My sister...

I went upstairs to find my mom completely shocked by something, she dropped the bags with clothes as she was staring inside Annie's room, i got closer to take a look, i sticked my head to see something really disturbing.

In her bed there was random naked dude on top of my fully nude sister, they were clearly having sex but when mom openend the door they both turned around with a surprised face. They were caught doing a naughty think and from the expressions of their faces i could tell that they knew they fucked up and they fucked too... yes but what i mean is that mom was probably going to freak out at this sight

Annie covered herself and the dude on top off her stood up and tried explaining the situation while getting closer to mom. "W-we can explain... w-we were..." he kept stuttering but mom interruped him "No, you both, come down to the living room NOW!"

"But mom! We..." Annie tried to argue but mom gave her a strict stare, which meant that she was serious and Annie didn't have a choice, she got up from the bed, didn't even put on clothes and followed mom that was going downstairs, the random guy also followed her like he was her son or something, he was going to obey at everything that mom said.

The naked couple went right passed me, i don't think they even noticed me there. Annie stared at me for half a second, she wasn't even mad at the fact that i was staring at her naked body as she made her way to the living room. I picked the bags with clothes and threw them on my bed, then i quickly went downstairs to watch the argument that was about to unfold.

As i was running down the stairs i heard my sister scream "Is none of your business... you can't tell me what to do!" I finally got there and saw mom sitting in the couch, she was calm and collected while she had a discussion with my naked sister and her naked sex partner. I kinda just stood there watching until mom noticed me hearing the whole discussion, she made a gesture to come over to her and so i did...

I took a sit with her in the couch, she wrapped her arm around me and hold me so i could rest my head on her shoulder, she gave me a few pats on the chest like i was some sort of child scared for life and she was trying to calm me down.

Annie looked at me and exclaimed "What is HE doing here?!" Mom stopped patting my chest but kept holding me and replied "You caused some trauma to him with what you did so he is going to be with me to hear what you have to say... now what do you have to say for yourself, give me an explanation and don't give me excuses"

Annie sighed and looked at the guy next to her, he was shaking in fear, my sister hit his shoulders and made a gesture with her head like he had to say something. He then prepared to speak, he cleared his throat and looked at my mom directly in the eyes and said

"Hello Mrs. Price... nice to meet you, i'm David, Ann's new boyfriend... we were just having some fun in the bed, we didn't know you arrived so i'm deeply sorry if this offended you or something" Mom looked at him, inspecting her entire body with her eyes, she specially focused on her flaccid penis before looking at his eyes again and saying

"Well that's okay, i didn't know you too were a couple... i understand that you like to do this kind of things, you are young and in love so i think is healthy that you take time to show your love and affection" everyone was surpised by her answer. Annie's jaw dropped to the floor and her boyfriend looked around like he wasn't sure if this was real or not. Even i looked at her, she looked at me and gave me smile like she was saying Everything is fine, honey... remember that i'm totally cool with sex and i actually love seeing that you and your sister get in relationships and that you are sexually active.

I know that last part she probably never would say but that was the impression that she gave me when she said that she was cool with seeing my sister naked and having sex with her boyfriend in such a relaxed tone.

Annie broke her state of shock and said "So you are cool with it?" Mom replied nodding and saying "I mean, as long as you keep yourself safe i don't find any problems..." Annie looked like she was planning more meetings with her boyfriend to have sex in her room but mom continued saying "However, i would appreciate if you gave me a call, text or anything to let me know that you are bringing boys home" Annie nodded rapidly and said "Yes, anytime... i will always text to let you know"

Mom smiled at her and said "Then we are fine... although i will ask you David to please leave, is really late so i think you should go home" David complied and went running upstairs to get his stuff. Mom turned her attention to Annie and said to her with a hand in her shoulder "I expect you to not give us any more of these surprises Ann, you know i'm fine with that but think about youe little brother" they both looked at me and she proceeded saying "Look at him, poor thing, he doesn't deserve to experience these types of things... so next time lock your door and be more careful ok honey?" Annie looked at her and nodded like she was a small girl listening to her mom. It surprised me to see her like that because she never listened to mom, she almost never obeyed her orders and even insulted her a couple of times. Mom kissed her head and went to her room, she turned around before entering her room and said "Go get dressed and go to sleep, i'm also going to sleep... it's been a long day" and with that she closed her bedroom door, leaving me alone with my fully naked sister, i was still confused from all the things that happened, i found myself blankly staring at Annie's body.

"What are you looking at? I guess you enjoyed this argument, you got to see your sister's sexy naked body huh?" I didn't reply, i kept staring at her but now i was actually focusing on her body.

Damn, she is so sexy... i thought while looking at her body - i always knew that she was pretty, i had seen her naked before but only now i realized how beautiful she was. She was around my height, 5'10, she had a nice petite body with great titties, i don't know what size they were but i was guessing that it was around a C and a D cup. She had long light brown hair that reached her shoulders, she was a lighter tone of skin than mine, her eyes were grey and her general face structure was flawless, there was nothing to criticize, she was just a really hot sister with a nice well rounded ass.

"Umm hello? Fucking perv..." she said before going upstairs and saying goodbye to David, she kissed him on the lips and i saw from downstairs how he grabbed her pussy with a full hand before she pushed him off playfully, David reached the entrance to leave the house but said to me "Take care of your sister, i will be coming back and i hope she is ready for me so make sure she feels happy while i'm not here" he winked at me and left the house. What the fuck does he mean by that? I asked myself. I went upstairs and saw Annie putting on her clothes, she was only wearing a large shirt with nothing else, no bra, no panties... nothing, it was weird but i wasn't going to stop to mention it.

I finally got in my room and started hanging all of my clothes in the closet, it was now full of cool shirts and hoodies that i couldn't wait to use.
