Sara by Sara

Sally then said, “Sara, Sam and I are going to show you how to fuck.” I was jarred by her directness, and also that she would be doing this with Sam. We really were one big happy love family.
Sara got on her back and pulled off her panties. She had the cutest little cunt, and I felt a pang of jealousy. Sam hoisted her legs high into the air, exposing her asshole, as I lay on my side looking at them. George again pressed his raging erection against my ass.
To my great surprise, Sam took some of the lube I’d bought at the store and slowly went to work on Sally’s anus. Then I realized what Sally meant. She was going to show ME how to fuck…in the only way I could. And it was apparent from the urgency of George’s thrusts against my backside that he intended to be the beneficiary of Sally’s instructive endeavors.
Slowly Sam worked one finger, then two, into Sally’s ass. Her hips bucked. Sam pulled out the dildo and gently pressed the head against Sally’s lubed anus. He then propped Sally’s head up, and she took a long slow drag from the brown bottle. She laid back and her asshole instantly relaxed. Soon the dildo was thrusting in and out, rhythmically, methodically. Sally looked pleased as she played with her clit. Sam then removed the dildo, and propped Sally’s ass up on two pillows. Her asshole was now at the perfect angle to receive her cock. Sam mounted her, and Sally moaned. As his thrusts grew deeper and more purposeful, she let out a collage of squeals and moans and gasps that seemed like its own language…the language of anal sex. In the midst of this, and with no warning, Sam removed himself, and flipped Sally over on his tummy. I had become so engrossed in what I was watching that I only then noticed that George had pulled my panties down below my ass, and the head of his lubed cock was gently probing my hole. I wanted it…I think.
As Sam resumed working Sally over she reached out and held my hand. She pulled me closer and kissed me tenderly as Sam plunged in and out of her ass. Her expression was a strange admixture of crazed ecstasy and sublime submission. After we kissed, she handed me the bottle. “Take two really long hits, and take care of my George for me,sweetheart. Can you do that for Sally?”
