Male omegas have both penis and pussy, though their balls are absent. Their penises are smaller than alphas, and even betas. Their penises can cum like before, but sperms would be absent—it can work as a lubricant too. As for male alphas, they work as normal men in the normal world—I am not saying same as they have 'alpha' properties.
Female alphas have dicks along with balls, and female omegas are like normal female with 'omega' properties.
Sweat slicked our bodies, her breasts heaving with exertion. I could feel her knot starting to swell at the base, pressing against my entrance with each thrust.
"Not yet," she groaned, fighting it, but her body betrayed her. The knot inflated, catching on my pussy lips before popping inside with a lewd squelch.
I cried out as it locked us together, the pressure immense, stretching me to my limits. Elaine collapsed forward, her weight pinning me as she ground her hips in shallow circles.
"Elaine... ahh..."
Her cock pulsed inside me, hot spurts of cum flooding my depths. The knot throbbed, sealing every drop, tying us in this unwilling union.
"Goddamn it," she hissed through gritted teeth, her face buried in my neck. I could feel her teeth grazing my skin, the mark hovering on the edge. But she pulled back at the last second, reluctance winning out. "Not... not yet."
We stayed locked like that for what felt like hours, though it was only minutes. Her knot kept her buried deep, cum leaking around the seal as my pussy milked her dry.
My own penis leaked pre-cum onto my belly, untouched and aching, but the fullness in my core overshadowed it.
When the knot finally deflated, Elaine pulled out with a wet pop, a gush of her seed spilling from my abused pussy. She rolled off me, chest heaving, avoiding my eyes. "That wasn't... I didn't mean to knot so soon."
I sat up gingerly, thighs slick and trembling. The ache between my legs was a reminder of what we'd done, but the mark was missing. "We need to finish it," I said, voice hoarse. "The second time. Mark me then."
She shot me a glare; frustration etched on her features. "You're pushing it. This is already a mess."
But she didn't leave. Instead, she pulled me against her, our bodies sticky and spent. We lay there in silence, the air thick with the musk of sex. Reluctance bound us as much as her knot had, neither willing to admit the undercurrent of need that lingered.
Time blurred. An hour passed, maybe two, as we dozed fitfully. But her scent kept me on edge, my pussy clenching emptily, craving more despite myself.
"Why do you have so less stamina?" I mocked her.
She stilled before glaring at me. "I can't muster to fuck you because I don't love you. My mind is rejecting you."
"My mind doesn't ant your dick either. I have a royal pussy which is in great demand among a lot of alphas."
"You!"
Elaine stirred first with an angry face, her hand sliding down my side, fingers brushing my hip.
"Can't believe I'm doing this again," she muttered, but her cock was already hardening against my thigh. She flipped me onto my stomach, yanking my hips up. "Ass in the air."
I complied, knees spreading on the mattress, pussy exposed and dripping anew. The position felt degrading, but the cool air on my slick folds only heightened the sensitivity. Elaine knelt behind me, her hands gripping my ass cheeks, spreading them wide. Her tongue darted out unexpectedly, lapping at my cum-filled pussy.
I moaned, pushing back against her mouth. Her tongue thrust inside, scooping out her own release mixed with my slick, the sensation filthy and overwhelming. She sucked on my clit, teeth grazing my cute penis as it dangled below, sending shocks through me.
"Elaine... please," I begged, hating the desperation in my voice. Elaine gave me a mocking look.
"You omegas can beg only for the alphas' dicks, right?"
"Just do what I asked you to do!"
She rose, cock slapping against my ass. "You want it? Beg properly."
"Don't be despicable!"
"You want it or not?"
"Fuck me," I gasped. "Knot me again. Mark me."
The words unlocked something in her. With a roar, she slammed into me, her thick cock spearing my pussy in one brutal stroke. I screamed, the angle allowing her to go deeper, hitting my cervix with each punishing thrust.
Elaine fucked me like a beast, hips pistoning, her balls smacking my clit. My penis rubbed against the sheets, friction building as she railed me. "Tight little omega pussy," she growled, slapping my ass hard enough to leave a mark. "Taking my cock so well, even if you don't want to."
"Your alpha penis is okay too... ahhh..."
"Just okay?"
I didn't—did I? The lines blurred as pleasure coiled tight in my belly. Her knot swelled faster this time, battering my entrance. "Yes, now... knot me," I whimpered, traitorous words spilling out.
It locked in with a pop, her cum erupting in thick ropes, filling me until it leaked down my thighs. Elaine's teeth found my neck, sinking in deep as she marked me. The pain was exquisite, bonding us in blood and heat. I came hard, pussy spasming around her knot, my own penis spurting cum onto the bed.
We collapsed together, knotted and claimed. Her bite throbbed, the alpha mark sealing my fate as her omega—for the time being. Reluctance lingered, but in that moment, it didn't matter.
"I don't like you... I didn't want to m-marry you..."
"I don't you like you either."
"Can you... clean me up?"
"Our deal is over now. I don't have any interest to clean you up."
"At least, have some... decency..."
"No."
I shook my head slightly. "Then, go and sleep on the couch. I... don't w-want you in m-my bed..." My eyes were closed due to the sheer amount of exhaustion I was feeling.
"What?!"
"... Our deal is over, right? Just go..." I whispered.
