Speaking from the Dom side I take great pride in my aftercare. I have a policy to never break the skin. Blood is a turn off for me so I tell that straight to a sub. After a session I will pamper my sub to the 100th degree.
I will give her a warm flower oil full body message. Warm River rocks on muscles that are sore. After the rub down I give her a long hot bath with flower petals in the water and relaxation candles burning. Then wrap her in a silk robe and cuddle for hours as we talk about it. I keep the lights off and only use candle light. After a blindfold normal lights are harsh. Then the next day I will look her over to make sure she is ok another message and long bath. Then I will dress her normally in her favorite clothes. We then go out and I will treat her to ice cream (her favorite thing on earth.)
That is my normal aftercare session.
