24F caught sucking my friends brothers cock

So we were at my friends house, the one in the sleepover story. I was in her brother's room right beside the wall, and I was giving him a blowjob before taking a shower. And just when I took his dick in my mouth, the door opened and it was her.

She just awkwardly said, "Keep it in mouth, I don't want to see it" and left. I continued to blow him as I didn't want to ruin the moment. But he definitely got in mood after his sister saw me sucking his dick. Maybe he had some fantasy of fucking sister's best friend lol. Or her lol

When he was about he to cum, he grabbed my head and fucked my face. He came in my throat and I went to take a shower.

I talked to her after taking a shower and she's okay with it. She just told me to lock the door next time and also warn me to stay away from kitchen, she knows her brother loves kitchen sex, I don't know how she knows that and I didn't bother to ask.
