Basically, just the process of putting something large into your genitals. Be that dildos, plugs or any other kind of sex toys, or even a large penis / some other kind of object.

Ride of Their Lives by Jole1038 This three-part unbirth story by Jole1038 is again a bit unusual for this author. Sera is a centaur and during sex-ed, she quickly learns what unusual anatomy female centaurs have. Two wombs, one horse-like – one human-like. She gets quite excited and especially when Toby, an under classman, gets interested in centaurs, they begin “exploring” her body together… ...
New Duties by Jole1038 Somewhat of a different story, Jole1038, as it’s all about cum-inflation. The three parts tell of different experiences of different people with their new condition. Men can randomly get a giant erection, which won’t stop, until “they’ve been released” and women seem to have got really stretchy when coming into contact with a man during this phase. It doesn’t take long, until certain women come up with different ideas and plans to enjoy the most of these predicaments… ...
Midnight Mistake by Jole1038 This is probably one of my all-time favourite unbirth stories by Jole1038 ever. This work follows Bethany and her brother Victor and their experiments with unbirthing. Things get quite interesting, once they find an old corset and Victor comes up with the idea of how they could hide Bethany’s giant belly. ...
Making an Ass of Yourself by Jole1038 This four-part unbirth story by Jole1038 follows Lenny and his babysitter, Janet. Lenny gets a bit curious and finds an absolutely giant butt-plug Janet secretly brought with her and when he gives her a tour of the house, he realizes she’s already inserted the giant toy into herself and was walking around with it. During some play sessions, Janet has a little accident and the plug gets pulled in too deep and gets stuck, so she asks Lenny to reach into her and pull it out. But because of Lenny playing around too much, he actually gets his arms quite a bit further in than expected, which brings up an idea for Janet… ...
Petite Problems by Jole1038 Another one of my favourite two-part stories by Jole1038 on DeviantArt. This work follows Tina, who happens to be a bit on the shorter side at 160 cm. Finding out how easy it was for her to insert quite large sex-toys into herself, she started enjoying going larger and larger. She comes up with some interesting ideas, especially when she gets to watch over her 13-month-old cousin for a few weeks. ...
Filled to Fit by Jole1038 Amazing sex-toys story by Jole1038 on DeviantArt. This work follows the female main character discovering what her roommate, Kira, actually does during her masturbation session. Shocked at the size of the toy-eggs Kira easily pushes into herself, she bursts in, surprising Kira, and asks for an explanation. Turns out, Kira was streaming her sessions the entire time, and with her usage of absolutely enormous toys, she has managed to expand her body to the extreme. ...
