Of course Spike would have his day off ruined by needing to babysit the Cake Twins. He hoped he could bring a comic or something to occupy his time. "Oh no you don't." Huffed Twilight right before he went out the double doors of the library. "Aw c'mon Twi, I'll be good with them I promise. I just wanted t-" "I know you just wanted to relax and read, but Mrs. Cake is counting on us. We need to give our best for her and the Twins." Spike rolled his eyes. "You mean 'me'." "What was that?" "N-nothing, nothing I'm going!" With a sigh he entered the bakery comic-less. "This'll be a great day..." he'd whine, elicting a cute whimper while making his way upstairs to the nursery. There was a small hallway with multiple closed doors; one decorated with stickers surely of Pinkie's doing. A small table had a note with read in bold. "Spike, the Twins are easy to handle since we had Pumpkin's magic reduced so do not worry. If they get hungry there are milk bottles in the fridge downstairs. Just keep the Twins company and try to enjoy yourself. Thank you again dear!" He just huffed. "I reeeaally hope you're right about that Mrs. Cake..." Hours passed while he stayed with the two foals. Luckily for him Mrs. Cake had not been lying, Pumpkin was far less active magically compared to a few months ago when they had her. The most threatening thing she was able to achieve was levitate her teddy bear slightly above her covers. Once the Twins began occupying themselves by light slapping, Spike took a break to look around. He noticed something strange-looking and pink on the dresser next to the crib. He cocked his head and picked up the empty box that was next to it; showing a mare and her foal along with the device. "A... breast pump? The heck..." he'd mutter, reading the details with a keen eye to get every last bit of information. He curiously picked up one of the individual pumps, both of which were a single unit by themselves. "Sooo this would go... oh wow..." he couldn't help but blush at realizing that the large funnels have touched the mother mare's teats. He inspected each part, taking note of the size of the funnel by putting his hand over it; barely able to reach top and bottom with his claws. He was confident that it could cover a good part of his face if he put it on. The more he thought about it the more turned on he became; his light pink penis now sliding out along with his hefty balls from his slit. The Twins both looked over at him in curiosity and at that twitchy pink thing. With a smile the little dragon grabbed the manual. He read the basic functions and tried to turn it on by one of the buttons on the top but it did nothing. "Oh... 'bottle must be attached', duh..." He'd snort and put the pump on the dresser again. "I'd say it's getting close for you guys to eat anyway." With some cheeky whistling and his wobbling genitallia he made his way down to the kitchen and opened the fridge. At least twenty modest-sized baby bottles full of milk were there, nipples already attached. He took three and made his way back upstairs, the cold really getting to his chest while holding them against his body. Both foals brightly smiled and cooed in joy at seeing the full bottles enter the room. "Alright, dinner time." He'd smile and hand them each a bottle which they promptly began raising and suckling on; already self-sufficient in feeding themselves. Seeing them suckle made his rod bounce, though he didn't know why. Smiling, he unscrewed the nipple to the extra bottle he had and screwed it on to the pump. Now he pressed the button firmly. *Vrt, vrt, vrt, vrt, vrt...* The pump buzzed in rhythm. He could see something moving behind the plastic with each cycle. "Weird..." he'd grin, more fascinated with this thing than most males should be. Curiously he put his hand over it. Nothing. Then he tried it on his belly. *Vrrrrt, vrrrrt, vrrrrt...* The funnel could be seen tightening slightly around his skin as a portion of his belly began lifting towards the open hole before retracting back to normal. Spike began chuckling at the strange sight. "This is kinda cool!" He'd proclaim to himself aloud, causing the Twins to stop a moment to cock their heads before minding their bottles. The dragon kept the pump steady while the bottle of milk sloshed underneath. It definitely added weight to the pump which already had a nice heft. He had eventually sat down in a chair tucked nicely in a corner of the room with the pump and manual. With further curiosity he tried it on his chest and became fascinated with the flesh that it comfortably pumped; trying it on various strengths that the manual recommended and playing with the settings. His eyes scanned between his flesh being comfortably stretched to the screen on the top of the pump motor where his claw conveniently reached; clicking on different cycle rhythms along with suction power, though he only made it to the fifth setting before it became uncomfortable. Sighing, he pulled the pump away from his flesh as it came off with a pop, leaving a nice hicky on the left side of his chest where it sucked. Now his penis began to ache. A wad of clear pre glistened in the sunlight that entered the window. "Ngh... dammit not now..." he'd grunt in frustration, holding the base firmly as pre spat out of his rod to relieve some pressure. He did everything in his willpower not to masturbate; not wanting the foals to see him or to make a mess. He had enough to clean with their diaper changes. Then his curiosity hit him like a ton of bricks. He looked at the pump in a new way and a cheeky smile crossed his lips. The hole looked large enough... and his cock had some girth to plug it; maybe it would work. Curiously he held the pump firmly in his grip along with the base of his cock and guided the two together. *Vrt, vrt, vrt...* His tip pressed against the hole as his heart skipped a beat. *Vrrrrt, vrrrrt, vrrrrt* "N-ngh..." he'd quickly tilt his head to see the flesh inside. It felt strange, not satisfying compared to his chest or belly and only parts of his cock tip seemed to engorge forwards. He whined in worry that this wouldn't work even though it should. While looking around he noticed a bottle of lotion which he quickly reached for after taking the pump off of his meat. After a few pumps he lathered his rod up from base to tip, hearing the satisfying squelching sounds of the cream between his hand and cock. "C'mon... please work..." He'd beg after wiping his hands on an unused diaper. With a sigh he braced himself and took his meat in his hand while guiding the pump again to his tip. *Vrt, vrt... SHLMPH... vrrrrrt... vrrrrt... vrrrrt...* "Awww yeah..." Now his view of the funnel was full of his cock being sucked and released by the strong, rhythmic suction. The tip was being pulled back and forth just like his belly and chest flesh was before. It looked like it should have hurt but it didn't. The tightness inside along with the firm seal that the pump gave felt more like a massage to his penis than pure suction. With a smile he spread his legs wide and let it work, holding it steady in place to prevent the weight of the milk bottle from dragging it off. He experiemented with the settings like he did before, setting it from the default one all the way to eight; the maximum being ten as the manual indicated. His favorite had to be the cycle settings from stimulation to milk flow, each with their own button on the pump to mix and match the suction power. He could feel a pressure in his groin, far stronger than usual when he had to orgasm. He braced himself and leaned to the edge of his chair, getting a good grip on the pump and quickly clicking the milk flow suction cycle as it gave longer pumps. "A-aah, AHHH!!" He'd yell out as he came. His tip nearly touched the base of the pump's plastic from being drawn in so deeply; his cum instead shooting against it and washing over the head before sliding down into the contracting flange that allowed fluid passage into the bottle. He could hear his semen splash into the milk below, contaminating it and turning the pure white fluid into a slight off-white with small clumps breaking off into the milk as it floated around. He couldn't help but pant and squirm in his seat; his body screaming at him to remove the pump and stroke himself off to a full orgasm instead. It just felt too good; too unique compared to his hand. He could feel a rush of sensation engulfing his tip from overstimulation, but he couldn't bare taking it off just yet. He whined and moaned deeply as it nursed on his still engorged member. The little dragon could feel the ache in his groin increasing, causing enough discomfort for him to rub and knead at it in hopes of relief. Then it happened, his cock began to tense hard and his body shivered in ecstacy once again. "A-ahhh! O-oh my fucking CELESTIA!" He'd shout, unintentionally scaring the Twins as they cried while he was pumped for another heavy load of semen; unable to care for or coax them in the moment. The overwhelming sensation caused his cock slit to feel itchy and his taint and groin to cramp with each pump of semen; being far more congealed than before, but it still found its way into the bottle with relative ease. It was as if his entire reproductive system was being sucked. He was forced to his feet as he stood there in the middle of the room, one hand now stroking the base of his throbbing meat to try and drain himself of every drop. It took a full minute before he felt the contractions fade despite his cock still hard as a rock. *SHLP* He slid his rod out of the hole wetly. Spike's body shook as he turned the whirring pump off, leaving the room silent aside from crying foals that needed attention. "H-hold on guys..." he'd pant, holding his chest a moment. His heartbeat never felt so strong before. Quickly he unscrewed the bottle and put the nipple back on before taking it downstairs to the fridge. He would deal with it later, but right now the Twins needed comfort. After wiping his hands on his legs he made his way back to the foals; burping and comforting them as best he knew how. With the sun setting, it was now Twilight's turn to take the night shift and for him to finally get some rest.
