First drop by Erica

Jo heard the sound of running water and decided to head over to the bathroom. She slowly pushed the door open to discover Erica humming to herself under the running water. Jo smirked, she had always had a thing for her older sister, there was something about her looks, and style and general being that she really liked. So how could she improve upon that? As quietly as possible she stepped into the large bathroom and shut the door behind her. A small snap and the door was locked and the room sound proof, so no worries about how loud they might get. Slowly Jo krept up to the shower. Erica's outline was visible through the curtain. Though she was hot, she wasn't quite on Jo's level, yet. Jo herself thought for a moment and then it clicked. She new exactly what she would do. Jo snaped and waited for the action to start.

Erica always enjoyed long showers on her own. The warm water falling over her breast was such a good feeling. She rubbed up and down, covering herself in soap and then washing it back off. Brushing over her cute little c-cups sent waves of pleasure up her spine and brushing across the lips of her clit even more so. Erica found it hard to resist herself sometimes. She was hot and she knew it. She was also a pervert and she knew it. Half her mind and laptop were constantly full of all kinds of porn, erotica and fetish stuff and Erica loved it. She loved being a secret dirty little whore. Just thinking about it made her horny. She reached down and started toying with her lower lips, while her free hand groped at her tits. She began by circuling her clit, which seemed a bit more pronounced than normal. Erica had heard of female erections, but this seemed bigger than that. Then again whatever it was didn't matter given how nice it felt to play about with it. Her boobs as well seemed a little heavier than normal. Maybe it was just her being tierd. Regardless they were still sensitve as fuck and felt awesome to play with.

Jo, on the otherside of the curtain, was finding it hard not to breakdown into a mess on the floor. The scene infront of her was so hot, and her pussy so wet, it was practically begging to be filled. Jo moaned quietly and snapped again, to make things speed up a little.

Erica kept on circuling her erect clit and continued squeezing her swollen tits. As she did they both grew. The clit poked out, now nearly an inch long and cilindrical with a distinct head. Her tits also grew, they must be double ds at least. Erica could barely thing straight. Images flashed across her mind. Images of sexy studs with foot long cocks and curvy bimbos with tits that could kill. She pictured herself riding a stud and making out with one of those bimbos. All the while she felt more and more horny. Without thinking she had switched from circuling her "clit" to stroking it. As she did, it grew longer and longer, with each stroke. Her titties also swelled, passing e-cup and finally settling at f-cup size. A breeze was enough to send waves of pleasure up and down her entire body. Erica moaned, she had never felt so good in her life! Following this her butt and thighs started expanding, quickly matching her tits and giving her a perfect hourglass and a bouble butt to die for. Her hair also lengthend and turned a dark black reaching to just above her rear. All the while she kept on stroking her lengthening member. By now it had the unmistakable shape of a cock and reached down half of her thighs. But Jo wasn't finished. One more snap and Erica's new cock jumped to it's final form. Knee length and flat headed like that of a horse. Erica the hot sis had become Erica the bombshell horse cock futa! To finish off, Erica's skin grew pale, almost white. Now Jo was happy with her handiwork. Erica was far to horny to have noticed.

With a snap Jo cleared Erica's mind letting her see what had become of her. Erica didn't notice anything. She turned the water of, stepped out of the shower and came face to face with Jo. For a moment she froze, before giving a small yelp of suprise and stammered out: "Who are you! What are you doing in here!?" Jo smiled and Erica realised, "John? What happened? You're so... sexy..." She trailed off staring down at Jo's femme fatale body. "You know, I could say the same to you!" Jo replied turning Erica to face the floor to cieling mirror. Erica gasped when she saw her reflection. Then she looked down and gasped again. She raised a hand and poked her right tit. It moved. It also caused a stir futher down. Erica gave a little eek when she saw her equine member in its black sheath. She gasped again as she reached down and touched it. Jo was enjoying this, but decided to take things a step further. "This is probably a lot to take in, but basically this is real, not a dream and you are now a horsecock futa. Don't lie, I know you've always dreamed about it, so how about we give it a try?" This caused Erica to blush, think for a moment and then agree.

Jo reached down and grasped her sisters new equine cock. Instantly it stirred and started to harden. Soon the head poked out of the sheath and Erica let out a low moan. Jo started stroking, up and down until Erica was at full mast. Small drops of pre already appeared at the cocks head, and Jo used them to lubricate it. She herself was already wet and could barely wait to drop down on all fours and present her snatch. Once she did Erica wasted no time and placed her hands on her sisters wide hips. She lined up and slowly pushed in. The feeling of Erica's massive horsecock spreading Jo's until now virgin pussy wide open was like nothing Jo had felt before. She let out a cry which turned to a moan as inch after glorious inch of Erica's dick entered her. Soon she was up to the hilt and could enter no further. Jo gasped as she felt it throb inside her. Looking down she could see a large buldge in her stomach. The sight only turned her on more. Erica too was enjoying this, and started slowly pulling out and then pushing back in. Quick on the uptake Jo too started moving and soon both sisters were in a rhythm. Moaning loudly while filling Jo's pussy Erica could only imagine how much fun she would have with this new body! Jo, filled to the brim with delicious horsecock, thought the same. Bit by bit they increased their pace, both moaning loudly with each thrust. It didn't take long for Erica's new internal balls to start churning and her breathing to turn into panting. Jo also felt close. Just a few more and then both screamed out in unison as Jo's snatch squeezed around Erica's cock which started pumping rope after hot sticky rope of cum into her sister. The rode the orgasm together until completly spent they collapsed on top of each over. Erica's cock softened and slid out of Jo's pussy, spilling cum all over the bathroom floor. Both felt amazing.

Jo only just managed to snap her fingers. Instantly the mess dissapeared and both sister recovered. Erica rose fisrt, her semi hard cock swinging with the motion. She gave Jo a hand and pulled her up. "So, care to explain?" She asked. Jo blushed. "Basically, I woke up with this amazing power to change anything with a snap of my fingers, like this" Jo snaped and the hairdryer next to the six morphed into a large pink dildo. "See. So I tried it on me, hence this" Jo gestured down, just as a large drop of cum dripped out of her snatch and onto the floor. "Then I decided to share the gift, and I knew you were a bit of a pervert, hence this" Jo gestured at Erica, just as a drop of cum dripped out of the head of her semi-flacid dick and onto the floor. "Now we just gotta think of what we should do next. Any ideas?" Erica remained silent for a moment, before leaping forward and pulling Jo into a tight embrace. Tits squashed together and dick brushing against snatch she whispered: "Thank you!" How can I ever repay you?" Jo answered: "You don't need to, we're sisters right, why shoulldn't we have this fun together?" Erica couldn't say anything against that.

That only left the small issue of what they would do with the rest of the family...
