Her Stepbrother Would Confess Anything in a Threesome

My best friend is so pretty and hot, but her stepbrother keeps teasing her, saying she's unfuckable. I know he's only saying that because he wants to sleep with her. I tried to explain that to her, but she wouldn't believe me, so I had to prove it. I went inside her stepbrother's room and rubbed his cock. When he was on his bed, waiting for my next move with his dick hard, I made his stepsister walk in and asked her to suck it. He said that was way too much, so I covered his eyes with the panties she was wearing, let her give him a blowjob, and made him guess which one of us did it.
He enjoyed it so much that he didn't care anymore, he wanted to fuck both of us, and we were desperate for that too. We took turns playing with his cock and riding it. When I let both of them lick my tits, I finally made him confess everything. He admitted that he was mean to her because he had been wanting to fuck her for so long. Now, all that was left to do was let him pound her wet, tight pussy so he can be nice. Mine is ready for him, too.
