I’m sorry little sister, I came inside…
Sex between siblings is already something ugly and immoral enough without him doing what you see in the video, that is, cumming inside his sister without warning. The girl was very horny, but he was much more horny. Seeing her there in bed with that angelic and innocent face only made him imagine her sucking his cock, which the truth is that she achieved without much effort. He just had to plant his cock in front of her face and she started sucking it.
Having oral sex with his sister was fine, but he wanted to see her naked, so he took off all her clothes. Once the girl was naked, he began to penetrate her. He enjoyed putting his cock in her so much that there came a moment when he couldn’t control himself and he came inside almost by surprise. She didn’t notice the river of semen that her brother left inside her pussy, but when she took out his cock she noticed.
His face indicated that he was not too happy with what he had just done, but what’s done….it’s done.
