Later that day

Barry supposed that jerking off in front of one's grandma might have devastated some people, but it was just another day in his life. He'd been caught so many times that it was old hat. Not to say that he wasn't embarrassed, he just moved on faster than most.

After getting dressed he ran down to his breakfast birthday party. They ate lots of bacon, he opened presents and then everyone got on wity their day. Other than Dave making jerking off motions a few times, nobody mentioned early, which was fine.

Everyone of them had caught him jerking before. He'd never been that exposed and he'd never blown a huge load like that in front of them, that part was still a little horrifying, but they'd all caught him before.

After the party everyone went their own way, getting ready for their day. Barry went back to his room. He didn't have classes today and he'd taken the day off work in honor of his birthday.

He'd had to have his party in the morning because they all had plans for the rest of the day. His dad was heading out of town on a business trip. His mom was going shopping with her sister, Aunt Val, which was an all day event. Dave was working. And Melanie had band camp or some shit-he didnt really pay that much attention. He just knew that despite being 18 already she still had one year of high school left because her parents had started her a year late, trying to hold onto their last baby one more year.

Barry checked his email, played a game on his phone and then watched a movie. In the meantime her heard his various family members yelling goodbye. By the time the movie was over, he found himself with another hardon. Since he was home alone, he pulled down his shorts and started jerking his big cock again.

He was really getting into it when...
