bladder enema desperate retention

Description: Using an enema bag, i filled my bladder with as much saline as i could take, then held it while i masturbated to orgasm. after i inevitably spilled, spurts escaping with each orgasmic spasm, i slid the tube back into my stretched urethra and topped my bladder up, making it painfully full once again. i repeated this, sometimes losing control entirely and emptying my bladder during orgasm, sometimes just letting a trickle escape. in the end, a full gallon went into my bladder, stretching it, then came helplessly out again!
