Lucy and her older cousin, Nick, were always close. Nick was more than a year older, but they pretty much grew up together and as teenagers they were the family "babysitters" for younger cousins and other neighborhood kids. Nick was physically mature and tall, eventually growing to 6'5" by the time he graduated from college, and he was a popular athlete at his school. So it was inevitable that Nick had some sexual energy toward his pretty cousin. Things started with Nick convincing Lucy to take off her clothes in front of Nick after the kids were asleep. But, unsurprisingly, things escalated.
The third or fourth time Lucy got naked, Nick said that seeing her "got him hard." Lucy knew what that meant, and she had even touched a boy there while making out at summer camp, but she had never seen an erect penis. Nick asked Lucy if he could touch himself while looking at her. Lucy wanted Nick to be happy, so she agreed and got to see her first hard penis. Lucy realized later that Nick was well-hung but she had nothing to compare him to at the time.
When Nick began to masturbate, he told Lucy that seeing her body made him "horny" and he needed "some relief." Soon, Nick was coming into a towel and Lucy saw a boy cum for the first time, which was a powerful experience for Lucy. She was both aware of, and intrigued by, the effect her body had on Nick and his cock.
A few months into their play sessions, Nick "forgot the towel" and surprised Lucy by spraying his cum on Lucy's stomach. He apologized but Lucy was very excited by how obviously turned on Nick was doing that, and after that night Nick never brought a towel. The next few times Lucy felt Nick's warm, sticky cum on her tummy and breasts, then on her breasts and neck, and even a few spurts on her face.
Meanwhile, Lucy was dating more, making out, and letting boys touch her breasts, but she went no further with her dates. Nick was a different story; on Valentine's Day, Lucy touched Nick for the first time and stroked him until he came all over her belly and crotch. She watched Nick's eyes get as big as saucers when she spread the goo around and through her silky pubic hair. After that, Lucy began to please some dates with her hand, nd she was excited by how the boys desperately wanted her to touch them that way. She also realized that Nick had a big cock compared to other boys her age.
A month or so later, Lucy surprised Nick by leaning over and taking his cock in her mouth, her first time giving head. Nick was so excited that he lasted about 20 seconds before exploding all over Lucy's breasts. Lucy immediately realized that a blow job gave her even more power over a boy than her hand ever could. It wasn't long until one of her dates was the first boy ever to cum in Lucy's mouth, and Lucy felt a twinge between her legs as she managed to swallow his load.
Lucy was popular with the boys at school, but playing with Nick still excited her. They babysat together less, though, and Nick sensed that Lucy was experimenting with other boys. One night, Nick told her to sit naked in a bedroom window that faced the street. Each time a car came down the winding road the headlights shone on the front of the house and Nick told Lucy that the people probably could see her. Lucy protested a little, but her heart was beating fast and her stomach churned in excitement at the thought of people seeing her naked.
