I'm pretty sure this belongs in the "writer's lair" and not the main "story time" forum, but the last reply there was way back in November. I know it's selfish of me to put it here instead of there hoping it'll collect more eyeballs this way, but I couldn't find any rules that the main forum was only for stories that are actually written.
Basically, I've gotten tired of reading about one-dimensional characters in unrealistic fantasy scenarios that climax on the second page. Sure there are a lot of good writers on this forum with a lot of good material, but as with any other niche fetish-inspired genre, there's still a lot of uncharted territory in terms of character development. I've begun collecting a list of ideas I'd like to explore in a story I want to write, but I don't think I have much time to write out the whole story any time soon. I'd like to put these ideas out there either so that I could get some advice and some feedback that would help me move forward or so that someone else can borrow some of these ideas and incorporate them into his or her own writing. As of my posting these things, everything is up for grabs.
The first thing I want to incorporate into my story is how to tell a vanilla person you're into adult diapers and ageplay. What has worked for me in the past has been introducing the scene bit by bit focusing on one babyish item or act at a time. For example, I usually start by telling someone I own an adult sized pacifier. It's a security blanket type thing. I had a lot of trouble falling asleep when I was growing up. My mind would always be racing and wandering. The pacifier would draw my attention from other things and relax me, making me feel safe and secure. If the person reacts negatively then I can respond with "It helps me sleep some times, but I don't need it to sleep. I'm not dependent on it." and they don't have to hear about anything else. Nothing that would completely shatter the image of the grown up person they interact with. If the person instead responds favorably, I can go further. I own a baby bottle as well. It takes so much energy and concentration to get anything to come out of it. By the time I've suckled the last drop, all of my worries from the day have faded away. Then I can talk about how ideal it would be to not have any responsibilities, to have someone else look after you and love you unconditionally, and to feel safe and warm and content. Acting like a little kid some times and playing with baby stuff some times makes me feel these things. It's just something I do behind closed doors to take the edge off the day. I don't usually mention anything about diapers unless I'm in a relationship or pursuing a relationship with the person. For me, diapers are sometimes relaxing like other baby stuff but almost always arousing unlike other baby stuff. For this reason, the topic doesn't really come up unless I'm discussing sex with a potential partner.
The second thing I wanted to incorporate into my story is how ageplay can be either arousing or relaxing or playful for me and my partner. For example, when my mommy changes me, sometimes she'll play with my boy parts a little before taping my diaper on. And instead of putting my shorts back on right away, she'll lay on top of me and make out with me a little while groping me or rubbing me through my diaper. And finally after a little more teasing back and forth with some changes in position, the tapes come off and that's that. Other times, diaper changes are very mild. Mommy will give me Mr. Bear so I'm not staring at her and have something to do with my hands as well. The shorts go on right away after the diaper and then mommy lays down so I can cuddle against and on top of her as we get settled in for bedtime. The simple act of me sucking on her breasts can go both ways as well. Some times I'll go real slow with my lips pressed gently against her, using just my tongue to pull her nipple into my mouth. We'll both have our eyes closed, and then after a long while of the same slow movement, we'll both feel super relaxed and close to each other. Other times, I'll suck a little harder. I won't bite, but I'll push a bit chunk of her breast into my upper teeth with my tongue. And I'll wrap my hand around her breast, groping her slowly but firmly with the same rhythm as my tongue. Then unless mommy stops it early, it spirals downhill from there.
The last thing I can think of right now is the fear of ageplay completely taking over a relationship. Because the ageplay stuff isn't limited to sex, it becomes something I want all or most of the time. When I'm on the phone with my girlfriend, my default setting is to call her mommy and talk like a toddler (nearly no actual baby talk but just a little kid sounding "accent" with some mispronunciations and over-simplified grammar.) And it's completely different from how we interacted when we first stated dating, what she thought she was getting into. Where's the confident, smooth-talking romantic she signed on for? It's late now, and I forgot what else I wanted to say about this topic. But I definitely want to write about this sort of conflict.
