Me and the Mrs. very occasionally experiment with anal play. She is seldom into it and I seldom suggest it (except jokingly) unless we've polished off a few bottles of good red wine. Then we'll be going at it and she'll look over her should and say, "While you're back there..." and she'll grab the Magic Wand while I very gently ease into her...and before long-- and usually, simultaneously-- she'll start to scream and I'll lose control. And it's amazing. And it happens about twice a year, if that.
