Really getting into mini giantess fantasy.  

 Increasingly wanking over a fantasy where I am only 2ft high but have balls the size of two grapfruit and a huge thick 10 inch cock. I am kept as a pet by a 6ft Goddess which huge breasts and a big round butt. She keeps me and several other 2ft guys like me. She uses us like living sex toys. She keeps us all locked in chastity except when she needs sex which it very often.

Sometimes I take the fantasy further where my body is made smaller but cock and balls are remain huge. So big in fact that I they drag around on the floor. And my Goddess uses me like a living dildo.
