After Jeff finished masturbating in the bathroom, he cleaned himself off, and returned to his room . It was difficult hiding his penis now that it was 6 inches longer. His custom underwear no longer fit, so he had to find a baggy shirt to cover anything that might be sticking out.
She must have not activated the alter reality button, he thought. Thank god. Who knows what other weird changes it might have caused in reality. This is just getting too freaky. As soon as she leaves, I'm changing everything back to normal.
Jeff was surprised when he saw Elizabeth sitting in his chair in front of the computer. "Hey, what are you doing?"
She turned the chair, looked up at him and smiled. "Oh good, you're here. Now we can begin, " she said, as she hit enter on the computer keyboard.
"I thought I told you to leave that alone, " said Jeff nervously. He tried to look around her, to see what she had changed, but she stood up and blocked his view. She was shorter than him, just around 5'5", but because she was directly in front of the screen, she completely obstructed his view.
Elizabeth shook one finger back and forth, like parent scolding a child, and clicked her tongue. "Tsk, tsk. Jeff you have been a bad, bad boy." , she said.
Jeff felt his balls begin to change. They were enlarging, and slowing filling with a massive amount of seed. "It's not what you think. I can explain. Just let me see the computer and fix what it did."
Elizabeth laughed. "Oh no, Jeff, I'm not mad about you using the computer program on yourself. The changes you made were good, very good, in fact. No, I'm just upset because you didn't share, "she said with a smile
He was suddenly very aroused, and he felt his penis growing once again. He was beginning to feel light-headed, as blood started to rush into his rabidly engorging penis.
Elizabeth rushed to his side, and grabbed his arm. "Oh, dear, you look dizzy. Here let's get you over to the bed so you can lie down." She gently guided him to the bed, and laid him flat on his back. She pulled his shirt off of his chest, and looked down at his pants. His penis poked out of his underwear.
"That looks uncomfortable, let me help, " she said, as she pulled down his shorts roughly.
Jeff protested weakly. His was so horny it was hard to think. "What ... What are you doing?"
Elizabeth started massaging his cock with her hands. "Something I've wanted to do for a long time. Something I think you've really wanted to do, too."
She took off her shirt, and revealing her soft large breasts, and began to rub his cock between them. She was rewarded with a few dribbles of pre-cum, which she eagerly licked up. She jumped on the bed and straddled him. "Yeah, baby, that's what I want. Just give me some more. " She turned and presented her cunt to his face, and began to run her tongue across the top of his shaft, dipping it inside and out of his urethra.
Jeff began to relax and enjoy it. What's so wrong with this? he thought. If Liz isn't disgusted by my horse cock, why not? It's better than fucking some horse!
He began to lick her cunt, running his tongue, along her clit. Elizabeth moaned softly, and began to attack his cock more furiously, licking the tip of his cock with her tongue, and rubbing his shaft with her hands. As she licked, Jeff noticed her tongue felt different - not unpleasant, but longer and little rougher. He looked at her thighs resting on his chest, and saw that they, too appeared different. Thicker, and covered by thin short soft red hair. Finally he looked at her face, and saw that her nose was wider, with flared nostrils that seemed to end near her lips.
"Stop, " he said weakly. "We have to stop, something's wrong."
"No, said Elizabeth. "No, this is what I want. We can't stop. I'm so close." She began to accelerate her pace, rapidly alternating between rubbing her breasts and hands up and down his shaft.
Jeff tried to sit up, but Elizabeth felt heavier than he remembered. He began to shove her in the back, trying to dislodge her from his chest, first softly, then with more force. She responded by wrapping her arms tightly around his shaft, hugging it and refusing to be moved. She placed her mouth and the tip of his cock and began to suck forcefully. Jeff tried with all his might to keep from cumming, but the sensations were overwhelming. After a few seconds of token resistance, he released his seed. Elizabeth tried to swallow as much as she could. What she missed, she began to lick up eagerly off of Jeff's body. When she was satisfied she had taken it all in, she stood up, and walked over to her shirt, quickly putting it back on with a smile on her face.
"That was nice start, " she said with a smile.
Jeff's erection was slowly receding, and he sat up with renewed strength. "What did you do, Liz? What kind of changes did you put in that program?"
Elizabeth smiled, like the cat that ate the canary. "Well, since there's nothing you can do about it now, I might as well tell you. I've always fantasized about being penetrated by a horse cock, but I couldn't for obvious reasons, " she said, pointing to her crotch. "I'm just too small down there. Believe me, I tried, " she said with no hint of embarrassment. "I had hoped we would hook up. I mean, you still couldn't have penetrated me, but we still could have had some fun...like we just did."
Elizabeth smiled coyly, but Jeff just glared at her. "Go on, " he said, with no hint of amusement. "What did you change?"
"Anyway, when I saw that program, I saw my chance. I wanted to change my pussy to be big enough for a cock like yours. I couldn't figure out how to change the user or subject of the transformation, so I had to figure out a way to get your body to change me. Then I saw the DNA transfer function, and decided to transfer your horse DNA into my body. Through your cum. Then I would have a genetically horse pussy, and it wouldn't be a problem anymore."
Jeff was in shock. He had no idea what effect this would have - on the both of them. "What settings did you use? What were the exact values?"
Elizabeth looked perturbed, and a little uncomfortable. "I don't know exactly. What difference does it make? If I get a little more horse DNA than I expected, so what? I mean, I know some people think your sister is ugly, but I think she's beautiful. I'm kind of jealous..."
Elizabeth suddenly turned pale, and got a strange look on her face. "Whoa, that feels a little weird." She buckled a little and leaned against the wall for support. "I don't feel so good. I think something's wrong."
Jeff quickly ran to the computer to see what Elizabeth had done.
