Humphrey was out with the kids. They were at the lake, playing or something - Kate didn't care too much. Kate and Humphrey hadn't been in love for a while, probably since the pups were growing up and they no longer had much holding them close together. They'd tried to talk it out, and they'd seen a therapist - but something that was there before just wasn't now. Kate didn't see the Omega as fun, but as immature, and Humphrey stopped seeing the Alpha as beautiful, but as ageing.

They'd done everything they could to keep it together, but nothing was working. Until now. Humphrey had proposed that they see other people for a few weeks, secretly. One night, Humphrey told Kate when the kids were asleep that he was going out to see Sweets. Kate let him go, and he knew what they did afterwards. Kate had seen how Humphrey regained the spring in his step after that night, so she wanted to try it out herself.

Part of her held her back, it told her that it was wrong even if Humphrey let her to sleep with someone when you're married. It was a betrayal of their children, of Kate's parents to be doing this. But Kate, partly for revenge, partly for pleasure, wanted to do it too. She just hadn't met anyone who she wanted to do it with. But today would change that.

A voice called for Kate from outside the den: "Kate, are you here?" It asked.

"Yes, come in." Kate invited.

In stepped a small, grey Omega - much like Humphrey. Kate saw him and was reminded of what she loved about Humphrey when they were young. He smiled, he looked playful, he looked young. It was Humphrey's friend - Shakey. "Hi Kate, I was just wondering if you'd seen Humphrey." He stated.

"No, but I'd like to talk to you." Kate told him, smiling. She wanted company badly, as she hated being alone.

"Sure." He said, walking over to sit by her. Shakey had always found Kate attractive, but he thought that Kate was all locked up by Humphrey. "What about?" He asked when sat down.

"I want to talk about Humphrey. We're not..." She stopped for a second and sighed, "in love anymore. We haven't been in a while."

"Oh, I..." Shakey began awkwardly, feeling uncomfortable to hear about his friend's marriage problems as he felt that was too personal to him.

"I need you to help me." Kate cut him off, thinking that this was her chance.

"I..." Shakey stuttered as Kate stood up and approached him.

"Please, Shakey." Kate pleaded softly, grabbing Shakey by the shoulders and pulling him into a deep kiss.

Shakey shook away for a few seconds, but did not do so when Kate went in for another kiss. Kate lay down in front of him, exposing herself. Shakey stopped himself, and thought about what a betrayal it was to sleep with your best friend's wife - but that was overpowered by sexual instinct towards the very attractive wolf lay before him, showing him her body in full.

Shakey moved to stand over Kate, and then lined himself up to enter him. Passionately, he dipped down and kissed Kate. While doing so, he entered her pussy with his cock. He grunted slightly as he put his tip in. Kate purred slightly, then moaned as Shakey loosened his kiss.

Shakey was big, and so it was hard to get every inch into Kate's tight walls. Shakey felt exhilarated when he was all the way in, and so he began to pulsate backwards and forwards. Excitedly, he panted and went quickly soon. Kate moaned loudly as Shakey speedily thrusted into her. "So big!" She moaned, feeling Shakey's chest with her paws.

Shakey stared at Kate's teats, thirsty for more pleasure. He grabbed one with his paw, making Kate chuckle. "You're so tight..." He groaned.

"Oh, fuck." Kate shouted out, loudly.

"Oh, so... tight." Shakey shouted back, worried that Humphrey was nearby and could hear them.

Shakey continued to fuck Kate's pussy, growing harder and harder with each pulsating thrust. He let out a dribble of spit, but was too tantalised by Kate's beautiful figure and body to think about his own appearance. Kate felt like the whole thing was letting out so many feelings. Feelings of disappointment and boredom. It was so exhilarating to let those feelings out. To her, it only made sense to do it with Shakey. Humphrey would be more hurt if it was done with someone he didn't know, surely?

Shakey had lost his concern that Humphrey was nearby, and tried to get as much out of the experience as possible. He loved every second of pounding Kate's tight, wet hole. It was so sexy that he felt himself get close fairly early. Trying to contain himself, he slowed down slightly and focused on playing with Kate's teats. Kate had almost zoned-out with the pleasure, and was moaning lightly.

Shakey's panting was rapid, and his thirst for pussy was inquenchable. He couldn't hold it in too much longer, and so he began to feel himself climax. He panicked and shoved his knot in quickly. Kate winced, but soon relaxed. Shakey came in long, hot strings. It was smooth and warm and made Kate feel like her pussy was filled with silk. So pleasurable was the cum inside of her, that she ordered Shakey to keep his knot in a little longer.

Kate orgasmed loudly and powerfully, rubbing her lips around Shakey's knot until she felt it pass over fully. She let out her own juices onto Shakey' cock. Shakey was not done with Kate yet, however. He pulled out of Kate and starting to talk to her. "Can we do more?" He asked.

"Sure." Kate responded, out of breath like Shakey.

Kate stood up and turned around, lifting her tail up and showing her ass and her wet pussy. Shakey viscerally mounted Kate and tried to enter her. He first tried her pussy again, but the cum made it to slippery to enter. Instead, he ended up pushing it into her ass. Kate winced more as Shakey pushed in quickly. His fears of Humphrey finding them were rekindled, but still not enough to discourage him.

He humped Kate very quickly, making him feel intense pleasure. The power of his thrusts threw Kate a bit off balance, but she was certainly strong enough to let him continue without any major problems. Kate's body was reeling from the constant thrusting, but she was getting to much pleasure to really notice. He felt himself come close again, and so shoved in his knot once more. His cum was as silkily as before.

As soon as he pulled out the second time, Shakey stood up. "Thanks, that was great." He acknowledged to Kate. Kate nodded. Shakey darted his head from side to side and sprinted out, making sure he wasn't seen leaving Kate's den. He took precaution when leaving, immediately going toward his own den. Kate went to the lake, but returned a few minutes later after letting all the cum out.

When Humphrey and the kids came home later that day, Humphrey noticed the smell. He told the kids to play outside while he talked to Kate. Kate was still sleeping in the back of the den, and as Humphrey approached he sighed - knowing that she'd done as he'd done. He was pained for a while, but as she slept he looked at her like he had before they married: the attractive female who he was lucky ever gave him a chance.

As Kate awoke, she saw Humphrey sitting beside her. She sat up too, and kissed him on the cheek. "Humphrey, I think I've had a long enough break from you. Let's give it another go together."

Humphrey smiled and they embraced. "Hey, one question," Humphrey began, "who was it with?"
