The next day, I was sure I was going to be in big trouble. It was also the day of our Family Halloween Party, something we did every year. Everyone got all dressed up in costume and we usually had the house jam-packed with people.
Jo confronted me while Mom and Trinity, my sister, went out to buy supplies for the party. So it was just me and Jo in the house for the next hour or so. I wasn't really thinking about it as she came into my room while I was picking out clothes for the party.
Jo came in, spun me around from my closet, and then said, "I want to admit something to you Fred, I was very surprised to find you in the hallway. But there's something I have to ask."
She seemed to be very close to me, slowly inching in until our noses were practically touching, "Um, okay," I said with a gulp, my cock already reacting to having this hot, blonde MILF this close to me, even if she was my stepmother.
"When you were jerking off in the hall, was it because of me...or was it because of your mother."
I couldn't answer, my voice caught in my throat, I knew she figured me out and she smirked.
"I knew it," Jo said with a laugh, "You want to fuck your own mom. That is so fucked up. I can't believe we raised such a little pervert." She laughed again and I could feel my cheeks start to flush.
"Whatever, I-" I started to say but was cut off, quite surprisingly, by Jo suddenly kissing me, this was my second mother after all. Though I fantasized about her too in my jerk-off fantasies I had never expected her tongue to be in my mouth, desperately trying to go down my throat.
I was surprised, but I started frenching her back. She moaned around my tongue as I reached around her and pulled her into my body. She practically jumped on me, wrapping her legs about my waist as I moved my hands to her ass to hold her up while simultaneously copping a feel. My cock was rock hard in my pants as she started roughly grinding against me, I could feel her rubbing her pussy against my cock between our clothes. This was the hottest thing to ever happen to me up to this point and I could already feel myself getting ready to cum, but I held back, unsure what was going to come next.
Jo broke the kiss after about two minutes of making out like that. She put her legs back on the ground and straightened her clothes out. "Now I'm the one who's embarrassed." She admitted. Turning her back to me.
I felt confused by the mixed messages but I asked, "Um, what was that about?"
Jo sighed, brushing her blonde hair out of her eyes she looked back to me. She walked over to my bed and sat down, patting the space beside her I sat next to her, "Okay, what I'm about to tell you can't leave this room. Are you all right with that?"
I nodded, "Of course, Jo, you can trust me." I said, taking her hand. I was feeling pretty confident that we might be making out again very shortly, stepmom or no, I really wanted that.
