Clean inside and out

Mistress stands behind you. you cannot see Her, but you sense Her presence completely. your skin is prickling with the knowledge that She is within inches of your bottom, within easy reach of your arse, exposed as it is to the hot stream of water still running over your naked form. "Pull your cheeks harder", She commands. you strain to obey Her. your forehead is hard against the tiled shower floor, and must carry all the weight of your upper body as you reach both hands around your behind to clasp at your buttocks, spreading your arse wide for Mistress to inspect. "Now that you are clean on the outside, I must commence cleansing you on the inside" She informs you. Her gloved finger smears a cold jelly like substance over your anus, and suddenly you feel a thin, hard pipe penetrating your open hole. Mistress is feeding it in, 10, 20, 30 centimetres ... "I shall not stop until we have a full metre inside you" comes Her voice. The cool pipe is warm now, even hot, and deep within your bowels you feel the enema begin to flow. Hot water from the shower head is still streaming over your body, but the warm water filling you from the inside is much more intense. At first it is a blissful sensation, as the hot fluid stretches you from the inside. Soon, however, you are feeling so full you must burst, and you ask Mistress to stop, please, so that you may release the internal fountain you are holding. "No", She says firmly. "you are to take a whole litre for Mistress". you feel as if it is not possible, yet somehow you manage to hold it in, because She told you to. you dare not disagree or argue with Her; to disobey Mistress is to invite all manner of hell. your entire lower body is at once wonderfully and terribly full. you are one with the water, hot, wet fluid all around you and inside you. it takes all your strength to contain the water Mistress has poured into your arse, and your breath is coming fast and hard now with the exertion. your penis, nearly forgotten, starts to dribble a fluid of its own, as the pressure on the prostate begins to force the semen out. you are about to beg, now, for release, when without a word Mistress withdraws her tube, throws the enema bag onto the floor, and turns to wash Her hands. "Flush yourself out." She orders, "Then wash the enema kit. you have another four litres to go." you hear the click of Her heels across the floor, and Mistress is gone, leaving you dripping from every orifice.
