The sissification of Button Mash

Button stretched in the bed. That was one heck of a dream he just had.

He looked over at the alarm clock. It was 3 a.m. Odd. He normally didn't wake up at this hour. And wait, that wasn't his alarm clock!

He got up out of bed, and looked at his flank. There, where it had appeared just a few hours earlier, was a large, neon green kiss mark.

So it hadn't been a dream!

Not knowing what else to do, he crawled back in bed, laying on his back. As he did so, he bumped in to his mother, who woke up.

She stretched and yawned. "So, sweetie, did you enjoy your first time with a stallion?"

"Yeah."

"Well..." she suddenly stood over him, so that they were nose to nose. "How would you like to try a mare?"

Before he could answer her, she leaned in and began to kiss him. It wasn't like how she had kissed him on the cheek when he was younger. Her tongue twirled in his mouth, entwining with his. He felt passion, not that of a mother, but that of a lover.

His cock began to grow. Before long it brushed against her pussy. He felt her moist, hot foal maker, and it took all that he had just to not thrust in to her, break into wild abandon and pound his mom's pussy. But he would resist that urge. He couldn't give in. He would never forgive himself. It would be a sin too far.

He may not have wanted to fuck her, but his mom had other plans. Feeling her son's cock rub against her entrance decided it. She had to feel him inside of her. She threw herself back onto his cock.

Button let out a loud moan. This was far better than he had ever imagined. Her warm, tight love canal wrapped around his cock, it was too much.

His mom began moving up and down, clenching her muscles with practiced precision, nudging her son to full erection. As he reached this, he began to thrust with her. Screw wether this was wrong or not. He was going to fuck his mother!

She sat up so as to take him deeper. She moaned as he pushed against her cervix. It had been ten years, since her husband had died, infact, since a stallion had been there. And now her son, whom she had fantasized about so many nights, was inside her. The thought made her want to cum right then.

Button moaned as his mother rode his cock. Never before had he penetrated a mare, and now it was his mom, the subject of many a perverse fantasy, that was ridding him. He was lost in ecstasy.

His mom picked up the pace, and both knew it wouldn't be long before they orgasmed. Sure enough, after a few more minutes, his mom slammed down, squealing as she came. This sent Button over the edge, blowing a load directly into his mother's womb.

His mom smiled in bliss. She had forgotten what it felt like to have a stallion fill her with his seed. And, considering his size, it was a huge amount. She licked her lips, imaging how hung he would be as an adult.

Button sighed in bliss. The moment was perfect. One of his most perverse (and favorite) fantasies had just come true. Nothing could spoil it.

That's when his mom leaned in and whispered into his ear: "I'm not on any birth control."

He gasped.

"Yeah. You're gonna be a daddy!"
