This is a request by KattTOMA2 for some cartoon cuties being bound and gagged in catsuits.  We have Lum (AKA Lum Invader) of Urusei Yatsura bound and gagged in a catsuit.

Lum , sometimes called Lum Invader, is the female protagonist of Urusei Yatsura. She is a Oni alien hailing from the planet Oniboshi. She was chosen to represent her kind in a game of tag against a human named Ataru Moroboshi to determine the fate of planet Earth. After Ataru defeats her, she misunderstands his victory chants as a proposal to marry her, thus she forces herself into his life and becomes Ataru's loving "wife' much to the latter's chagrin.

Lum meets Ataru Moroboshi when he was randomly selected by a computer to face her in a game of tag with the fate of the earth on the line. Ataru had been promised marriage by Shinobu Miyake if he could win, and upon catching Lum, he declared "Now I can get married!" and Lum mistook this as a proposal to herself and accepted it. As engagements are sacred on her planet, she's become completely determined to be married to Ataru for the rest of her life, falls completely in love with him, and refers to him as "Darling". Thus she's forced her way into his life as his "loving wife", and violently shocks him whenever he looks at or flirts with another girl (or if he does something to make her mad), but she always forgives him in the end.

Lum's a sweet, innocent, faithful, and good-natured girl, but she can also get jealous and get hot-tempered, usually due to Ataru and his incessant addiction of flirting. However, in early chapters of the manga and at least till the start of season 2 of the anime, Lum had a nasty streak, almost antagonistic towards many of the characters. She even hatched schemes to be with Ataru when Shinobu was involved.
