Birthday Surprise

I was dating a girl and was open and honest with her about me being bisexual and being with guys. Early on in the relationship she asked me a lot of questions and what I have done and the guys I have been with. I told her that I had been both top and bottom but enjoyed being the bottom more, especially if the guy had a larger cock. I am about 6 inches hard. We talked about one day maybe having a threesome but that was about it.

On my birthday a few months later, I came home from work and she told me she had a surprise for me once I came out of the shower. So I showered, came out, she told me to stay naked, to put on the blindfold, and lay down. I felt her start sucking my cock, and then she said now it’s time for the surprise. I was confused. All of a sudden I felt something on my face. I pull my blindfold back and see the largest cock I have seen in my life. It had to be 10 inches. My girlfriend just grinned and kept sucking me.

I reached up and started sucking the tip. I rubbed up and down his cock. I was in awe. My girlfriend crawled up to my face, kissed me, then started sucking his massive cock as well. She motions me to turn around. As I’m moving I see her grabbing some lube. I’m nervous and excited at the same time. I watch her rub lube all on his cock, then she rubs it on my ass. She takes his cock and guides it in. His head stretches me and I gasp. I bend over more to open up. He pushes more and it starts to slide in. I have no clue how much is in me but I’m full. Then he picks up the rhythm. I look over and my girl is playing with herself watching his cock go in and out of me. She reaches under me and starts stroking my cock. I couldn’t take any more. I blow my load all on the bed.

He pulls out and is still hard as a rock. My girlfriend whispers something to him and he goes to the bathroom. She says I want you to watch me now. He comes back cleaned off, and walks up to her on her back. She is so wet it slides in with 3 or 4 inches to spare. She starts moaning as he is letting her have it. I start to get hard again watching. She looks at me and asked if I liked watching. I said I did. I hear him grunt and see his cock start pumping in her. She looks at me again and says “clean it up”. As he pulls out, I go down on her. His cum is just pouring out, and I lick up as much as I can. It was warm and very salty, but I was so turned on. She sees my cock and gets on all fours. As I slide in, I can tell she is all stretched out. I push my cock all the way in. I fucked her the best I could. I came in her but not as much as the other guy. We all cleaned up, and thanked the guy. We were both sore the next day.
