Tensions rise as a sultry sister and her strapping brother find themselves alone, their eyes lingering on each other's curves. The air thick with desire, she taunts him, "You can't resist me, can you?" He growls, "You're playing with fire," as she leans in, her breath hot on his neck. She teases his cock through his jeans, feeling it grow hard. He grabs her, pushing her against the wall, their lips crashing together. She moans as he grinds against her, her pussy aching for his thickness. They stumble to the bedroom, clothes discarded, as he feasts on her breasts and she guides his cock to her eager slit.
