Brenda

I'm not a fan of shopping, but I've liked her a lot so far. When I said her name, she blushed and giggled. Katia raised her eyebrows and smirked.

"That means Sarah will be my exercise buddy. Sweet. Get ready to work out for hours."

Sarah just laughed and blushed.

"Oh, stop it! I mean, I could work out with you, yes. You think it's a good idea, Liam?"

"Physical activity is never a bad idea. Although Katia does seem to follow a... Hard regime."

"Oh, it is hard, really hard." She chuckled and nodded.

We finished eating and I got ready with a shower. After I got dressed, I saw Sarah and Katia had gotten changed as well. They were now wearing sports bras and shorts, although Sarah's seemed much tighter than Katia's, emphasizing her huge breasts and her amazing ass. Katia looked incredible too, as her body as in peak condition.

"We'll go for a run, then we'll continue here. You mind if we move the furniture a little, Liam?"

"No, that's cool. As long as you don't break anything" I reply to Katia.

"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 Brenda!"

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

"She'll be more than fine!"

I opened the door for Brenda, and we all waved each other good bye. I wondered why Katia had gotten changed instead of wearing her sportswear from the beginning of the day, but that was such a small thought I immediately forgot about it.

Brenda was quiet for most of the ride to the mall. It was nice, as I drove without any worry, and she seemed comfortable with the silence.

"Thank you for choosing me" she finally said when we were approaching the mall.

"Don't mention it. You're twins, but Katia is very different from you. No offense."

She giggled.

"None taken. I am aware of it, yes. We... Developed differently. The jokes about the twins from The Shining stopped when we were around twelve. It seems I got more of... Sarah's side of the family." She gestures downward, at her large breasts. "Katia decided to work out her body instead, so we grew basically opposite ways. She's stronger and I'm... Uh... Rounder."

"You look fine."

"You think so?" Was she blushing?

"Yeah, of course. Also, I actually meant your personalities."

"Ooh, right! Yeah, that too." She giggled once again. She was adorable. "We have... Different outlooks on life, I guess. Who... Do you prefer?"

"To be honest, you're nicer." That was a weird question, but an easy one.

She blushed harder than ever and smiled wider than ever.

"I really appreciate it, Liam. Katia isn't bad, she's just... I know she can be a bit... Aggressive. But she's protective, and thoughtful of those she cares about. And she has a huge... Uhm... Heart. She has a huge heart. You'll see it soon."

"I trust you and Sarah. It's just... She's a bit too smug."

"Yeah! She... I think she needs to. She's the firm one. I'm the soft one."

I parked the car and we walked inside the mall.

"I promise I won't take long!" Brenda said excitedly. I just nodded.

I was thinking about Sarah. She occasionally went for a run, but if Katia was right about the intensity of her exercise, then I was a little worried about my girlfriend.

"Come this way!" Brenda said while grabbing my hand. It was a casual grab, a very friendly one, and the tug she gave my hand was gentle. But she quickly let me go. "Oh, sorry! I didn't mean to... I... Uh... Are you okay?"

She was trying to hide the fact she had blushed really hard, but I decided to fall for it.

"Yes. I was just... Concerned about Sarah. What if Katia makes her work too hard? Sarah is in amazing form, but she's not as... Athletic as Katia. And she said they'll work out for hours?"

"Katia's just like that. They won't be doing it for literal hours, she always lets us breathe."

"Oh, so you also do it with her?"

She goes silent for a moment, then giggles.

"Occasionally. Often. Quite often. Oh, but I eat more than I should, so I'm still chubby..."

"You're kidding? I can barely call you chubby! Not that there's anything wrong with it. You look amazing, honestly."

"Thank you, Liam."

She blushed even harder. It was not my intention, though. Brenda gave off an aura of sweetness and kindness, I couldn't help but being sweet and kind myself.

"Let's go shopping, then!" I invited.
