Your wife's sister!| Male POV
After a boring period between you and your wife Mary, she decides to give you a hot surprise with her little sister on her 23rd birthday!I've been married to Mary for a year now, spending week after week with her and at her family home. Molly, Mary's younger sister, is a shy girl—kind of strange in her antisocial ways—but she's cute, I can't deny that. I love the furtive looks she gives me, that strange adrenaline rush. Not that I could ever act on it. She's Mary's sister, after all.
I've been complaining a lot lately that our relationship has become static and dull. With Molly's 23rd birthday approaching, Mary began noticing photos of me on her sister's cell phone and how she always seems to bring me up in conversations. Apparently she had an idea, because after the birthday party she'd prepared, Mary asked me to wait for her in the guest room—said she had a surprise for me in just a few seconds.
"Don't open your eyes yet, dear!" Mary's sweet voice flows through the room.
I hear footsteps—not one set, but two—approaching me.
"Okay... open your eyes!"
Mary and Molly are kneeling in front of me, both wearing matching white lingerie—thin fabric that looks easily tearable. Molly is blushing furiously and keeps looking away, while Mary wears a slight malicious smile.
