"Hope you make me do something good," I say, surprised by the words coming out of my mouth. I blush but keep my eyes trained on Dom.
He raises an eyebrow in surprise, grinning at me. "Oh yeah?" he teases me. "I have some ideas."
I move away and start walking towards the beach house, throwing a look over my shoulder. "Can’t wait," I purr and wink at him.
Then I disappear inside the house, almost falling to the floor once I'm away from his watchful eyes. My breathing becomes ragged as I think of what I just did, but a smile finds its way onto my face, nonetheless.
I try to keep up appearances, so I decide I’ll head down to a bonfire party that evening. I just wear a dress over my bikini. My hair is air-dried from the sun with beachy waves, and I leave my face free of makeup, since my skin is already developing a nice tan again.
While I'm waiting for Susie, my phone beeps and I almost fall over in my rush to read the incoming text, hoping it's from Dom.
My wish comes true.
Are you coming to the bonfire?
Yep, getting ready now. Are you?
Yes. Wanna play a game?
Fuck yeah. I do want to play a game.
What kind of game?
Truth or dare?
There's already a smile playing on my lips as I consider my choice. Good girl Cassidy always goes for truth, but today I'm feeling brave, so I text him and ask for a dare.
Wear a dress tonight. No bra, no panties.
My eyes widen as I read his text, and I giggle, feeling both excited and scared. Slowly, I get up from the bed. I strip my bikini from underneath my dress, hoping the night will be dark enough to make the dress less see-through.
Done.
Pics or it didn't happen!
I laugh out loud at his message, then grab my bikini top and dangle it between my fingers, snapping a quick shot and sending it to his number.
I'll have to check in person, don't trust you.
Blushing, I reply.
That sounds like another dare, and I never got my turn. :(
It's my game darlin ;)
I don't want to admit it, but I can already feel the wetness between my legs, and I know I'm in big, big trouble. But tonight, I don't think I can resist.
My mind is telling me Adrian is the wise, safe choice. But my body wants Dom, and I'm in no position to deny it what it wants.
My cell phone beeps again.
Another one?
I reply, choosing dare and adding a smiling emoji as I sit waiting for his reply for ages. Finally, my phone beeps again and my fingers shake as I look at his text.
You're already wet… You're going to slide your fingers inside yourself the moment you stop reading this text. And then you'll lick them for me.
I can't believe how cheeky he is. And I can't believe what I do next.
My trembling fingers find the slit between my legs, which is drenched with my own juices. Hesitantly, I push two fingers between the folds and moan as the rush overtakes me, slipping them back out.
My whole body shakes as I lift my fingers to my lips, snapping a photo with my free hand. I close my eyes, tasting myself on my own fingertips.
I send it.
Then a car starts honking outside and I drop the phone like it's lava, blushing violently as I realize Susie's waiting for me. I rush outside and wave to her just as my phone beeps with another text.
Good girl. Hope you're ready for something bigger than those dainty fingers.
"Is your sunburn back?" Susie asks worriedly and I have to stifle my own laugh as she envelops me in a tight hug, realizing I'm blushing. I fill her in on what's been going on as we walk over to her truck.
"Oh my God," Susie gushes. "So, you and the god of all that is holy and wrong have the house to yourselves?"
I nod, and she smiles with such excitement you'd think she's the one who is about to spend a night alone with Dom.
Susie goes on and on, until we arrive at the beach where the bonfire is burning bright against the backdrop of an inky blue night.
"Well, look who's here," Susie whispers in my ear, and my eyes travel over the mass of people who are enjoying the balmy night. I see a few of the girls I've made friends with and give them a wave, but then my gaze falls on Adrian.
I groan.
I don't want to deal with this right now, because in my mind, I've already made my decision – not that there was much deciding to do. But seeing Adrian makes me feel a little tense and the doubts about my relationship with Dom start sinking in again.
However you look at it, in the end we are stepsiblings.
