Make Tommy blow him.

Billy pushes Tommy down by the shoulders, simultaneously scooting up so his hips meet Tommy's head. Billy's dick pushes through Tommy's mouth. Wet warmth envelopes Billy's dick. Billy gasps, pleasure slowly seeping through his lower half. He can feel Tommy's tiny gags flex his body as Billy's dick goes down his throat. Billy finds himself excited by this, horniness sharpening at Tommy's wide eyes looking into Billy's own. As Tommy's movements get smoother, he gets faster and faster, using his powers so that he is a blur of motion. The pleasure overwhelms Billy, swallowed by ecstasy as Tommy's orchestral movements make a symphony of euphoria within his twin brother. Tommy's movements are so fast, once Billy's orgasm comes, there's no question of edging or slowing. It strikes, slipping in through the quaking vibrations and Billy cums haphazardly, jizz jetting down Tommy's mouth but spraying all over them both.

Tommy lays next to Billy, breathless, and looks over at his twin to see what's next.
