Changing Room To Bedroom

(All names and places are changed to keep it unlinked) A while back I was talking with people on my phone and my friend Katie texted me and we got talking about her party that night and she started going on about her fixation on changing a dudes wardrobe for a day and making him look different. At the time I needed some new jeans anyway so I decided to let her take me on this little trip around the mall of hers to change my look. I met up with Katie and immediately noticed her cleavage when I saw her, she's a pretty girl but her tits are distracting as shit when she's wearing her casual clothes.. We walked around and looked in all the shops she liked and every time she had me try on new clothes, a couple of times I joked that she could pick out my underwear then she giggled and would say, "That should be fun" in a playful way. After eating and getting a haircut and looking around we came into a store that sold skinny jeans and things like that. I'd never tried skinny jeans on before so when she handed me a pair I thought, "This isn't gonna end well" I walked into the changing room and had just managed to wedge on the jeans but they were so tight I found it difficult to pull them off. I called Katie over and embarrassingly asked her to help me out of the jeans and she just chuckled and said "Thought you were stronger than that" I laughed to try and undertone the awkwardness of her head being right next to my crotch and me having a direct view of her boobs. She pulled them down at the same time as me, it felt like we were trying for ages when the jeans finally came loose and fell down.. but at the same time my underwear slid down from all the constant tugging and grabbing of the cloth to try get the jeans off. The atmosphere filled with tension and nerves instantly as she was at head level with my dick and balls, I didn't know what to think part of me was terrified of how she'd react but another was being turned on by the fact she was looking at my cock and I could see her firm tits so well I tried my hardest to not think about it I knew what would happen next. She finally stood up and immediately I apologised for what happened, she said it was fine and that its not like my cock is meant to stay down there all the time, it felt like I'd just dodged a massive bullet. At this point I was too naive to realise what was going on but her chest was pressing against me. I just mistook it for nothing but then she lent down and started putting my briefs back on me. And as she came up to the top I felt her hand rub against my shaft, her fingers curving around my dick felt so good but I didn't dare say anything to her. After the whole changing room thing we went back to hers for the party she'd been talking about over the phone, she decided to do it since her family was away for a couple days and she had the house to herself. I'm not a big party person but I got talking with people and started having a bit of fun throughout the night, but every once in a while I could see Katie looking over at me, that kinda made me panic since I didn't know if she was going to tell her friends about what happened or not so I kept level headed for time being. Although I found it difficult to keep my eyes away from her at the party since she got changed before it started, she was wearing a tight top and shorts that left little to the imagination, I couldn't not look at her figure. Towards the end of the party everyone started to leave in groups and I decided that I'd walk home to have some time to think about today and what had happened. I was the last person to leave since I most people were off to go to other house parties so it was just me and Katie. We decided to sit in her room and talk for a bit since we were in no hurry to do things, which meant the inevitable was coming. We talked for about 20 minutes before she brought the jeans thing up which made me so nervous my hands shook a little. When we laughed about it a little she stood up and looked at me saying how its unfair she's seen what between my legs and that I hadn't seen hers.. At this point my mind was ready to burst, its like a sexual fantasy come true. She unzipped her denim shorts and pulled my hands over, she guided me towards her silk pink panties and slowly we pulled them down from her legs revealing her smooth shaved pussy, I kept looking at thinking about how much I'd love to do to her. I stood up and pressed myself against her body, my hand sliding down her body working its way to her sweet pussy. We kissed slowly but fruitfully until her hands slipped into my jeans and pulled them down showing my cock and balls. I pushed her onto the bed and pulled of her shirt and began to rub her tits together, I'd been dying to do that ever since I saw a picture of her in a skinny black dress. My dick was grinding against her wet pussy lips as I caressed her sensual body, after doing this for what felt like forever she grabbed hold of my arm and we flipped on the bed, now she was on top. I felt her hand holding onto my stiff cock as she pushed it against her and began to grind. I kept rubbing her nipples and kissing her as much as I could before I felt my dick about to cum. By this point I was breathing heavy so she could tell I was close, she pulled my dick away from her wet pussy and started pumping my cock till I came over her tits and chest, I never thought it could feel that good to cum. I woke up in bed still naked alongside Katie with her back facing me, I just went back to sleep for a few more hours spooning her while my hand was laying on top of her big boobs. Eventually we got up and had a shower together but to make it more relaxed we both masturbated over each other. Finally I went to get changed but when I went for my boxers I saw she'd put them on to see what they were like, at this point I couldn't have cared less so I let her keep them and walked home with no briefs under my trousers. We fucked plenty more times before deciding to make a relationship of it which is still great.
