Rachel looked at Jasmine and smiled “I think I know how to get back at my sister.”
After they finished cleaning up the bathroom and Rachel’s cock was now a much more manageable 2ft soft cock and Jasmine’s were safely tucked back under her skirt, they crept down the hall to Abby’s room were Rachel opened the door a crack and looked in her sister’s room.
Abby was on her phone probably checking social media or some bullshit and as they watched she got up and started to take a hot selfie of herself. Rachel decided now was as good as ever to act so she concentrated on what she wanted to have happen to her sister and watched in awe at what happened.
Abby was just about to flop back onto her bed when she felt her tongue start to tingle, then it started to swell and lengthen. Before she had time to wonder what was happening a horsecock pushed it’s way out of her mouth and grew down past her chin getting longer and longer! She turned toward the full length mirror and looked in horror at the girl in the reflection with a massive horsecock protruding from her mouth and growing longer down her body reaching past her tits, then her abs, reaching all the way to her waist almost between her legs. The massive horsecock that was her tongue had to be at least 3ft long and it was completely soft!
Rachel looked at her sister amazed and aroused by the huge tongue cock she had given her sister. Jasmine asked “What did you do to her?”
“Well I figured having a cock for a tongue would teach her what a dick truly is.” Rachel replied simply, then explained further. “I gave her a 3ft long horsecock tongue that she can retract completely into her throat when soft and use just like a regular tongue to eat, taste, talk, etc. but I also made her tits into her balls, so to speak. Her tits hold and produce her cum and can stretch and enlarge if she doesn’t cum enough to empty them regularly. I also added a bonus for just you and me. If either of us says her name her cock will get hard and grow an extra foot and she has to cum to go soft but her cock will retain the added length for a day, basically until she goes to sleep.”
“Holy shit!” Jasmine said in a low whisper “And you did that in like the space of a minute!”
Rachel just smiled and softly whispered “Watch this...Abby”
Abby was reeling trying to understand what just happened and why a huge horse dick was sticking out of her face when she felt it a tingle in her cock that quickly started to intensify and her dick started to grow again! Though this time it felt different she could feel her cock filling up, getting hard, picking itself up to stick straight out of her face as it,grew longer still! Finally her cock seemed to stop at twice the length it had been making it 6ft long then it shuddered and grew another foot where it started to leak a huge stream on pre as she finally felt the huge weight on her chest. She looked down and her eyes grew wide her previously perfect D cup tits were now huge looking to be at least a K cup or larger though they did retain their perfect teardrop shape making them look like huge implants on her slim frame. But her cock quickly drew back her attention as it throbbed madly and Abby found her hands reaching up to stroke the length making her moan as she finally started to pleasure herself. She jerked the first few feet of cock, that was all she could reach, and her pre started to spurt out like she was cumming making splashing sounds as a huge pool of pre formed on Abby’s carpeted floor, but she didn’t care as her cock demanded the attention she gave it. Abby could feel the orgasm build slowly and get bigger the longer she took to get there as she couldn’t reach the more sensitive head she had to settle for the long slow build up and she started to whimper as she desperately stroked herself trying to cum. Finally her orgasm hit her and her cock bucked and throbbed shooting huge streams of cum all over her room, blasting minute long streams of cum across every surface in her room. Abby came and came filling her room at a steady pace as her orgasm refused to quit. For Abby this was the most intense orgasm she had ever experienced in her life and was paralyzed by pleasure as she felt new muscles contract in her throat and felt her tits empty themselves of their cum. Finally after almost 15 minutes Abby finally stopped and passed out on her bed, her room filled to just below her bed with cum.
Rachel banished the cum with a thought and looked over at Jasmine “Holy fuck! That was the hottest thing I’ve ever seen! Should we do something else or just call it a night?” She asked her friend then she added “If you have any ideas I can give you the ring and you can surprise me.”
