Before Jeff reached his first class, he pulled Henry off to the side of the hall and whispered into his ear. "Wanna ditch first period? I kind if want to try doing butt stuff." Needless to say, Henry had no complaints at all, and accompanied her to one of the usually deserted utility hall restrooms. No one ever came down here because there was no reason too. Only the janitors had business in this hallway, and they only started ariving to the school around the first lunch period.
They slipped into the bathroom and locked the door behind them. As expected of janitors, the place was spotlessly clean, even the grout inbetween the floor and wall tiles looked brand new. Henry quickly pulled down Jeffs panties as what he was about to do suddenly appeared in Jeffs head. "Oh fuck, I am so stupid, he's going to be fucking me in my ass, not her in her ass!" he thought while turning his back to henry. It was too late to stop now though as his panties already were off. Jeff was so nervous that his common sense had left him. He felt like he couldn't bail out this anymore since they were late into the game.
Meanwhile, Henry undid his pants and pulled out his cock. Noticing that his girlfriend already was pointing her ass towards him, he hesitated and asked "Hey, wait a minute. Do you not want to lubricate it a bit before we start? I thought you said that you would never do it dry again."
"Wait, Again?!?" Thought Jeff. "Had his sister really already done anal before? Now that he thought about it... Henry had agreed to do this with not a single bit of hesitation. Wait was his sister really that girl who always skipped class to fuck her boyfriend? Actually wait, aren't I skipping class right now just to fuck my, er her boyfriend?" All of these realizations hit Jeff's mind all at once. He was so distracted that he only now realized that Henry had been talking to him this entire time when he tried to groped his chest. Not that he had much of, if anything to grope though.
"Hey, Megan? You in there?" Asked Henry.
"What? Oh sorry, I zoned out there for a second." Replied Jeff.
"Uh... sure. As I was saying. Are you going to blow me first like you usually do, or are we actually doing this the painful and dry way? Because I don't just carry around a bottle of anal lub with me wherever I go."
