Chapter 5: by Ben
It's been a few weeks, and me and my stepsister Gina have jerked off with each other and done oral a few times per week. We're on holiday for a couple of days, with three of our mutual friends, to take advantage of a recent heatwave. On the first afternoon, after a long drive, we go to the beach. My friend Megan has a tiny yellow thong bikini that makes a lot of heads turn, and Gina's friend Olivia isn't looking too bad herself in a normal white swimsuit, but I've only got eyes for my stepsister Gina, in her red bikini. I have to work hard to keep my semi from getting out of control, and visible through my swimming shorts. "I can see your boner, dipshit," she whispers to me at one point. We all go swimming. At one point, Gina and I get a bit away from the others and have one kiss underwater, more for the novelty and the excitement of knowing how dangerous it is if anyone sees us.
Back at the hotel, there's a room of four and a room of two. Me and Gina volunteer for the room of two. Megan, Olivia, Raj and Lee take the other room. We go to put our stuff in the room and rest for a bit. "So, what did you think of Megan's outfit?" my stepsister asks immediately, starting to unpack.
"Everyone seemed pretty interested, but I thought you looked much sexier."
"I don't know about that," she says, "I wouldn't mind if Megan ever decided to join us..." For some reason, the thought of me fucking Megan almost weirds me out, like having sex with a friend I've known a long time is worse than having sex with my actual stepsister. "Yeah, well that's a hard sell. I'm not ready to tell anybody about us right now."
"That's okay," she says. "There's plenty more for us to do together for now." She's unpacked some of her clothes and I can now see her panties folded up neatly in her suitcase.
"Speaking of which, we haven't had sex yet...?" I bring up. It's her choice but I have been thinking about it.
"You read my mind," she said, and reached underneath her stack of panties to pull out a six pack of condoms.
"Are you sure you're ready? This'd be your first time with anyone, right?"
"Yeah, but I've been thinking about it for a while. And I thought this holiday would be a nice occasion," she tells me.
"Okay, sure. But just remember that not every first time is great and virginity is just a p---"
"Patriarchal misogynist social construct, I know. But I want to share this moment with you, Ben."
