Cumpliendole el sueño a su hermano III

Tomas couldn't believe he had gone through that again. While his sister went to bathe, he stayed alone in the living room looking at nothing, telling himself he had free rein with his sister when he wanted but also being afraid of overstepping knowing her temperament. Hours passed and he was playing again, Guillermina came down to the living room. She called mom, said they would be back early tomorrow instead of today... Did you hear what I said? If you did, I don't know what you want me to say. Tomas kept playing, Guillermina sighed and went to the kitchen. He cooked something quick for both of them, they sat down and started eating. Each one in their own world, Tomas lost in TV and Guillermina on her cell phone. Tomas turned his head to look at his sister, she was wearing the shirt she uses to sleep without a bra and shorts. He already felt it was going to happen again. With nothing to lose and feeling a bit confident he asked: Guille, do you think we can repeat what happened today? Before mom and dad come back? No... why not? Because I don't want to, Tomas. But if you have nothing to do, I'll do all the work, and then I'll clean up after you. I told you no, you don't understand? And if I wash the dishes? Guillermina already tired of her brother thought of something to entertain him but didn't want to go through his brother's hassle again. I told you no, Tomas, I've already bathed and don't want to get dirty again. If you want, I'll give you a thong or something so you can leave me alone... U... your thong? No, mine... if it's yours, but only so you'll stop bothering me. A thong? Tomas would rather finish it again but since he had already agreed to something, no matter how small, it was a victory for him. Okay! Deal made. When I go to sleep, I'll give it to you, but if you ask for anything else before that, don't fuck with me and leave me alone. Okey okey... but, will you ever let me finish again? What did I say? Do you want to stay with nothing? It's just a question... I don't know... I don't want to talk about it anymore... theme. He got up and went to the living room. His sister's I don't know left Tomás with another sense of victory. From not wanting to do anything to at least giving something, and from not round to not be. Two hours passed and they were both on the couch, Guillermina got up to go to sleep. I'm going to sleep, turn off everything when you leave. Ok. Seriously, are you going to give me the thong? Ugh... yes... I'll leave it in your room. But after you do what you have to do, wash it, and wash it well. I don't want to see a drop of anything or it will all be over here, did you understand? Yes, calm down, I'm not stupid... He went up the stairs and left. Tomás was thinking of staying up late playing but couldn't stop thinking about that thong, so after 15 minutes he turned everything off and went to his room. There it was, on top of his bed, his sister's thong. It was a simple black thong without much detail, seemed like the kind she uses when she's at home, comfortable more than anything. Tomás closed the door, grabbed the thong, and got into bed with his cock in hand. He took the thong to his nose and smelled it. That smell of pussy mixed with soap and flow drove him crazy, his cock got hard. He started jacking off with one hand while holding the thong to his face with the other. He imagined what his sister's pussy must be like, white as her skin with pink lips, completely shaved and delicate like she seems. He also imagined how it would look when it was wet, he couldn't take it anymore, wanting to lick all of her pussy before screwing her. He wasn't going to hold out much longer, when he felt himself about to cum, he put his sister's thong on the tip of his cock, and the cum started coming out and he felt like the thong was getting wet. When he finished, he got up and saw the mess, it wasn't as much cum as when he came in her tits but it was still a lot. He threw the thong off the bed to wash it tomorrow and tried to fall asleep. The next day his parents had arrived. Tomás and Guillermina were in the kitchen... They were counting how they had passed the trip. Their mother was surprised when she saw everything clean. What a clean job! Did you do all this? Yes, well... Tomas was the one who cleaned up everything. What? Tomas? Since when? Guillermina was already getting nervous with these questions and Tomas stayed quiet waiting for his sister to say all the words as always. Ehm, we made a deal. A deal? What deal? The two looked at each other and turned pale. Why did Guillermina say that? If so... The deal was that if I cleaned everything up, I could invite Martin and Julian to spend the whole day, so good, I started cleaning everything jaja... Said Martin, saving the situation. Ah, look, I thought you said no visits... but well, since you cleaned up and they behaved themselves, I'll let them pass. Guillermina sighed and with a glance told her brother well done, it seemed that after all he wasn't as stupid as he seemed. The night arrived and they watched a movie together, an hour later their parents went to sleep and the two of them were left alone. You were good today, I don't know why words wouldn't come out. Yes, it was the first thing that came to mind, do you think she believed it? If so, always believes everything, after all I'm the example. A small smile escaped Tomas's lips between his teeth. What? Nothing. That's funny? Nothing, good, since you're not as exemplary as they say, uh you're a pervert, once you tell me something good you jump with something of masturbation. Well, sorry, but it made me laugh. They kept watching the movie for a while until Tomas noticed his sister's legs, for some reason he liked the color of her skin. That white that attracted so much attention. What can we do, you know... Guillermina looked at him, if her first thought was a resounding no, but after how they had arranged things today she thought about why not? A reward for good behavior? Now? Yes, if they're asleep now... After thinking for a few seconds, she accepted. Well, but quickly... She got down on her knees and did what she always did, until her brother stopped her. In the act But I don't want to finish your tits What? And what do you want then? I don't know, don't you want me to jerk off? No. It's going to be quick, I swear Don't touch, not even drunk, don't ask again because I'll get up and leave. Well, sorry... and if you let me finish your ass? Your ass? Yes, it's almost the same, right? Ay no se, si but no... Come on, it's going to be quick, I promise Guillermina sighed and rolled her eyes. Fine, but quick eh She lowered her pants to her thighs and knelt down in the armchair. Tomas could see all her white buttocks and the white thong passing through the middle. Besides that, he also had his feet right in front of him, he didn't know she liked them until then. Seeing her so devoted to that pose put him at a thousand. He started jerking off quickly, wanting to last but having promised it would be quick and it was better to have his sister content, especially if she lent herself to this. He jerked off strongly with his eyes fixed on his sister's ass. After 5 minutes he started spitting cum, aiming at each buttock. Ready? Tomas said yes as best he could. Guillermina managed to get up until her brother stopped her in the act. Wait! What? Are you going to let me take a picture of it? What? You're crazy man It's for jerking off when I'm hot, so you won't bother me. Guillermina thought about it and understood his point, it was risky but she didn't think her brother would throw everything away over a photo. Okay, just one... Tomas took out his cell phone to take the picture. A close-up of his sister's ass covered in cum. Ready? Yes, thanks. He cleaned up as best he could with some napkins and the two went to sleep.
