Cumpliendole el sueño a su hermano IV

Tomas already felt more confident with his sister, too much confidence... The day began normally, each one preparing for their day. Tomas to go to school, Guillermina to the university and their parents to work. Tomas couldn't stop thinking about his sister, he had become addicted to finishing her off. He had decided that when he got home, he would ask his sister if they could do something, whoever was at home. And so it was, he arrived home and saw Guillermina sitting at the table with papers on the table, she looked more stressed than normal. Good evening Are you busy? Yes, don't you see I'm studying? The coldness of his sister scared him a bit, but he kept going with what he had planned. Eh... do you think we can do something later? No, Tomas, I have to study, don't bother me, please. But then she didn't even let him finish talking. With such a clear response like that, Tomás gave up and realized it was better not to bother her. The hours passed, everyone had dinner and she went to her room to keep studying. Tomas went to his room with the idea of wanking off watching porn, but it wasn't doing anything for him, he needed his sister. So he got up and without more went to his room. He entered and sat on his sister's bed while she was at her desk. Quiet, I'm not going to bother you. And then what are you coming for? Seriously, I need to study. I wanted to ask forgiveness for today, I crossed the line. Guillermina was surprised to hear that. She knew that the fault of all this was hers for agreeing to do it, but she wasn't going to let her brother hear it. It's okay, don't bother me when I'm busy. Or so can we do things when you're not busy?... We'll see. After hearing this, his cock got hard, he needed to wank off already. He stayed silent for a few seconds until he couldn't take it anymore. Sorry but... can we do something now? I know you told me not to bother you, but seriously I'm very... Hot. Are you jacking off? I told you I have to study. Grab a thong and jerk off in your room. You've got a photo use that. And if I jerk off while you're studying? Don't get me wrong more tits. Nobody said anything about getting down on my knees stupid. And if you sleep with me and jerk off with your ass? That way you'll be able to keep studying, I won't open my mouth, I swear. Guillermina thought for a few seconds and agreed. Well, but this time and ready by the week. I'm going to let you finish me off again, but don't talk to me until Friday when I'm done, okay? Ugh... well... Guillermina got up from her chair, took off her short and left on thong to fall asleep in bed with the papers on the pillow. Tomas did his thing, took off his boxer and put himself on top of his sister. He started jerking off with his eyes fixed on that white ass, stayed like that for a few minutes. Can I touch it? No But this way I'll come faster! Oh God, do what you want but don't go over the line, seriously I'm telling you. Her eyes lit up. While he was jerking off with one hand, with the other he started caressing his sister's ass very delicately. He was trying not to get too close to her pussy, didn't want to make her angry. Five minutes passed and he already wanted to paint her ass with cum, so he increased the speed of his masturbation and the delicate touches became more aggressive. He grabbed her ass with force, had a lot of desire to rip off the thong and screw her there right away, but knew he couldn't. He couldn't take it anymore, felt the tingling sensation. The cum started coming out and tried to throw it on his sister's two breasts. Seeing how the cum was sticking to her ass drove him crazy. When he finished jerking off, he gave himself a few slaps on the ass and stayed looking at it for a few seconds. Are you done? Half an hour more before I get pegged with cock in the ass... Sorry... They stayed silent for a few seconds. And? What are you waiting to get up. P sorry. Do you want me to clean up? No, leave... let me study please. And remember what I told you, don't I want you to bother me all week, seriously I'm telling you. Tomás got up, put on his pants and went to his room. He didn't remember the last time he fell asleep so happy. The week passed more slowly than normal, he couldn't stand seeing his sister and not being able to jerk off on top of her. Guillermina noticed it and sometimes let me wear some thongs but nothing else. Tomás had many times been close to asking if they could do something but held back, knowing that if he fulfilled the treat he would let him do more things. Friday arrived and Guillermina finally took her exam and was free for now. She was getting ready to go out. Tomás passed by her door and saw she was putting on makeup. Want to go? We're going to grab something with the girls, maybe we'll hit the club later, depends on my mood. And what time are you coming back? No idea, why? Nothing, ask me. I had a black leather top that showed almost all her tits and a black high-heeled shoe, she knew what she had and liked to show it off. Can I jerk off before you leave? Are you crazy? I'm already changed. I didn't want to ruin any chance I had left so I didn't insist. You're right, don't want to ruin the outfit jaja. Well, have fun. She got up and went out to play as always. Hours passed and it was late, I heard the door and it was her sister coming back from going out with some other drinks. Are you still playing at this hour? Yeah, what else am I going to do on a Friday night? I don't know, socialize? She said while serving herself a glass of water. Her brother couldn't stop looking at that neckline she had and she was aware of it, felt a little uncomfortable. Could you tone it down a bit... If you wear that, it's not for people to look at you like that? Yes, but not for them to look at me with a degenerate face like yours. Well, sorry, I can't help it. She finished her glass of water and stood there looking at her phone for a while. Tomás didn't lose the opportunity and seeing his sister was a little drunk took advantage of it. Are you going to sleep now? Yes, no

See what time it is? You should also go to sleep. If you're already sleepy, can I cum before sleeping? That's how direct, right? If so, it's because I have a lot of desire and seeing what you're wearing doesn't help much... Guillermina looked at herself and gave me the reason. Well... but quickly because I'm tired Tomás was surprised by how easily he got in and quickly followed her to her room. Guillermina didn't say a word, just knelt down while still holding her phone. That's it? He said Tomás And what else do you want me to do? Nothing, that's fine. She took off the boxer and started wanking looking at that cleavage of her sister. Thought about taking advantage of my luck and crossing the line a little again. Do you know I'm going to stain your clothes? Guillermina looked at herself and thought for a moment. Yes... but I don't feel like changing. And if you take off the top? Not even in hell Tomás, I don't have a bra on. And? How about it? No way am I going to see you naked. But it's so you won't get stained, and I'll finish faster anyway. They stayed silent for a few seconds before she finally agreed. I'm going to take this off, but it will be the only time okay? And don't want a but or anything... If you're calm... She took off her top and finally those white tits came out into the light. They were almost perfect, round, firm, with pink nipples. They were just like I imagined Tomás. My cock got hard and I started wanking right away. I couldn't take my eyes off those beautiful tits. Can you hold them together with your arms? What? Hold your arms up Guillermina did what he asked, held her arms up and the tits pressed against each other. Tomás imagined putting his cock in between and cumming on the tits. I can't hold out much longer and the cum started coming out. Tried to give it to both tits, one after another. When I finished, saw how the cum was falling, some even reaching almost to the neck. How do you manage to cum so much... that's disgusting. P... excuse me, it's just that your tits are perfect. He said with barely any breath left Gracias? Pass me that towel Tomás didn't say a word, passed her the towel and put on his... boxer Thanks, I'm going to sleep Said with an enormous smile while closing the door. Goodnight 😁, excuse me for the delay, I don't have much time to write and that's why this part isn't as long as the others, but I wanted to leave you something so you know I'm still alive jaja. The next part will be more detailed and hotter, Tomás is better than ever.
