The built-up sexual frustration
"Oh my!" Eida rushed into the room, grabbing her phone, which she had left playing on her table when she answered the door.
She had no idea that the phone kept recording whatever happened to them last night. At least, every moment while they were in the kitchen. In her defense, she lost her sanity, at some point, in the middle of that heated moment.
Her cheeks slightly burned in embarrassment upon realizing that her friend might have heard most of it. She might have recognized what was happening in that recording. But then again, she knew most of her secrets anyway.
"I feel like I missed an opportunity to witness a very steamy moment." Amelia teased her friend, knowing that at the time she had stopped the tape, she was on the edge of her final moment of bliss.
She thought it was just a recording of an interview her friend was doing for a piece of article. She did hear a legitimate question and answer portion about love affairs.
