With their hands bound above their heads, the couple watched as their stepson, Jason, slowly undressed. Seeing the lust in their eyes, he grinned wolfishly and stepped closer.
"Jason, what are you doing?" the wife, Emily, asked nervously.
"What does it look like?" he smirked, unbuttoning his jeans.
As Jason's hard cock sprang free, Emily's husband, Mark, couldn't believe what was happening. He had fantasized about this very moment - his wife and stepson together in their marital bed - but now that it was real, he felt jealousy and arousal warring inside him.
Jason knelt between them, his cock swaying in front of their faces. He leaned down to kiss Emily, who eagerly returned his kiss as he reached around to unhook her bra, revealing her soft, pale breasts in the moonlight.
