Megan pulled out of Will's dick and stepped backwards, feeling off balance. She couldn't help but open her mouth and put her hands on her hips as bones harmlessly creaked and flesh moved. Grey fur began to lightly coat her where before her mound was clean shaven and a tail pushed it's way out of the base of her spine. Will noticed her posture became slightly stooped, her hips seeming to not let her stand up completely straight. Megan put a hand down her crotch and felt her sex move farther back... becoming plump and quite a bit larger. Her fingers slid around, finding the feeling of her new labia strange. It was huge. She felt her ass with both hands and noticed her hips getting ridiculously wide. One hand returning to inspection via front, she noticed her thigh gap was more like a thigh gorge. She could fit her arm between her legs no problem! While that hand returned to feeling her large, teardrop-shaped donkey vagina, the other inspected the tail. She felt the length of it and swished it around, then felt the base and her fingers found her new asshole. That was pretty different, as well, having puckered out and come to rest right beneath her tail. All in all, things were very interesting and she was wet with anticipation.
Looking up at Will, she weakly smiled. He got up and took her hands. "Maybe lean on the table?"
"That sounds good," she replied. They walked forward the few steps and Megan put all her torso's weight down, moving the computer into the middle of the table. It was now right in front of her. Megan's proudly showing donkey vagina was right in front of Will.
Megan gasped in joy as he plunged into the wet folds. They trembled in pleasure, both very conscious of just how deep Will was entering. He moved closer until they were hip to hip, completely filling Megan. Her tail went over his shoulder and he began to rhythmically grind. Megan planted her face on the table and gripped her large breasts, pinching the nipples slightly and drooling onto the wood. Will felt his testes rocking forward and back with the movement and they both felt the brush of fur around their delicates... although much less delicate, now.
Will picked up the pace, grabbing her waist to pull himself in. Megan arched her back into the table, moving the path of the glorious shaft around. They were both coming closer to the end of the raw sex, Will breathing loudly through his mouth and Megan moaning on the table. Ramming her very fast, Will was feeling the pressure inside grow. The valves and tubes and sphincters holding back his seed were waiting for the sensations to mount and break his body's automatic resistance to immediate release... until the moment came! So Will came (gobs of cum. It spilled out onto the floor, out of her tunnel, from around his cock); Megan came (screaming in delight, her new vagina gripping the donkey dick which was so warm and made her insides alight with fire).
Will pushed himself inwards one more time, shoving Megan roughly against the table. Her face and torso slid along the well-oiled (and drooled on) wood, her thighs coming to rest against the edge. She stayed there as Will pulled out, barely finding the chair and not crushing his tail as he sat down, satiated and exhausted.
They stayed like that as the sun started to shine though the windows on the other side of the house, low beams of warm light finding their way into the room where they were.
"Good morning." said Will.
"Love you, too." replied Megan. She but her lip and felt the cum inside her. Looking up, she saw the laptop and the chronivac program still running on it. She was hungry and knew Will was, too - them both having skipped dinner. Maybe it was time to go make waffles and think about the day. Maybe it was time to turn the dominancy tables on Will. Maybe it was just time to have another round of amazing sex.
