My girlfriend, her best friend, and I all live together.

Her best friend really has no boundaries; she usually acts like I’m not even there at home—wearing camisoles, pajamas, and sometimes semi-transparent outfits wandering around the living room, talking with a flirtatious smile.
At first, I pretended not to see, but after a while, I really couldn’t take it anymore.
Last night was even more outrageous...
My girlfriend was drunk and collapsed on the bed, unconscious.
I just got her settled, and when I came out, I saw her best friend leaning against the doorframe, looking at me...
That look in her eyes, it was off, very off 🙂
She didn’t say anything, just stared at me, then slowly walked over, holding a glass of water, and handed it to me saying: “You’ve worked hard.”
She’s usually carefree, but her words were especially gentle at that moment...
My heart tightened, and I wanted to pull my hand back. She gently smiled, then moved a step closer to me...
Then she froze, and the only sounds in the room were breathing and my girlfriend sleeping deeply inside...
Then she softly said:
“Today is KFC Crazy Thursday, send me @E5@50!”
