It was a hot summer evening and I was lounging around my stepmom Jenna’s house while my dad was away on a business trip. At 19, I had moved out this spring to attend university, but was back for a few weeks of summer break before returning for my sophomore year.
Jenna had gotten married to my dad a few years ago when I was 15. The age difference between them was notable – dad was in his early 50s while she was still in her wild 20s. But they were head over heels for each other and that’s all that mattered. Plus, it was pretty sweet to have a hot young stepmom around!
I was in the living room playing video games when Jenna came sauntering in wearing nothing but a skimpy pink bikini that perfectly showcased her curvy, tanned body. Her narrow waist formed a striking contrast with her round, jiggly ass cheeks that looked like they might spill out of the tiny bottoms any second. I gulped as I got an eyeful of her phat booty and tried to act nonchalant.
“Hey sweetie, how’s it going?” she cooed in her bubbly voice. “Want to come skinny dipping with me in the hot tub? It’s the perfect night for it!”
An idea suddenly popped into my head. I’d been fantasizing about taking my stepmom’s ass for a while now. What better opportunity than this to finally make my move?
“Oh um, sure! I’ll be out in a sec,” I replied. Once she left for the back yard, I quickly stripped off my clothes and wrapped a towel around my waist to conceal my already hardening cock. I made my way out to the deck.
Jenna was already soaking wet in the jacuzzi, her bikini top floating on the water, fully exposing her large, perky tits. “Mmm, that feels so good!” she purred, arching her back. “Come join me, baby boy!”
I stepped out of my towel and slipped in across from her. The sensation of the warm, bubbling water against my bare skin felt amazing. But even better was the sight of my stepmom’s incredible naked body, dripping wet and glowing under the moonlight. I couldn’t take my eyes off her.
“Like what you see?” Jenna asked with a flirty smile, noticing my lingering gaze. She placed a manicured hand on my thigh under the water and gave a little squeeze. I jumped at her touch.
I decided it was now or never. “Jenna, can I tell you something?” I asked, my voice cracking slightly. “I’ve been thinking… I really want to fuck your tight little ass. To slide my big hard cock deep into your tight rear entrance until you’re screaming my name.”
Her eyes went wide for a moment before she let out a surprised little laugh. “Oh my god, baby boy! I had no idea you thought of me that way.” She stroked my thigh again, this time moving further up. “Well, we wouldn’t want to disappoint such a horny young man now, would we?”
Jenna got up and climbed on top of me, straddling my hips. She ground her hot, slippery ass against my rock hard erection, coating it with her juices. “Mmm yeah, you feel so big and hard for me,” she moaned. “I want you to start by worshipping my ass with your tongue. Get it nice and wet for your cock.”
I gladly obliged, spinning her around and burying my face between her bubble butt cheeks. I lapped and sucked at her puckered hole, savoring the musky taste of her most intimate area. “Oh fuck yes, eat my asshole just like that!” Jenna cried out, pushing her booty back against my mouth.
Once I had her hole nice and slick, I grabbed her hips and lined up my throbbing tip with her tight rear entrance. Slowly, I pushed forward, spreading her open and sinking into her velvety heat inch by glorious inch.
“Ungh, your cock is so big! It’s stretching my ass so wide!” Jenna whined as I bottomed out, my heavy balls resting against her clit. I gave her a moment to adjust before I began to move, pulling nearly all the way out before thrusting back in.
We quickly fell into a hard and fast rhythm, the wet smack of skin on skin filling the air. “Yes, yes, yes! Fuck my tight little ass! Pound me with that huge dick!” Jenna squealed with delight, slamming her hips back to meet my thrusts.
I grabbed a fistful of her wet hair and pulled her head back, hammering into her even harder. The sight of her round tits bouncing in the moonlight, combined with the incredible feeling of her tight ass squeezing my shaft, was almost too much to handle.
“Fuck, I’m gonna cum!” I grunted, my thrusts becoming erratic. “Where do you want it, stepmom? Want me to fill your tight ass with my hot load?”
“Yes baby, give it to me! I want to feel your cum deep in my ass!” Jenna begged, her pussy juice gushing out and mixing with the jacuzzi water. With one final thrust, I buried myself to the hilt and exploded inside her, pumping what felt like a gallon of semen into her hungry hole.
Jenna let out a scream of pure ecstasy as she too reached her peak, her asshole clenching down on me rhythmically while I emptied my balls into her. We collapsed together into a sweaty, satisfied mess, my softening cock still planted firmly in her cum-filled ass.
“Ungh, that was amazing,” I panted, slowly pulling out of her with a wet pop. Jenna just moaned in response, too fucked out to form words.
As we lay there in the afterglow, a thought occurred to me. If this was how amazing sex with my stepmom felt the first time, I couldn’t wait to see what other naughty adventures the future might hold. With Jenna by my side, I knew every day was going to be a wild ride.
