Olga ⇐ Sex between blood relatives

[Story]

This is just a story, a fiction.
Oleg, 13 years old, and his sister Olga, 14, were vacationing in the village with their grandmother. It was great. Forest, river, fruits, berries. And even Olga, who had a complex in the city because of her plumpness, wore light, short dresses here without any problems.
A week passed and Uncle Kolya came to rest. Older brother of Oleg and Olga's father. At 42, he looked great. Well-groomed, sporty, cheerful. Oleg noticed that Uncle Kolya was paying increased attention to Olga. He invites you to go pick up strawberries and go on a boat ride. When he was repairing the roof of the bathhouse, he stood on the stairs and asked not Oleg, but Olga, to give him a tool. It was hot and Uncle Kolya was in shorts. While working, he stepped from one step to another and his underpants rode up, exposing his penis with a large dark pink head. Olga was ashamed of what she saw, but even turning away, she crossed her eyes. Having finished his work, Uncle Kolya falsely exclaimed; Oh sorry. I didn't notice it. Why didn't you tell me? Olga was silent, lowering her eyes. But both Oleg and Uncle Kolya noticed the blush on her cheeks. Uncle Kolya, hugging Olga and stroking her lower back, asked: Have you seen this before? Olga remained silent. Uncle Kolya, not paying attention to Oleg, leaned towards Olga’s ear and whispered: You are very beautiful. You have a great ass. Tonight go to bed on the veranda. I will come to you.
When the house was quiet, Oleg climbed out the window and in the dark crept unnoticed into the bushes near the veranda. While hiding, he heard Olga tossing and turning on the sofa. Soon Uncle Kolya quietly passed by. Even though the conversation on the veranda was muffled, Oleg heard everything well. Mainly the voice of Uncle Kolya; Move over, I'll lie down next to you. You are afraid? ; A little. ; Everything will be fine. You will remain a girl. This can be done in the ass. Trust me. Just lie on your stomach. I'll do everything myself. Oleg heard a commotion on the veranda. And again Uncle Kolya’s voice; Like this. Everything is fine. Relax. Rustle sounds and a sharp cry from Olga. Olga's muffled moans. Curiosity won and Oleg stood up and took a couple of steps towards the veranda. In the light of the moon I could see Olga lying on the sofa on her stomach. Uncle Kolya is on top of Olga, with his left hand he covered Olga’s mouth and with his right hand he hugged her so that he pressed her arms to her body. She couldn't break free. Uncle Kolya slowly moved his pelvis, thrusting the entire length of his rather small penis into Olga’s anus. Oleg watched as if spellbound as his sister was fucked in the ass. He didn't care whether it hurt her or not. One thought was spinning in my head: Olga’s ass was torn. Oleg's penis throbbed in his shorts. Later, Oleg wondered how it happened that Uncle Kolya and he came at the same time.
That night Oleg and Olga learned a lot of interesting things. They came to the village to visit their grandmother more than once. And their mother also likes to relax here. But those are different stories.
