College Made Me Very Sexual

I returned home after my first year of college and found myself very frustrated sexually, I was pleasuring myself all the time, our family lived out fairly rural with no guys my age around me unless I went to town. Truthfully though I only dated a few guys in high school and none of them now so honestly had no other guy to turn to except my brother. Gross right? He was going into his senior year and I thought he would just freak out when I brought it up but luckily for me he was completely into it.
We never kissed or cuddled if you will, probably the rawest sex I have ever had in my life, we were completely centered on each others pleasure not concerned about a relationship or feelings really. I think it made us closer looking back on it all and to this day are still close.
I went to his room one morning shortly after our parents were gone to work, I purposely had on just a t-shirt hoping he would get visually excited seeing me thru it. I sat down on his bed across from him and saw his eyes immediately go downward staring at my pubic hair and vagina visible above my foot. He commented that Um, I was showing and I asked him if he wanted to play with it. HIs eagerness surprised me a little bit barely even hesitating and saying yes then admitting that he always enjoyed it when I walked around the house without a bra on like mom does. The pervert had been eyeing both of us all the time and again was surprised at how well this was going.
I was naked in seconds, T-shirt on the floor and his fingers all over my breasts and the rest of me, I laid there on his bed being caressed for quite some time before telling him I wanted more, like his mouth on my vagina. He was very willing and eager but I had to be quite verbal on how I wanted it done or end up frustrated, he did anything I wanted him to do and our summer was off to an amazing start for pleasure.
The very first time my lips and mouth went down on his penis he let out a moan and gasp and told me this was his first time receiving a blow job, I was pretty turned on listening to all the praising he gave me and how verbal he was also. I was also trying to figure out if I wanted to go all the way with him or just keep it to oral.
So we played almost daily for like two weeks, he was a very oral giving guy for sure, tongue exploring all areas of me including of all things my toes and the soles of my feet, turns out he has a foot fetish which I was not expecting but came to really enjoy. I got on top of him one day after giving him a blow job, sucked and stroked his penis a lot making sure to get as much out as I could and had a condom ready in my room if he said yes. He said yes pretty quick so I leaned over and pulled it out of my drawer and rolled it down onto him then began rubbing myself on him before lifting it up and riding it.
He was really enjoying it for sure, so was I as I felt his hardness spreading me apart, also learned that day that his ability to last a long time was pretty great, we often did this for like fifteen minutes with me ending up with some bruising now and then on my thighs. I knew his first serious girlfriend was going to enjoy it a lot and probably thankful I gave him quite a few lessons on pleasuring a woman.
I returned to college that fall feeling like the summer was too short, he was so far the only guy I had been with that was a very eager oral pleaser. I had one boyfriend in college that did not even like to give oral, dropped him pretty quickly after that night.
