Fucking Ashley's ass

"Yes Zack, fuck my ass," Ashley demanded.

Cock in hand, Zack placed the tip of his cock on the edge of her asshole. He rubbed the ring with his cockhead, smearing pre-cum all over her twitching hole. Then, holding his cock steady, he began to press the helmet into her ass, using his hips to keep his movement steady and measured.

Ashley inhaled sharply as she felt the cock moving against her asshole. While Zack had widened her back door significantly there was nothing on his body quite as thick or hard as his cock. She reached down with her hands under her legs and pulled at her butt cheeks, trying to aid in the opening as much as possible. But even with that, Ashley felt her asshole resisting the large cockhead.

Zack eased off the pressure, allowing her asshole to grow accustomed to the stretching. Then he pressed against her, slightly harder this time, feeling the pretty little butthole open a bit more for him.

He looked up at Ashley's face. She was moaning breathlessly at being stretched open by his cock. She looked up and caught his eye, sharing eye contact as Zack pushed steadily into her ass. It was weird for Ashley. The only time she'd ever felt her asshole stretch open like this was if she was taking a particularly large shit. So this should have felt kind of gross, but instead it felt nice. Maybe it was because it was going in rather than out, or maybe it was because the object sliding past her butthole was warm and fleshy, or perhaps it was just because it belonged to Zack. Ashley was surprised that a cock in her ass could feel this good.

Of course it wasn't quite in her ass just yet, but as Ashley reflected on how enjoyable the feeling of having her asshole stretched out by Zack's hard cock actually was, she felt the helmet slip inside completely. Zack watched as her asshole engulfed his entire cock head, the ring contracting and around his shaft just below.

"Ah, yeah," Ashley moaned as Zack held himself inside her for a few seconds allowing her ass to adjust and relax again. Then he started thrusting, short, rhythmic stabbing motions with his cock, plunging his cock deeper into her asshole little by little. It was a long process because Ashley's ass was so tight and Zack's cock was quite thick but Zack pressed on, piercing her butthole with his dick, continually stretching her open and enjoying the feeling of her walls tightening and constricting around his shaft. After several minutes, he had buried himself completely in Ashley's ass, his balls resting against her crack.

"Oooh," Ashley whimpered happily, enjoying the full feeling inside her ass.

At precisely that moment there was a knock at the door.

"Ashley? Are you in there?" It was Brandon's voice.

Ashley's eyes went wide and she looked to Zack. Zack had much the same look of bewilderment as she did. Then they heard the door handle.

"Wait. Don't come in," Ashley said quickly. Zack quickly pulled his cock out of her ass. Ashley gasped at the sudden removal, feeling her ass twitch around the vacuum. As the cockhead exited her asshole it made a loud, wet pop that Ashley and Zack were certain that Brandon must have heard.

"What? Why? What's going on?" He asked from the ajar door.

"It...it's a surprise," she said, gingerly getting to her feet while Zack gathered up their discarded clothes.
