[M/f] The Best Birthday Present Ever | 2016

I was with my then girlfriend at the time. We hadn't seen each other for 4 months (distance relationships suck) and we were both super horny and had a lot of pent up sexual frustration from not being with each other for 4 months. When she came to visit we of course had the normal sex, blowjobs, me going down on her several times, etc. But we were looking for something more. My then-girlfriend (i will refer to her as Kara), had always talked about how she was "kind of a freak" before we dated. I decided I wanted to see if that was true. Kara had told me prior to us dating that her last boyfriend did anal with her. Anal sex was always a strange fantasy of mine. I always wanted to feel how tight it was on my cock when I tried it, but had never been with anyone before that I felt comfortable asking to do it with. But Kara was different. We got to talking, and it was close to my birthday. Kara asked me what I wanted for my birthday. I asked her if we could try anal. I was a little nervous to ask in fear of her reaction, but her eyes widened and she shook her head, "of course! BUt why wait until your birthday?" I could feel my cock harden immediately just because she agreed to do it that day, that very instant. We decided we should do it in the shower. I had never had sex without a condom before, and this was the first time I would ever penetrate a girl without one. My shower had a shelf in the back built into the wall for shampoo etc., but it was also perfect for Kara to lean up against. We got the shower up to a very warm, soothing temperature. After washing ourselves for a bit, I began caressing her breasts and making her nipples hard. Her hand was constantly holding my cock and stroking it. She smiled and asked me if i was ready, and of course I said yes. Kara leaned against the shelf with her back facing me. Her ass arched in front of me, similar to how we fucked doggystyle in the shower so many times before. I was confused: "Dont you need lube baby?" Kara replied, "no baby, it'll be fine. Besides, I like it real rough." I was really surprised by this, but chose not to complain. I was nervous but very excited, and my cock was rock hard. I could feel the veins pulsing along my shaft as I anticipated penetrating her. She bent over and I rubbed my cock up against her ass. Her hand reached behind her and guided my cock to the opening of her asshole. I was beyond hard at this point. It was a tight squeeze, but my throbbing cock penetrated her ass and I felt my shaft and head be instantly overcome with warmth. Kara moaned, partly out of pain and pleasure initially. I glided my cock inside her, raw, for the first time. The feeling was indescribable. I took her ass cheeks and spread them apart with my hands as I watched the water flow off of my shoulders and onto her back and ass. Kara was now moaning with complete pleasure, one hand gripping the shelf while the other reached back and massaged my balls. As I thrusted in and out of her, I thought i was dreaming. Never did I believe I would ever be fucking her in the ass, yet here I was doing just that. It didnt take long for me to reach orgasm. I could feel it coming. At this point, Kara had abandoned holding onto the shelf and was now grabbing my outer thighs and thrusting me harder inside her. I coudl feel myself about to burst. I pulled out of her ass and immediately exploded my load of hot cum all over her back and hair. I held onto her from behind for several minutes after, catching my breath and still wondering if i was dreaming Best birthday present ever
