Two female scientists are working on a new form of power source. One scientist has an hour glass figure and huge tits, she also has a large cock amongst other things due to her own research. She has blonde hair in a pony tail and brown eyes. She is wearing an open lab coat. The other scientist has red hair and green eyes. She is extremely muscular with enormous round tits and six pack abs all from her research. She is taller than the blonde scientist to the point the blonde is at heart height. The blonde said ready? She places her hand on the red head’s chest. The red head said I am eager for this. The blonde straps the red head to a table. Then she gets a saw and cuts her chest open the red head moans. Inside was a massive heart. The blonde said now time to get as much as we can from it. The blonde gets the machine ready. There are four tubes that will connect to a different chamber of the heart. One will drain heat, another will drain the electrical signals, one will drain kinetic energy, and the last one is sound powered. Of course all of these had to pierce her heart to be effective giving the read head multiple organs. The blonde said I need to get it to pump more. The red head smiled. The blonde started licking the red head’s pussy making her heart beat with more force. The red head orgasmed and the blonde drank the fluids, she noticed a second none pussy juice fluid there. The blonde said had to piss? The red head why bother holding it in. The blonde smiled and said let me share. The blonde crawled on top of the red head’s muscular chest and above her exposed heart. The two started French kissing. The red head enjoyed her own taste as much as the blonde did. The blonde said now I will need a drink of a sweeter variety. She started sucking the red head’s tit drinking milk from it. She then pushed the red head’s other so she can suck on that one. The blonde then suck her own giant milk giving tit and gave the other to the red head, it is better to share after all. The blonde said you should have a meal since your heart is working so hard. The blonde shoved her huge cock in the red head’s mouth and she deeptrhoated it. The blonde cummed in her, then she felt like giving her a drink. The red head sucked the piss out of the blond’s cock making her cum again. The blonde said now to over work that thing. The blonde started fucking the red head’s pussy. She was also over working her heart as it was beating to fast. The blonde knew she can’t stop. The giant heart burst but even in that state it continued to beat. The red head broke her restraints. She then used her strength to open the blonde chest exposing her own beating heart. It was a semi robotic heart. The red head ripped it out giving the blonde an orgasm. The heart was still attached due to some arteries. The blonde said so do you want to stab it, crush it, eat it, rip it out completely, or fuck it. The red head gave her answer as one finger stabbed the blonde’s heart making her moan with pleasure which only increased as the red head slowly squeezed it before it got crushed. The red head bit it before ripping it out giving the blonde a tremendous orgasm making her milky tits leak. The blonde said thanks for the gift. Both of their hearts were regenerating as they always do so they can do this again. The blonde said great you heart is still powering it. The red head said and remember we will be testing these on your heart. The blonde said of course but first how about I feed it directly, I have some fluids from this cock I can share. The red head thrusted her muscular chest forward exposing her heart even more making it easy for the blonde to plunge her cock into that giant heart. They both already know each other’s hearts are great sex toys, but right now they are seeing how much power they can make. Before they switched roles they cummed together. Pussy juice, cum, milk, ans piss was released during orgasm, and blood from their burst hearts leaked as well. They then switched positions.
