I grew up in Arlington Heights, Illinois, and was a late bloomer. I was also a geek, but in the mid-1960s we didn't use that term. I was a serious student who liked technical subjects and military history. Most of my free time in high school was spent playing basketball with my male friends. I had dates but most girls did not let you do anything except fondle their breasts on top of their clothes while we made out. So I relieved myself by jacking off, usually while reading the few sexually explicit books in my house, like Lady Chatterley's Lover. Spit was the only lube I ever used. After I turned 18 I bought "girlie mags" sold under the counter at a pharmacy in Park Ridge. I hid them in my golf bag. Mom never got in there. I jacked off whenever I could, imagining what a pussy would feel like.
I also rummaged around in my parents' bedroom when they were out. That is how I discovered a jar of Vaseline in the table next to their bed. I was very impressed and mystified that my teenage-boner would shoot white stuff if I rubbed it long enough. I knew spit made it easier to cum. Somehow I made the additional discovery that if I put a glob of Vaseline on my cock, rubbing it was so much more fun than using spit, or anything else for that matter.
When my parents would go out for the evening, I would get one of my girlie mags out of my golf bag in the garage, strip completely naked in their bed, prop the centerfold up on a pillow nearby, grease up my teen-age erection with my new friend, Vaseline, and go to town. Sometimes I would sniff my mom's panties while I jacked. I was such a bad boy! Wow, what orgasms! Back then I just called them cum shots. Teen age boys have such accurate names for things. I soon learned to keep a towel handy to wipe the lube off my hand and the cum off my chest.
Not too much later I discovered sex with my adult neighbor (see my earlier story). I really got excited when we took our clothes off and even harder when he sucked me before he fucked me. He got super hard while he worked on my penis and then he would kneel above me, hold my ankles in the air to raise my bottom, and put Vaseline on his hard cock. It was so glistening and shiny when covered with Vaseline. My little asshole would twitch until he leaned forward and sank into me. I must say he never disappointed me but seeing his shiny hard cock going down to my crotch just heightened my excitement
