Mackenzie takes off her dress; Marianne teases her further

Marianne released Mackenzie. "Stand up, Kenz." "Yes ... uh ... Ma'am." It was still difficult to say the words, but not as hard as before. The redhead adjusted her dress as she rubbed her ass absent mindedly, waiting to hear, excited and scared, what her friend (was she still her friend?) was up to next. Marianne looked at her smiling. "Stop playing with the dress and take it off." Mackenzie flushed in embarrassment, but didn't protest. She looked down demurely as she undid the zipper and let her dress slide away, revealing her full, pillowy breasts, her narrow waist and her generous hips supporting a perky ass that topped her lender, long legs. The metal of the chastity belt stood out, glistening and snugly encasing her mound.

Marianne stared for a moment or two. Mackenzie looked hot. Perhaps too hot, judged Marianne, and, normally, this should have made her very jealous. But Mackenzie's newfound subservience, and particularly that she benefited from it made her see things in an entirely new way. Instead of jealous, she felt possessive. And once again, jealous. She wondered what happened inside that snugly wrapped chastity belt and in Mackenzie's head. 'Maybe I'll have Bill buy me one too one day...'

Marianne realized she started woolgathering, and focused again on the present reality. She put her hand on Mackenzie's thigh, caressing it. "How aroused are you, Kenz?" "Very aroused, Mari... uh ... Ma'am." It was true. Mackenzie's nipples stood out rock hard. "Kenz, watching you like this makes me fucking horny, did you know that?" Mackenzie looked down incredulously as Marianne's fingers were caressing her thigh. "Uh... I can see that ... uh.. Ma'am." she said, shifting from one leg to another, suddenly aware again of the snug grip of the belt.

Marianne stood up and undid her shorts, sliding down her long slender hips. Mackenzie watched as her friend removed her panties as well, and moved closer, rubbing her mound against her thigh. Marianne's fingers wrapped around her erect left nipple, caressing it, then went on to cup her round full breast. Then Marianne sat on the sofa and spread her legs, licking her fingers with a sultry look and running them on her pussy, slow and sensuous. Mackenzie put her hand between her own legs, instinctively, only to feel the unforgiving metal that kept her away from playing with herself. Her heart sank in frustration, once more.

"It feels so good..." Marianne whispered, visibly aroused at the poor redhead's torment. "I bet you would do anything to be able to touch yourself now... rub your wet pussy... Is that so slut?" Mackenzie answered faintly. "Yes, Ma'am." "Well I can't let you do that..." Marianne went on with her cat and mouse game. "... but you can try mine. Do you want to play with my pussy, slut?"
