How my best friend/roommate’s sister became my fuck buddy, and more… (M/F)

Backstory to start:

This story begins with me (21) and my best friend Ryan (22) living together in down town of a very large U.S. city, as we were both going to school at the same university, and have been best friends since 8th grade. Ryan and I always talked about going to school together and we were both lucky enough to get in to the same school, me on a scholarship. The school isn't too far away from home for us, but far enough that we couldn't realistically live at home. For the first couple of years we stayed in the dorms, but moved out and rented a 3 bedroom house about a year and a half ago. Ryan's comes from a very wealthy family and his father promised he'd pay for all his school expenses as long as maintained a 3.0. Ryan did, and luckily that meant that his father was putting up the rent for our house each month (around $2,000).

Enough with the backstory. This all started about 2 months ago, when Ryan's sister Kate (19) showed up to our doorstep at 1:30 in the morning and started banging on our door. I was up playing some Xbox and Ryan was in his room, so I of course got the door. Turns out Kate is more than a little drunk, and starts spouting off about this party just down the street at a frat house. Kate just started her sophomore year at University, and is pretty much one of your typical sorority type of girls. She's 5'6-5'7, about 120-130lbs and about chest length light brown hair.

So Kate starts talking about this party and how much fun it was, and I finally just asked her why she was here. She told me that her friends left with out her, and that she didn't want to walk all the way home. Our house was just a block down the street from the frat so she was wanting to stay the night. This wasn't the first time she's done it, and so I let her in and she went up to our guest bedroom. I stayed up not too much longer and then went to bed myself. I woke up the next morning to Ryan walking in my room, and asking me why the fuck Kate was there. I told him what happened and he muttered under his breath "unbelievable", before saying he was leaving for class and then work afterwards.

Because Ryan's dad is paying for the house, he got the master bedroom in the house with his own bathroom, and so I use the bathroom just down the hall next to my room and the guest bedroom. When I finally woke up I heard the shower running and figured that Kate was using it. I got up to go eat some breakfast, and when I got to the bathroom I noticed the door was about halfway open. The bathroom only has a glass shower in it, and it sits in the far right corner of the room. Now, I know I shouldn't have, but I couldn't help but look. The shower glass was pretty fogged up, but I still had a pretty good look of Kate's ass. She was facing the shower head against the far wall so I had a great view without her noticing, and caught a few glimpses of her tits when she would shuffle back and forth. Her tits are on the smaller side (probably B cup), but she has some pretty prominent nipples. Small areola but the nipples poke out pretty far. After about 20 seconds or so I was completely hard, and when Kate looked like she was turning around, I quickly dashed down the hall to kitchen.

The shower stopped not to long afterwards, and I sat at the breakfast bar eating some cereal, trying not to look like I had just saw what I did. Kate walked down the hall in to view of the kitchen, and said, "Hey HornedManBeast. Sorry I used your shower, I just felt gross from last night." I told her it was fine and that she could shower here anytime she likes. "Yeah, I bet you'd like that wouldn't you?" I had this dumbfounded look on my face when she said that, and before I could say anything she said, "Don't play dumb. I saw you looking at me." My face felt like it turned bright red at that moment, and I just kind of muttered out "sorry." Kate replied, "It's okay. You don't need to hide it, just ask next time." She then turned around to face the hall, dropped her towel, and walked to her bedroom. Because I was sitting down at the breakfast bar I didn't get to see her the whole time she walked to her room, but the view of her ass out in the open when she first dropped the towel was amazing.

This was just the beginning of our "relationship." More to come.
