Looking to RP a scene where my GF grows her breast at the cost of shrinking my cock.

We have been dating a while and in that time you have been indulging my small penis teasing (Think more “ah poor little guy”, less “ug that's pathetic”) and T&D fetishes. My cock is average (6 ¼ L 6 G ) and its been easy for you to play along with it. Hell you’ were used to telling former BFs that their cock was bigger then it was so doing the opposite was no big stretch.

You come across a magic item / super science device that will expand your breast but cause my cock to shrink. Figure about one cup size for one inch of cock. The effects will last one day but the duration doubles exponential if i cum (if i cum once two days, twice 4 days.) cumming again resets the duration( if i only had 1 day of 8 left it resets and doubles to 16 days). You larger breasts can look natural or fake, perky or saggy (although i do have a thing for larger aureola). What you do not know before using is how good your new breast will feel. Massaging them send waves of subtle pleasure thought out your body, kissing and sucking on your nipples will send a similar sensation to you clit. This feeling grows as your breasts do and may become addictive.

To start, you tie me down and show me the item/device and go over how it works. I don't believe it will work but am proven wrong quickly. it becomes a game of teasing, reminding me how my dreams are coming true and coxing orgasms out of me so you can keep your new breasts, getting right to the point where it would be revered but making me cum at the last second.

Kinks - Tease and Denial, light bondage, Breast, pussy & ass worship, small cock teasing, mild humiliation, size comparisons. Begging..lots of begging.
