Thank you to those who contributed comments encouraging me to continue the story. In the first part an older couple invites a younger man over to sexually satisfy the wife. In the second the Bull returns and dominates them more. The wife is loving being used by a large cock and the husband is finding his submissive side. In the third part the Bull brings a friend to help dominate the couple. You may wish to read those parts first.
I answered the phone. It was Sir. He "suggested" a meeting at 8:00 PM that evening. I was instructed to meet him at the front door- naked of course. He added that he would be bringing a special guest.
"Not Master?" I asked. No, it would be someone else.
After a light dinner Rita went to "get ready." As the time neared, I stripped off my clothing and sat in the living room. Rita joined me. This time she was wearing a see through negligee. Its black color contrasted nicely with her red hair. Her nice, rounded breasts pushed against the thin material. I could see her nipples already hardening. The top came down to her mid thigh but not much was hidden. She hadn't bothered with the panties.
The doorbell rang. I tried the peephole but sir must have covered it with his hand. I opened the door. Standing next to Sir was my nosy neighbor from across the street who had shown such interest in our previous entrances and exits.
They stepped in and I closed the door. When Rita saw our neighbor her mouth dropped wide open. I realized that I had never told Rita about our neighbor's interest in our visitors. She stood up. Sir said, "Being neighbors, I'm sure you already know one another, but for the purposes of our visits this is Mistress. I am still alpha here but she is next in line." He turned to Mistress. "This is 'boy'- sometimes 'cum slut boy.' And his wife is 'girl'. By the way, boy is not allowed to talk during our sessions. I don't want to open the door to him making requests."
So there we were. Me nude and Rita in a revealing nightie in front of our neighbor. Mistress was blonde with a very pretty face. What I would call pleasantly plump. Her jeans were definitely plus sized and her loose, oversized sweatshirt did not hide the fact that she had large breasts and hips. She carried more weight than Rita but still had a sexy, curvy body. The overall impression of her body was positive and tempting.
Sir looked at Rita. "Wow, girl, you look ready for action today!" MIstress and he must have had some previous discussion about this meeting because he gave her a nod and she walked towards Rita. Mistress embraced Rita. Their chests mashed together. I was surprised at how quickly Rita welcomed her embrace. This was not something we had ever discussed.
Mistress said, "Pull off my top." Rita grabbed the hem of the sweatshirt and pulled it off. My first impressions were correct. Mistress was a bit plumper than Rita. They embraced again. Sir and I watched their tits push into each other. MIstress pushed Rita down onto the couch and stripped off her own jeans. Then she sat next to her and they began to make out. Mistress had her legs open exposing her hairy pussy. But I was not destined to enjoy the sight for long.
Sir removed his pants and sat down in a chair opposite the women. He pointed at his cock which was as impressive as ever. I knew what to do and dropped to my knees. I engulfed his cock in my mouth and lightly ran my tongue around the head. It quickly came to full attention. As I sucked and licked I could hear occasional comments from the women.
Mistress: "It's been a while since I enjoyed another woman."
Rita: "I hope you are enjoying it, Mistress. Are you mainly gay?"
Mistress: "Oh, no. I would say mostly hetero but enjoying some bi when I can."
More rustling and kissing noises followed for a bit.
Mistress: "Yes, girl, suck my nipples. Hard!"
Sucking sounds followed as I continued working over Sir's cock. I thought to myself what a wonderful feeling it is having a cock in one's mouth. I pumped the base as I sucked the head.
Then, Mistress: "Lay on the carpet on your back."
I heard them moving around and could imagine Rita on her back. Guessing that Mistress' pussy was approaching her face.
Mistress, "Oh, yes! Keep that up."
More sucking sounds from both me and them.
Rita, "Oh, thank you Mistress. That feels wonderful!"
I could feel Sir building to a climax. He gave a big grunt. I felt his cum hit the back of my throat. Then it filled my mouth. I kept pumping him slowly. He continued to cum. I savored the taste and began swallowing.
"Good job, boy. You're getting better and better at that. You've certainly earned the name 'cum slut boy'." I nodded and licked my lips. He signalled to me that I could turn around.
The first thing I saw was Mistress' substantial ass pointing in my direction. Rita's head stuck out between the thick thighs. Her mouth was eagerly sucking on Mistress' pussy. When I moved a bit I could tell that Mistress was ministering to Rita's pussy. They were both emitting groans of pleasure.
I could hear that Rita came first. She gave a big grunt into Mistress' pussy. Rita's legs flexed several times. Shortly after, Mistress came. As she did she ground her pussy into Rita's face, maximizing her own intense orgasm. The flesh of her ass rippled as she ground onto Rita.
The women separated and leaned against the couch facing us. Mistress looked at Sir and said, "I heard you cum. I hope you saved some. I plan on feeling that gorgeous prick of yours in my pussy in a bit."
