Ask her to dress you up.

"I can't believe I'm going to say this." You begin. "But could you dress me up like you do Sarah?"

"Really?" She seems happy that you suggested this.

""If this is what she likes I should try it." You reason. "At least to understand her better."

"Well strip and get up on the change table." She says. "Before you chicken out."

Until that moment you hadn't considered that this would mean being naked in front of Tanya but it's too late now. You remove your shirt, then your shoes, socks and pants and finally your underpants.

"Don't be shy." She giggles as you climb up onto the table and lay on the padded plastic top. "Babies aren't self conscious."

Tanya reaches under the table and selects a diaper. You watch as she unfolds it. It looks enormous.

"Lift you bum." She directs and slides the diaper under you. "Good boy."

The compliment was delivered so sincerely that it makes you feel warm and tingly.

"These are Sarah's overnight diapers." She explains as she adjusts your penis and then traps it inside the padding. "They are extra thick so they don't need to be changed until morning."

"Overnight?" you ask.

"Yes." She says, helping you down. "I'm sure Sarah will want you to sleep over when she sees you dressed up."

As Tanya crosses the room to the wardrobe, you take a few experimental steps, feeling just how thick the diaper is. It forces your thighs apart and makes it hard to walk normally.

Tanya returns with a baby-blue footed sleeper with little teddybears printed all over it. She double checks the leak guards around the legs of your diaper before helping you into the sleeper.

She completes your outfit by clipping on a pacifier at the end of a plastic chain. "Adorable." she declares before going to get Sarah.

"Oh my god!" Sarah squeals when she sees you and rushes over to hug you. "Thankyou Daniel."

"let's get you changed too." Tanya tells Sarah as she begins stripping her down to her diaper. Finding it still dry, she helps her housemate into a footed sleeper similar to your own but pink instead of blue. Sarah also gets a pacifier just like yours.

"Should we go out to the living room or play in here?" Sarah asks.
