Step-Sister's Free Use Weekend

I haven’t seen my step-brother in a while so I was kind of excited when he called and asked to stay for the weekend. There is just one tiny little thing he doesn’t know about his step-sister… I have a free use house. My boyfriend is allowed to touch and use my body whenever he needs to. He fucks me when I play video games with friends, while doing the laundry or dishes or even when I am cooking in the kitchen. It’s just our relationship and we both have a thing for it. I was shocked when my boyfriend said he wasn’t going to stop when my step-brother showed up. I mean, it’s my step-brother! He can’t know or see his step-sister having sex, let alone FREE USE SEX! What would he think of me?! It’s only a few days.. I think my boyfriend can hold out. My step-brother shows up and we get settled in. In the evening, we decide to play a board game and my boyfriend is adamant about me touching his cock under the table while playing. He even shoves my head down to suck his cock during his turn. I can’t believe he’s just doing this in front of him. I just pretend to not know what is happening and let my boyfriend do what he wants. My step-brother says he needs to use the bathroom and that’s when my man goes all out. I suck him until he busts a huge load all over my face. I’m not sure if my step-brother saw what just happened or how long he has been there but I have to play this off. I can’t believe he’s asked me if I just got a facial!!!
