�I can see you are enjoying your training, aren�t you, pet,� she said, looking me in the eye. I could do nothing

but nod, knowing that any other response would be interpreted as a lie given the state of my erection. I then

realized this wouldn�t suffice, and said, �Yes, Professor Bascom.�



�I thought so,� she replied, �because like most men ultimately what you want is to please a woman. I agree

you�ve been learning to do that very, very well, my little subbie. And you�ll be happy to hear that your training

is almost over.�



Given what she said, and what had transpired, I suspected that my denouement would be to perform the same

acts on her. That would fit right in with the entire evening, with her orchestrating of the events right from the

beginning. In fact, it would fit right in with everything she had done to me ever since she had first caught me

spying on her and Laura in the bathroom two nights earlier.



She continued to lightly stroke my cock, gazing back and forth at the two other women with a wry smile on her

face. I was getting even more aroused, and was doing everything I could to stop from cumming. Susan looked

at Laura and said to her, �How about you, poor pet � you were pretty aroused grinding your sweet little pussy

on Professor Arnold�s face, weren�t you?� This reminder of my servitude to her, along with Susan�s coarse,

humiliating language to describe it, led to a deflation of my erection just a bit. It must have been a little

humiliating for Laura, also, because she looked down at her hands as she answered, �Yes, ma�am, I was � or

should say, am, very aroused.�



�And I always take care of you, don�t I, pet,� Susan replied to her.



�Yes, Professor Bascom, you do take care of me.�



�Well, then I won�t leave you hanging there, sweetie,� and I thought Susan was going to tell her to mount

herself on my face once again. But to my surprise, she said to her, �You can go ahead and touch yourself.�



I was shocked by this response, but Laura, much to my surprise, did not appear shocked at all. She simply said,

�Thank you, Mistress,� and proceed to spread her legs out, lowered her right hand, and began to stroke it in and

out of her still-wet pussy. There was no sound in the room other than the squishing noise as Laura pistoned her

finger in and out of her pussy.



I surmised from Laura�s response that this must have been part of their routine, that as Laura�s Mistress, Susan

probably made her touch herself to orgasm quite frequently. I looked over on my other side, and saw that Sarah

had apparently recovered from her crashing orgasm, was breathing more normally, and had now propped herself

up on one elbow to watch the action unfolding. Her gaze was glued to Laura as the young graduate student

added first a second, and then a third finger to her first and began pushing all three in and out of her pussy.



It did not take long before Laura�s breathing quickened and I could see she would orgasm soon. I had clearly

brought her to the brink, and the little bit of work she was now doing to touch herself would get her over the

edge. With a loud, �Ohhhhhhh,� she came, the wetness of her pussy now gushing over the bedspread, leaving a

large wet spot between her legs. She fell over, exhausted, on her side in a similar position to which Sarah had

been just a few minutes earlier.



Susan walked over to that side of the bed, and reached down and began lightly stroking Laura�s hair. �There

you go, pet, wasn�t that nice,� she said to her in a soothing voice.



As Laura was able to catch her breath, she responded, �Yes, Mistress, thank you so much.�



�You know I always take care of you, don�t you my dear.�



�Yes, ma�am,� Laura said, still somewhat in a halted voice.



Susan now looked over at me, not saying a word. I looked over at her, not sure what would be happening next,

somewhat curious, but also apprehensive. She reached down, and undid the tie holding her silk robe together.

It fell open, displaying for me once again her shaved pussy and full breasts. Even in the dim light of the room I

could see that her arousal was demonstrated by her nipples, which were standing at attention. It was clear that

she had been enjoying the events that had been taking place.



She shrugged the robe off of her shoulders, and walked over and placed it on a chair in the bedroom of the

suite. She walked around to the side of the bed where Sarah was, leaned down and whispered something in her

ear. Sarah shifted around toward the foot of the bed, making a space for Susan where she had just been. Susan

sat on the bed, and reached over and again began lightly stroking my cock. It quickly grew erect again, for

what seemed like the tenth time tonight. She continued this for a couple of minutes until Laura was able to

recover from her orgasm, and was able to sit up once again. She watched what Susan was doing with rapt

attention, as was Sarah, from where she was seated on the foot of the bed.



Susan turned to me and said, �Okay, pet, you�ve done very well so far. Are you now ready for the final part of

your training?�



�Yes, Mistress Susan,� I replied, looking her in the eye.



�Good, I hope that this last activity will provide you with a clear understanding of your role with respect to

women. After all, that was the purpose of all this, right?�



�Yes, ma�am.�



She smiled at me, and proceeded to get up on her knees next to me on the bed. She then, like the others, kicked

a leg over my chest and began to straddle me. Knowing the drill, I prepared for her to sit on my face like the

others had done, closed my eyes in anticipation of the event one more time, and waited. I felt Susan scoot

forward a bit and pull herself up off of my chest just a little bit, and I got my tongue ready. But then she

stopped.



�Open your eyes, pet, and look at me.�



Not sure she was talking to me rather than Laura, I nevertheless opened them again. She was looking down at

me from above, her shaved pussy only two inches or so from my face, hanging over my upper chest. I waited in

anticipation, guessing that part of her mind game was to make sure I watched her pussy coming down on my

face. �Don�t take your eyes off of me,� she said.



I did as instructed, looking at her without blinking, holding my breath. And then she began to rise off of me,

kicking her leg over to the side, and for a moment, I thought maybe she had relented and decided I had had

enough. I let out a breath, thinking that my ordeal was over.



But then instead of stopping, she continued her rotation 180 degrees, so that she was now straddling me again.

But this time, she was facing toward my feet (and Sarah at the end of the bed). Instead of her pussy being

inches from my face, it was her round, plump ass cheeks that were sitting on my upper chest. I stared at them,

as the realization began to sink in as to what was going to happen. She was so close that I could not take in the

whole sight in one view; I had to swivel my head a bit to look at one cheek, and then the other, split down the

middle by her crack which started four or five inches or so above my chest and went down, disappearing

somewhere in the middle of my chest.



�I told you to look at me,� I heard Susan hiss, grabbing my attention back. I looked up at the sound of her

voice, and saw her looking back over her shoulder at me. �You better do a good job, as good as you did with

the other two, or we�re going to be staying right here for a long, long time. Now get started.�



Before I could say anything, she lifted up her ass, scooted back so that her crack was right above my mouth,

and plopped down right on my lips. For a brief second I thought she was going to suffocate me, as I was taking

the full weight of her upper body on my mouth and covering my nose. But then she lifted up a bit and I

realized she was getting herself settled down on top of me, supporting most of her weight on her knees and

thighs.



I hesitated for a second, never having been in this situation before. In all of our dominance and submission

sessions, Sarah had never made me do this to her. Yes, I had performed cunnilingus on her many times, but I

had never been forced to lick her ass. I didn�t know what to expect; like most, I had the taboo of this being a

dirty, forbidden part of the body. But I knew from Susan�s tone, and from everything else that had happened,

that my ordeal would not be over until I submitted to her demand.



The olfactory sensation was different from the other two women. I definitely smelled Susan�s arousal when she

first sat down facing me, a scent I had experienced before in the last two days. But now that she was turned

around, her pussy facing away from me, the aroma was a different one. There was just a hint of her pussy,

overwhelmed by a stronger, muskier odor that I knew was emanating from the rear part of her body. It was not

disgusting me, it was just different.



I tentatively opened my mouth, and extended my tongue, and began to lightly lick one of her ass cheeks. It was

smooth, covered with a very soft, downy hair, quite different from when I licked her pussy, the outside of

which was rougher and just barely stubbly from having been shaved or waxed some time earlier. I continued

licking around her cheek, as far as I could reach, given that I could only partially swivel my head as she had me

effectively pinned. It was too big to reach all of it, at least from this position, but I did the best I could running

both the tip and flat part of my tongue around her cheek, depositing some saliva where I went. Every now and

then she shifted around a bit, providing me an opportunity reach parts of the cheek I had not yet explored.



After a few minutes of this, I shifted my attention to the other cheek, repeating the pattern. In all of this I

avoided getting too close to her crack, which I could see had somewhat darker, heavier hairs on it from the top

down to where it disappeared on top of my chest. She again shifted around, providing me with the opportunity

to run my tongue all over her cheek again. As I did this, she began to stroke my cock, getting it fully erect once

more.



After a few minutes on this side, she scooted down toward my feet, and I thought perhaps it would be over.

She looked over her should again, down at me. �Very good, my little subbie boy. But there�s still more for you

to do,� she said with a wry smile on her face. With that she stopped stroking me, and bent her body further

forward, so that her large breasts were down around my knees, and she scooted back toward my face. This had

the effect of splitting her two cheeks a bit, and bringing my face directly in contact with the crack of her ass.

She left no doubt in my mind as to what she now wanted me to do. She didn�t need to say anything else.



I again opened my mouth, and with my tongue, tentatively reached out and touched the top of her crack, which

I could just reach in the position she was in. I ran it up and down the part of her crack I could feel, the musky

scent surrounding my face, an intoxicating aroma enveloping me. As I did this, and realizing that the taste was

not unpleasant, I pressed a little harder, leaving a little more saliva as lubrication as my tongue continued its

travel up one side of the crack and down the other.
