Mr. Adams slowly removed his fist from Peter's now widened hole and went over to the cupboard with the supplies. Peter instinctively just continued to stay bent over Mr. Adam's desk. Peter put on the chemical use gloves that he had in storage that covered all the way up to his elbow.
"Now class I'll show you that a fag can not only stretch his hole wide but deep as well." Mr. Adams then move behind Peter as a nervous Peter started to leak more and more fluid as he got more and more nervous. "So kids we have see that he can fit my whole fist inside but now let me show you how far inside my arm can go." The class gasped and giggled as Mr. Adam's slowly inserted his handed in and out of Peter's hole. He took his time intentionally brushing the sides of Peter's hole from time to time to make him moan in pleasure. Everytime he went into Peter's hole he got deeper and deeper and it didn't take any effort at all. Soon the home had accommodated all the way up Mr. Adam's elbow nearly reaching the edge of the glove. Mr. Adam's looked over at the class half of whom were mesmerized and the other half who were disgusted.
Then he looked up at Peter who's face was bright red with embarrassment. "Now Peter show the class the mental control you have over your muscles and suck the glove right off my hand".
"I...I. don't think I can umm doo.." before he could even finish his sentence his hole had clamped down on Mr. Adam's forearm and had started to pull it in. Soon the glove had been pulled off but Peter's hole was just trying to pull in the glove it was trying to pull in Mr. Adams.
"Now now I said the glove and not my whole arm you greedy bottom, now I guess I'll have to really embarrass you in front of the class." Mr. Adams started to move his arm inside of Peter causing Peter to moan and lose concentration on what his now strong hole was doing. Soon Mr. Adams stopped moving his arm and Peter let out a gasp and then a scream. Soon Peter felt Mr. Adams squeezing his insides slowly like he was squeezing a water balloon. What Mr. Adams was squeezing was Peter's bladder, and it didn't take much pressure on Peter's bladder to force it to react pretty severely.
Peter felt he bladder release its entire contents onto his legs and his pants that were below his as Mr. Adams applied pressure. Soon Mr. Adams was able to let go and pull his arm out of Peter's hole.
"Peter, well that was quite a demonstration thank you for being a very enthusiastic volunteer. You ca use your pants to clean up your mess and go take a seat. I'm sure nobody will mind you staying semi clothes after what they just saw." Peter took his piss soaked pants and tried to wipe up his pee front he floor then he waddled back to his desk trying to recover from the new experience that had just happened to him. His mind reeling.
"Now class, who herr has actually had sex? Don't be embarrassed you're still in high school so it's not bid deal." The class partially and tentatively halfway raised their hands, none of whom were very enthused to have the attention turned on them. "Well whether or no you have had sex. Our next demo will be..." mr. Adams said while he looked around the class.
