So she always used to roam with her friends. One fine day when I was in my summer vacations I thought of going to her house and staying out there as s...id by my mom as my aunt’s husband was out of station for an official trip and she was alone at home I had to give her company.This time I fixed up I really have to fuck her of any cause. I packed my clothes and left home, reached safely and we went to drop my uncle at the airport and was returning home by our car my aunt was fully tired as she. Now as she was glued to me, one of my hand got to play with her pussy and the clitoris. She was totally drenched, soaked and sopped all in one. Florence showed no resistance, as I removed her shorts and the panties and licked her beautiful looking crack from the back. Florence moaned aloud and held on strong to the wall in front of her face.I showed no dereliction and kept licking her ass crack. The whiff from her behind was intoxicating me with every passing moment and I knew I was getting. There I am on all fours like a proper whore awaiting Dick in my ass. I reach around with both hands and spread my cheeks for her so she knows I’m ready. She says that’s a good whore begging for the Dick. And I sure was, I needed it. She gets behind me, lines up her cock and slides it in just as easy as it slid out. I feel full again and am immediately back in heaven as she begins pounding my ass in the doggy position. She’s gripping my hips like I have hers so many times before and it feels so. “What’s that room for?” I asked.“It is for working with pathogens and things we wouldn’t want to let out of the lab. While we won’t ever be certified, since we don’t want that much scrutiny in our work, we have set it up to match requirements for a BSL-three lab.”“BSL-three?”“Bio-Safety Level. It’s the standard safety precautions for dealing with harmful biological agents. Level one is for the least dangerous pathogens like non-pathogenic E. Coli. Stuff that can be deadly, but can be avoided.
