As Betty took my place in the chair I got down on my knees. By now Betty had removed her robe and sat naked in the chair. She positioned her ass near the edge of the chair and spread her legs wide. From my position I could see the lips of Betty's pussy. There was no doubt that Betty was excited. As her clit grew I was amazed at its size. It was a good inch long and as thick as my forefinger.
Placing my hands on her knees I began to softly lick and kiss the inside of her legs. The first time my lips made contact with her flesh I felt a shiver go through her body and she moaned. My tongue and lips slowly continued their journey up the inside of her legs.
"Oh my God!" Betty whispered as she laid her head back and leaned the chair back.
I watched in awe as I saw moisture seep out of Betty's pussy and onto the fabric of the chair. My mouth was now only inches from tasting the juice that was flowing from my Mother-In-law's pussy. I slowed my advance and took in a deep breath. Maybe it was my mind playing tricks on me. I swear I could smell honeysuckle as my tongue finally began to invade her dark forest of hair.
Betty right hand was busy using the computer mouse. She placed her left hand on my head and was slowly running her fingers through my hair. As Betty surfed the web, she found one of my favorite sites. Pictures of threesomes began to come up on the computer screen. The pictures were a mixture of two or three men fucking a woman and of two or three women getting a man off.
"Do you enjoy looking at these kinds of pictures?"
Betty asked as she started a slide show.
"Yes I do." My answer muffled as my lips kissed the lips of her pussy.
Betty's breathing was getting labored and I continued to tease her pussy with my tongue and lips. Her hand on my head was now applying pressure at the back, as she tried to force my tongue into her slit. I applied pressure back. Not quite ready to give her the pleasure she was seeking and needing. Betty move her hand from my head to her left breast and she pinched and pulled on her erect nipple as I ran my tongue up the length of her pussy.
"Oh my!" Betty blurted out.
