“Thanks.” I grab a cookie because it seems like I’m supposed to and because she doesn't annoy me immediately. The way she refers to her as Kate makes me think they are close.
Katherine and her friend see me before I even reach the dock, but they just lie there unmoving, watching me. Her friend leans over to her, and I'd love to be a fly on the wall to know what they're saying. When I reach them, I don't even bother to try to hide the fact that I'm taking in the view from above.
“Hey, sis,” I say, punctuating the word for extra affect.
“I told you not to call me that, shithead,” she says, bringing herself up to her hands and knees before flipping over in a huff to sit upright on her ass. I think she's trying to hide her ass from my eyes, which makes me laugh, since the way she's sitting now just gives me a great view of her perky tits. They're barely covered in the white swimsuit, and I can see the darkening of her areolas through the thin fabric. If I'm not careful, I'm going to get a boner standing right here looking at her. I'm fixated on thinking about how to get her back in that hands-and-knees position she was too briefly in.
“I’m trying to be friendly to my new step-sister,” I say, mock sugar-sweet. “Or does it make you uncomfortable to think about the fact that I’m your new brother when you’re fantasizing about me?”
“You’re not my new brother,” she says, yanking her sunglasses off her face and shielding her eyes as she looks up at me. Her nostrils flare at the edges, and I’m amused by the fact that she’s so obviously riled up about this.
“Technically I am, sis,” I say.
“We’re eighteen, asshole,” she says. “We didn’t grow up together. Our parents aren’t even married yet. You and I are not related. We’re nothing.”
I look down at her friend, who’s sitting up now and is watching us, her lips turned up at the edges. She's clearly amused. And, I'm thinking as I look at her, certainly no eyesore herself. “She’s just touchy because she got a look at my cock and now she can’t stop thinking about it.”
“Oh?” her friend asks, glancing at Katherine. Kate's face darkens. “You didn’t tell me this.”
My new step-sister looks at me, her eyes wide. “Don’t listen to anything he says. Caulter is full of shit.”
Her friend’s head swivels toward me again, and I glance at her impressive rack, thinking that maybe Katherine's friend is exactly what I need to get Katherine out of my head. “Full of shit?” she asks.
“I’m full of shit, am I, Katherine?” I ask. “So you've never seen my dick?”
“Shut the hell up, Caulter,” she says, standing, her face level with mine. My cock stirs as she glares at me, the flash in her eyes a warning. She thinks I’m about to tell her little friend about our night together; the fact that she’s so obviously upset makes me simultaneously irritated and pleased.
I turn toward Katherine’s friend, who is splayed out casually on the ground, watching us with amusement. “She has, in fact, seen my cock,” I say. “And apparently, she can’t take her mind off it.”
“Come on, Jo,” Katherine says, huffing. “He’s a moron. Let’s get out of here.”
“She didn’t tell you about our little bathroom incident, did she?” I asked. “How I walked in on her changing?” Katherine's expression changes when she understands I'm not about to reveal what happened between us that night.
“No, she didn’t tell me,” her friend says.
Katherine rolls her eyes. “He has no boundaries,” she says. “He thought it was perfectly appropriate behavior to come in while I was in the bathroom and proceed to take a leak in front of me.”
Jo snorts. “That's rude, yes. Completely.”
“I did not take a leak in front of her,” I say, ignoring Katherine. “But if I had to wait for her to stop talking, I’d have pissed myself waiting.”
Beside me, Katherine makes a sound of frustration. “He’s completely full of shit. Jo, are you ready?”
“Jo,” I say, offering her my hand. Jo rises to her feet, her full tits bouncing as she stands. I can’t help but look. “It’s so nice to meet you. Any friend of Katherine’s is a friend of mi -”
“Oh no, I don’t think so,” Katherine says, reaching around me to grab Jo’s arm as Jo laughs. “She’s not a friend of yours in the least. I’m not a friend of yours. You and I are not friends. Don’t even try to hit on her.”
I put my hand over my heart. "Katherine, your words cut me deep."
Jo shakes her head. “I don’t know, Kate, you guys definitely seem to fight like brother and sister.” She walks forward, leaving Katherine and I standing at the end of the dock.
Katherine is facing me, and I lean in close, my mouth near her ear, wrapping my hand around her wrist. “Don’t lie. You can’t stop thinking about my cock. Tell her how much you moaned when I was inside --”
“You’re a pig,” she whispers. I can see her jaw clench.
“If I'm a pig, maybe Jo needs a little pork, then, huh?” I whisper. Jo's several feet ahead, too far away to hear.
"Don't even --" Katherine starts. She wrenches her arm from my hand and before I realize what she's doing, her hand is on my chest, pushing me off balance.
