They should

He moaned as Kay sucked his cock into her mouth, her dark lips framing his pale cock. “God, that feels incredible,” he gasped.

Kay resisted the urge to smile as Steve continued to watch outside. Jan grasped Gen’s big cock and was feeding it into her cunt. She was moaning loudly as the thick cock slowly parted her lips.

As their lovemaking grew louder, Kay pulled her head back off Steve’s cock, “She seems to be enjoying her breeding.” She teased. Her screams of pleasure indeed suggested she was enjoying herself, and so Steve leant back and watched as Kay slowly blew him.

Kay pushed her head down on his cock, taking him into her throat as she massaged his balls. She occasionally swallowed, letting the muscles of her throat please his cock.

The screams from outside grew louder as Steve’s cock throbbed in Kay’s mouth. She pulled back to breathe, “You like this, don’t you?” She asked, stroking his cock, “You like watching my husband fuck Jan with that enormous cock?” His cock pulsed in response.

“Yes,” he gasped. He couldn’t believe he was watching his soon to be wife fucking another man, let alone a Mythfolk, and she was loving it. He wondered how things would change before their wedding and then shuddered his wedding. Ten weeks away, they were going to get married ten weeks before their honeymoon.

Then he realised it. They had timed their honeymoon around Jan’s infertile period. “Oh my God,” he shuddered and shook as he grabbed Kay’s head, instinctively holding her there to prolong the pleasure. “I think she’s fertile,” he said.

He felt Kay moan and let her head go. She leant back and smiled up at him, slowly licking her dark lips. “So, they should stop?” she asked. Before gently sucking on his cock head.

“Yes, we should stop them,” he moaned at her touch, still struggling to actually move to stop Jan from being bred by his centaur neighbour.

A cry came from the backyard from both participants, and Kay pulled back again. “Gen is close. I know those screams. He is about to fill your lovely fiancé with his hot steamy cum.” She teased, stroking his cock.

“God,” he pulled himself away from Kay with great difficulty and ran to the back door. He stepped out into the backyard and could see that Jan was shuddering in constant orgasm. “Jan, Mythfolk can breed with humans,” he said as he stepped down onto the grass, Kay close behind him.

Jan looked over at her fiancé, and his face was a mask of arousal. Her fingers dug into the earth as she locked eyes with Steve. She knew him. His logical mind warred with his passions. “God. Cum for me, Gen, knock me up,” she said, never taking her eyes off of Steve.

Steve groaned loudly enough for both Gen and Jan to hear it over their own cries of pleasure.

Steve saw it all happen in slow motion. He felt Kay’s hand on his shoulder as he saw Gen’s massive balls tense and his shaft throb. Jan’s eyes rolled back as she gasped, “So hot.”

Steve could see Gen’s cock throb, again and again, each time Jan shuddered and begged for more. Cum spewed out of her overfilled cunt as she continued to call for more. “Yes, fucking breed me, please, breed me.”

As the lovers in the backyard started to pant, Kay stepped in front of Steve and lay down on her flank. She looked over her shoulder at Steve and smiled, “I think it’s your turn,” she said softly.

He heard Jan moan, “Please, Steve, fuck Kay, I want to see it.”

Steve knelt behind Kay and moved her tail to the side as Jan slowly crawled out from under Gen. She watched him as he slowly pushed into Kay’s cunt, and Jan bit her lip. Steve could see how aroused she was.

As Jen continued to watch, she squatted under Gen, pulling his cock, still oozing cum, to her lips. She started to suck and lick it clean. As she did, Steve watched Gen’s cum drip from her cunt.

Kay turned to look at Jan and smiled as she moaned, “I think we have some very nice neighbours,” she said. “And I like the feeling of you inside me.”

Steve was holding one of her legs while thrusting into her as Gen watched on. “Kay is a magnificent fuck, but I much say I did enjoy Jan.”

Steve shuddered, and Kay giggled, “He likes hearing that you enjoyed his fiancé, dear.”

Jan pulled her head back from Gen’s cock and looked at Steve, “I enjoyed it too. In fact, I might get addicted,” she confessed.

Steve shuddered as Jan went back to lovingly sucking the centaur cock clean. “God, I can’t believe you let him cum in you. What if you get pregnant?” he asked, still fucking Kay.

Jan crawled out from underneath Gen and walked over to Kay and Steve. “You enjoyed it too, you could have told me to stop, but you just told me I could get pregnant.” She leaned down and kissed Kay softly on the lips. It was the first time Steve had ever seen Jan do anything with a woman. “If you really wanted me to stop, you would have said so. Now, are you going to knock up Kay?”

Kay laughed, “I’m not fertile yet.”

The addition of yet caused Steve to shudder again, and Kay giggled, “Oh, he liked that, oh it feels so nice,” she moaned as Steve held himself within her cumming.

Kay’s cunt continued to milk him through her own orgasm, and Steve was amazed that he didn’t soften. As he started to fuck her again, the sensation was intensified, her cunt, slick with his cum, sucking at her every time he pulled back. “Oh, Jan dear, I think Steve wants to go again,” she said. Then she pointed to her husband, “I think Gen does as well.”

Jan turned to see Gen’s cock was hardening again, and she sauntered over to him. “So Gen, while Steve fucks your wife, do you want to fuck my cunt again? Or would you rather fuck my tits and mouth?”

Gen looked over at Steve, who was again shuddering in pleasure, he wasn’t capable of cumming again yet, but he wanted to.
