Allison looks around inside the playpen, and look at her toys she can play in here. She decided to keep the door unlocked since she was the only person here, and Allison would prefer not to be in fear of being locked in a playpen. Allison picks up her dolls in her hand, and was looking at them dumbfounded. She pulled out the time on her phone to see it was barely in the noon time, so after putting it back in her chest pocket, Allison wondered if she really was in the mood for 'TOYYYS' like she childishly yelled. But as she doubted herself, sucking on her pacifier still kept in her mouth, and looked at the dolls held on her hands, Allison's mind made a simple imagination of the dolls being rivals. Suddenly intrigued, Allison started making them punch each other, and started to play with the dolls. What she wouldn't have known is that this would lead her into her imaginary fun for a few hours, starting with the making of her dolls punch and then changing them to befriend and fight a couple stuffed animals lying around before going to the wooden toys and start making words and move pieces around a wooden painted board.
After the few hours of Allison's imagination going wild with her toys, she suddenly stops herself, with a feeling of her bladder being full from the baby milk she drank earlier. With no hesitation, Allison simply lets go of her bladder, which felt easier to go for her than before when she would make herself use her diapers. After filling up her diaper quite a bit, Allison starts feeling horny again, as indicated by her two slightly noticeable points going through her overalls. She looks at the horse rocker with the cord that is plugged in, and thinks about dry humping herself as she rocks on the horse rocker for pleasure. As she now crawls over to the horse rocker, she sees two things that makes it different. One, some handcuffs on the handle and the ends of the saddle, and two a switch on the back of the horse, behind the tail. Allison sits on the horse rocker, and starts rocking while humping the front of the saddle, making her start to make slight moans and drop her pacifier from her mouth. Allison was certainly getting somewhere, but it was going to take some time. As she was thinking about this during her mostly sexual thoughts, Allison's leg just unintentionally kicked up the switch. Allison thought the switch would just play some horse sounds through speakers she couldn't have seen, which would have killed the mood a little bit, but she would be in quite surprised, as the horse started to vibrate in a nice, tingly way. This made Allison even wetter, with perkier breasts, and she started enjoying her horse rocker even more. After some more time, with the vibration and her really squishy diaper, Allison got into a state of orgasm, and came inside her diaper a few times, before getting off the horse rocker. Still within short breaths, along with the feeling the nice tingle after effect all over herself, Allison crawls over to the switch and turns it off.
Feeling super fatigued, Allison was about to grab her throw blanket and sleep in the playpen, before hearing a new notification through her chest pocket, and feeling a little vibration. The notification sound was her Mom saying in a playful tone, "Allieee," which made Allison blush before turning on her phone to see the notification. It was a new text message from her Mama, reading, "Alright Baby, it's about time for your afternoon nap, go sleep back in your crib for me. Can't deal with a cranky teenage baby!" Allison blushed even harder after reading her text, and with the little amount of energy she has within her, she starts crawling back upstairs into her bedroom. As she got in her bedroom, Allison crawls up to her crib, enjoying the softness she feels on her hands and knees, and slowly pulls the polls up to where the lock was activated. Now 'locked' with herself and the stuff that is in her crib, Allison gets her throw blanket on her body, pillow on her head, and grabs a nearby stuffed animal to slowly dry hump it until she completely passes out, enjoying the feeling of her still warm magical diaper.
