Yes and only that

You chuckle and say, "You want me to wear that only? Is that even gonna fit?" Her tone changes again as she quickly interjects, "I see. My pet wants the punishment instead. I would say the punishment is much worse than the uniform." You quickly say, "My apologies, Mistress. I know you have a great sense of humor and I was trying to appreciate the joke if there was one." You walk over and take the lingerie from your sister's hands. You begin to close the door as you change as she stops the door from closing with her hand. Her right breast comes into view as it shakes about. She says, "No need to close the door, pet. Go ahead and strip down in front of your mistress to ensure that your uniform is presentable." You look at her with fear but also feel your erection boucing about as your sister is forcing you to strip down in front of her. You take off your shirt and hand it to her and finally your shorts since you did not put on boxers before bed. She stares at your naked body as you feel yourself blush and try to cover your pulsing manhood. She says as she stares at your gushing erection, "Don't hide yourself, pet. Please continue getting dressed." You wrapped the apron around yourself and pressed your erection against your body. It was peeking over the top of the skirt as it continued to gush pre-cum.

You put on your maid cap and she signaled your to do a twirl, which you did and discovered she was gone when you completed a full circle. You heard her say, "Go make me a bath in mom's bath, pet. I'll be there soon." You felt silly being naked minus a small maid's apron and cap but you know your sister's punishments are no joke. You made your way to your mom's room and into her bathroom as you started to get the bath ready. You made sure it was the perfect temperature and added in bubble bath as well. You did not hear your sister sneak in and you were throughly suprised by what you saw as she checked herself out in the mirror.

She was wearing a stripped long sleeve shirt and you could see her ass peeking out of the bottom slightly. She seemed to be focusing on making sure everything was in place. She went back to making sure the water was good as she quietly crept closer to you and struck a pose. She pretended to look out the window as you finished turning the water off. You went to look behind you where she was and saw she wasn't there. You looked to your left and saw your sister's very naked body on display. She had a leg raised and her pussy was completely visible.

You could feel your erection pulsing against the apron as it demanded to be freed and touched. You knew better since your sister had made the rules perfectly clear and you would rather stay in your good graces. You broke the silence and said, "Your bath is ready , Mistress." You stood up and could see her eyes gathering on the tip of your erection gushing tons of pre-cum. She said, "Very good, pet. I will test it out." You stripped off her shirt and slowly lowered herself into the bath. She let out a content sigh as you stood there like a true butler waiting on his mistress. You watched as her tits poked out of the water and floated like buoys. She must have felt your gaze and asked, "Enjoying the view, pet?" You say, "Most definitely, Mistress. One of the seven wonders of the world." She giggled as she raised her pussy out of the water and said, "Behold the eight wonder of the world then!" You follow up, "Most glorious of the wonders." You both giggle as you both get quiet as you watch your sister's head lay back as she relaxes. You watch as her boobs gently bounce about on the water as well as the water moving between her pussy lips. Your dick is screaming for attention but you know better than to, right?
