Ok so for the past few months my girlfriend and I have been toying around with a dildo and have we have really enjoyed this, such a turn on for us both. She also teases me with it, sucking and licking as she would me. In previous conversations we have had, the topic of a threesum has come up and now after watching my girlfriend deepthroat a dildo, the two have now made me wonder what it would be like to watch my girlfriend suck another mans cock, no penetration. Thinking about it does turn me on quite a bit, however I am contemplating on asking her about this and to maybe just keep it as a fantasy to myself! I am wondering if anyone has had this experience or at least lend me your thoughts on the topic. Thanks!
