Ruth and I usually watch TV for an hour or so in the evening. We were sitting on our couch in front of the TV while Blue, our two-year-old Bull Terrier, lounged on the sofa with us. Bored by the TV, he went to the door and looked back at me. I went to the sliding glass door, pulled it open, and let him out. A few minutes later, he was back at the door wanting in. I got up again and opened the door for him. Blue was almost pure white with a big black patch around his left eye. He seemed restless and chased one of his toys for a minute while I went back to sit next to Ruth.

I didn’t think the TV show was that engaging either. Ruth and I had been married for two years and were still exploring sex with each other, still experimenting. Sitting next to her, I started exploring the inside of her thigh. On the other side of the room, Blue started licking his penis. Soon he was humping a stuffed toy. We had seen him do this before, and I knew that the toy wouldn’t work. I picked up one of the pillows from the couch and threw it to him. We had given him a pillow a couple of times before. He looked up at me as if saying thanks and started humping the pillow.

I slid my hand up her leg her to where her panties covered her bush. Through her panties, I felt her slit and pushed my finger in. Her clit was already hard. Across the room, Blue had his front legs holding the pillow he was humping. He stopped for a minute and licked his penis again. It was out of its sheath and starting to enlarge. Instead of watching the TV, Ruth was looking at Blue.

I’d been thinking about what it would be like to see her with Blue. On one of my sleepless nights last week, I’d laid next to Ruth imagining what that would look like. She was starting to warm up, so I knelt in front of her and pulled her panties off. I put my finger on her clit and slid my finger down to her opening. She was very wet. I unbuttoned her blouse, and she slid down the couch. I figured she was thinking that we were going to have a regular sex session which usually started with me undressing her and then bringing her close to climax by tonguing her. I pulled her blouse off, unbuttoned her skirt, and pulled it off. My naked wife slid forward on the couch and lifted her knees. She was opening herself to me, so I could get my mouth on her clit. Her crotch was facing me, but I could see her eyes following Blue’s action with his pillow. I licked for a minute, but I didn’t want Blue to get too far before putting my plan into action. I pulled my tee shirt over my head and slipped my pants off.

I went to the bathroom, grabbed two towels, and returned to where Ruth lay on the sofa waiting for me but looking at Blue. She sat up with a questioning look when I spread one of the towels on the carpet and dropped the other one on the floor. I took her hand and pulled her down toward the towel. She must have thought I wanted to mount her from behind because she dropped to her knees and leaned forward on her elbows. I slid my hand over her bottom, onto her bush, and felt for her clit. It was hard and swollen. I rubbed it for a while checking how Blue was doing. He’d looked up when we got on the floor and paused his action with the pillow. I motioned for him to come to me. I could see that he wanted to do what I wanted, but he didn’t want to leave his pillow.

A few steps took me to where I could reach his collar and lead him back to Ruth. She hadn’t seen what I was up to, so she flinched when I pushed his nose into her bush. It took only a few sniffs for Blue to start licking her. When she looked around and saw that Blue was there, she realized that the tongue on her clit was Blue’s. She watched for a minute, glanced at me, and then put her head down on her arm and pushed her bottom back. Blue started at her clit but soon moved up to licking her opening. She twitched and wiggled her bottom back and forth. When she began to moan and push her hips back and forth, I decided it was time. I pulled her legs apart; that opened her pussy up.

I picked up the towel from the couch and draped it over her back. Blue weighed about fifty-five pounds. Like all Bull Terriers, he was solid muscle. Even though he was heavy, I was able to lift up his front legs and put them astride her back. The towel protected her from his claws. While licking Ruth, his penis had shrunk some but was still out of its sheath. He started probing to find her. He was too far back, and I shifted him forward until his thrusts made a few hits near her bush. He was probing but missing her vagina.

I took his penis in hand—right behind the knob. With one hand on his knob and the other hand under Ruth rubbing her clit, I guided the tip of his penis into her. When he touched her wet opening, she pushed back welcoming him. He was thrusting with quick doggy motions that rapidly jammed his penis in her. I kept pushing him forward. He continued his thrusts as I pushed him deeper. Just before she took him all in, his penis started swelling up. I pulled him out a little, so I could see his member as it grew.

Having seen Blue with his favorite pillow, I knew that he was going to get much wider and longer. Ruth couldn’t match his rapid thrusts, but she pushed back and forth as if she was trying to take him deeper.

“You want him deeper?” I asked.

“Mmmufh,” she said.

I took that as a yes, so I pushed him deeper. I liked seeing his swelling penis pulling the mouth of her vagina into a ring, but I removed my hand from his penis and placed it at the base of his tail. I could push him forward or pull him back. But I ended up just holding him as he hammered into her, and she thrust back. I pulled him back and saw that he was much bigger. I knew that that meant that he was also much longer.

I pushed him, and he rammed hard. “Mmmufh,” she said again.

I took that to mean that she wanted him deeper. I pushed him from behind. Several moans came from where she had her head down. His knob was pressing on her opening. He thrust harder, and I saw the knob pop inside her.

“Oh,” she said.

He stopped moving, which I knew meant that he was locked in her and swelling up inside; he would soon begin pumping semen. His knob would hold him in there while he emptied himself in several jets. While he was locked and still, I turned my attention to her clit. She was already on the edge, and it only took a minute of me rubbing for her body to shake with an orgasm. Rather than relax, she pushed against my hand. I kept rubbing as the semen leaking from her vagina ran down to her clit. Blue made small thrusts delivering into her. She moaned and pushed up driving him deeper, and then her body shook with an orgasm.

Blue relaxed and slid back. His penis slipped out. Watery semen poured out of her. He had stretched her opening so much that it stayed partially open. Blue’s penis softened but was still engorged. I took his place behind her and slipped into her. She was sloppy wet with his semen and very loose. As I moved, her vagina tightened, and semen frothed around my member. From the amount of fluid in her, I realized that Blue had filled her and then some.

She tightened around me as I moved faster. She responded to my thrusts by pushing back against me. I pulled her hips to me as I felt my climax building, and thrust deep as I came. When I withdrew, fluid gushed out. There was so much that it saturated the towel underneath her.

It seemed to take longer for the desire to build up in Blue than it did for me. It was over a week later before he started humping his favorite pillow. We were watching TV again when across the room, he began. Ruth stood up and walked to the bathroom. She was there for a few minutes. When she walked back, she was naked and carrying two towels.
