Truck ride home

So this all happened a long time ago at a college graduation party for one of my friends. My wife gf at the time we will call her( V )and I went to celebrate with him and other friends at a local bar . We had a great time hanging out and drinking . One of my other friends who we will call (Ken) at come up to me and told me how great my gf was looking . We all hung out and he kept buying her shots and getting her really drunk . I didn’t think much about it at the time because we had been best friend for 20 years . It was getting late and everyone was. Wanting to go back to Ryan’s house to party more . I was the designated driver for our group and had a slight buz next to the rest of them . 5 of us loaded up in my truck . Ryan and a girl jumped in the back seat of the truck and a instantly started fooling around and going at it . In the front was Me V in the middle and Ken on the other side of her . As we were driving I was really paying attention to the road since I had been drinking some . I noticed my gf had her hand on his leg and mine as well . Again didn’t think much about it . I did not find this part of the story out till way later but apparently . He room started getting hard with her hand there and it pressed against her hand . He then put his hand on top of her and slid it on top of his rock hard cock . She told me he was about an inch longer and way thicker than my cock . She rubbed and played with his cock all the way back to ryans house without me noticing this happening. Now in reality this is all that happened I know this because she ended up getting sick from drinking to much and I put her to bed but let me tell you what I fantasize about happening. When my wife told me the story years later it made me hard thinking about it and we fucked so hard that night ! Ever since then it’s one of the main things I think about when I masturbate . But in my fantasy when she had her hand Was on our legs and his dick started getting hard I picture her stroking on top of his pants . Then she starts rubbing on my cock making me hard as I notice her stroking both of us . This only turns me on more . She unzips my pants and pulls out my cock and then grabs one of my hands and puts it on her pussy motioning me to rub then grabs my other hand and puts it on my cock and tell me to start stroking myself . As I started stroking myself she turns towards Jen and starts unbuttoning his pants as they start kissing . By ‘this time we were parked I front of Ryan’s house . She pulls out he’s cock and starts stroking it in front of me . I couldn’t believe this was happening . I could tell she liked having his bigger cock in Her hand . I was playing with her soaked pussy and she was moaning in between kissing . I had to slow down my stroking myself before I exploded . Next think I knew she was kidding down his chest and opens her mouth and takes all 7” in her mouth . She was working his cock so good . Pulling it out licking all over the tip then taking it all the way to the back of her throat . Ken grabs the back of her head and starts pumping her head up and down and I started stroking my cock faster and faster . He the. Pushes higher head down and keeps it there I know he is about to cum in her mouth . I couldn’t handle it and I shoot my load all over myself and the back of my gf dress .. she takes his load in her mouth and swallows it the looks at me with the happiest smile I had seen in a long time !
