I woke up the next morning and felt a body pressing against mine, I rolled over and was greeted by Tina's smiling face.
"He likes you," she said.
"Who?" I asked, still partly asleep.
"Steve silly," she said "And he's going to keep you."
I smiled, "I'll come over as often as I can."
"No, he's going to keep you here," I said.
"He can't, I'm married," I said.
"Don't worry, it'll be ok," she said.
While we were talking Tina's hand had moved to my breast and she had been casually playing with my nipple.
I hadn't considered myself lesbian or even bi, I experimented before I got married but nothing serious. As I looked at Tina I was getting turned on.
She had a lithe little body with perky tits and rock hard nipples. Her skin was milky white, areolas and nipples strawberry red, I felt they were calling out to me to come and play with them.
She had long slender fingers which were rubbing and pinching my nipple, my eyes travelled up her arm to her shoulder, it was then I noticed she was wearing a studded leather collar, with the name 'PET' written on it by sparkling stones.
My eyes trailed along her body, flowing from her shoulder down to her slim waist, over her flat stomach with it's belly button piercing. Her tiny waist moving up to her hips and flowing into her smooth legs, leading the way to her delicate little feet and brightly painted red toe nails.
I moved my eyes to her pussy, she was shaven smooth.
Tina spoke drawing my attention away from her body, "Steve left me a couple of presents for you."
She rolled over picking something up off the bedside table, rolling back towards me she held a studded collar in her hand, this one had 'SLUT' written on it.
Tina moved the collar to my neck, "You must wear this all the time unless Steve tells you otherwise."
"Why 'SLUT'?" I asked.
"That is your name for now, Steve may give you a new one in the future," she said "It was my name originally."
"From now on you call me Pet unless we are with strangers," she continued "Also Slut from now on you only refer to Steve as Master".
I reached out touching her collar, "This is the first time I've seen yours," I said.
"That's because Master didn't give me permission to wear it around you until you became his," she said.
Tina returned to playing with my nipple, rolling it in her fingers, squeezing it.
"Are you ready for your second present Slut?" she asked.
"Yes please Pet," I replied.
Tina climbed up straddling my face, "Before Master's present, I have one for you," she said.
Her pussy lips were swollen and red, moisture glistened on them, her vagina gaping, I guessed that Steve had been recently fucking her. I also noticed she had a butt plug inserted, maybe I was getting one of those as a present.
