After Ty closed the bedroom door and made sure the one-way soundproofing was in place, he asked Lisa, "How did you like Settlers of Catan? I've got wood for your sheep!"
"It was fine for good, clean family fun," she replied, "but now it's time for _dirty_ fun!"
She rapidly undressed, walked over to the bed, lay down, shoved the pillows off, and immediately started transforming. She once again became a furry mattress topper, this time with four breasts with pussies, and a genital mound with two pussies, but no face or ears. He heard zipper sounds, and six tongues emerged and started licking her pussy lips and clits. Her tongues then extended further, started instead licking the pussy lips of their adjacent pussies instead, and then plunged into those pussies and started thrusting.
Ty was fascinated to watch all of this activity. After a moment, he started rubbing her furry surface with both hands. As he started pushing downward, the motion suddenly stopped." That must be an orgasm, he thoigh. He lifted his hand, and after a moment the tongues got to work again.
Her breasts and pussies were closer to one side of the bed than the other, leaving room for him to lie down without being on top of them, if he wanted. He undressed, picked up a pillow, sat on her, which caused her another orgasm, and lay down with his head on the pillow. His body transformed again to almost hers, with his facial features somewhat feminized, four arms, four breasts with nipples, and two enormous cocks. He started masturbating with two hand son each cock, and noticed that her tongues sped up as his hands did. He soon reached climax, and saw that she did as well. Her tongue activity stopped for a while, then restarted, slowly.
He sat up, tossed the pillow off the bead, and waving his arm, gave her two more breasts, above both pairs she already had. These ones had neither nipples nor pussies, though, and they were covered with her silky white fur, like most of her body now was. He concentrated, and the two furry breasts move upward, closer to the head of the bed, and grew in size, until they were each rectangular, half the width of the bed, about 18 inches top to bottom, and about five inches thick, top surface to her main surface. He lay back down, resting his head on one of her new pillows. She must have enjoyed that, as she orgasmed again, then resumed pleasuring herself.
He watched the show for a longer, then turned his nipples to giant cocks again, rolled over on top of her other side with the body parts, and penetrated all six of her pussies again. He started thrusting. Before long he was near climax, and started edging. Mattress topper Lisa had several more orgasms, befo4e he finally came, giving her another.
He rolled back over to her less featureful side. With two hands, he massaged her breasts, occasionally switching to different ones, then started stroking her clits. Her tongues worked on the pussies he wasn't stroking at any given time. After she orgasmed again. her tongues remained extended, but went limp, just lying on her breasts and crotch. Ty assumed that meant she was tired, and had enough sex for now. He withdrew his hands, and lay there resting. After a while, he heard zipping noises again, and looked over. She had retracted her tounges, zipped her pussies, and as he watched, the four breasts and crotch mound, melted away into her body, replaced by the white fur. Now her only visible features were her two pillow breasts.
Ty tuned off the light, and went to sleep.
At some point in the night, he needed to go to the bathroom. He quietly stood up, and saw no sign that he had awakened Lisa. However, when he got back from the bathroom, he saw that she had breasts and crotch mound again, and all six tongues were standing up and making beckoning motions. Happily, he climbed back onto her, and they proceeded to fuck their brains out again. Once they'd both orgasmed, he rolled back over to her blank side. He heard the zippers again, and saw the beasts and crotch disappear again.
A few hours later, he was awakened by zipper sounds, and they went at it again. This is awesome, he though, unaware that Lisa was thinking exactly the same thing.
Around 7:30, he woke up with morning wood. He rubbed her fur where her crotch mound had been, and that mound and the breasts grew back, and the tongues unzipped her pussies, for another round. This is the best way to deal with morning wood, he thought.
After, he got up, and saw her tongues languorously licking her lips and clits again. He went to the bathroom, came back, and saw that the tongues were still going. He sat on her other side, causing the tongues to stop for a bit. Then he heard her voice.
"Good morning," she said, "or perhaps more accurately, great morning!" Her face was back, with a big smile. He leaned over and kissed her.
