Mom fucked bare by stairbrother in the bedroom, naked woman on top

As soon as I entered the bedroom, my mom could see the excitement bubbling within me at the thought of watching her get fucked naked by my older brother in doggy position.She immediately grabbed my phone and showed me a video of her being fucked hard in the nude on a bed.Her thick bubblegum lips were clenched tight around his cock, her pussy muscles contracting around his hard shaft as he drove his cock deep into her.I couldnt help but feel a bit jealous that she was getting filled up by my older bro, but I was too eager to witness it firsthand.With every stroke, my brothers muscles flexed as he pounded her pussy harder.My mom screamed out loud with pleasure as my brothers face buried itself deep into her neck.The sight of my own mother being so dominated by her own brother was intense, and I couldnt take my eyes off of her beautiful tits bouncing up and down on the bed.As they continued to fucking, my sister walked in unannounced.She looked shocked at what she was seeing and quickly retreated back to her room, but before I could catch up with her, my mom grabbed hold of my cock and dragged me over to my brother and whispered show her what it means to ride cock in my ear.I looked up and saw my sister sitting on the edge of the bed, staring hungrily at my brother.I pulled her onto my lap and started grinding against her as my brother continued to fucking my mom from behind.Suddenly, he let go of my mom and pulled out of her and went to lie next to my sister.He rubbed his still hard dick up against her leg and told her that he wanted to watch us ride him together.She looked hesitant at first, but after some persuading from me, she got up from her seat and straddled my brother.She threw her arms up as I thrust inside her hard, pulling her closer to me as we both moaned loudly together.After a few more minutes, my brother finally pulled her pussy lips wide enough to allow me to thrust my cock deep into hers.We all groaned loudly in pleasure as I felt my orgasm building rapidly within me.As I exploded all over my sisters asshole, my mom turned around and smiled triumphantly at me as she saw me finally find release.I couldnt help but think that my mom had taken great pleasure in watching this entire scene unfold.It made me want to explore more ways to spice up our family dynamic and bring us all closer together through sexual activity.
