Search the house

"Let's look for a phone," you whisper to Rachel as the strange woman walks away. "There's got to be one somewhere nearby."

Nodding in agreement, your petite wife follows you as quietly as possible, checking the doorway to what appears to be a large library. You can't see anyone perusing the numerous bookshelves so its as good a place as any to begin the search.

"What in the world...," Rachel softly asks, drawing your attention as she thumbs through a dusty tome. "James, look at this."

The yellowing pages are filled with strange diagrams and mathematical formulas, you can't make heads or tails of it, "I don't recognize any of the symbols, do you?"

She shakes her head, "No, but... hmm."

Leaving the odd book behind, you turn a corner and almost bite your tongue off to keep from crying out; facing away from you (thankfully) is a naked woman, perched on top of a wooden table. Her legs are spread, allowing another, younger looking girl to loudly slather her mouth over the woman's vagina.

"Amy!" the woman moans, pushing her lover's head deep between her thighs. "Oh, oh, right there!"

"Mmghf," a pleasured sound answered... though it came from behind you.

Spinning around you're shocked to see Rachel's hand down her jeans, obviously fingering her pussy as she watches the spectacle. You hiss, "What are you doing?!"

Face beat red, Rachel whips her hand back, flecks of her arousal sprinkling the nearby books, "S-Sorry, I don't... I just felt so hot just then... and-"

"Whatever, let's just go," you implore, dragging your wife away from the increasingly orgasmic noises of the library. You never would've guessed, even after seven years of being together, that Rachel was into lesbianism. The thought tugged at your own excitement, but you ignore the half-grown bulge forming in your pants.

Glancing around, your immediate options are to go upstairs or check the entrance hall more thoroughly.
