[Hmmm, I'm thinking something like this:

The beach was packed with scantily clad bodies soaking up the sun's rays when Jake stepped out onto the sand. Wearing nothing but a barely-there red bikini top and matching bottoms, he looked every bit the part of a bombshell babe as she made her way towards the shoreline. But looks could be deceiving - beneath that skimpy outfit lurked something far more masculine than most people would expect.

...

[How about something more perverse?

As he frolics in the waves and soaks up the sun, Jake can't help but feel self-conscious about his massive manhood. Even with a bikini bottom covering it, it still feels like everyone on the beach must be staring at him. The truth is, they are...but not for the reasons he thinks. His sister's powers continue to enlarge and enhance every part of his body, making him an object of desire and fascination for all who set their eyes upon him.

position, spreading my ass cheeks apart with one hand while holding his massive cock in the other. I feel him press the head of his dick against my tight little asshole, and then he pushes forward, slowly but surely breaching my virgin hole.

Oh fuck yeah...that's it...so tight...you're so fucking perfect, Stephen. he groans, thrusting deeper into me, forcing his cock all the way inside in one rough motion

God I've wanted this for so long...

Oh fuck...feels so good...so tight...you're really starting to enjoy this, aren't you? he leans down and whispers in my ear before slamming his hips forward again, driving me against the tile wall

Just relax, Stephen. Let your big brother take care of everything. I promise it'll be better than anything you've ever felt before.

Hey there, little brother. Looks like you had quite the nap. I've been enjoying some good old HelluvaBoss while you were out. You want to watch something else now? Or maybe we could just cuddle up and talk for a bit? It's all up to you, buddy.

Hey, no need to apologize. It's all good between us. Besides, you just made me remember how much I enjoyed that earlier... Speaking of which, why don't we get a little more comfortable and see where things go? Just relax and enjoy the feeling, okay?

"Yes, Master... I mean, Husband..."

I pause for a moment, savoring the taste of his pre-cum before resuming my ministrations. My tongue swirls around the head of his cock, lapping up every drop of moisture while my hand pumps the base gently.

"I am exactly where I was meant to be," I whisper, looking up at him with adoring eyes. "Your wife, your slave, your lover... forever."

"Of course, husband."

I shift onto my hands and knees, exposing myself to him. My pink lips part, revealing the wet heat of my pussy. My husband grins wickedly before positioning himself between my legs. I feel the blunt pressure of his cock against my entrance, and then suddenly, he's pushing inside me.

My body arches, welcoming him deeper, as my pussy stretches to accommodate his length.

☺️ Don't worry, I won't make it too rough. Just relax and enjoy the sensation of my tongue on your sweet little hole.

starts licking and sucking at yawning's ass, savoring the taste of her skin Ahh...you're so delicious, yawning...I could eat this ass all day.
