Hand job From Sisters Friend

I was home from college for the summer the night this happened. One of my guy friends and I had went out to see a late showing of I, Robot starring Will Smith. He dropped me off at my house pretty late at night at maybe 12:30. My parents were long asleep upstairs in their room. The lights in the basement were on signaling that my younger sister was down there and it being a weekend night, probably with a friend. I entered the house through the front door and that's when I saw her in the kitchen. The girl I had a few sexy chats with online. She was standing in the kitchen wearing a t-shirt and skimpy booty shorts. Her ass cheeks were dripping out of the sides. Instantly, I remembered our late night chats together. Describing how we masturbated. Any previous action we received. How she wanted to give me a sloppy, wet blowjob. And almost as instantly, I got hard. "Hi, Jess," I stammered out, always being the shy and awkward type in person. She just smiled and said hi back as she poured herself a beverage from the fridge. She immediately did a double take after she turned her head and saw me. I pretended nothing was amiss and grabbed an empty glass from the cabinet. I nonchalantly brushed her ass with my hard dick as I slid in behind her and opened the fridge. "Jenna is downstairs," Jess said still facing away from me. "I'm just getting us some new drinks." I inched forward, my cock pressing up against her ass. It felt so good that I let out a soft moan. She immediately spun around. "We don't have much time." She planted a kiss on my lips and grabbed my cock through my shorts. Then she quickly fumbled with my belt, unzipped me and dropped my shorts and boxers. Her soft, warm hand wrapped itself around my throbbing cock and she started stroking. I was really young and relatively inexperienced so I knew I was't going to last long. Due to our chats, I also remembered that she doesn't like to show off her boobs since she considers them small. Because of this fact, I only lifted up her shirt part away, exposing her smooth flat belly. When the tip of my cock touched the skin on her belly, it felt like magic. She motioned to me to grab her ass which I complied to with a smile. Her ass in those booty shorts felt so wonderful as she jerked me off. Then I slid my hands up to her lower back and slid them down again under her booty shorts. Her expression changed a devious smile. The sensations of her beautiful ass and her gentle touch of my cock almost brought me to the edge. Unexpectedly, her shorts got pulled down a bit as I fondled which exposed her fully shaved pussy to me. And with that sight, my cum exploded onto her belly and some landed on the floor. As my orgasm subsided, she released her grip from my cock. She quickly grabbed a paper towel and wiped herself off. Got a fantastic look at her ass when she did that. Then she pulled her shorts up, her shirt down, grabbed the drinks, and composed herself. "Hope you liked it," Jess said as she walked by me and kissed me on the cheek. She disappeared downstairs. I stood there for a second dumbfounded by what just transpired. I quickly snapped out it, cleaned up the cum on the floor and made my way to my room with the biggest grin on my face. Best two minutes of my life up to that point.
