Next door driveway

The teen girl next door came to my front door to ask if she could roller skate in my driveway that separates our houses and I told her any time. the single drive from the street runs back to my garage and I have a stoop out my kitchen door to that driveway. She was joined by a girlfriend and they skated in circles and spun until dark. The next day i was in my morning routine in the kitchen with the door open and I heard the girls zipping by and realized i was still in my bathrobe and they could see in. I As i walked to the door to close it my heavy dick was swinging and slapping my thighs and it started growing hard. It parted my robe and poked out just as I shut the door. I could see the girls rolling by through the glass top half of the door and they waved. My cock was still growing as I gazed at their sexy young butts in tight shorts. These hot girls made my cock get fully hard so I began pumping it. Soon I was spurting long thick ropes of cum onto the bottom half of my door. The girls went by and waved again and I secretly waved my dripping cock at them. The next day the girls saw me and asked me to come out and watch and judge them so I put on shorts and a t-shirt and sat on my stoop drinking coffee watching. Wasn't long before looking at their thin tank tops stretched over their perky and firm tits had me growing in my shorts and because I had no underwear on it showed. I had to excuse myself to go inside. The girl skated up to me and stopped as I was getting up and she saw my cock in my shorts. It was throbbing now and making a tent in my shorts. She smiled and licked her lips and I was flexing and bouncing. Once inside I swung the door shut and stood behind it and slid my shorts off. My cock was huge. Harder than ever. Longer than ever. I reached for an olive oil bottle and oiled my cock and balls. Stroking the full length felt so good while watching the girls. Then they both stopped at my door and asked if I was coming back out. I stroked faster and tighter as they watched my arm pumping and knew what I was doing. She asked me to let them watch. I opened the door and they flushed red as I began stiffening my legs. My cock head flared out and my balls crunched up tight around the base of my big cock. I stopped and squeezed the base of my cock making it swell even bigger and veins popping out. The girls mouths were wide open and I poured more oil on it for them making it shiny. I was going to cum hard. They watched as ropes of thick cum began spurting straight out in the air and arcing down onto the vinyl floor hitting with loud splats. The girls were counting out loud 3,4,5,6,7,8,9 and after the last spurt I shook my cock hard throwing more cum on the floor. I stood drained and still erect, still in the moment and proudly displaying my huge cock to them. I told them to look at all my cum on the floor. I called them names like hot, sexy, horny cock teasers. They both vowed to come watch again tomorrow. I told them to bring friends.
