In the dim light of their shared room, Daisy and Tess explore each other's bodies, their fingers tracing lines of desire as their stepbrothers watch, wide-eyed and innocent. Mike and Arin's virgin cocks tent their boxers, aching to be touched. Daisy takes Mike's hand, guiding it to Tess's wet slit, teaching him to finger his sister's clit. Tess does the same for Arin, their moans filling the room as they learn to pleasure each other. When Daisy and Tess kiss again, it's with the taste of their brothers on their lips, marking the start of their forbidden foursome.
