She squirted an extra large blob of shower gel into her hand and lathered up. There was a look of desire on her face, “Let’s see how you like it.�...�� Her soapy middle finger now found it’s way past my entrance and into my anus. Eventually finding my g-spot and massaging it. My already hard penis tow twitched and seemed to grow another centimetre or two.“Hmm, you like it, you like my finger up your bum hole honey ?”I was too lost in the dirtiness of the moment. She was jerking me off with her other. Her breasts were not big at all. I guessed I probably had more cleavage than her, as she was pretty flat. But apparently her nipples were extremely sensitive because each time she pulled or pinched them she would hiss her breath in and close her eyes in obvious sexual bliss. What she lacked in cleavage however, she more than made up in long, long legs, and a heart shaped ass that looked amazingly sexy.We continued masturbating, our little group of three, for another minute or so. Then, several. I just need that click. The one morsel of sound that signals his arrival, that makes my breath catch in my throat and my stomach flutter with need.My eyes are closed making every sound elevated. The cars outside the window and the dog barking across the street. The crunch of the key hitting the lock, and the click as it turns. My click.My hands are clenched behind my back, my head dropped low and obedient. I feel the rush of cool air, diffusing from the outside in. It stirs my skin to react,. It also painted a picture of him that he wanted hidden. A cruel and devious pervert rather than a man who helped people discover their sexual limits. The diary also contained notes of seduction on young women, too young to even experience sex. And Helen browsed them enough that morning to discover who and what David really was. There was now a dilemma. Helen was curious about her host and teacher. The perverted professor of psychology was beginning to open up her own thoughts about human.
