My wife has always liked me to be quite rough and forceful in the bedroom, sometimes even asking me to pin her down by the wrists. One night I questioned her about this and she explained the reason to me.

We have known each other as friends since high school, but only got together a year or so after we both left.
She confided that during the summer break of her final year, two of her classmates had forced her.
One day after her mom had left for work someone rang the doorbell. She was in the shower, so ignored it at first, but they kept on ringing, so she eventually she came down to answer the door still wrapped in just a towel. When she opened the front door it was two boys she knew from her class. One of them had been pestering her for weeks to go on a date, but she had declined.

As soon as they saw what she had on, their eyes widened and they pushed passed her into the house locking the door behind them. They soon had the towel off and were eagerly kissing and groping her naked body.
She struggled at first, but knew that no one would be home for hours, so thought that if she let them do what they wanted, they would hopefully leave once they were satisfied, but they were not easily satisfied and kept her naked taking turns with her for most of the day.

I could sense her arousal as she was describing the experience, so I asked if they made her cum. She admitted that she could not help herself. When I asked if it had happened more than once she looked embarrassed, admitting that once they realised that she hadn't told anyone, the boys visited again whenever they knew she was alone in the house.
