Michael sat at his computer playing his favourite game with his guild-mates, mostly friends from school. They had just finished their latest grind and finally got the gear they needed for the next boss. It was a beautiful Friday night and being the wild and rambunctious teenager he was, Michael was determined to just stay inside and play video games with his friends. As they neared the boss room, Michael and his guild-mates spoke excitedly about their plans for the evening: stay up late running raids and chugging soda. His mom, however, had other plans.

	He didn't hear her as she approached from behind him; he was totally immersed in his game. His mother trudged angrily toward him and pulled the headset from his head. 

	"You can't just sit inside and play games all the time. You need to get outside or else," she threatened.

	"Or else what? I'm building social skills playing with my friends," Michael argued slyly.

	With a mischievous grin, his mother said, "Well, I'm glad you asked."

--------------------

	"But mom! Why do I have to do it? Couldn't you find someone else?" complained Michael. She had volunteered him to babysit his little sister. His parents would be taking a trip out of town and needed someone to watch the baby for the weekend.

	"This was a last minute decision. We couldn't find anyone else on such short notice. Besides, if you're so concerned about your social skills, maybe it would do you good to learn another skill: babysitting."

	Michael put up a valiant effort, but it was all for naught. As he watched his parents drive down the road, Michael sulked knowing that his weekend plans had been ruined. He turned to see his little sister, a gray wolf like him, playing with her feet on the ugly tan carpet of the living room. She was about a year old and he wasn't too excited to be stuck watching her all weekend. She looked up at him with her pale blue eyes and smiled. Michael wasn't a fan of children, but he did have to admit that his little sister was pretty cute.

	With a sigh, Michael walked into the kitchen. On the counter, his mom had left him some money, enough for him to order pizza. A note next to the paper laid out pretty much everything he needed to know about taking care of his baby sister.

--------------------

	Michael,

		I'm sorry I had to do this and I hope you aren't too angry with me. I just think 	you need to stop sitting around so much and take some responsibility. You're a 	growing boy and I know you'll do just fine. I left some money for food if you don't 	want to warm up the leftovers in the fridge. 

	Make sure to:

		1. Give your sister a bath (watch her carefully!)

		2. Feed her whenever she's hungry

		3. Change her diaper

		4. Go to bed at a decent hour (you and your sister both)

	Love you,

	Mom

	P.S I put parental controls on the router so you can't play that game all weekend

--------------------

	Grimacing, he crumpled the note in his hand. Even when she wasn't home, she still managed to defeat him. Michael composed himself and straightened the note out on the counter. He still had his phone but there was nothing but mobile apps on there and nothing he could play with friends. He shot a quick group text to his buddies letting them know the situation. Within minutes he had a bunch of disheartened replies. His buddy offered to "hack" the router password for him, but Michael declined. Not that his thirteen-year-old friend couldn't do it, well... that too, but mostly because he couldn't imagine what his parents would do if he spent the whole weekend playing games instead of taking care of his sister. He'd be grounded for months.

	Walking back into the living room, Michael plopped down on the couch near his sister. She'd moved on to playing with her favourite toy, a stuffed fox. He ordered a pizza on his phone and sat back to watch some TV. Why this was seen by his parents as an acceptable alternative to the computer, he never knew. I guess they didn't want to come back and find that they had literally bored him to death.

	After a while sitting there engrossed in his show, Michael looked down and saw his sister staring back at him. His attention was broken when the doorbell rang. He walked to the door and paid the delivery guy. He brought the pizza back into the living room and relaxed on the couch. His sister's attention was immediately back on him. She cooed softly and reached out her hand toward the box on the coffee table. 

	"Nope. I'm not your usual babysitter, but I'm pretty sure you're not old enough to eat pizza. I'll go get some nice soft peas for you though."

	Michael grabbed a slice from the box and made his way back to the kitchen. He grabbed a jar of the disgusting mushed peas from the cabinet. It wasn't the first time he'd fed his sister, but everything else he left up to his parents. He was definitely dreading the inevitable diaper change he'd have to perform. Shaking the thought out of his head, Michael finished his slice of pizza and walked back into the living room.

	Over the course of the next 15 minutes, Michael managed to finish off half of the pizza and his sister at most of the jar of peas. When she was done, he picked her up and burped her over his shoulder. A piece of valuable advice his mom forgot to mention was that this was sometimes a messy process. Michael knew what happened as soon as he heard the noise. Sighing, he pulled his sister off his shoulder and looked to see the aftermath. Yep, he definitely needed a change of clothes and a shower. He decided that he might as well kill two birds with one stone and give his baby sister a bath at the same time.

	The bathtub was filled though not as warm as usual. Michael removed the shirt from his sister and said a silent prayer to himself as he began to remove her diaper. It was clean! At least he got to put off that learning experience until later. He started stripping down too, tossing his nasty shirt in the laundry chute and covering himself with a towel. As he removed his socks, it dawned on him that there was really no reason to hide his body from his sister. What was she going to do? Tell on him?

	He slowly lowered both himself and the baby into the tub. She giggled as he sat her in front of him, facing him, between his legs. There was plenty of bath toys for her to play with and she immediately grabbed a toy duck and started splashing. Michael reclined slowly back against the wall but made sure to keep an eye on his sister. He'd read that babies can drown in just an inch of water and he really didn't want to test that claim. Other than the water occasionally splashing him in the face, he did have to admit that it was pretty nice to just relax and unwind. 

	Michael quickly zoned out, just absentmindedly staring at his sister playing. He didn't even notice when the warm water began to have a different effect on him. Beneath the surface of the water, the very tip of his penis began to slowly emerge from his sheath. In fact, he wouldn't have noticed it at all had it not been for his sister grabbing the new red "toy" that had appeared in front of her. Michael let out a confused cry as he lurched back against the wall of the tub. His little sister reacted with surprise as well and looked up at him.

	"I'm sorry! I'm so sorry!" exclaimed Michael. His tip immediately retreated back into his sheath.

	At that point, his confusion and shock with himself were overwhelming. He had just gotten an erection staring at his baby sister. It must have been the water. Or maybe it was just how relaxed he'd felt. Yeah, that was it. He was a teenager going through puberty. This was just something that happens at that age. It had nothing to do with his sister.

	He decided to quickly finish washing up, get his sister changed, and head to bed. When they were both clean, he took his naked sister to her room. He put her down on the changing table and taped a new diaper on her. In his rush, he knocked over the baby powder and made a nice cloud around himself. Michael always loved that smell, but his current mental disarray gave him no time to enjoy to scent.

	While he tried to remain calm on the outside, his mind was still a jumbled mess. He carried his baby sister to her crib. She was practically asleep before her head touched the blankets. He flipped on the baby monitor, turned on her night-light, and made a swift exit. On the way to his room, he grabbed the other part of the baby monitor from his parents' room. Finally back in his room, Michael closed the door and collapsed against it with a sigh. He sat on the carpet and stared at his bed for a long while. Internally, he tried to justify his actions but just couldn't seem to get the bathtub incident out of his mind. Eventually, Michael got up and made his way to his bed, still smelling of baby powder. He would figure this out tomorrow, he was sure of it. He just needed a good night's sleep to clear his head.

	Around two in the morning, he was startled awake by a noise coming from his bedside table. It scared him at first until he realized the source of the noise was the baby monitor. It was his sister crying in the other room. The moment Michael dreaded had come. It was time for a diaper change. With a sigh, he made his way down the hall to her room.

	Sure enough, when he checked her diaper, it was very wet. Thankfully, it wasn't the exact outcome he had feared, but with the events of tonight slowly coming back to him in his sleep-induced delirium, he felt more and more apprehensive.

	Michael lifted the softly crying baby out of her crib and set her on the changing table. Taking a few deep breaths to calm down, he began to undo the tapes of her diaper. He paused briefly while grabbing the last tape. He could do this. He needed to do this.

	He opened the front of her diaper, purposely trying to avoid looking at her by keeping his eyes shut. He blindly felt for the container of baby wipes on the table next to her. He found it and grabbed one out. Reaching down, he tried to clean her without looking but that wasn't going well. Michael braced himself mentally and opened his eyes to look down at his sister. Laying bare, she stared back up at him and cooed softly, no longer crying. He could feel the blush in his cheeks immediately and his heart was racing. He couldn't help but stare. Her little pussy was staring him right in the face and he didn't know what to do. Michael's mind, however, knew exactly what to do. His body began to react as well. 

	Slowly, his tip began to once again emerge from his sheath. This time, however, it didn't stop with just the tip. Michael's cock involuntarily twitched as it grew to near full size, his knot still remaining within the sheath for now. Michael didn't even know what to do. He just couldn't stop himself as he stared at the beautiful baby girl laid out before him.

	His hand reached out, seemingly on its own. It rested softly against her thigh. With a slow but deliberate movement, he moved it so it was just barely touching her little pussy. The little baby giggled again and seemed to enjoy the attention. This was the point of no return for Michael. His body clearly wanted this and, at this point, so did he.

	Michael's throbbing cock pointed the way as he moved closer to the heavenly sight before him. Gently reaching down with the baby wipe, he began to move it slowly across the baby's tiny slit. It felt so soft. Moving downward, he wiped her clean. He made small circular motions over her little pucker. Michael looked up at her when he did that. She smiled back down at him, apparently not minding the attention he was giving that part of her. When she was clean, Michael tossed the wipe next to him on the floor. He'd clean that up later. For now, he had other things in mind. 

	Gently, he moved his finger across his sister's small slit and applied just enough pressure to begin parting her lips. She was so soft and still a bit wet inside from her earlier accident. He moved his finger across the whole slit and noticed her little body shiver when he reached a certain part. Michael would later discover that he had just rubbed his baby sister's clit, but all he knew in the moment was that she appeared to really like when he did that. Carefully, he moved his finger up and down along that particular part of her pussy and watched as she began to writhe and squirm on the table. A little more attention on that spot and suddenly her breathing became shallow and her little body shuddered. 

	Michael stopped his finger motions for fear that he'd hurt her somehow. Quite to the contrary, however, she looked down at him and smiled. Barely able to contain his excitement, Michael smiled back and slid his sister closer to the edge of the table. He could no longer ignore his own needs. His cock dripped clear precum onto the table between her legs. 

	With one hand, he grabbed his cock and pointed it down toward his baby sister. With his other hand, he spread her pussy apart. She looked back at him with those pale blue eyes that made his heart melt. Leaning in, he brought his tip to rest gently against her cute little pussy. Michael's breath came shakily as a slowly pushed forward with deliberate care. Nothing had ever felt so great.

	Since he was only thirteen, Michael wasn't particularly well-endowed. As he pushed forward, his baby sister wiggled and straightened her legs. He continued forward as he watched he face for any discomfort. She didn't seem to mind at all. In fact, Michael had soon bottomed out, his knot resting outside against her tight little pussy. He waited a moment, again looking for signals from his sister. She just looked back at him with those big blue eyes and he knew he was all clear.

	Slowly, Michael withdrew his throbbing cock from the tight confines of his baby sister until just the tip remained inside. Rocking forward once more, he repeated the motions, falling into a slow but steady rhythm. The tiny pussy was wrapped snugly around his cock and glistened in the soft light of the nearby nightlight. Each time he moved his cock in and out, it made an audible squishing noise that only further enraptured him. 

	Breathing raggedly, Michael continued to grind against the tiny girl lying on the table. His precum added the much-needed lubrication for such a tight coupling. His balls began to pull upward as his imminent orgasm approached. The wet diaper beneath his baby sister was dutifully absorbing the extra fluid now leaking down across her anus. He had only discovered masturbation recently, but he knew he was getting close to filling his sister full of his seed.

	A few more thrusts was all it took. With a grunt, Michael gave in to the feelings from the tight pussy surrounding his shaft. His sister smiled down at him as her pussy milked her big brother for everything he had. Michael's cock throbbed over and over again as he began pumping shot after shot of his plentiful wolf seed into the tight pussy of his baby sister. This was easily the longest orgasm he had ever experienced. Filling her inside, his thick cum began to leak out around his shaft. It dripped down the little wolf girl's ass and made a small pool in her used diaper.

	Michael slowly came down from his high and gently removed his cock from the tiny, gaping pussy of his sister. His mark was evident as a globule of cum dribbled out of her. He was considering giving her a bath again after the mess he made, but decided against it. It was late. Instead, he removed the cum-soaked diaper from beneath her and slid a clean one in place. Taping it around her waist, he knew the diaper would absorb any extra cum that leaked out in the night.

	With the new diaper in place and sleep once again overcoming the both of them, he put his sister back into her crib for some well-deserved rest. He kissed her gently on the forehead and headed back to his room. Maybe he didn't mind babysitting so much after all.
