Trío nocturno

I have been wanting to fuck my step-sister since her stepmom married my stepdad. I know she heard me fucking girls here and there. One night our parents had left for a date and I was in the living room watching TV. So she and her and her best friend came to see what I was doing. They joined me and she immediately started to rub on my leg and bend over, I could see she didn’t have any panties on. She got down on her knees while her friend wasn’t looking. She pulled my dick out and my dick was already hard from watching her bend over. I tried to stop her but she wasn’t going to take no for an answer. She started to suck my dick and her friend must have heard the slurping because she turned around. She didn’t stop and she told her It was just there so I sucked it. To my surprise she joined her and they took turns sucking my dick. Kissing and sucking and they even tasted each others pussies.
