Sister took her brother's throat while her beloved man is at work

Here's how well his brother knows his sister and even the fact that she is weak in the head. He knows that it's been a long time since his sister's last sex, so he actively encourages her to fuck him by offering his dick. Sis, of course, broke down for a long time and wanted to wait for her lover from work, but when her brother pulled out his cock, she pounced on it and started sucking to give more in her pussy.
