Traveling down her hot skin, my hands stopped several inches below her swinging breasts. Spreading my fingers out, they sunk between each rib and squeezed tight. I could feel her heart pumping at an elevated rate. Stopping my hip movement, I fucked her by pulling her back and forth, using her ribcage as leverage. Her mini-orgasms didn’t satisfy her lustful cravings, her moaning growing louder. Her globes of succulent tit flesh swung back and forth, colliding with Rachel’s torso while she attempted to suck milk out of her sister’s nipples.
Fearing I was going to bruise her body, holding her so tight, I brought her pelvis back to collide with my groin. Buried to the root, I stopped fucking her to catch my breath and calm down before elevating her to a major orgasm.
Bringing my hands down to her pelvis, I gripped her hip bones. Stroking gently in and out, I admired the view of our coupling. Her curvy body enhanced her beautifully smooth flesh. My prick was white and frothy from our mixed juices. Looking below my coated cock, I noticed Rachel’s pussy open and wet, also quivering with excitement. Moving up closer so I could go deeper, I fucked her faster. Changing my pace, I thrust in the first few inches, withdrew, and rapidly thrust back in. I repeated a dozen times, then sunk my cock down to the bottom of her velvety sheath.
Her breathing rate and groans increased while I fucked her at a furious pace. I repeated the short, fast fucking, sinking to the bottom of her starving pussy every dozen strokes. Anticipating when my prick descended, she arched her back to facilitate deeper penetration. Her groaning turned to a whimpering sound when she stopped sucking on her sister’s tit, holding her nipple tight between her lips.
Her pussy vibrated and released more pussy juice, anticipating her major orgasm. Stopping my short stroking rotation, I fucked her slow and deep, hitting bottom each time. Even with her cavern full of lubricating sex juices, her pussy wrapped tight around my stiff prick each time it sank into her depths.
Halting my movement, I held her steady. My hard prick was firmly buried deep in her snug pussy. A feeling of empowerment swept through me. She wouldn’t thrust back because of my earlier teasing. She didn’t want to take the chance I’d pull out my cock, giving her so much pleasure. Less than a week ago, she was in total control as my mom. Now she was obeying her son like a sex slave.
During the pause, Mom murmured, “Please, Sam. Fuck me to a climax. Don’t tease me anymore. I want to feel your hot sperm fill my pussy. I’m going to cum on your big cock pretty soon, regardless. Please be kind to your mother and flood my cunt with your cum.”
Rachel piped, “Yes. My nipples can’t take much more. Please fuck your mother to an orgasm. Or if you want, you can put it in another willing hole.” I looked down to see my sexy aunt flex her hips, looking for a hard prick.
My eyes locked with Rachel’s while I reached down and jammed three fingers deep in her wet cunt, stroking in and out as she bucked with excitement. I answered, “Sorry, Rachel. This load is for my sexy mother.” I pulled my fingers out and held Mom again.
Feeling remorseful about teasing Mom earlier, I slowly pulled my shaft out to the entrance of her pussy. I swiped my head up and down her slit, rubbing it across her sensitive clit. Holding her tight, I popped my prick through her tight puffy outer lips and said, “Mom, it’s your turn to fuck me. Show your motherfucking son how much you want him. Fuck me the way you want it!”
Her hips flew back so hard that I barely held myself from falling backward. My hands held tight while she went wild, bucking and fucking her son as hard as she could. Moving her ass up and down while moving to and fro caused my prick to hit areas seldom touched. Releasing Rachel’s nipple to catch her breath, her groaning grew louder, using my cock to scrape along her sensitive walls.
Mom fucked me like I was the last man on earth. My breaths were short and rapid while my prick took a beating it hadn’t had to endure before. I wanted this to last forever, but hot blood surged into my cock, signaling my approaching orgasm.
I gripped her thighs and timed my strokes with her frantic humping. It wasn’t necessary to tell Mom I was ready to come when my prick expanded. Feeling her pussy and body tremble in anticipated excitement, I screeched, “Mom, your pussy is wet and tight. I can’t believe I’m fucking my beautiful mother. Don’t pass out this time. It’ll be our best orgasm ever. I’m filling my mom’s pussy with sperm!”
Hearing this, my aunt retorted, “You passed out fucking your son? Wow, you are one horny mother. And you call me a slut. Kiss me, you son-fucking slut.”
The two sisters locked their mouths together, fucking each other’s mouths. I held Mom tightly and fucked her hard. My helmeted head filled with blood, increasing my difficulty shoving in and out of her tight channel. My balls filled up, and it felt like they were trying to eject my entire reservoir of sperm at once. My shaft tunnel wasn’t large enough to allow for that much volume.
