They were both new to this, but the thought of trying anal sex was too exciting to pass up. He knelt behind her, fondling her lips with his fingers before slowly teasing them apart. She gasped as he pushed the head of his cock against her entrance, slowly letting it sink inside her. The feeling was both strange and strangely pleasurable.
As he began to thrust in and out, she moaned with pleasure mixed with discomfort. Every time he went deeper, she felt a wave of pleasure wash over her. But with each thrust also came a fluttery feeling in her stomach, and she was sure it was only a matter of time before she farted.
Sure enough, as he pushed his cock almost all the way out, she felt a rumble building up inside her. She tried to hold it in, but the effort was futile. With a loud "PFFFT!" the air escaped from her ass, filling the room with an unmistakable stink.
Embarrassed, she turned bright red and looked at him nervously. To her surprise, he just laughed and kept thrusting. The feeling of his cock sliding in and out of her dirty asshole was addictive, and she couldn't help but moan louder with every push.
As they moved together in a primal rhythm, their passion reaching new heights, she couldn't help but let out another loud fart. This time, she didn't care if he heard or not - all that mattered was the incredible sensation coursing through her body.
Finally, with one last mighty thrust, he came deep inside her ass. As his hot seed filled her up, they collapsed onto the bed, bathed in sweat and satisfaction. She wrapped her arms around him, her heart pounding in time with her lover's.
For the first time in her life, she had experienced the intense pleasure of anal sex, complete with farting and all. Despite the initial embarrassment, this was a fantasy come true - and one that they would definitely revisit again soon.
