A few months into the relationship with my ex (Master/slave relationship) I had come to find out and when she was younger her older brother and convinced her and they fucked a lot.

Whenever they were alone for time frames or babysitting her

Other times sneaking into her room late at night

even a couple instants with company over sneaking off to "play hde and seek"

once she had confided it to me and realized I was quite interested and aroused by it she would talk about it often especially when we were having sex.

Even one time agreed to try and seduce him while we were together (they had not in many years) however despite her efforts it did not happen.

She also tried to seduce her step father on my command. Being flirty, leaving her door open. Caught him watching a few time but never tried anything sadly.

We had talked about idea of letting her son watch or join in time, playing on fantasy talk while having sex.

On top of all that she had a high body count before we had gotten together. Definitely why she was such a great fuck. Sleeping with guys she worked with (some even at work), friends of her ex (while they were together and after), a couple of my friends who need to get laid, and even her dealer and guys for weed.

She definitely opened me up for more interest in a taboo world and active girlfriend. We had talked about other ideas... Public .. k9... Her son. None came to tho before she moved and we ended things.

Finding another local or long distance girl with a similar mindset has been my goal since, as tough as that is unfortunately it has not happened yet.
