>wife and I have been in chastity for a week ahead of an anniversary. Much Teasing, both on edge as fuck.
>wake up in a dungeon. Strapped to the table. Paci-gag strapped in mouth, legs strapped to stirrups. Wearing pink girly dress, which fluffs out at the waist but nothing below. Chastity belt removed.
>look next to me, wife in same condition. See open diaper under her hips, squirm and feel the same under me.
>corset wearing, latex stocking smoking hot domme walks into our vision. She is holding two shining silver rings about an inch or two wide.
>walks between us, and shows the rings close to our eyes. The outside is a thick groove, lined with tiny vicious looking spikes.
>domme tells us these are going in our asses. Careful not to clench because they'll utterly destroy the muscle if they do.
>destroyed muscle will mean diapers forever. in the most humiliating way, they'll be needed.
>she goes to work fitting them. We both moan and pull our our binds, but no good. Once in, we try not to move at all, for fear of clenching down.
>domme tells us what good babies we are. But there's a little game she wants to play. She stands between us and starts rubbing wife's clit and stroking my cock.
>domme reminds us what happens if we cum - involuntary clenching. diapers forever.
>plays with us faster. More insistently. We both try not to get into it.. but diapers and bondage and kinky, not to mention week of chastity, we're both getting going.
>Domme tells us that we have a choice. She can stop now, and install our chastity belts back on permanently, or we can cum, and it's diapers forever.
>Getting close to the edge. Running out of time to decide. Look over at wife. She looks at me, then closes her eyes. She's cumming.
>pushes me over the edge. Can feel the pain of clenching down on the ring. Strongest orgasm of my life.
>domme tapes up our diapers.
