經典圓形肛塞：3件式肛門訓練組

Started with the smallest one and honestly the jump to the middle plug felt like a real step up, but in a good way. That round head gives such a full feeling once it's in, and I actually look forward to the stretch now.

The three sizes make progression feel natural instead of intimidating, and the round heads give a full, even stretch. I worked up from the smallest over a couple weeks and the middle one hits the spot nicely.

The spherical head on the middle plug gives a really nice full feeling without being too much for a warm-up. Only thing is the base could be a touch wider for grip, but honestly it's been fine so far.
