Zack takes a risk

Ashley bent down and licked the shaft of Brandon's cock with a flat wide tongue while her hand pumped the head. Brandon groaned loudly. Perfect, Ashley thought to herself, he'll never hear the door opening.

She expected to hear the door being eased open any moment but instead she felt something warm and fleshy rubbing against the crack of her ass. She pulled her mouth from Brandon's cock and looked over her shoulder.

Zack was standing behind her, cock in hand, rubbing it against her ass. Her eyes widened as she realised that Zack planned to fuck her right in front of her boyfriend, even if he couldn't see. But she bit her lip, seeing that thick cock again.

While Ashley continued to jerk Brandon's cock, Zack let a glob of saliva drop onto her asshole. Then he used his cockhead to smear the fluid all around her rim. But thanks to all of the build up he'd done not so long ago, she was practically good to go. As he pressed the tip against her hole, he felt it widening more readily than it had done before. A bit more pressure and he was in.

"Ohm," Ashley moaned as the cockhead slipped past her ring and she once again felt her ass being stretched out by Zack's thick meat.

Brandon lifted his head slightly even though he couldn't see anything. "Is everything alright, Ash?"

"Huh, oh yeah...yeeeeaaah,it's goooood," Ashley drawled out amidst the pleasure. "I'm just...oh,hmm...just touching myself while I stroke you. This hard cock has gotten me all wet."

Zack noticed that she didn't specify which hard cock had gotten her all wet. But he was more focused on sinking as much of his hard cock into her asshole as he could. Repeating his technique from last time, he gently thrust into her ass, back and forth, pushing a bit more of his thick dick into her tight back hole every time he did so. Finally he was back where he'd left off, cock buried to the hilt in her ass, his balls resting against her pussy.

Meanwhile, Ashley had stuck the head of Brandon's dick in her mouth, suckling on the tip while her hand pumped the shaft. This was mostly to keep Brandon entertained and distracted while one of his best friends stuffed their cock in her tiny back door, but it was also to stop herself from moaning like crazy because of the exact same reason. She couldn't stop herself from moaning completely, but she could muffle it with Brandon's cock head.

Brandon was loving this. He couldn't see anything but that only seemed to heighten the sensations he was feeling on his dick; Ashley's hand frantically pulling on his shaft while her mouth covered the cockhead. And as she touched herself, her moans reverberated through his entire dick.

What he couldn't see was that it was Zack making her moan as he began sliding his cock back out of Ashley's ass. She expected him to stop at the rim but Zack pulled his entire cock out of her ass. Ashley had to pull her mouth from Brandon's cock to gasp when she felt the emptiness. But it wasn't empty for long. Zack pressed his cock back into her butt, pushing quickly past the rim now and sliding himself right into the hilt again.

Zack did this several times, fully penetrating Ashley's ass with the entirety of his thick cock and then pulling all the way out only to shove it back in again. Ashley's asshole was widening significantly, moulding itself to Zack's thick shape, until he was able to thrust in and out of her in quick succession without very much resistance at all.

Ashley went back to sucking on Brandon's tip, enjoying the stretching of her asshole but being careful not to neglect her boyfriend for fear of him ripping off her bikini bottoms and seeing what she was really up to. But the idea of being caught did arouse her a little. Wasn't that why she had blew Brandon in the woods the other day? Hadn't see wanted to be seen and jerked off to? She imagined she was back there now but with Zack and he was fucking her ass and instead of Zack it was Brandon hiding behind the tree, rubbing his dick to Ashley being penetrated so deeply by such a thick cock.

An orgasm rippled through her body and as her pussy twitched Zack felt her asshole clench, squeezing his thick cock. Brandon felt the orgasm too as she squealed delightedly on to his cock. She was really getting off on this blindfolded thing he thought.

Grabbing her hips, Zack began fucking Ashley's ass in earnest, his cock sliding in and out of her butthole with speed now. Ashley bucked back against his cock, bouncing her ass up and down his shaft in time with his thrusts. Brandon felt this too, his cock being pulled back and forth as Ashley continued to suck and pull on it.

Zack was thrusting so hard now that his balls were slapping against her cunt. Their bodies made wet, fleshy sounds as they bounced off each other. Ashley wondered how Brandon couldn't hear the sound of their sex, how he wouldn't recognise the sounds of two horny bodies being slammed together. She was trying to cover the sound of their cheating, slurping loudly at the pre-cum covering his cock but to her the sound of their bodies together was louder than anything else in that room.

Brandon was simply too caught up in the feeling of Ashley's mouth on his dick that everything else just seemed distant and inconsequential to him. Somewhere in the back of his mind he heard the slapping of flesh against flesh, the unmistakable sound of sex but who cares his mind said. What's more important that the amazing blow job your loving girlfriend is giving you?

Of course that loving girlfriend was also being fucked in the ass while she blew him. As another orgasm surged through Ashley, Zack felt her ass tighten around his cock again and he knew he wouldn't last much longer. Continuing to thrust his cock inside her ass, he reached up with a free hand and tapped her shoulder. Ashley pulled her mouth from Brandon's cock and looked back at the man with his cock in her ass.

"You gonna cum?" Ashley asked, figuring there was only one reason for his interuption.

"Fuck yeah, you're so good at that," Brandon said. Zack simply nodded.
