"Mmmmmrrrrrrrpppphhhhh ... rrrrrrrhhhhh," Yvonne's choked howl of agony came from beneath her gag. She hopped about one or two steps before loosing he... footing and lurching and swinging around suspended from her wrists. Her head shook violently from side to side as she continued emitting frantic sounds and wrenched on her bindings in a futile effort to free herself.Yvonne regained her feet but was unable to stand still as she danced and twisted and turned and pulled this way and that against. Slowly, I then started to inch my slick finger into my bum, momentarily breaching the anal ring, before withdrawing. I finger fucked my bum, gradually working in more and more of my finger until I easily slid the entire length into and out of my anus. I then started to vigorously finger my now welcoming anus, and I quickly jammed in another lubed finger alongside the first. I fucked my anus for about ten minutes, before withdrawing my fingers and reaching for the little vibrator. I lubed it up,. I didn't know what to do.I touched myself in the elevator going down to the dorm lobby and almost made myself cum.I masturbated thinking about her body for the next few days until I managed to be in the room when she was taking a shower again. And then, dizzy with anticipation, I quietly crept to the bathroom door and watched her again.I just stood there and stared at her delicious body for a few minutes. I could feel my panties get soaked. My knees were trembling. I wanted to touch my wet. She smiled at me and said that she would. I then suggested that she be totally responsible for her own room and bathroom too. That included cleaning, vacuuming, and washing out the bathtub and toilet too. Debbie said that she understood and that a mistress was supposed to help protect her male companion. Interesting thought!Then once the edge had worn off I made love to my teenage mistress for the very first time. Debbie was just as willing as she could possibly be. She had broken her hymen.
