Special Sissy Privilege

Since Mistress has taken on Master as a lover, my "conjugal" rights have been severely limited.  Sex with Her is far from what normal couples would have.  i am not complaining.  i know my role as Her submissive sissy.

But last night Mistress surprised me by telling me that i would be allowed to make love to Her.  i was elated.

i thought She would tell me to get the key to my chastity belt but She didn't.

Instead, She took out a strap on (one i hadn't seen before) and put it on me.  It was approximately the size of Master's Cock, and bigger than mine.

i made love to Her that way.  She enjoyed it very much.  

Afterwards, i thanked Her for the privilege of doing so.
