Start to change your grandfather-Ropes first

Throughout the morning, with the rest of your girls getting their dosages, you continued to monitor your grandfather who was tied up and hanging suspended from the ceiling, his hands roped behind his back and his legs splayed open. He had awoken a few hours ago but the ball gag in his mouth kept you from hearing anything other than muffled screams and even then, you weren't sure whether that was from the sensation of having a giant catheter shoved up his pussy or the fact that there were nipple clamps on his very sensitive nipples.

For added stimulation, to both make his body absorb the first dosage of medicine faster as well as introduce the changes, you had slipped into him a vibrating applicator as well as a clit clamp, the clamp having a vibrating function as well. The moment you slipped it in and turned it on, your grandfather's body went rigid as he instantly came from the sensations. Within minutes, he was coming and moaning, the restraints binding him to the planking position only seemed to heighten the desire to move and the sexual exhilaration he was receiving at the same time. The more he orgasmed, though, the more rapidly the medicine would take effect. As you mentioned to Sam before she left, the man's undoing was his own pleasure and delight. Sadistic, perhaps, but fitting.

Oh so fitting.

By about noon, after Monica and your mother came back from shopping, you were settling down with a book at the foot of the bed and looked at the otherwise young woman in the room with you. He was passed out, hair dripping from the sweat pouring off his body, and the silent hum of the vibrator told you plenty. Slowly, you reached over to the tablet next to your hand and opened the control screen. A few swipes led you to the schematic readout of the medicine, noting that his body had absorbed the full dosage with a 94% absorption rate, much higher than you would've imagined possible, though you suspected that the fact he kept coming and squirting (your grandfather had turned into quite the squirter), that had something to do with the 6%. The room definitely bore witness to his squirting prowess, for sure certain that the aroma of lavender infused feminine lube would never get out from any of the surfaces.

You slipped out of the chair and moved to stand in front of him, deciding to test how things were going by removing the ball gag slowly from his mouth, noticing how much spit and saliva trailer from the red ball portion, and then you tapped a button to start the wakeup rhythm, designed specially by the boys in the R& D department for this particular purpose: keeping a woman awake by stimulation. As you thought earlier, those closet Otaku-freaks needed to get laid. By their mothers.

The stimulation started up again and, though he was exhausted and somewhat asleep, his body was already starting to react to the vibrations going on. For added measure, you had stripped off your pants and trousers and brushed the top portion of your newly enlarged cock against his face. The sheer amount of pheromones and your male scent, coupled with the unsatiated need driven to **** heights by the restraints and the hours-long orgasming, caused a very unnatural feminine moan and panting coming from his lips. His lips parted, though they were a bit dry from the looks of things, and he was surely looking around, thought he blindfold had kept him from seeing exactly where you were. Even the earphones pumping in subliminal messages directly into his ears kept up the appearance of someone in **** straits, just like how you wanted him to start off.

"There's my little bitch," you whispered, almost mockingly in tenderness, as you took the tip of your cock and pressed it against his lips. Your grandfather happily and hungrily scooted as much as he could, which wasn't much, until his lips wrapped around your head and he began to bob as much as he could. You turned up the pressure coming from the vibration to match his movements and soon he was slurping and moaning at the same time. How this was possible with your cock in his smaller mouth was beyond you but somehow, the feminized man did it.

His attention was solely on your cock while you turned and motioned to the person opening the door and immediately slid in next to you. Monica wrapped her arms around you and kissed you, feeling herself becoming more and more turned on by the sights of submissive men, already feminized to the point of being unrecognizable, being permanently transformed into your cumslaves. Kinky perversion powerplay, she had mused. You couldn't help but notice how wet she had become, the flush on her chest, or the way her nipples became very much erect and very stiff to the touch. Monica undid her bra, letting it fall to the floor, moments before you brought your lips to her nipple and sucked on it, causing her to moan and press herself against you. "Finish with this bitch quickly, baby, I need you badly," she whispered and you brought your mouth back up and kissed her.
