Katia

I'm not a sporty guy, but I wasn't gonna let her get away with it: she'd have to train with me. When I said her name, she laughed out loud.

"Really, dude? No offense, but you won't be able to keep up with me. Not even five minutes.

"Come on, Katia, don't be like that!" Brenda said, slapping her sister's shoulder playfully.

"I said «No offense»! Look, you're kinda scrawny, Liam, let's face it. Nothing wrong with that, just... You will just faint, probably."

"Oh, yeah? We'll see." I challenged with a smirk of my own, which Katia seemed to like a lot.

"If you're sure, then let's go, dude."

"Take it easy on him, Katia." Sarah asked her, although she didn't sound so convinced.

We got changed. I put on some shorts and a sports T-shirt. Katia was wearing really short shorts and a sports bra. Honestly, she looked incredible. Her body was truly in peak condition. I started to doubt if I'd be able to keep her rhythm.

"We'll go for a run, then we'll continue here. You don't mind if we move the furniture a little, do you?"

"No, that's cool. As long as we don't break anything" I replied.

"See you later, Liam!" Sarah hugged me and kissed me. She seemed so happy we got to share time with her cousins. I felt it was her attempt to include me in her family, and I felt amazing. "Take care of Katia!"

"Don't worry, we'll be fine. And you take care of Sarah!" I told Brenda.

"We'll have fun!" She said happily.

Sarah took my car and left.

"Alright, dude. I saw a park nearby when we were coming yesterday. We're going there." She wasn't asking, she was ordering. She didn't even wait for my answer, she just went for the door, expecting me to follow her, which I did.

It was a nice day to be outside. I wondered how long it had been since I last worked out, and if I'd survive.

"I thought you'd go with my sis" she said as we walked to the park. "She likes you a lot."

"Well, maybe that was the reason. I don't need to work on that. On the other hand, you don't seem to like me much, so we can improve."

She laughed.

"I don't hate you. But I like messing with people. Brenda is such a cinnamon roll. That's kinda cute, but not my thing. You know? People used to make a lot of jokes about us. Both when we were identical, and when we started to look different. Folk are never happy. So I decided I'd kick their butts if they kept on messing with me, my sister, or my cousin. And that has worked wonders."

We got to the park. There were some people jogging and walking by there already. Many stared at Katia's incredible shape.

"Yeah..." I said. "You two don't look like twins at first glance. Your faces are definitely the same, but your bodies..."

"Have a problem with our bodies?" Katia raised an eyebrow and folded her arms, making her biceps and her breasts pop out a little.

"No, absolutely not! You are... Completely amazing! And Brenda is beautiful as well!"

Katia raised both eyebrows, then laughed.

"Oh, yeah, she is. She's got a little cute belly, and killer hips, and huge knockers. And Sarah is also so hot."

It was weird how freely she was able to talk about her own family, but I just shrugged it off.

"Don't you think, Liam?"

"What?"

"Do you like my sister's jugs?"

"I... I think I shouldn't say that."

Katia laughed out loud and passed an arm around my shoulder, pulling me towards her. It was like being crushed by cushioned concrete pillars. I imagined that, if I ran into her, I'd definitely break a bone.

"Come on, dude! We're family already, you and me! You can tell me, respectfully, if you like what my own sister looks like!"

"Uhm..."

"Come on, say it! You like her huge boobs?"

"They're... They're pretty, yeah. They're big and... And squeezable?"

"There you go! Was that hard? Now, I know you aren't gonna cheat on our Sarah" «Our?» I thought as she spoke. "But you can be honest with me! I might be a bit of a jerk, but I'm blunt! For example:"

She pointed at a woman jogging nearby. It was a brunette with tight leggins and top, with amazing curves.

"That girl over there, isn't she pretty? Wouldn't you like to eat those titties?"

"Uh..."

"That's the kinda honesty that's good for you, dude! Come on, let's run!"

She slapped my back, almost breaking one or two or my vertebrae, and stared jogging.
