'RHOBH' Tea Time: Camille Grammer Gives Dorit Kemsley Erotic Gift to Send Stern Message -- 'Shut Your Mouth'

Not only did her efforts further annoy Lisa, they also pissed off some of the other ladies -- including Camille Grammer, who's been desperate to get a muzzle on Dorit since she called her a "stupid c-nt."

Good times.

The ladies all gathered at Lisa's home to celebrate her birthday; Erika Girardi gave her a beautiful scarf, Teddi Mellencamp Arroyave gave her a pink horseback riding saddle and Camille gave her "the most fun gift" -- a sexy bunny mask for her hubby's pleasure.

"I have something very sexual for her," Camille added, handing Dorit a gift bag. "Because this darling told me to get a strap-on."

Dorit pulled out a pink ball gag.

"That's because you talk too much, clearly, so you need to try it on," Lisa interjected.

Dorit -- clearly surprised by the gesture -- refused, saying, "I don't love it and I don't think I'd ever use it, to be honest with you."

"You open your mouth too much, girly," Camille replied. She later told Bravo cams, "I was thinking of a muzzle, but a gag is a little sexier. Hopefully, she'll get the message, which is shut your mouth, bitch!"

Kyle Richards showed up late to Lisa's lunch, so the group filled her in on Camille's little surprise.

"It's meant to be funny," Dorit said to Kyle in front of everyone.

"I don't mind this," Camille replied. "This, to me, is not offensive. It's not like a strap-on."

"She's still harping on something that was a joke a few months ago that I thought we were past," Dorit said.

"Then why isn't this a joke?" Camille asked, holding up the ball gag.

Dorit eventually left the party early because she felt she was being everyone's "punching bag."

Erika, who was at the receiving end of last season's "joke" (PantyGate), later told Bravo cams, "Motherf-cker -- if you, Dorit, do not laugh this shit off, I'm going to crucify you. You cannot cry right now."
