When Alan put his cock into her cunt, Sara couldn't feel very much; her pussy had been stretched out by Ricky. Alan pulled out, and then Sara felt the head of his dick against her asshole. She stiffened up.
- Sara, don't you want it? Alan asked.
- I've never had anal sex before! said Sara. I'm afraid it's gonna hurt.
- I'll be gentle, promised Alan. Please? Open up and let me in, Sara! Your ass is si hot and sexy, I want to fuck it, so much!
- OK, I'll try, said Sara. But be careful!
She relaxed her ass as much as she could. Jason and Duncan were both jerking off, as they and Ricky watched Alan slowly pushing his slim dick into Sara's ass. She whimpered out of pain.
- Relax and let me in, said Alan in a soothing voice.
- I'm trying! said Sara. It hurts!
- Play with yourself! said Ricky. Enjoy it!
Sara put a hand on her clit and rubbed the tiny nub in circular motions, as Alan got the last two inches inside of her ass.
- Are you OK? he asked.
- Yeah, said Sara. How does it feel, Alan?
- Your ass feels tight, said Alan. It's not as soft and wet as your cunt, but it's really, really tight!
He fucked her slowly, groaning for each push.
- It feels strange, said Sara, smiling. Not painful, just... strange.
- You'll get used to it, said Ricky.
Alan had been holding out the longest of the 4; now he could feel that it was going to be a very short act. He fucked Sara's ass faster, groaning, he couldn't think, couldn't hear, couldn't speak... The only thing that existed right then was his cock fucking Sara in the ass, fucking his friend in her asshole!
When he came, he pulled out, pulled the condom off, and sprayed his hot cum over Sara's big globes. In the corner of his eye, he could see Jason coming, and Duncan let Sara take his load in her mouth.
