I finished rubbing my sister, before deciding to go and take my mother. My tail propels me through the water easily, as I glide to where she lays, basking in the aftermath of her orgasm. She lay there, chest heaving as her breasts heaved with her, face flushed. My cock, hard from just watching the show stood at attention at the sight of my beautiful mother lying naked beneath me.
"Jake, oh god why did you do this!" said Lauren as she tried to sit up. " I love you and your sister, but not like this!" She exclaimed as she glared up at me. Her body betrayed a different story. The aftermath of her orgasm to Anna's ministrations was still obvious, and even now her eyes were drawn to my raging erection.
"Ah but you admit you do love me." I said as I began to caress her cheeks. Her breath hitched with pleasure, as her enhanced sex drive started again.
"I love you Jake, but as my son! You can't do this to me, to your sister!" She exclaimed. "We cannot do the things you've done to us, we are the same blood!" Lauren pleaded.
I moved my hand down to her breast. "Can I not suck on your tit mom? Did I not do that already?" I licked around her nipple, watching as she twisted in pleasure, watching with a mix of horror and anticipation. I bent and took it in my mouth, rolling it around in my teeth as I sucked on my moms tit. I bit down gently, watching a moan escape her lips as she panted. "I am your son mother, is this not natural?" I asked her.
"No" Lauren said between gasps "this is not supposed to be like this!" I smile and continue sucking, alternating tits. "Oh god!" She moaned. "I am your mom Jake, we aren't supposed to do this, these acts, that's not the love we share!" She pleaded.
"What acts mom" I said as I reached one hand to stroke he cheek. The other wrapped around my dick, still rock hard. "Do you mean my hand in your pussy? "I said as I moved fingers into her, watching her arch her back in unwanted pleasure. "Or do you mean when my dick was in Your pussy?" I said as I rubbed my dick on her very wet, even underwater slit. "I think that as your son I have more right to your body than anyone!" I said as I looked at her. "I have the right to make you mine, body and soul."
"Listen to yourself Jake!" Lauren pleaded. "You sound crazy! We can't be lovers! I'm your mother! You came from my womb, you can't fill it! This is incest Jake! I won't do it!" She claimed. I smiled as I moved in, hovering right over her face as we stared one another in the eyes.
I leaned forward, holding her cheek in hind hand as she glared at me. "Lauren, I love you, as my mother, and as a lover." I watched as her breath hitched. "I'm going to take what is rightfully mine, I'm going to fuck your pussy with my dick, your sons dick. I'm going to stick it in you and fill your womb with my seed. I'm gonna knock my mom up. This isn't wrong, just me taking my right as a man and fucking my beautiful mother, now my mate." Her face grew more horrified at each word. "Don't you see mom!, feel how our love is true!"
I moved my lips to hers, diving my tongue in to
Play in her mouth. It danced around, ignoring her surprised and repulsed face, but as we locked lips, she was horrified to discover how right it felt, how my tongue in her was so natural. Before she knew it, she had locked her tongue in a battle with mine, as we kissed. Our arms wrapped around each other, and a sense of rightness resonated through her.
She pulled her face away. "Jake" she moaned, "this is so wrong, I shouldn't feel these things for my son" she said. I moved my arms so I could cup her breasts, and kissed her neck, moving slowly down her collarbone, watching her gasp and moan, shreds of inhibition falling.
"Just say it mother, say what you want, you know this feels right" as I caressed her body, watching her moan in pleasure. I moved my dick to rub against her entrance, causing her to gasp and grab my shoulders with her hands. "You know what to say" I said to her.
Her eyes closed as she breathed in and out, caught in indecision. Seeing my chance I rubbed my tip on the top of her cunt, sending waves of pleasure through her body. Her eyes snapped open. "I love you Jake! Oh god I love you, I love you as my son but as my lover, god please fuck me, I want you so bad, I want you to fuck your mom, fill my womb with your seed!"
I moved my dick into her, watching as she shuddered as it went deeper and deeper inside. Her eyes rolled back, and I saw her last remorse over out sin leave her. Our tails wrapped together, and I began to buck inside her.
"Oh god, oh GOD, OH GOD YES!" She screamed as she rode my mermaid cock. "Why did I not want this, this paridice!" She bounced up and down, breasts bouncing with her. "Please, never stop fucking me, never stop fucking your mom!" Lauren screamed as I fucked her. I watched her jerk in my arms , as the first of multiple orgasms hit her. I felt my own rapidly approaching, the sight of my mother in my arms giving into my will was incredible.
"Mom, I'm gonna cum, gonna cum right in you, knock you up!" I screamed.
"God, do it, do it baby, I my sons cum in my womb, I need it now!" She shouted as she reached another peak.
I let go of my orgasm, feeling the pleasure of dumping it into her pussy, moms pussy. She laid there, in shock as bits of cum floated out of her cunt. She looked briefly horrified, then settled into contentment. My mate was finally mine, in all ways.
