All three of us fell asleep in the same bed all tangled up with each other. It took me a few minutes longer to fall asleep. You see, I had never had a cock this big in my ass hole so I was a bit sore but I felt really good. After my ass hole stopped throbbing and calmed down a bit I fell asleep too. I woke up late to find that both my uncle and my sister are out of bed already. I quickly got up, brushed my teeth and went to the kitchen. My sister was bent over the sink, her shorts were around her ankles, she had no panties on, but her tee shirt was still on. My uncle had his boxers on the floor and his tee shirt was still on too. My uncle had his hands around my sister's waist, her ass was sticking out, her ass cheeks were spread and my uncle's fat cock was shoved up her tight little ass hole. She was fingering her pussy too while gyrating her ass to feel our uncle's cock better in her tight little ass hole. Its not every day you get to see two hot looking people fuck like this. My pussy started creaming right away. I had to join in.
You see we are innocent looking girls but we are very dirty. Me and my sister have spent a lot time with each other learning and playing. Watching my sister bent over the sink like this and taking a big fat hard cock up her ass hole and watching my uncle spread his legs wide enough so he can balance himself as he pounded into my sister gave me a very naughty idea. I walked up behind my uncle, took off my boxers, got down on my knees behind him and started cupping his giant shaved balls. He gave a loud moan when he felt his naughty niece's soft hands on his balls massaging him. As I massaged his balls I got turned on even more watching his fat cock sliding in and out of my sister's ass hole. It was so tight and so sexy to watch that. As I was lost in the view of my sister's ass hole getting rimmed from behind, I realized that my uncle's crack and ass hole were fully shaved too.
His puckered ass hole was pink. That hot little piece of ass hole was star-like, tight and pink. I could not resist. I quickly put a finger in my mouth and shoved it in my uncle's ass hole. His ass hole tightened around my finger and he rammed his cock deeper into my sister. I guess he liked having his ass hole played with. I really enjoyed finger fucking my uncle while he fucked my sister. At one point I was shoving my finger up his anus so hard that it was pushing his cock into my sister's ass hole deeper just by the force of that. I was hot but I wanted more. Since last night's ass fucking it was only fair that I return the favor of my uncle eating my ass hole. So I quickly shoved the tip of my tongue on his puckered ass hole.
Talk about a reaction. As if thousands watts of electricity went through my uncle's body, he jerked and started bucking and shoving his cock in my sister's ass hole harder and faster. My uncle started talking really dirty to me and calling me names. He called me "his anal slut" and "his ass licking whore" I don't know what happened to me but I shoved my tongue in my uncle's hole deep and hard. Even my sister figured out what was going on and she told me "God damn bitch lick his fucking ass hole" That was all I needed. I really got into it. I started massaging his balls faster, kneading them and shoving my tongue in and out of his tight little ass hole. He grunted and whimpered and started cumming inside my sister's ass hole. My sister screamed that our uncle's fat cock was spurting thick cum into her anus and that it felt great. I got really into it some more. I fucked his ass hole deeper and harder. I milked his balls to squeeze more juice out of them. After a few minutes of pure fucking I removed my tongue out of my uncle's ass hole and watched as he slid his fat wet cock out of my sister's ass hole. That was my sign to stay down there and suck his cock wet with my sister's anus and his cream. After I cleaned his cock I shoved my tongue in my sister's ass hole to make sure I drink all of my uncle's cum juices out of her.
We were all tired. After we kissed each other we all sat down for breakfast and teased each other and laughed and giggled. My sister started describing how hot it felt to be fucked bent over like that and how it felt to have my hands massaging his balls and touching my sister's pussy. I described what my uncle's ass hole and dangling balls looked like when I walked in the kitchen. I told them how I felt and how out of control I was that made me want to lick his puckered ass hole. All my sister could say was she can't wait for her turn to tongue fuck our uncle's hot little ass hole. All my uncle could say was "promises promises."
