My brother and I always joked about how hot our aunt was but we rarely ever got to see her. Since her divorce though she’s been coming over quite regularly now.

when I heard commotion coming from the living room, I went down to see what was happening. i couldn’t believe it. here i was, watching my aunt bouncing up and down on my little brother’s big cock. my mom was behind her, laughing and spanking her as she rode him.

What in the FUCK is going on here?”, I said, shocked.

Mom looked over at me while my aunt continued bouncing on his cock, “don’t be jealous, it’s unbecoming. your brother’s big cock would be enough to satisfy her… your tiny little one wouldn’t do anything. you know, why don’t you stay and watch so you can learn that only boys with real cocks get to fuck.

After a few more minutes of watching her sister and her son fuck, apparently mom couldn’t take it.

“Honey”, mom said to my brother. “Would it be okay if mommy had a turn? I haven’t had anything that big in a while and could really use it.”

“Sure mom!”, he said with a smile. 

As my aunt was getting off of him she smirked at mom, “you’re fucking disgusting”, she said while her pussy was still trembling from her previous orgasms.

“Shut the fuck up”, mom said half heartedly. “Why don’t you put that whore mouth of yours to good use and get between his legs and suck on his balls while I fuck him.”

They both laughed but my aunt took mom’s suggestion and went to the floor between his legs.

For the next 2 hours they took turns orgasming on his big cock while I watched.
