"So whatcha up to?" April asks, leaning toward you.
"Just readin'." You say, skimming around the article.
April gets up and leans over in front of you, reaching her arm into your lap and shoving it in your pants, and presses her fingers against your crotch.
"Mm." She says. "You're pretty wet." She looks at you, taking your hand and getting you to your feet, and guiding you over to the low-rise, extra-wide dresser-turned changing table and helps you lay up on it. Unzipping and sliding off your pants and spreading your socked feet out, she prepares the next diaper, wipes and powder.
You're staring up at the ceiling as you feel the warmth of your diaper emit a pulsing aura. You then feel a light jolt as your sister presses her hand against the front of your diaper and grabbing hold of the tape. You feel a faint ripping, accompanied by a faint sticky sound as she undoes it and leaves it to the side.
As another two tapes come undone, you feel wafts of air coming up into the new openings, tickling the warmness inside. With the final tape, you no longer feel like you're wearing exactly a garment of clothing, nor do you feel entirely connected or 'at one' with your diaper. At this state, it feels like an excess hanging onto you, soon to be removed.
You tilt your head in and look over at yourself as April grabs the edge of the diaper with her index, middle finger and thumb, and unfolds it, laying it flat on the table. Immediately you feel the cold air against your snugged, wet skin, like getting out of the bath. You feel stuck and unable to move at this phase. You feel that you are helpless now, and your sister has full control of you.
You watch as she puts one hand against the tub of wipes, and the other pulls a wipe from the top, positions it in her hand, and reaches over to your navel, and presses down. She rubs from here down to the start of your crotch in a circular motion, giving you a little tickle. She slides it over to your outer-thighs; giving them both a quick wipe-down, for a cleansing of trace odor and sweat. With that wipe now discarded into the center of the diaper, she plucks another wipe, and puts it up against the base of your penis. She slides her fingers around it, and lifts it up as she holds her grip firmly and slides the wipe up your shaft. She lets it drop, and then gets a new handling on the wipe and takes another grip at the base, giving it another, slightly firmer slide up the shaft. She pulls back her wipe hand, then grabs your penis with her bare hand; holding it up as she puts the wipe against your tip. With some quick motions, she slides the wipe around the circumference, and the gap underneath. She then grabs your tip with her bare hand, then holds your penis out as she performs one slide *down* the shaft with the wipe.
Placing that wipe onto the previous one, she then takes out a third, and uses her index finger to push your dick out of the way as she places it against your balls. Making a basic cup shape with her hand, she swerves the wipe around your scrotum in circle motions a few times. You put your head back down; you can't see it anymore.
She pushes your legs up--and they instinctively rise up in response--and takes the wipe to your bottom; cleaning it out thoroughly before taking one more wipe and scrubbing off your cheeks. She moves the wet diaper out from underneath you and lets your legs drop again. She grabs the fresh diaper, and starts unfolding it and stretching it out.
You watch intently as she scoots it under you, and folds it back over you; the tightness of the garment being stretched up against you feels very comfortable and reassuring. Resultant of your two memories, it's at once a feeling you've known your whole life, and a new, strange sensation. April firmly holds her hand down the front of the diaper to keep it in place as her other hand reaches over and pulls out the tapes. You hear a snap, followed by a soft press against your lower abdomen. This is done three more times, and then you feel April's fingers running through the sides of the diaper, straightening it. With a light tap on the front, your diaper has been changed. April helps you off the table, then goes to throw away the wet diaper and wash her hands.
You stand there with your new diaper poking down under your shirt. You see your pants down on the floor; April usually doesn't put them back on you. And getting them on yourself is always tricky and takes a few minutes. So whatever, you'll go without them.
