Girlfriends Horny For Another Cock

© 2020 by Tom

My name is Tom and my girlfriends name is Sarah. We’ve been together for around a year and a half now. We’re in our mid thirties and most would say we are both average looking. Actually I think Sarah is above average. I’m still not sure why she’s even with me but I’m not complaining. Every time we make love I can’t believe I’m actually inside her beautiful body. I’m sure some of you reading this know what I’m saying.

We have great sex, usually three or four times a week. We’re both pretty open to trying different sexual things. Occasionally when she’s extra horny she’ll let me penetrate her butt. Ejaculating in her mouth is not allowed unfortunately. She’ll suck on my penis but not for more than a few seconds. She’s scared I’ll lose control and cum. I have to admit it’s probably possible. Anyway I love her so much and feel very lucky to call her my girlfriend.

Sarah likes to tease me. She always has. But not in the usual ways girlfriends usually tease there boyfriends. Whenever she sees a guy she’s attracted to, weather it’s on TV or when we’re out and about, she’ll always say something to me like, “I wonder how big he is” or ” I’d take his sperm anytime.” I play along and tease back telling her to stop trying to make me jealous and quite drooling. We kiss and I pat her on the butt.

This went on for quite awhile till one night while we were having some intense foreplay petting and dirty talk, she suddenly whispered in my ear “if she could try a different cock!!” In the heat-of-the-moment I replied, “sure, anyone you want!” I then pushed my penis inside her and she orgasmed almost immediately. One of the longest I’ve ever seen her have. After I emptied myself into her I rolled off and nothing else was said. We both fell asleep.

The next morning while we were getting ready for work I started thinking about what had happened last night. I wondered if she would bring it up again. I figured she probably would. Now, the way she’d been teasing me all this time made more sense. She’s actually serious about fucking another cock. And I knew I’d better support her desires or risk losing her. I knew it was just a matter of with who and when.

All day at work all I could think about was who she’d be having sex with. I decided we should talk about it tonight. Maybe while we’re in bed like last night.

The commute home was a hot one. It was in the upper eighties and high humidity. I was the first one home so I let our dog inside the air conditioned house. Normally he’s an outside dog but with this heat inside is the only option. His name is Duke. He’s a golden retriever and just a big loveable teddy bear. Sarah picked him out as a puppy a year ago. Sarah and I enjoy taking Duke for walks and taking him to the dog park to run. He’s became one of the family.

After a few minutes Sarah made it home and went straight for the bedroom to change out of her dress and pantyhose and into something cooler. Soon she came out in a pair of short shorts and a tube top. She sat on the couch and Duke jumped up and laid next to her with his head on her lap. I decided a cool shower would feel good so I left them in the living room while I went to the bedroom.

Twenty minutes later I returned and they were still on the couch. Duke’s head was on Sarah’s lap and she was now gently petting Dukes head and neck while she watched Television. On my way to my recliner I saw that Dukes cock was completely out of it’s sheath. Sarah, “looks like Duke really likes you today.” as I pointed to Dukes fully exposed penis. Sarah looked over and saw her dogs impressive penis. All seven inches of it. And over an inch across. Definitely bigger than mine I thought to myself. “Sweetheart I guess there’s no question what he’s thinking about doing.” I teased. Really you think he’s actually getting turned on by me! Yes I’m guessing so Sarah. He hasn’t had the chance to breed a female since he was born you know. Oh, yes I guess so. I never thought about that. You poor thing. Sarah continued to pet Duke.

We watched TV for awhile longer then made some supper. After supper it had cooled down some so the three of us went for a long walk. After seeing Sarah in her tight little shorts and tube top all evening I was getting really horny. It was starting to get dark and I really needed to get my cock inside her so I suggested we head for home. Sarah agreed and we started home hand-in-hand. Along the way I noticed that Duke’s cock was partly exposed occasionally. I’m pretty sure Sarah saw it too. I couldn’t help but wonder what was going on in her head.

As soon as we arrived home Sarah jumped up and wrapped her legs around my waist. ” Tom, baby I really really need you to fuck me now!” Since I’d been hard for the last 45 minutes watching Sarah’s cute little butt in her tight shorts, I wasn’t about to argue. I carried Sarah into our bedroom and gently laid her down on her back. She removed her shorts and panties while I removed my clothes. Sarah had lust in her eyes. She was completely focused on my hard erect cock. She needed to be filled with it. Inseminated by it. Satisfied by it. I held myself against Sarah’s pussy but I didn’t penetrate her for a few seconds. Then I inserted just the head of my penis into her beautiful pussy. Sarah let out a gasp, “oh you feel big tonight.” I allowed myself to gradually go deeper inside her till I was completely engulfed by Sarah’s warm and very wet pussy. Soon my sperm would be flowing from me into my Sarah. Feeling my cock inside her is the most wonderful feeling in the world. It’s beyond description. As I started to stroke in and out of her, she started orgasming almost immediately. She was definitely very horny and enjoying a good fucking.

At one point after Sarah and I started fucking, Duke wandered into our bedroom. This had never happened before since he was usually outside in the back yard. He jumped up on the bed, laid down and started licking Sarah’s face. I continued to thrust in and out of Sarah’s tight little pussy. Sarah looked up at me while petting Duke and said, ” Tom, I think he’s feeling left out.” Yes he probably is. I stopped thrusting into Sarah but kept holding myself as deeply in her as I could. Sarah continued to pet Duke as he rolled on his side to get more comfortable. Oh honey look, Duke’s cock is completely out again. Watching you fucking me must be making him horny. Sarah reached down and lightly touched Duke’s excited cock. Then she started gently stroking it. I couldn’t believe my girlfriend was fondling her dog’s cock. Especially while my cock was deep inside her. “There Duke does that feel good.” Duke licked Sarah’s hand as she stroked him a little harder now. Duke reacted by thrusting his penis into Sarah’s hand slightly. Sarah looked up at me with her big sad eyes and said, “Don’t you feel sorry for him? He needs to have some pussy so badly.” Yes he’s definitely very horny Sarah. And I know how he feels, I have a cock too remember?

I knew what my girlfriend was thinking. As crazy as it sounded She wanted to let Duke fuck her. I was sure of it. But I want her to bring it up. If she was desperate enough to ask for something as unusual as having sex with her dog, then I wouldn’t think of tell her she couldn’t. I started to fuck Sarah again very slowly while I looked into her eyes. I lowered myself over on top of her pressing my body against hers. Feeling my naked body against her petite naked body was incredible. Her hand was still on Duke’s large cock. Slowly at first but then suddenly she entered into a strong orgasm. She was heaving her pussy up against my cock and stroking Duke’s cock much harder now. As her climax peaked she blurred out, “I want Duke to fuck me. I need to feel Duke inside me!!!” As her orgasm subsided, she looked at me to see my reaction to what she had said. Do you really want Duke to fuck you Sarah? She sheepishly nodded yes. Do you want him now? Again she nodded yes. Ok but are you sure you won’t regret it after he’s filled you with his sperm? Yes I’m sure Tom. But tom will you still love me if I do it? Are you going to think I’m weird. No sweetheart I won’t think you’re weird and I’ll always love you. I want you to experience all of your sexual desires. Even having sex with Duke if that’s what you really want. Sarah pulled me to her and kissed me more passionately than ever before. After our kiss I reluctantly withdrew my still hard penis from Sarah. It was looking like Sarah would be receiving her dog’s sperm before mine. Tonight Duke was going to get lucky.

I was having very mixed feelings about what was about to happen. At first thought imagining Duke’s dog cock inside my girlfriend was repelling. But at the same time it was kinda hot. The fact that she wanted it for herself and for her horny dog was a turn on. I won’t know my actual feelings about it till I actually see them having intercourse. I also questioned whether I’d be able to put my cock into Sarah afterwards knowing she was full of dog sperm. Would she even be interested in my cock after experiencing Duke. To many questions, I’m really confused.

Tom, I’m not sure what to do. Well Sarah the way you’ve been giving him a hand job I’m guessing he’s more than ready to fuck you. Just get on your hands and knees and let mother nature take its course. Sarah looked at me very nervously as she followed my suggestion. I leaned over kissing my girlfriend and told her to not be nervous and just enjoy being intimate with Duke.

My suspicions were correct. As soon as Duke saw Sarah on all fours he immediately mounted Sarah and started jabbing his cock toward Sarah’s pussy trying to penetrate her. Sarah was overwhelmed by Duke’s aggressiveness. She started getting scared and told me to pull Duke off her! I held a very shook-up girl explaining to her that Duke was just very excited to mount her and that’s just the way dogs do it. After a few minutes I ask her if she wanted to try again. After a moment she said yes and kissed me passionately. I told Sarah I would try and help Duke penetrate her then he should calm down. She got on her hands and knees and I invited Duke to mount her again buy patting her bottom. He waisted no time mounting Sarah again and started jabbing the same as before. This time he found Sarah’s vagina almost immediately and drove it completely inside her in one quick thrust. Sarah screamed in surprise and pleasure at the same time. OMG Tom he feels so big and powerful. Omg this feels amazing. Sarah could hardly talk as Duke fucked Sarah very vigorously. Then he stopped and held himself as deeply inside my girlfriend as his length would allow. Oh Tom I can feel him ejaculating, it feels so warm. Then she entered into a very intense orgasm, half moaning and half screaming. I’ve never seen her orgasm that hard ever. I could see Duke’s balls contracting as he filled Sarah with his dog sperm. He was having an orgasm of his own. Probably his first, and into a beautiful woman no less. Fortunately his knot was forming outside of Sarah’s pussy. Having his knot inside her is probably more than Sarah needed this first time.

Sarah came down from her orgasm about the same time Duke’s penis slipped from Sarah’s pussy. Duke’s balls were definitely full of cum. It actually flowed from Sarah for several seconds. She collapsed gasping for her breath as soon as Duke withdrew from her well bred pussy.

Sarah looked at me searching for the words to say to me. Finally she caught her breath enough to ask if Duke could fuck her again sometime. I told her “absolutely” as I slid my super horny cock into her sperm filled vagina. Any time you want. In a few seconds I was mixing my sperm with Duke’s.
