Sarah and I had embarked upon every guys dream. And I suppose maybe even every woman's dream. We both knew where we stood and we were perfectly happy satisfying each others lustful advances, although I think I was given slightly more blowjobs than times I went down on her. Sarah was a mother of two but had the tightest pussy I have ever been in. We used to laugh at her relatively small mouth as well. Especially when I got over eager trying to ram my 8" of thick cock in her mouth. We decided we needed to experiment around the school and started to dare each other. We managed to meet up in an empty staffroom in between lessons and we were no more than in the door when she bent over to show me that she had cut a hole in her tights earlier. My cock was out and inside her instantly. The serious prospect of getting caught meant I pumped her as fast as I could. With the tight squeeze into her very tight pussy, her panties pulled roughly to the side, it all led to me emptying my load in her for a true quickie. I quickly pulled out and wiped the cumm still oozing out of my cock onto her dripping pussy. We walked off and she was telling me she could feel my load falling into her pants. The texts kept flying back and forward as she was feeling extremely horny after our quickie. We decided we would go and fuck in our bosses store cupboard at the back of her room. The boss was out for the afternoon at some CPD course and we had plenty of scope. When we got into her room. In open view of anyone who could have walked in I was told to sit on her chair and Sarah lifted her skirt pulled her pants aside and started to ride me. We bottled it as we heard noises and moved into her cupboard. One of our colleagues came in to the cupboard and asked what we were doing. We said we'd to organise cover and needed textbooks for later and they left. My fingers were straight back inside her pussy as she was bent over facing away from me. I decided I wanted to try her ass. My fingers were pistoning in and out as I kept a vague ear on any potential interrupting as Sarah frigged at her clitoris and started to growl her delight as she gushed over my hands. I started to rub her ass with her own wetness and a mixture of my semen from earlier on. I shimmied up behind her and said I wanted her ass. To my delight and hers she said she loved it in the arse and wanted me in her now. I teased my rock hard cock on her now wet and lubed brown star and then slipped it inside as she continued to frig herself. I laid her lying forward onto a table, spread her legs and lifted her arse to get maximum entry. She groaned again as she hit orgasm number 2. The sight of my cock inside her meaty arse was fantastic and I started slapping her cheeks and pulling on her hair to pull her back onto my thrusts. She was telling me to fuck her hard and fast as she wanted to feel me cumm inside her ass. Her balls reached right under past her pussy as she grabbed onto and rubbed at my balls as she called me for all names. My balls emptied as I pulled hard on her hair with one hand, my other on her Tit and her hand squeezing my cumm out of my balls. I withdrew and she then turned and ordered me to fuck her mouth so that she could taste her arse and my cumm mixed together. Now we both knew it was truly game on....
