"Hey, bud" "What're you doing here?" I reply with a curious tone to my voice. "Well... your mum let me in, is that okay?" Gary said with a genuinely s...ncere look on his face. "Yeah sure, just... I thought you were going to be here at three?" I look at him questioningly "Dude, it is three!" He looks at me as if I'm an idiot. "Shit, must'a been in the shower longer than I thought." "jackin' off in there or somethin'?" he says a little too loud. I close the door tight shut and then look at him. He told us that he'd done this not long ago, and that the levels were fine."You don't want to overfill them; it's quite a strong acid, and you don't want it overflowing or leaking because you put too much water in. And always wash your hands immediately, because otherwise you'll touch your clothes, get acid on them, and your Mum will have your guts for garters because they'll be ruined!"He also showed us how to check the polarity of the car earth."Do you see this negative lead? If you look. Mark is a real stud and has a thick, nine inch dick and can cum several times when he's really turned on as I knew he was now.Joey and I sipped our wine and lifted our glasses from time to time to Mark's lips since both his hands were still squeezing our tits as he watched the show on the stage.It didn't seem long and we had finished off the wine and we all had a little buzz going. Mark slid his hands down, one on each of our tits and then without warning he ripped both our blouses open at the. Suddenly we pass in front of a building and someone’s coming out and he goes in and holds the door for me. He says this place might do; we go up to the roof and its freezing cold and my hard-on goes down. The guy leaves the kid on the roof and tells him we’ll be right back. He shuts the door behind him and we run down the stairs and my dick is hard again, I just cant wait to see this guy with his pants down. We find a spot in a hallway and he drops down pants and underwear to his knees. .
