My best friend's sister

It starts when my best friend Marcos invites me and our common friend Daniel to go play and sleep over at his place. The day begins normally; I arrive in the afternoon around 6 pm, greeting his mother and sister Camila, a 19-year-old girl, 1.55 meters tall, weighing about 40 kg, with a beautiful body and a lovely face. As night falls, we three go to buy some beers and snacks to eat while playing, around 11 pm Camila enters Marcos' room to sit with us, talk, and drink something. By 1 am I was getting a bit bored of playing, so I took my phone, sat on a couch next to Camila, and started checking my messages. Camila then says will you come with me to get water, it's very dark and soon Marcos turns around with a serious gesture; I respond to Camila that yes, I was also thirsty. On the way to the kitchen, she grabs my arm at the elbow height, which seemed a bit weird since we had barely talked before. When we arrived in the kitchen, while she served her water in a glass, I told her to serve me one too; I went to the bathroom and when I returned, she was still taking her water and started telling me she was bored and didn't want to sleep. I told her to stay in the room drinking beer with me since I was also getting bored of playing. Returning to the room, she took my arm again and said you're scared of the darkness and I responded that yes; at that moment I thought it wouldn't be a bad idea if she didn't leave and I took her from the waist almost touching her butt and placed her in front of me. When we entered the room, Marcos and Daniel were still playing. I sat on the couch with Camila drinking beer and checking my phone; then she put her hand over my pelvis and I found myself sitting next to a beautiful girl who was touching me near my cock; soon I got an erection, which for me was bad luck or not so bad haha. erection ended up coming out towards the top where she had her hand resting, the tip of my cock lifts her hand and she immediately takes it away, I looked at her eyes, made a gesture 🤷🏻 She didn't give it any thought and put her hand right back there, minutes later started moving her fingers up and down touching my glans, I took my arm and put it behind her, caressing her buttocks, she had on a soft pajama short that showed off incredible buttocks, and an oversized shirt that reached to the middle of her butt. I lifted her shirt and began to caress her skin above the short, she kept touching me and put her hand in my pants, touching my cock through my boxer briefs which were wet from precum, she asked why I was wet, I replied it's normal when men get excited, she continued touching my penis up and down. At one point Marco turned to take a beer and saw us together but we pretended not to see his phone, he looked back at the screen to keep playing. By 2:30 am there was no more beer in the room so I said I'd go look for some left in the freezer, Camila came with me again, after all that fondling I grabbed her breasts and kissed her, she responded by putting her hand on my cock from the tip to the balls, that lasted a couple of minutes and we went to get the beers. I gave her a breast suck while getting the beers out of the freezer, and fingered her vagina, it was all wet. When we got back to the room Marco and Daniel were turning off everything saying they had to sleep. I said I'd stay in the living room finishing the beers with Camila, they didn't give much importance and we left the room. Already in the living room we put the beers on the table and stayed drinking while waiting for them to fall asleep. After 20 minutes I checked and they were already sleeping. When I got back to the sofa Camila gets down on her knees and pulls down my pantaloneta to give me a blow job, starts sucking gently at the tip making circles with her tongue. I felt like drops of pre-seminal liquid were coming out and she kept sucking until a moment when she tried to take in all of my cock but only got halfway, I have an 18cm cock. She didn't get past halfway, she kept making circular motions with her tongue and eating what she could. I tell her to slow down because now it's my turn to give her pleasure, I lower the short and it was all wet, I start licking from top to bottom quickly, after a few minutes she asks me to put my cock in, I try but it was very tight so I started putting in fingers, then two and tried to put in the third finger but it wouldn't go in because she was squeezing too hard and didn't want her to feel too much pain, I just kept licking and putting in my fingers, after about 10 minutes I went back to trying to put my cock in, it went in but she was squeezing too hard, she grabbed my arms tightly while I covered her mouth so no one would wake up, I put her short in her mouth to avoid loud noises, then after a few seconds I started moving slowly to get her used to my penis, she just squeezed my arms with great force, I kissed and licked her breasts, after a while I felt like a lot of liquid was coming out of her vagina, she had come. At that moment I start making faster movements until the end, she just bit her short and squeezed my arms. After a while of me giving it to her, she asks to be on top, she dedicates herself to riding me, already I felt like I was about to come soon and I tell her to get off and start sucking me, put my penis in her mouth and with the minutes left, I release my load into her mouth and swallow. I still had more desire, she cleans my cock, rinses it without leaving a single drop of semen, puts me on all fours on the sofa and starts taking my cock until the end without stopping. She was already running minutes later and let out a moan that could wake someone up, we were still scared, I put her in missionary position and came on her abdomen again. She continued sucking my cock for a good while, it was 3:40 am when we heard someone open the door to Marcos' room, Camila quickly went to her room naked, I pretended to be asleep on the sofa. Daniel woke me up telling me if he had heard any noises, he started telling me that he thought he had heard Marcos' parents having sex, and that he had heard moans. I told him to go back to sleep. Later, Daniel returned to the room, I went to the bathroom to clean myself off after all those fluids, someone knocked on the bathroom door and said 'I'm Camila', I opened it, I still had an erection, she got down and started sucking me in the bathroom. She told me she wanted to try using her other hole, I told her it was probably going to hurt more than when I penetrate her vagina, she took out a body oil from a shelf, applied some to her anus and started making movements to dilate it, after 2 minutes, I had already put enough oil on her anus and my cock, I tried to get in but it was very tight, I kept trying with my fingers and managed to get half of the glans in, slowly pushing until I got my whole head in. I started making gentle movements for her anus to get used to it, after a while, I started moving about 6 cm deep, I started going in and out, leaving her anus dilated for me to enter and exit, she told me it didn't hurt and that she was enjoying it more. After a few minutes like this with her tight ass, it was inevitable for me to come inside, despite having ejaculated twice, I left her anus full. It was 4:30 am when she told us to hurry up and take a shower because her mother gets up early, I got out of the bathroom in a towel first and her mother said... leaving her room and she looks at my arms, red and scratched, she says what's going on with your arms, I'm a bit scared looking at my arms I tell her I've been like that for a while already. She doesn't give it much importance tells me to go to sleep and heads towards the bathroom. I call out to ask her something as she was walking away from the bathroom Camila comes out and hides in the laundry room, when her mother enters the bathroom she goes back to her room and I follow her, we end up lying down on her bed, she kept touching my cock which had gone erect again, she only caressed it, a little later I heard her mother enter her room, at that moment Camila was already asleep, I get up and go to Marcos' room where they were still sleeping. I sleep until 10am, have breakfast with Marcos, Daniel, and Camila. While we're at the table Camila lifts her feet and puts them on my bag, looking at me from across the table, Marcos and Daniel didn't notice, they were talking about a game. A little later I'm getting ready to leave, I say goodbye to Marcos' mother and give Camila a kiss on the cheek. As I'm heading towards the door to leave, I hear Marcos' mother say and that kiss, you've never said goodbye like that before. Already in my mind I thought if only she knew I had blown all her daughter's holes. To be continued.
