This story is a follow-up to "Tony's Visit to the Resort". It should stand on its own, but you might be interested in the Resort story.
Mary moved in with me after we returned from our visit to the resort. After a few months, Annie joined us for an extended visit. Usually, Mary would sleep with me, but with Annie visiting, Mary and Annie slept together in the guest room. Not sure how much sleeping was done. Every few days they would start the evening in my bedroom. Once they had taken care of me they moved to the guest bedroom.
Mary had to attend a conference for three days, so she was going to leave the two of us to our own devices. However, she left me with clear instructions, "Tony, you do everything Annie tells you to do. I do not want to come back here and learn that you haven't kept her happy. Do you understand?"
"Yes, I understand."
Mary smiled and said, "Good. Next time I'm away you can be in charge." With that, she knelt down, unzipped my pants, and gave me a blowjob swallowing every drop. "You know I love you. Have a good time. I'll be home soon."
I did understand Mary's directions. I also understood that my ass would be red for much of the time Mary was gone. Annie loved to beat me. However, she would make sure I enjoyed the overall experience. On the first night Mary was away, Annie told me to go upstairs, take off my shoes and socks and wait for her.
Annie entered my bedroom, walked up behind me, and started unbuttoning my shirt. She was wearing the standard male's fantasy costume: sheer shelf bra displaying her nipples, garter belt, sheer panties over the garter belt, seamed hose, high heels, all in black. She took off my shirt and let it drop to the floor. She ran her fingers across my nipples like she was strumming a guitar. "I know how you love it when I play with your nipples." She pinched my nipples with her nails. She changed her approach and grabbed a nipple in each hand and pinched with her thumb and forefinger, twisting and pinching until it hurt. She kept it up with my left nipple but reached into my pants with her right hand to grab my cock and stroke it. "Your cock likes it when I play with your nipples, too." She bit my shoulder while pinching and stroking. She dropped her left hand to undo my belt buckle, unbutton and unzip my pants, and pull down my pants and underpants to let them drop to the floor. She bent over to pull them out of the way.
"I need to show you who is boss tonight. Bend over the bed so I can spank your white ass. I won't hurt you...much. I'm only going to spank you with my hand as long as you are quiet and don't move. If you yell out or move your hands to your ass, I'll get my belt, and I'll stop worrying about hurting you. Do you understand?"
"Yes, I understand."
