"Crawl!" she said.
What else could I do?
I got down on my hands an knees and followed her. Rachel surprised me when she walked past my room then opened the door to the stairs leading up.
She never looked back but turned the corner and walked up the stairs.
When I got to the doorway she was almost to the top. I could see her pretty well because of the street light that is in the alley just behind the house. He pale ass wiggled and swayed gently as she climbed the stairs. I crawled after her and watched as she reached the top step and knelt down. Rachel then lay forward so that her chest and head were resting on the landing. She stretched her arms out in front of her and slightly spread her legs. What a sight!.
I glanced up at the windows that opens above Kathy and Bridget's kitchen sink. I saw the blinds were closed and the lights were out. No worries there. I looked back at Rachel and as I was just a step below her, I could see that her pussy was completely bare and the juices flowing from her tight hole were coating her thighs.
I reached up with both hands and gently took hold of an ass cheek with each hand and gently massaged them and then opened them wide. The lips of her pussy were full and open. I leaned in and slowly placed my tongue flat against her opening. Rachel moaned softly. I continued to massage her cheeks and because of the angle she was laying, I was able to reach her clit. I gently flicked it and Rachel shuddered and groaned. I then took her labia into my mouth and suckled on them for a few seconds. Rachel pushed back and I really began to lick her pussy for all I was worth.
After a few minutes of going at it, Rachel began to grunt like I was fucking her and began really pushing back into my face. I continued to lick but then I focused on her ass. I pulled back and Rachel continued to hump back.
I gazed at her tiny anal opening and remembering what she had done to me, I leaned back down and placed my tongue just below her bud. Rachel froze. I teased the area between her pussy and ass and then slowly licked all around her pucker but never actually going there. I chewed on her ass cheeks and then licked my way back to her clit and caressed it with my tongue. Rachel moaned and gasped but stayed completely still.
Again, I pulled back and I could see her hands were clenched tightly and she was ever so slightly shivering. I bent back down and tenderly placed the tip of my tongue on her puckered opening and caressed it until began to loosen. Rachel remained frozen except for a slight trembling of her body and I could hear her fingernails scraping against the carpet as if she were opening and grasping at the floor.
Suddenly, the light inside Kathy's kitchen came on and I heard water running. I pulled back to look up and then Rachel's hand swung around grabbed my hair and pulled me back to her ass. She rasped "Don't stop, you fucker! Don't you dare fucking stop!" I dug back in and she released my hair and then arched her back. I could feel her body tighten as I continued to lap at crinkled opening. Rachel let out a sob and then I heard her suck in her breath. Her body began to shake and she pressed her ass against my face and started to slowly repeat "Oh my God! Oh my God! Oh my God! Oh my God!" I was a little concerned that she was getting too loud and that Kathy or Bridget would hear us and come to investigate, finding two naked people outside their back door, one with his tongue deep inside the other's butt, but Rachel seemed lost as her orgasm claimed her and I was so turned on that I didn't care if she was heard or not.
