Boyfriend?

We were walking while holding hands like a couple. Not like most brothers and sisters who fight all the time.

"Look, there is a lingerie shop. Let's go." Sis stopped when she noticed the lingerie shop.

We entered the shop. Well, it was my first time ever entering such a shop. I felt that I entered a completely different world.

She looked at me and announced "Okay, choose only two sets. I will try them now. If I like it I will buy more next time."

"Leave it to me, sis," I replied confidently. "You will like them for sure."

"Sure, lil bro." She chuckled

"How may I help you, mam?" The shop staff came to us and asked.

Sis looked at me and replied, "My boyfriend will choose for me."

I was surprised by her exclamation. She looked at my eyes and I understood that it would be weird if I, a brother chose sexy lingerie for his sister.

That staff member looked at me and smiled and said "Sure, sir can tell me his preference I will get them for you."

I nodded and acted like I really was her boyfriend and said "Can you show us the latest design?"

The staff nodded and took us to the side where the latest design wears were. I could feel a little shyness from my sister's face. She was trying hard to not show them.

I almost laughed but stopped myself. I didn't want to die when I reached home. After all, I just got a System and didn't have the time to shine, yet.

I looked through all and finally selected two sets. The first one was a pink set with a rose print bra and the same print thong. The Second was a black set with a beautiful design and G-String panty.

Di pinched my arm and her face was red but she didn't say anything. She just gave a dark smile. I knew that she would lock my neck again. But I was willing to take the pain.

"Wow, Mam! Your boyfriend has a really good test. I wish my boyfriend was like him." She sighed and commented.

"Yes, my 'boyfriend' is naughty." She replied and continued to look at me with her previous smile.

"Haha, sometimes being naughty is a given when one has such a beautiful girlfriend as you." The staff smiled and praised Di.

Di gave a normal smile and nodded. We then quickly paid and took the package and left the shop.

As soon as we came out Di pinched me again and "You really selected those. I would never wear them outside."

"Ouch! I thought you would like them." I screamed in pain.

"Well, they are good and look sexy. But…." She blushed.

"You can wear them at home. If you don't like them then next time we can buy a different type." I added while rubbing where she pinched.

"Why would I wear them when I can be without them underneath?" She replied

"Don't tell me you don't wear any inners at home," I replied, rolling my eyes.

"I only wear a bra at home." She replied casually.

I looked at her with surprise. I remember last night how we were lying on the sofa. Di also seems to remember that so she added "It's only you at home, and I like to feel comfortable at home."

I shook my head and stopped myself from getting those weird thoughts again.

We decided to end our shop and return home. On our way back, Di drove and I sat behind her.

Di bought some groceries for the house on our way. As soon as we reached home I went inside her room with the bags and she went to the kitchen to put the vegetables in the fridge.

I hopped on her bed and took out my phone. I saw a few notifications from Mom. I didn't reply to her immediately. I waited until I went to my room.

Di also returned after she kept the bag in the fridge. She then started to take out all the clothes. She was satisfied with them.

She went to the bathroom and changed into each of them and showed it to me. She looked beautiful in them.

Lastly, she took out the lingerie. She looked at the G-string and asked "What will this cover? Aren't you asking too much for your 'accident'?"

I felt embarrassed and replied "You don't have to if you don't like it. It's not like you bought them to show me."

"When did I say that I don't like them? And they are expensive, it would be a waste to not wear them." She replied after giving me a stinky look.

"As for showing you, what difference it would make if you see me in them. You are my brother. Last night I saw you completely naked." She replied while laughing.

"I am a man too, you know," I replied speechlessly.

"Oh, I have seen how manly you are yesterday. But you are my brother first." She chuckled.

I looked at her weirdly. She was too similar to Mom. They both acted the same way. I again remembered that mom had a picture of my dick in her phone and felt my face was burning.

"Then why don't you change into it and show me now." I scoffed

She only smiled and went out again. I was shocked 'Is she really going to do this?' I was surprised but also excited.
