Next door teen car washing

My next door neighbors bought their daughter a new car for her senior year in school and she washes it every weekend in the driveway which runs between our houses to their garage in the back. My livingroom side windows as well as my kitchen windows look out on their driveway and while I was jacking off watching porn on my giant screen tv I heard her on the driveway filling a bucket with water. I got up to peek through the curtains on that window . She was bending over adding soap to the bucket and she was wearing tiny cutoff shorts and a bikini top. Amber had the hottest body on her cheerleading squad. She was very short at about 4 foot 10, and her legs were slim and muscular up to her built bubble butt. Her belly with rock hard washboard abs. Her breasts were small and firm with just enough jiggle. Amber had been teasing me from afar for a long time and now I am rock hard and nude just feet from her. I stood there peering through the parted curtains and jacked off to her as she bent over, squatted and reached all over her car. She was playing music and then a girlfriend showed up who was also in short tight shorts. She pulled her t-shirt up and off revealing a bikini top that held bountiful tits. This girl was hot and maybe five feet six inches tall. Her heafty tits had large hard nipples. Now I was so horny I began jacking my cock fast and loud. The two teens were on my side of her car and their hot asses right outside my window and so close to me. I had to cum. I pulled the curtains all the way open and stood looking out at the sexy girls risking being seen. i grunted and shot a big 10 spurt load onto the glass. It felt amazing jacking off this close to two hot sexy cheerleaders and so I kept stroking, smearing cum all over the glass with my cock. Then the real show started when they both took off their shorts revealing thong bottoms and they were taking video of each other doing sexy poses with the car washing sponge dripping suds on their bodies. I quickly got my phone and started taking video as I jacked my cock fast making my balls slap my ass hard. Amber turned around and she looked right at me and saw. She shouted at me," Mr. Smith. You dirty old fucker. Are you enjoying the show?" Both girls began stripper dancing. Amber said," you've been jacking off to our hot, sexy teen bodies." I was crazy with lust and I stood in front of the window showing off my big hard dick. They whooped and I told them to look at my cum on the window. Amber was chanting, "Jack it, jack it hard Mr. Smith". Her girlfriend was saying," Fuck, thats a huge dick. Look at all that hot cum, too. Beat that big fucking dick to our sexy teen bodies, old man". Then they both looked at each other and down the driveway and pulled their bikini tops to the sides letting their sexy tits out. I let out a loud moan at the sight of the girlfriends sexy big tits and hard nipples. They said,"It's so hot watching an old man with such a big cock and balls jacking off for us." Amber said," Damn Mr Smith. That's sexy. How long have you been jacking off to me?". I opened the window and told her since she started driving. I told her to come in and see up close. They both said yes. I let them into my living room and they were excited looking at my cock. I told them i could jack off all day for their sexy asses, but my balls were probably drained already. Amber said, "Mr. Smith, we want to play withl your huge dick. Just let us stroke it for you." I got some oil and let them pour it on my cock then Amber took it in her tiny hand and pulled and stroked it until it was painfully hard again. Her friend Maci took off her bikini top and Ambers too. They were stepping out of their shorts and their thong bikini bottoms were all they had on. It was so fucking sexy. Both girls stroked me and took turns pulling and massaging my aching balls. I felt like I was going to cum again. Amber said,"Mr Smith, I want you to cum on my tits". Maci continued stroking my cock until It spurt out thick wads of cum onto Ambers sexy tits and it drooled down her washboard abs. Maci then wiped my cum all over ambers tits and belly with my cock. I told the girls that I jack off two or three times a day and they could jack me off any time they wanted. They asked me if they could bring some friends form their cheer squad to watch and I begged them to. I told her each new girl that comes over has to get nude and jack me off in front of the others.
