Allen kept porn under his mattress.
Magazines featuring anorexic white women with plastic tits getting pounded by men with perfectly toned abs and too-big-to-be-real cocks.
He didn't keep them because he liked it. In fact, it made him almost physically ill when he remembered they were there.
He made a point to take them out every now and then and crinkle the pages a bit. It made them look as if they had been used. Used-looking straight porn let him escape a whole batch of insults and bruises.
Allen wouldn’t give his stepfather the satisfaction of knowing he was gay.
