r/distension is 519K members who love watching girls get stretched to their limits. Huge toys, massive cocks, fisting, and anything that makes a girl's holes visibly bulge, stretch, and gape. You can see the outline of the toy through her stomach, or watch her pussy stretch around something way too big. It's extreme and not for everyone, but if watching tight holes accommodate impossibly large objects gets you going, this niche community delivers content you won't easily find elsewhere.
