Jon and Zoe continued fucking for quite some time, Jon pumping her enthusiastic body for awhile, the switching positions so that she was above him controlling the action. He came in her repeatedly, his cock never flagging, her enthusiasm only increasing with her orgasm count.
Jon felt another climax rising. For some reason he couldn't quite discern, he suddenly decided to pull out of his excited sister, yelling at her to swallow it, to take it all, which she did immediately, turning around and taking his cock into her mouth, the sensation of her lips around his penis pushing him over the edge. He came hard into her throat, pouring his seed down into her stomach, as she desperately tried to swallow fast enough, orgasming herself while sucking on his spraying dick.
As Jon's climax wore down, Zoe stood up, licking her lips, clearly enjoying the taste. Jon lay back on the wall, taking in the afterglow.
