It takes Malfoy far too long to get an erection, and Hermione finds herself wishing at one point that he just would so they could get it over with, just get it over with, just get it done and gone and... But he is swearing under his breath ferociously as he tries and tries to get hard, sweating and panting on top of her, his frustration palpable and desperate. His forehead drops to pillow on one of her deeply bruised breasts, and he spits and gasps a slew of hateful curses, his body settling half naked on her completely nude one. Hermione flinches beneath the heavy heat of him at first, but when he doesn't hurt her this time there is nothing terrible in his body on hers. It is a brief reprieve, in a way, covered from the sight of the revelers, a brief moment without pain and violation.
