My girlfriend and I have been dating for 4 years and for the last 2-3 I have been fantasising about getting fucked by other guys. But, I have always been too scared to admit that her.

About a month ago I but the bullett and told her. She was confused at first and not very interested but 2 days ago she came to me and asked if I was still interested. I asked what changed her mind and she told me that she just needed some time to process. She also came with a confession that she didn't actually lose her virginity to me as she had told me. But that is for another time.

So, yesterday after we had decided that we wanted to do something we downloaded tinder on her phone and she started swiping. She found a guy that she liked and they planned to go on a date tonight.

Today came and I was so excited. I basically spent the whole day with an erection thinking about what it would be like having my girlfriend fucking another man.

I had a look at the guy's profile: he was really good looking and a lot taller than me. I was already jealous of him and this made me more hard.

The plan was that my girlfriend was going to go on a date with him and then see where it went from there. The hope was that she would bring him back to her parents house and their cottage that we are house sitting at the moment. She would take him into the cottage where they would fuck and I could watch from the window.

So, my gorgeous Eliza went out on her date wearing this gorgeous red dress that I had bought her.

About 3 hours later I am in the main house and I hear a car pull up and two people get out and pay the cab fare. This I know is my que to try and spy in on the action in the cottage.

By the time I make it down stairs and then into the cottage garden. I am looking through the Windows and I can see him. He is way better looking than in his pics and I am immediately jealous. And rock hard. Then Eliza came back into the room and starts making him a drink while he outs some music on the speaker.

They start slow dancing together and I was watching them as he moved his hand down to my girlfriend's Ass. It was taking all my restraint to not get my cock out and start jerking off. I watched as he started to kiss her neck which then evolved into them making out in front of the window. They walked while still kissing over to the couch where he sat down and she straddled him and sat on his lap. They were properly making out now. It looked so passionate and way more intense than anything my gf and I have ever done.

I could see as they were making out that he was lifting up my girlfriend's dress. Her hands were around his neck and she was grinding on him.

Her hands driftes down and I could see her trying to undo his belt. She got it open and I saw her pull out his cock. It was big! Way bigger than mine. Then I came in my pants from the pure excitement and knowledge that my girlfriend was going to be fucking a big cock. It was a fantasy come true.

Eliza was slowly jerking him off as they made out. Then she slid onto her knees on the floor and started kissing his cock. I could hear her laugh as she stoked it and looked up at him.

Then she started sucking him off. She was really going for it and it was really vigorous way more head bobbing than with me. By this point i was hard again.

Eliza was obviously doing a good job because he was moaning. I watched as he place both hands on her head and forced it down onto his cock.

Then after a few minutes of a bj I could just make out her saying "omg, I need you inside me."

Still kneeling she pulled off his jeans and undid his shirt. She them straddled him again and I saw him pull the lingerie that she had on under her dress (that she never wore for me) to one side as he held his meaty cock up right as Eliza lowered herself down.

I watched in awe as she slowly at first bounced on his cock. Getting used to his size. Then she got faster and faster and I could hear her moaning really loudly.

He was reaching round her back and unzipping her dress as she rode him. Then her dress fell away and I could see her perky titties bouncing.

He then picked her up and was carrying her and he turned her around so that they were fucking missionary of the couch. Almost immediately I heard her say "I'm gonna cum, I'm gonna cum". And sure enough her body writhed with her orgasm.

It was at this point that I realised that they weren't using a condom even though i use them with her and we put some in the cottage especially.

I watched as he pulled out while she recovered. Then she rolled over onto her stomach and he got behind her and fucked her pronebone.

Her moaning was loud and he must have been going so deep. I could see her face now and she looked like she was in pure extasy and was in heaven.

Watching her face and listening to her moans and little squeals as he started spanking her was next level and without even toughing my cock I came again.

I heard her yelling that she was going to cum again and as she started her orgasm he presse her head down and fucked her through the orgasm.

Then it was his turn. I didn't hear what he said but I could hear Eliza say "inside me! Inside me!"

I watched as he did his last few big pumps into her as he came inside her. Now bare in mind that she is not on birth control and they are not using the condoms provided. This for me is what tipoied to being better than the fantasy.

He then collapsed ontop of her and they started laughing and kissing and smiling again.

They lay there for ages just chatting and looking at eachother and kissing until I noticed Eliza's hand stroking his Alpha cock again. They were kissing and then she got up and walked with him into the bedroom. I snuck along the garden to see Eliza laying down on the bed while her man came up to the window forcing me to duck. Annoyingly he closed the curtains.

I liste for about 40 minutes as they fucked again. This time i could hear more moaning and dirty talk and spanking. Then some loud moans from him and then back to relative quietness.

I wauted another 25 minutes out in the cold and liste ed to them laugh chat and kiss. Then I came in here had an amazing wank and now have written this.
