Orgasm denial, frustration and chastity makes this a reality.
When your gurl first discharges this way the die is cast, it has to be this way or no way from now on. Your gurl will likely be shocked when this first happens, but no matter, it will reinforce her position as your sexual plaything.
Collecting and feeding her back her gloop completes her humilation, (and makes for great photo’s) and with perserverance and training she’ll get to the state where she begs for penetration (or even semen) as the association of both with relief becomes too powerful to resist.
Now this truly is top quality sissy cuckold control and humiliation! Love this!!
