The Classic Runde Butt Plug

Wasn't sure about the round shape at first, but that uniform spherical head fills you out in a way the tapered ones never did for me. The stretch is gradual and comfortable, and cleanup afterward was way easier than I expected.

The spherical head gives such a smooth, even stretch compared to the tapered plugs I've tried, and that fullness actually lasts instead of fading after a minute. Sat comfortably for a good while too.

Wasn't sure a round shape would feel this good, but the spherical head gives a really even stretch and a nice full feeling. It stays put once it's in, and cleanup afterward was easier than I expected.
