It was a wonderful day for a walk through the forest, which is why I'm out here with my friend and mate Sasha the fox. My name is Kai. I am a human male of average height and build with a nicely sized tool. My hair is blond and my eyes are blue. Sasha is a normal looking red fox female with a spirited personality. We travel along the path until we come across a clearing next to a creek, our favorite mating spot. Sasha starts to get frisky and run under my feet, brushing her tail against my crotch as she makes a pass. I put down the backpack and catch her as she jumps at my chest. Holding her up with my hands on her rump and lower back with her rear paws against my stomach gave me an idea. I unzipped my pants and pulled out my already stiff cock and sat down with Sasha held up above my lap. She licked my face as I started to finger her. Her warm pussy was already very wet. At first I was confused as to why she was so horny, and then it hit me. She was in heat. The thought dawned as se reached a climax. Sasha thrust down onto my finger rapidly and hard enough to make me worry that I might hurt her, but she knew what she was doing, so I held my finger in place and enjoyed the orgasmic convulsions of her wanting body teasing my finger. After a few minutes of playing with her I sat her down on my member. It easily glided into her hot pussy. I moaned as she squeezed and squirmed around me. She eventually settled down and started to lick me. I opened my mouth and we kissed passionately for what felt like a day, then she pushed against my stomach with her hind paws and plopped back down, pushing my entire length into her. At first I was worried that she couldn't handle it without more stretching, but her panting smile told me otherwise. So I started pumping my hips upwards into her rump causing my shaft to move around inside Sasha's body in a stirring motion. She responded by clenching and humping against me. We kept it up for hours. As I finally reached my first orgasm I snuggled into her chest and held her as I came inside her. The over flowing pressure made cum drip down my balls and onto the grass. After a few minutes Sasha jumped from my lap and ran to the water. She came back after she got a drink and showed her rear to me with her tail up high. I fell to my elbows and held her haunches with my fingers and licked her dripping pussy. I used my thumbs t hold her lips apart and pushed my tongue as deep as I could. Sasha pushed back against me trying to get me deeper, but when my tongue wasn't enough she pulled away and positioned herself under me with her butt against my once again throbbing cock. She seemed determined so I gave in and slid back into her and, holding her with one hand, started fucking her like a male fox would. I thrust into her so hard and fast that she had a hard time keeping her footing. So I held her up to my chest and lay on my side without pulling out of her, then I started bouncing her up and down while I slammed into her. Her sighing pants were almost enough to send me over the edge, but I held out until she climaxed. This orgasm was a big one. Sasha had started thrusting down onto my dick and I couldn't help but thrust back then I felt the tip of my dick push through the opening of her cervix. As I came she kept pushing down and pushing me into her womb until she pushed the head all the way in. She stayed there and let me fill her womb directly with my seed. When I finished her tummy had a small budge where cum was trapped inside her. I rubbed my hand over that spot until we fell asleep, still curled up in a small patch of sunlit grass.
