The chorus enjoys themselves at the picnic ("I ain't got no shame"). Sportin' Life presents the chorus his cynical views on the Bible ("It Ain't Necessarily So"), causing Serena to chastise them ("Shame on all you sinners!"). Everyone gets ready to leave. As Bess, who has lagged behind, tries to follow them, Crown emerges from the bushes. He reminds her that Porgy is "temporary" and laughs off her claims that she has been living decently now. Bess wants to leave Crown forever and attempts to make him forget about her ("Oh, what you want wid Bess?") but Crown refuses to give her up. He grabs her and will not let her go to the boat, which leaves without her, and then forcefully kisses her. He laughs at his conquest as her resistance begins to fail, and commands her to get into the woods, where his intentions are only too clear.
