We were home my twin sister and I. It was around 11:00 AM. My name is Sherry, I was checking out chatrooms. When I had been in K9, it really made my pussy moist. So I got an idea. Our dog JoJo was sleeping by my door. He was four years old, a Collie.

I told Terry that "I want to play a game that I heard on the Internet."

Of course, me being a minute older and stronger Terry agreed. She was in her jean shorts and a cotton top. I told her that I wouldn't hurt her.

So I said "let me tie your hands on the other side of my bedpost."

She quickly agreed. I kept giggling as I did it. The next thought was how to keep her from kicking. I told her we must tie her right leg to my dresser that was close to her leg when she got on her knees. I was getting so excited that I knew my shorts were soaked.

Mean while JoJo laid there watching us. I made sure Terry was secure. She was. I immediately pushed her top above her head to her wrist. I then removed her bra. Pulling at her nipples while I kept getting hot.

Terry said, "Ouch, you're pinching too hard."

I just ignored her plea. Next I pulled her shorts and panties down, forcing then off her left free leg. She struggled some, but I just laughed. By then I thought my pussy would explode!

Terry asked, "Why are you so rough?"

I said "You ain't seen rough."

I quickly stripped off my wet panties shoved them in her mouth. JoJo must have known what was coming because he was jumping around fully aroused. He keep sneaking sniffs of Terry's tight little pussy. I sat up on Terry's back fingering myself. JoJo keep jumping up sniffing my pussy. I let him lick it until I had cum oh so quickly. He immediately tried humping Terry. She started crying.

I told her "STOP THE TEARS!"

Then I helped JoJo mount her. His big hard cock kept missing her pussy, so I got up the nerve and helped it in her pussy. That dog started humping her like mad. I was getting excited and I wasn't the one getting fucked. I fell back on the floor and started fingering my wet pussy hard as ever. With each stroke I felt closer to my climax. After a few strokes I exploded. I looked up and I seen that JoJo's knot was fully pushing into Terry's pussy. Terry was moaning. JoJo had scratched up her back in his fuck frenzy.

All of a sudden JoJo let out a funny growl. I checked his cock quick. Terry's pussy was oozing with JoJos cum and blood. He climbed off of Terry and started licking his dick. That's when I saw that blood was coming out of Terry. Terry laid there limp. She looked exhausted. I leaned over and sniffed her pussy, touching the cum with my finger and tasting it. I saw where the blood was coming from. JoJo had ripped her pussy wide open, you could see the torn skin. It had to have been painful. JoJo got up and started licking his handy work that he had done. Terry started whimpering while JoJo licked her pussy. I gently caressed Terry. She felt so wonderful. I pulled my panties from her mouth and helped JoJo clean that wet pussy. She laid there crying. I inserted my finger in her hole, masturbating it heavily.

JoJo quickly got aroused. He snapped at my hand. All of a sudden he was like a crazed-beast. He pushed me out of his way mounting Terry again. I was scared. I tried to pull him off, but he snapped at me. He humped her hard and fast. All I could do was comfort and hold Terry. I keep crying with Terry, feeling her pain.

After what seemed like an hour or so but couldn't have been no more then twenty minutes he finally finished. He dismounted Terry and walked by the door. I pushed him out and closed the door. I untied Terry quickly but she just laid there limp. I laid there with her, our naked bodies sweating. While JoJo keep scratching at the door. I keep kissing her, caressing her, telling her everything would be all right.

She came too. I helped her on my bed. As we laid there I found myself getting aroused. I slowly leaned down to her breast and took a nipple in my mouth. She moaned with pleasure. I then took my right hand and fingered her wet pussy. It felt so good.

I had remembered the taste and slowly worked my way down her stomach. Kissing every inch on the way. kissing her pussy so gently. She jumped from the touch of my tounge. Terry quickly pushed my head in her pussy and I licked it until my sister cried with pleasure.

That day the only pleasure I received was from my finger, but it was a major turn on watching JoJo fuck my sister. Eventually he fucked me, but that day Terry and I became secret lovers. I still think back of our days playing with JoJo. Oh how I wish we could relive the past.
