The wife and I went to a party at her friend's house out in the suburbs Saturday night. Nice house with I will admit is a pretty kickass backyard setup with a pool, bar and lounge area with big screen tv, fire pit, etc. Her friend's husband is some sort of IT sales guy or something and clearly pulls in some serious coin. The party was a few of my wife's other friends from growing up and their husbands, but mostly just people from their perfect little suburban neighborhood, which pretty much means a bunch of other moneybag, douche sales guys and their trophy wives as well. Not typically my scene, but hey, I'll drink your booze and eat your food. Her friend's husband is a little older and has an 18 year old daughter from a previous marriage. Her and some of her friends were hanging around the party, swimming in the pool and hanging out in their basement game room. His daughter is pretty freaking hot. From what my wife told me before, this guy's ex-wife (the girls mom) was a college and NFL cheerleader and her daughter clearly got the body from her. Most of the daughter's friends were damn sexy as well, granted in my late 30's almost any 18 year old chick looks hot. And what girls these days pass off as bathing suits, sweet jesus, I could not stop staring. Anyway, I admit I was pretty turned on watching these girls and was definitely sprouting some chub in my shorts. I had a few drinks in me and needed to break the seal and take a piss. I went into their main floor and found that someone was in the bathroom there. So I walked upstairs to find another bathroom as I really needed to piss so didn't want to wait. As soon as I got to the top of the stairs there was a bathroom straight ahead so I went in there and closed the door. Right away I noticed that there was a second door in the bathroom already opened that connected to a bedroom where a light was on and it was clearly the daughter's room. Typical teenager room that was a mess with clothes thrown everywhere & posters on the wall. So I pulled the door shut and started to take a leak. The toilet was positioned under a window that when looking out you looked right down on the back yard and the pool. Looking down at those beautiful young girls and already having a semi-chubby I started stroking my cock a little as I pissed. Then I noticed next to the bathtub was a clothes hamper and sitting right on top was a pair of sexy teen panties. Right then my cock grew to rock hard. I grabbed the panties and held them to my nose, took a deep breath in and could smell the scent of her sweet teen pussy and ass on them. I stroked my cock hard and fast while sniffing those panties and watching her and her friends out the window in the pool. Within seconds I felt my load building up and right when I was about to cum I wrapped her panties around my cock and blew my load inside of them. I admired them one more time and put them back on top of the pile of clothes in the hamper. I was so tempted to push things a little and go snooping around her room, but didn't want to get caught and cause a huge scene. I washed my hands and headed back downstairs. Right as I reached the bottom of the stairs, the daughter was coming in the sliding door with a towel wrapped around her and kind of gave me a "why the fuck are were you upstairs" look. I smiled at her and said, "Hope you don't mind, I think I just used your bathroom since someone was in the one down her." She looked back at me with a disgusted look and said, "Whatever, you better not have taken a shit in there." and she brushed right past me rushing up the stairs. Ha, whatever was right sweetie, I certainly didn't shit in your bathroom! I walked back outside, went over to where our host was at the bar, he offered me up another drink to which I readily accepted and then when he handed it to me he said, "Hope you're enjoying yourself and help yourself to anything, what's mine is yours bro". I think I nearly spit out my drink laughing when he said that. I certainly had enjoyed myself and when we got home, I fucked the shit out of my wife thinking about his daughter's sweet pussy.
