My friend and I were assigned to do a project with my step sister Amethyst. Not surprising, she wouldn’t do a single thing and she was the hardest person to work with. While we weren’t paying attention, my step sister crawls under the table in skimpy revealing clothes. My friend and I were startled, she pulls our cocks out, and starts sucking them. At this point we can’t say anything, she’s already spitting on them, sucking our balls, and being a messy little whore. We decide to take advantage of the situation, taking her clothes off, and using her mouth and pussy on the table. Finally we had enough, we bend her over, and fuck them both till we fill both sides up with cum.
