Sorry, I don't have any sweets to give you" I replied"Really?!" exclaimed one blonde haired girl disappointedly."You got to have something, Mr Smith?"...said the other.It was then as I looked at them closer I realised it was Hannah, and Trisha from my History class, two young bright students who I wouldn't have guessed would be up for dressing up, and trick or treating."I'm sorry Hannah, Trisha but I really don't!" I replied again."Then I guess it has to be a trick then!" said Trisha with a glint. I slowly increased the pace and enjoyed the sex. He was begging me not to stop and was playing with my nipples through his toes. We switched positions and i asked him to sit on my dick. This was the best position for him. After some time he removed the condom and started sucking again. I was so hot i ejaculated very soon in his mouth and he sucked it all. He kept the cum in his mouth and then we kissed and i tasted my own cum through his mouth.I was feeling very happy and then i helped. Notonly was I not supplying the blockers, but I was also administeringessence of testosterone - my macho cum - so I'd tripled the dose, justto make sure.As I was mixing the cocktail there was a knock on the door. Justin wasoutside. I unlocked and let him in. Naked, but for the panties, I couldsee the outline of his thickened but not erect cock through the softmaterial. He walked in, then got to knees in front of me, as perinstructions. Looking up at me from his submissive position, head. I did promise to keep her company in mind when we need to replenish our stock.Andi came to the office about once a month. She did make some sales in my department.

He was a slimy, slippery type. He was probably a good salesman, but he rubbed me wrong, and his products had not changed with the competition.He introduced himself.
