"I've crossed some lines here. Did some things I never would have done before."
Memories flood to their minds. Don entering the house, their Dad away with some friends on a golfing event. Moving closer, seeming to forget what they were.
Collapsing on the bed, a tangle of limbs. Pants, grunts, and moans work their way of out of their lips. Don thrusts endlessly into Charlie and he arches his body to meet his brother's, "yes", "more", and "Don" working out of his mouth like a mantra. A few thrusts later and he comes, streams of white coating their naked bodies, and Don follows soon after, falling half on his brother and half on the bed.
A few hours later they awaken and the reality of what they've done settles in their blood. Don gets up, puts his pants on, tucks his shirt into them, and says how this should have never happened.
Charlie says nothing, knowing there was no way to change Don's mind once it was made. He simply sits up in his bed, the sheets pooling around his waist, and watches him leave.
"You're not responsible."
"No, that's exactly what I am."
The younger Eppes pauses, unsure of what to say, until the words fall from his lips faster than he can hold them back. "We could-"
"Look, Charlie." Don looks exasperated as he gazes at his younger brother. "I want to, but we can't."
They say nothing after that.
