"What?" I asked with what must have been a really stupid look on my face. The thought of it was really weird. My step-sister had just asked me to make her cum.
"Maybe later," Meagan said, smearing my cum into the skin of her perky titties, paying particular attention to the nipples. My cock was exhausted from being so erect for so long and from cumming so hard, but the thought of making Meagan cum was enough to make me want to go again. What did she mean? Did she want me to fuck her? That would be too weird. I didn't think I could look her in the face and shove my cock into her cunt at the same time. Maybe if she faced away from me. Maybe then it wouldn't seem so weird.
Meagan stood and picked her camera back up. She didn't bother to put on her sports bra again. Instead, she stood around topless, like she didn't have any idea her tits were hanging out. I, on the other hand, was feeling really weird. Up until tonight, my encounters with my sister had always been on the level. Sure, she'd always tried to dominate me growing up and she'd always tried to make me do what she wanted me to do, but we'd never had any kind of physical activity beyond innocent tickle fights or even hinted at anything sexual between the two of us. I was practically in a state of shock at what she'd told me about watching me jack off so much and how she'd made me cum on her tits.
"Are you ready to continue?" she asked, pointing the camera at me.
"What do you mean?" I asked in return, covering my cock with my hands.
"Continue... Come on. We're just getting started." She started clicking away again. "Move your hands," she instructed.
"I don't want to do this," I said. My cock was softening and like every time after an orgasm, I was losing interest in being naked and the whole photography thing was getting annoying. I was also struggling with some serious issues about having just sprayed my cum all over my sister's tits.
"Look, this is just going to be between you and me, come on. These are just for fun," Meagan pleaded. "Don't you want to have a little fun with me?"
"For fun? Why do we need to take these?" I asked.
"Come on," she said. "I'm standing here with my tits out to make you feel more comfortable. Just move your hands and let me see that cock of yours."
I looked at her standing there holding her camera in one hand and fondling her bare tits in the other. Watching her hands move across her tits, the tits I just came on, I started losing my inhibitions. Slowly, I moved my hands away.
"Good," she said, clicking away with the camera. "I like that. Stand up for me."
I stood up.
"Good, now turn to the side. I want to see your cock in profile."
I turned to the side, showing her my dick from the side. She was clicking away like crazy.
