"I swear I am not cheating on you Luna." Twilight stomped her hoof. "It was an accident."

Luna turned to Twilight, her eyes brimming with tears. "I surprise you with a visit and I find you in bed with another and you claim it to be an accident. Did you fall into the bed, did you fall between...did you..." Luna trailed off as tears spilled from her eyes.

Twilight jumped across the room to hug Luna. "It's not like that between us. It was a sleepover nothing more. I was only half awake and hungry. It looked like a marshmallow."

Luna pulled away from her marefriend with a sniffle. "A likely story."

"I swear to you, it's not like that. I don't care for her in that way." Twilight hung her head. "I could never do that to you."

Luna looked around the room at all the pictures and gifts that had been shared between the two, her eyes coming to rest on the photo of their first date on the bedside table. She stared at it for a minute before moving on and the picture of Twilight with her six friends became the center of her attention. Tilting her head to the side Luna hummed a little. "She does look a bit like a marshmallow."

Twilight perked up. "I know."

Luna chuckled a little but it quickly turned to a laugh. Twilgiht tilted her head confused. "Are you okay love?"

Luna wiped a fetlock across her eyes. "Yes. I just realized how ridiculous this is. We have been together ten years and you have been more faithful than I would have ever thought. Did she taste like a marshmallow?"

"HEY! What buissiness of yours is it how I taste." Rarity crossed her forelegs and glared at Luna.

Twilight luaghed and walked up to lean on Luna. "I prefer the taste of stars but yes, a little bit."

Rarity;s jaw dropped. "Well I, some friend you are. Not only did you bit me in a very sensitive spot but now your sharing how I taste. This is the last time I share a bed with you."

Luna raised an eyebrow. "You have done this before?"

Twilight blanched and started sweating. "No, of course not."

Rarity grinned. "Only once, and no that didn't happen. Much to my chagrin. She said I could only have her if you were there and could partake."

Twilight blushed and lowered herself to the floor as Luna grinned. "I see, well perhaps we should make her watch."

Twilight groaned and whimpered. "How did this happen, why me?" She was wrapped in a blue aura and shifted to the bed as Luna trotted across the room to a very shocked looking Rarity and the lights dimmed and the door locked.
