Summer had arrived with a vengeance, and I'd just celebrated my birthday, making me the same age as my cousin Gwen. Visiting her family for vacation was about to be a real rollercoaster ride. One afternoon, as I strutted into the backyard, I found Gwen sunbathing by the pool in a cute bikini that made my heart skip a beat. My heart raced like mad, and I felt a forbidden attraction to my own cousin. The sight of her sun-kissed body was like a magnet to my eyes, but when she got up to join me in the pool, I noticed something that made my jaw drop. There was a mysterious, massive bulge in her bikini bottoms, like she was smuggling a goddamn anaconda. In my innocence, I was puzzled as hell, wondering if she might be rocking the same equipment I had in my own pants.

A couple of summers later, I found myself back at Gwen's place, and holy shit, she had transformed into a goddess. Her hips were like a Kardashian's, and her ass had blown up like a damn zeppelin, making her figure jaw-dropping. Those once-flat boobs were now small, round orbs, with nipples poking through her tight shirt like they were saying, "Hello, Ben!" Even her abs were on display, and I was salty as hell that she had a washboard abs while I was stuck with nothing of the sort.

When Gwen went in for a hug, she was like an Amazon, towering over me like a skyscraper. I was both scared and envious of her height. She squeezed me like a python, and I felt something thick and hard poking me from her crotch. It had to be a cock, right? Did her growth spurt make that grow too? The thought of her packing a bigger package than me was both humiliating and weirdly thrilling.

Gwen seemed to love watching me squirm and took every chance to tease me about my height and my less-than-stellar physique. When we hit the pool, she stripped down to her swimwear, showing off her sculpted body, and I couldn't tear my eyes away from her abs. A storm of jealousy and desire raged inside me.

I was determined to make a statement, I challenged Gwen to an epic arm-wrestling match, seeking redemption for my pitiful lack of growth. Our intense battle had us both sweating' like pigs, muscles bulging, and faces red as we fought for total domination. With my heart hammering in my chest like a wild beast, I finally nailed that victory by a hair's breadth, restoring my goddamn pride.

Fast forward a few years. As I strutted up to Gwen's house, I couldn't help but gloat that I'd finally grown taller than her fine ass. Gwen, on the other hand, had barely shot up an inch, but she'd sure as hell grown in all the right places. Rocking a more mature wardrobe, she ditched those skimpy outfits, but no amount of fabric could hide that smoking hot body. As we played cards, I couldn't take my eyes off her glorious, bigger boobs and toned muscles, making it damn obvious she'd been hitting the gym. She was like a sultry secret weapon, just waiting to be unleashed.

One day, I finally managed to coax Gwen out to the pool, hoping to see her in a sexy bikini and catch a glimpse of her smoking hot body. She came out, but much to my dismay, she had a swim top and shorts on, lounging on the daybed with a damn book. I tried to convince her to join me in the water, but she was more interested in her reading. Desperate, I challenged her to a jump-and-dive competition, knowing her competitive streak would kick in.

Gwen stripped off her shirt, revealing a jaw-dropping, six-pack sporting hourglass figure. Her boobs strained against her bikini top, practically begging for freedom. She dived in, losing her shorts in the process, and I couldn't help but sneak a peek at her luscious ass underwater. And holy shit, there was something massive flopping around between her legs. I tried to play it cool and surfaced, hoping she didn't catch me ogling her junk.

Gwen was mortified when I told her she lost her shorts. She scrambled to put them back on and dashed off to take a shower. I was lounging by the pool when I got a Snapchat from her. I could hear her giggling in the bathroom upstairs. I opened the snap, and there she was with a caption: "OMG, I'm pretty sure Ben got a glimpse of my secret and asked about it. Do I spill the beans?" Poor Gwen must've sent it to me by mistake.

That evening, we were chilling in front of the TV, Jenga tower precariously wobbling on the coffee table. I couldn't help but bring up the saucy Snapchat Gwen had sent me, the one that got me all hot and bothered. Gwen, the sexy, confused fox, looked like she wanted to crawl into a hole when she realized she'd accidentally sent it to me instead of her BFF. I teasingly prodded her to spill the beans, but she got all blushy and squirmy. That adorable hesitation was adorable and drove me nuts. She muttered "it's nothing," but I knew she was dying to spill her dirty little secret. Then, to my disappointment, Gwen bailed to read some novel in bed, leaving me high and dry. The next day, my family and I were leaving, so I never got the juicy deets on her secret, and the sexual tension was left to simmer.

A year had flown by faster than a frat boy chugging a beer, and there we were, fresh grads. My girlfriend and I were visiting Gwen, who was home alone. Gwen and I had our sights set on the same university, so I pitched the idea of living together to save some money. My girlfriend was going be living a couple hours away, and we sure as hell didn't want to drive that far each day, so living with Gwen seemed like the good idea.

When Gwen swung the door open, I could feel my heart thumping in my chest like a goddamn jackhammer. She looked drop-dead gorgeous, and her boobs were slightly bigger than the epic proportions they were the last time I laid eyes on her. We said our hellos, and my girlfriend and I headed to the spare room to unpack our bags. Gwen, being the sly minx that she was, poked her head in and casually mentioned she was off to the garage to pump some iron during her usual workout, but she'd be available if we needed anything... or anyone.

As my girlfriend hogged the bathroom for an eternity, I made myself a badass sandwich and plopped down on the couch to watch some TV. Suddenly, Gwen, my smoking hot cousin, burst from the garage like she'd just run a marathon, sweat dripping from her brow. Her full-length tights and gym shorts clung to her toned body, while her loose shirt left just enough to the imagination. "Hey, you watching some old-ass Top Gear episode?" she asked, teasing me.

"What kind of twisted game are you plotting?" I replied, my curiosity piqued.

"I bet my fine ass can do more push-ups than you," she boasted, flexing her muscles.

"Bitch, please," I scoffed, confident I could take her down.

"If you win, I'll let you give me a back massage," she said, winking.

"And if you win?" I inquired, my mind racing with possibilities.

"You give me a full-body massage," she grinned, her eyes filled with mischief.

"Damn, that's not fair," I whined. "I have a girlfriend, I can't just give you a massage."

"Aw, are you scared of losing to your smokin' hot girl cousin?" she teased, poking at my ego.

"Fuck no," I replied, irritation creeping in.

"Fine, but if you win, you give me a back massage first," she demanded. "And I'll return the favour after."

"Deal," I agreed, ready to annihilate her in this challenge.

As Gwen and I started pumping out push-ups, my heart was pounding like a goddamn jackhammer. My competitive fire raged, and I was hell-bent on winning. We hit 20 push-ups in sync, and I began to slow down, feeling the burn. I glanced at Gwen, who was still going strong like the goddamn Energizer Bunny. At 40 push-ups, my arms quivered like Jell-O. I was sweating balls, unsure if it was from the workout or the thought of losing to my cousin. She must have been feeling the heat too, but as we hit 50 push-ups, she was still banging out two for my every one. The sexual tension was palpable, and I couldn't help but wonder if she'd actually kick my ass.

As the push-ups continued, my thoughts went haywire. The bet was off the fucking charts, and I realized I'd totally neglected to haggle over what she'd get if she won. As I lay there, sweaty and defeated, Gwen kept pumping out perfect push-ups, her muscles flexing and glistening. She finally stopped and said, "Boom, 200 dweeb. I could keep going, but I did just do a workout before this." I was simultaneously turned on and pissed off. "Beaten by a girl, dweeb." I said, "But how?" She said, "Feel my rock-hard abs, you loser."

As she yanked her shirt up with one hand, she used the other to grab mine and guided it towards her rock-hard abs, like freakin' chiseled marble. My body responded instantly, and I could feel my excitement growing. I ran my hand up her insane six-pack, each ridge as defined as a goddamn mountain range. Gwen then let out a laugh, saying, "Jesus, I smell like a gym locker. Time for a shower. You better kick your girl into gear, or we'll miss our dinner reservation."

Gwen's cocky smirk was burned into my brain as I stood there, feeling like I'd just been bitch-slapped by reality. I'd always been the strong one, but she'd just flexed on me like a boss. My ego was battered, and my body was on fire with lust. The tension was so thick at dinner you could cut it with a knife, and I couldn't help but sneak glances at her when my girlfriend wasn't paying attention.

After stuffing our faces, we headed back to Gwen's pad. It was late, and my girl was already sawing logs beside me in bed. But my mind was racing like a goddamn NASCAR event, replaying the day's events. I couldn't shake the feeling that Gwen had played me like a fiddle, and my body was throbbing with desire. Just when I thought I was going to lose my shit, my phone buzzed. It was a Snapchat from Gwen, featuring a pic of her glorious, peachy ass in her PJs, along with the message, "What's the holdup, stud? Massage time!"

I strode towards Gwen's room, feeling like a horny teenager, a bizarre cocktail of exhilaration and anxiety sloshing around inside me. My heart thumped like a drum solo at a rock concert, while my pants threatened to burst at the seams. I knocked on her door so softly I barely heard it, and she called out, "Just come in, dumbass! It's not like I can get up!"

"What's the matter, you okay?" I asked. As soon as I entered, my eyes locked onto Gwen's topless body sprawled face-down on the bed like a Playboy centerfold. I'm pretty sure my jaw hit the floor, and I was like, "Holy shit, this is happening!" Gwen beckoned me with a seductive finger curl, "Get your ass over here, Ben."

After a moment of hesitation, I closed the door and ambled towards the bed like a moth drawn to a sexy flame. "Chop-chop, dweeb," she teased, "Straddle me and give me a back rub." My mind raced with curiosity and excitement, while I tried to play it cool.

Gwen cocked her eyebrow and said, "Sit your fine ass on top of me, and let's kick this shit off with a back massage." I shot back, "Hold up, what do you mean by 'starting' with a back massage?" I could feel a rush of excitement and nervous energy surge through my body, like I was about to ride a rollercoaster of pleasure. Gwen's sexy smirk taunted me, promising things I could only dream of. "C'mon, Ben, you signed up for the full-body treatment, didn't you?" she teased, her voice dripping with innuendo. "You better buckle up, 'cause I've got a whole lotta surprises in store for you, big boy."

As I climbed onto the bed and slid my ass next to hers, the knot in my stomach grew tighter than a virgin on prom night. This was some wild shit, and I couldn't believe it was actually happening. Gwen saw me trembling like a leaf and laughed. "Chill, Ben. I'm not gonna bite... hard," she teased, making me blush like a ripe tomato.

I started to give her back a massage, my hands exploring her silky-smooth skin, which made me think of a perfectly glazed donut. Gwen playfully rolled her eyes and said, "Seriously, dweeb? I told you to sit on me, not beside me. I want a legit back massage, Ben." I hesitated, thinking, "WTF?" but the mischievous glint in Gwen's eyes was like a fucking green light at a drag race.

So, I straddled her firm, powerful legs, giving me the best view in the house. It was sensory overload, and my crotch responded like a rocket about to blast off. Positioned like that, I had a front-row seat to her curvaceous body, her toned muscles, and the ridiculous strength in her arms, back, and booty. And those sweater puppies, holy hell, they were practically begging to burst free from beneath her.

Ben's hands hovered above Gwen's magnificent boobage, his palms barely grazing the sides of her fleshy pillows. He felt like an explorer discovering uncharted territory. Gwen cocked her head and teased, "What's the matter, Benny boy, cat got your tongue?" A lump formed in his throat, and he squeaked, "Nothing." Trembling like a nervous schoolboy, he began massaging her back.

As he kneaded her taut muscles, Ben was surprised at the iron-like hardness beneath her smooth skin. He couldn't help but admire Gwen's physical prowess, but his hands were beginning to feel like they'd been through a medieval torture device. He paused, rubbed his hands together, and chuckled to himself, "Jesus, Gwen, you're like a sexy Terminator."

In the silence, he thought Gwen had dozed off. As he started to leave, a sudden snore like a chainsaw ripped through the air. Gwen rolled over, her curvaceous form exposed, tits like ripe melons spilling out. His heart raced, and he thought, "Fuck, she's hot."

Gwen's eyes fluttered open, and she smirked, "Like what you see, perv?" Ben's gaze locked onto her cleavage and chiseled abs, and he muttered, "Uh, yeah, I mean...no, I mean..." The sexual tension between them could've cut glass.

"I was just about to take a break," I replied, attempting to sound casual as fuck.

"Well, don't stop now, big boy. You were doing a fantastic job," she said, giving me a sly, devilish grin. My cheeks flushed with heat like a goddamn tomato. The sexual tension in the room was as thick as molasses, and I could feel my arousal reaching levels I never thought possible.

As I climbed on top of Gwen to rub her chest and stomach, I felt something poking my ass. It was hard and elongated, like a fucking cucumber. Gwen's expression morphed into worry and fear. "Wait, stop!" she blurted out, trying to cover it up. "Is that a girl-cock, Gwen?" I couldn't resist teasing her, barely holding back laughter. She pushed me off and quickly pulled up the blanket, attempting to play it off, "What? No! You must have just felt my phone in my pocket on my leg, dumbass." But I knew she was full of shit. Her phone was on the bedside table, and my curiosity about that goddamn bulge intensified. I couldn't help but wonder if she was hiding a secret toy or maybe even a hermaphrodite.

So there I was, dying to expose Gwen's dirty little secret. Was it a massive schlong? A monstrous dildo? My mind was filled with filthy fantasies. I couldn't help it - I slid my hand down her rock-hard abs, aiming to discover the truth. But just as I was about to crack the case, Gwen yanked my hand away. "What the actual fuck, Ben?" she snapped, a look of confusion and annoyance plastered on her face. "Well, I've always thought you might be hiding something...extra," I stammered like a total dipshit. Gwen rolled her eyes, obviously pissed off. "Fine, check it out yourself, you perv," she said, releasing my hand. With my anticipation hotter than a pornstar's pants, I resumed my naughty quest, venturing down her ripped stomach and into her night shorts. As I groped around, I felt nothing but a moist patch on her panties covering her luscious pussy lips. No sign of the elusive, elongated object that had haunted my fantasies. Fucking hell. Then, Gwen dangled a purple massage wand in front of my face, smirking. "Looking for this, dumbass?" My heart dropped like a lead balloon. No giant cock, no sex toy - just a damn massage wand.

Ben was starting to question his life choices. "Goddamn, this is getting weirder by the second," he thought, feeling flustered as hell. Gwen couldn't help but notice his inner turmoil, so she asked, "What's the matter, dweeb? You seem more fucked up than usual." Ben swallowed hard, his face redder than a damn tomato. "Well, I kinda hoped that bulge in your bikini was, you know, a massive dick. I mean, with your badass attitude and all, it made sense in my head. I wanted to whip mine out and see if you could put me to shame. But now that I know it's just a regular ol' vagina, I'm a bit let down." Gwen just looked at him and laughed. "Ben, you horny dumbass, I'm all woman. But if I had a cock, you better believe it would be the stuff of legends."

Before Ben could even process that, Gwen was already plotting her next tease. "So, you're into chicks with dicks, huh? That's a new level of pervy even for you, Benji." Ben stumbled over his words, feeling exposed and vulnerable. "I... uh, it's not like that, I just... thought it'd be hot, you know?" Gwen just smirked and shook her head, clearly enjoying the upper hand. "Well, who knows, maybe in some alternate reality, I'm rocking a monster schlong and you're begging for mercy."

Gwen's words sent Ben's mind reeling. He couldn't help but feel aroused by the thought of measuring up to a girl's cock. Gwen, sensing his weakness, went in for the kill. "So, it doesn't bother you that in your little fantasy, I've got a bigger dick than you?" she teased, raising an eyebrow. Ben tried to play it cool, but his voice cracked like he was going through puberty all over again. "N-no, not at all. In fact, I'm kinda bummed you don't have one." Gwen just raised her eyebrows and gave him a devilish grin. "Oh, really? Well, that's good to know, Ben. Maybe we can explore that some other time..."

I thought, "Okay, that's enough of this kinky shit for tonight. Time to hit the sack." I sprang up and bolted out of Gwen's room and into the hallway. But just as I closed the door, I caught a glimpse of Gwen diving into her ensuite like she was in some sort of sexy spy movie. The whole wand situation boggled my mind. Like, how the fuck did it poke me like that? I knew I had to investigate, so I sneaked back into her room and crouched down to peep through the keyhole of the ancient bathroom door.

And there she was, Gwen in all her naked glory, legs spread wide, yanking on something right in front of her. I couldn't quite see what it was, but I heard her moan softly and whisper, "Oh, Ben..." I almost choked on my spit as a massive balloon-like thing began to fill with some gooey white stuff, bulging between her legs.

"Holy fuckballs," I muttered, "Is that a goddamn condom? Is she jizzing into it?!" My jaw hit the floor as the condom swelled up like a cursed water balloon. Gwen finally slowed down, the condom filled to the brim with enough spooge to fill a beer mug. She tied it off, yanked up her PJs, and left the bathroom. I hauled ass out of there and jumped back into his bed, heart pounding.

Moments later, Gwen poked her head into my room, and I had to think fast. So, I pulled a classic move and faked sleeping like a goddamn Oscar-winning actor.

The next morning, I woke up to the sound of my girlfriend's soft footsteps as she got out of bed. I rubbed my eyes and looked at the clock, it was way too fucking early. My head was throbbing from all the talking and massaging Gwen and I did the night before. I decided to stay in bed and try to catch some more z's. As I closed my eyes, I couldn't help but think about Gwen's incredible physique. My mind was flooded with images of her toned abs, perky boobs, and that mysterious bulge in her bikini bottoms. I wondered what it could be, perhaps she was hiding a secret weapon in there or something. The more I thought about it, the more curious and horny I became.
