She's a little shy, and complained to me that she's been looking for a boyfriend, but is having zero luck. She's such a beauty, there's no step-son she shouldn't have an active romantic life. I told her she'd have to fight the boys off if she got on tinder, as pretty as she is. It never occured to her to meet people that way. She downloaded the app, but didn't have any pics for her bio. So we took some. I tried to guide her as to how to reel in these potential mates by escalating to texting and sending nudes, but she confessed she didn't have a single nude on her phone. I'm an amateur photographer, and I take nudes of girls all the time, so I offered to take some of her, promising it wouldn't be weird. Guess what, it was weird, cuz the second she took out those enormous beautiful titties, I went half-mast, not gonna lie. No big deal, I want to suck on my step-sister's titties. That's got to be a normal thought, right?
