"It was a delivery like any other delivery, Amy and Leela was to deliver 2 big creates to another planet, pretty light ones indeed, but as they landed they got surrounded by guards, "Of course, never goes easy when I have to deliver" Leela sighed, "Go on what do you want" she sighed at the guards as they cuffed them both, "You have been requested by the lab" the guard laughed as both of them got carried away as they struggled but as they where outnumbered they where thrown into the cell with ease.

"Oh god Leela what am I gonna do, Kif will be worried" Amy started to panic pacing back and fourth in the cell, just as the room door opened a 7-foot alien bent through the door, skinny and had long brown hair, wore a lab coat and hat a bat like appearance, "So you must be Leela and Amy from Planet Express" he chuckled "Sorry my guards where a bit rough but it had to be-" he got cut off by an angry Leela, "I swear to god if you don't let us out I will shove my foot so deep down your throat it will come out of your ass" she demanded, "Woah woah, chill, you still have one more task before you go, clearly you did not read the contract, I paid double for two test subjects for an experiment then you are free to leave, it was signed by one errr... Bender, Leader of Planet Express" the scientist rubbed his chin, " Oh of course he would be the one to sign it, fine, we signed a contract what do you" Amy then interrupted Leela "Are you serious Leela, I just want to go home" Amy complained, "Yes we will keep to our contract Amy, so what do you want us to do" Leela yet again sighed.

"Well these boxes are for you, put on what is inside and come into the main testing station" the scientist chuckled leaving the room and the Cell doors opened. 15 minutes had passed and they walked out in cute tops and super thick diapers, "Really feels like I'm auditioning for the New Years Baby" Leela facepalmed, "Well I change my mind, I think this attire is super cute, and hey the diaper could totally be a cushion too" Amy laughed, "Right I want you two to get under the pipes and open up your diapers, it's a totally safe experiment we are just testing the absorbency" the scientist chuckled, "Fine" they nodded at each other and opened up the diapers under the pipes.

"Well perfect let it begin" he grinned pressing a red button freezing them in place as the hot sticky cum came from the valve, as soon as it hit their skin their minds began to feel fuzzy, Leela was angry "You betrayed us" she shouted but the Scientist replied sharply "No I didn't, I didn't say what it testing the absorbency of, what we are testing is the absorbency of a certain aliens cum, it lowers the IQ of whomever it touches" he laughed, "Errg my head Leelee my head hurty" Amy was hit by the effects fast as she couldn't move the diaper was filling fast her panic started to turn to a blissful look, "Maybe not bad....Mnnnn~ C...Cummies feel good" Amy murmered, "No Amy you.... you got to stay strong" Leela was struggling against the effects, "So girls, how do you feel now?" the scientist questioned, "Me love Cummies, So big and sticky, need more, no need to think" Amy blissfully replied, her mind now zapped of free thoughts, she was just a dumb cum addicted diaper slut, "Yes very Good" he chuckled, "Now how about you Leela" he smugly asked looking at her expression that she was about to break like Amy, "Ohhh Fuck, I don't want it to stop, my mind is melting just like Amy" her mind finally broke, she wanted more of the empty mind, it felt so good to be drenched in a thick soggy cum diaper, all her will to fight was stripped away with her IQ, she wanted to stay, "Yes wonderful, what do you now say Leela" he chuckled again, "Cummies make Leela happy and dummy" she started to chuckle, her mind lost in the bliss, "Good" he laughed pressing the red button making them drop to the floor under the weight of the diaper, they just sat there rubbing them like a pregnant woman would her stomach, the scientist wrote down the results and picked up the phone "Can I please have subject 2 and 3 taken to the nursery, I want to examine long exposure to the substance, thank you" he put down the phone and walked over to the observation bay, finally his experiment worked"
