We do not swap or share. However, my husband's fantasy was too lick my pussy clean of his cum. He backed out several times due to post orgasmic blues. Then one night after sex and I had cleaned up he said "I wish you had forced me to lick you clean. " The next time we had kinky sex I strapped him down to the bed, slowly rode him cowgirl style and pinched his nipples and told him that once you cum and fill me up. I am going to sit my cum filled pussy on your face and mouth and you are going to swallow everything I push out and lick me clean. He was all excited. I kept it slow and steady. I told him no matter what you say after you cum I am making you follow through. Once he came he tried to talk his way out but I moved up and sat on his face and mouth and watched him swallow twice and enjoyed his tongue licking me clean. I now expect it every time.
