Something pushes against his lips

Alex opens his mouth on instinct to let the invader in, assuming it was Emily's tongue and they were now somewhere he could please her. He was surprise to feel a familiar hardness push past his lips. Even if he wanted to he couldn't have suppressed the whorish moan that escaped his lips as he moved his head forward to take the cock into his mouth.

He felt a little disappointed to note the silicone taste but knowing it was Emily's hand pushing it into his mouth was more than enough to get past that. He took it as far as he could without gagging and tried to pull back. He felt a hand on the back of his head stopping him. "Be a good little sis and take it all." He felt the dildo push against him and after a deep breath pushed forward.

He did his best to suppress his gag reflex but kept coughing. It didn't stop Emily's pushing as he felt it touch the back of his mouth. He pulled back in a rush, coughing and gagging and feeling like a failure for not obeying his big sis. He eyes stayed closed when he heard a shaky breath come form Emily. "Wow little sis. You almost took it all. Have a look." He opened his eyes and saw a bright pink smooth dildo in front of his face. Emily had her fingers wrapped around a point a little above the base and felt really proud of himself. When she moved it back to his lips he opened up readily determined to impress her again.

This time she didn't push and let his go at his own pace. He wanted to impress he but as he took the dildo into his mouth he saw her hand enter her pants and decided to give her a show. He pulled back and licked and kiss the tip lavishing all his attention on it while staring into her eyes. She growled at him in domineering pleasure as she pull her hand from her pants and moved them to his lips. He sucked off her juices hungrily. Once clean she put them on top of his head and pushed down.

He knelt down before her as the dildo was replaced in his mouth. She pushed the base against her crotch and used her hips to push it inwards. He looked up at and got into the rhythm. Each time she thrust he used it get a little deep, when she pulled back he could breath and get ready to take it closer to his throat.

"Fuck my little femboy sis is such a slut." Her hand on his head tightened and pulled as he held back the gags. Knowing and seeing how much pleasure she was getting out of this made it much easier for him to take her fake cock closer and closer to the beginning of his throat.

When it hit the deepest part so far they both knew it and she gave him a little time. They both knew, ready or not she was going to push that fake cock into his throat. He gave a little nodded and she pulled his head and pushed her hips, pulling him forwards.

He felt it push into his throat and thankfully there was no gag. Her legs began to shake as she held him there and as she orgasmed with him staring up at her, a dildo in his throat with his lips touching the fingers holding it there she knew exactly what she was going to do to Alex next.

Alex was holding as best he could be he need to cough and gag so soon after taking it all the way. He held back to make sure his big sister was happy but as soon as her hand loosened on his head had took the dildo out of his mouth and fell to all fours coughing like crazy.

"Fuck little sis." Emily said, he looked up at from his doggy position and saw the dildo still in her hand and her eyes no longer on his face. His butt's ache returned stronger than ever and began to wiggle of its own accord begging for her attentions next.
