shameful early climax was the knowledge of the beating it would most likely earn from her. I had to clench my teeth together until my jaw ached and bunch my duvet up into tight fistfuls to will back my simmering climax.
Fuck, my sister's vagina was good.
Jane was panting with pleasure, her tits slapping against my knees as she leaned further and further forward, seemingly trying to replicate the speed and force of the solar fusion process with just our two bodies. "Just... need... a...little... more," Each word was barked in time with the slapping of her ass on my crotch.
"Gah!" She threw back her head in exasperation and punched my knee hard enough to make me cry out. Any protest I had was cut off when she spun on me, nearly ripping my cock off in the process, a feral rage in her eyes. Now facing me, she shoved my cock back into herself in a most undignified manner and fell forward to grab the top of my headboard. "Play with my tits!" She commanded, dangling them pendulously in front of my face. I blinked a few times, wondered briefly if I had any objections, found I did not, and went for her dangling nipples like a trout for a fly. In the moment I was not bothered that they were still glazed with my own cum. Her nipples were twisted into tortured beads by her need. I took one between my teeth and stretched it to what had to be a painful length. But, all this did was earn me more grunts of pleasure from my sister.
My cock wrapped once more in her warm embrace, Jane wasted no time in returning to the punishing rhythm of before. I'd never been fucked with such anger and unquenchable lust before. It made all my previous vanilla sexual encounters seem tepid by comparison. She fucked me properly, making the most use possible out of my length and girth. Meanwhile, I fought valiantly under a barrage of swinging, slapping tits. I licked at the dangerously hard nipples as they came within range and caught great mouthfuls of flesh when I could. Soon her tits were reddened and tacky from my attention. My headboard cracked loudly against my wall as Jane screamed out, "Yes!...fucking...Yes!...Don't...fucking...stop!"
Sensing that things might finally be to her incredibly discerning standards and, knowing I was already dangerously past the safety margin for withholding my climax, I risked a little innovation, hoping it would push her over the edge. I grabbed her tits in my hands, squashing them together and pulling them down. I sucked one nipple into her mouth, lashed it furiously with my tongue, and then switched to the other. I did this on repeat while I bent my knees and used the leverage to start jackhammering up into her with the same force that she was striking down on me. The net result was that Janey was practically flung into the air with each thrust, Her head flew back and she yelled up at the ceiling. This was probably not recommended in any of her many mother-to-be manuals. If our parents had arrived home then they would have thought the house was being demolished by a team of howler monkeys.
