Romance, love, appreciation, adoration, and Mother's Day. All these things go hand in hand for the mother of your children and the woman that gave birth to you.
But for your wife, you really want to do something that she will never forget. Try taking her out for a candle light dinner and dancing, a romantic walk, a picnic if the weather permits, or romantic, candle lit bubble bath.
Bubble baths are always a favorite, because we never seem to have enough time to slow down and relax. So set up a few scented candles of her favorite scent, find her favorite slow music, soft warm towels, a nice lufa sponge, the kind that are from the sea, some sea salts, and of course, the bubbles.
Make sure the kids are at a friends or family members house for the night. Spread flower pedals on the floor like a carpet, along the way, put up little loving notes set next to a clean robe, a bottle of her favorite wine, a single rose, some comfortable slippers, and so on, guiding her to where you want her to be.
Giving her loving instructions on what to do next, always reminding her how much you love her. Lead her softly, seductively onto the next step until she is relaxing in the tub. Quietly and sensually, approach her and start washing her with the sponge, gazing into her loving eyes, smiling, cooing her into receptiveness. Feeding her fruit, caressing every inch with a tender touch. Gently, washing away the concerns and worries of the day.
By the time you are done, you will have a warm, loving, beautifully, adoring wife that will probably follow you anywhere. Take her to bedroom, lay her down, and give her the next step which is a massage with warm scented oils, finishing what the bubble bath didn't get. Now remember she may fall asleep, but don't worry about it, this is all for her. She will remember this and pay you back in full with interest.
