What am I doing? I thought to myself as I went to grab one of the medical cups. Then I thought, I’m going to watch my son jerk off in his room! How sexy! How perverse! How depraved! How… wrong! I thought as I realized my lust was taking over my thoughts again. But I have to do this or I’m a bad mom! And if I do this I’m a bad mom anyway! AH!
I felt so conflicted but I went back to Rob’s room. When I walked back in the room, Pam was talking to Rob about something normal as if he wasn’t standing naked with a humongous erection sticking out of his midsection.
“Okay Rob, we’re ready.” I said as I placed the cup on the floor in front of him.
“Wait? What are you doing?” Pam asked as I placed the cup on the ground.
“Rob cums a lot,” I said, too horny to censor myself. “And only a little cum needs to land in the cup. This is how we were doing it in the shower when he jerked his big cock before you came home from vacation.”
Pam was giving me a funny look. I feel like I was practically drooling standing there with Rob’s hard dick a few feet away from me. Pam shrugged and said to Rob, “okay, Robbie, jerk that ‘big cock’ of yours.” Mimicking how I talked when she described my son’s penis, making me scowl.
Rob started jerking his cock automatically faster than a jackhammer, “Rob! Stop!”
“Huh? What?” He said as he stopped jerking his thick meat.
“You have to slow stroke, remember?” I explained.
“Sorry, but it’s like I said before. As soon as I start my whole brain just wants to cum and that’s all I can think about.” Rob looked in my eyes, pleading, “could you help me again, Mom?”
I blinked, I felt my pussy throb, I asked, “is that an order, son?”
“Umm…uh?” Rob said obviously unsure what I wanted. I mean, I was unsure what I wanted in that moment as well…
Pam stepped between us, “no, you’re Mom isn’t helping you again. You know she loses all control around you.”
“I knew that?” Rob said even though I told him a few days ago, but I guess when all the blood is in his cock, one thicker and longer than my forearm, there wasn’t a lot left for his brain and he couldn’t remember things so well.
“Yes,” Pam said, “and your Mom isn’t going to do that. So I’ll have to.”
“What?!” I said, not loudly, just angrily, “you most certainly are not!” I was very stern, but really I was jealously thinking, if I can’t jerk Rob off, Pam shouldn’t be allowed to either!
“Nancy,” Pam said to me, “obviously, somebody has to do it since Rob can’t do it on his own without losing complete control. It’s part of his condition and I’m sure if you called Dr. Xania she would tell you the exact same thing.”
I wasn’t sure about that and was thinking about giving her a call even though it was still extremely early, but I was then worried that Violet or Alice might wake up to catch us. “Fine,” I said after a moment, “But this will be the only time because it’s Rob’s job to find a girlfriend today.”
Pam
I smiled at Nancy, then I smiled at Rob. Then I got on my knees and gripped that amazingly huge cock in both my hands.
“Oh my God!” I said as I gripped the massive thing and started slowly stroking it as was prescribed by the doctor. “This is such an amazing cock! God, what if it was in my mouth! Or my pussy! Or my asshole! I wanted to fuck it! I want to suck it! I want-”
That was when Rob started cumming, I had a feeling my dirty speech would have an effect on him. But something I didn’t expect was his cum getting in my mouth. I closed my mouth as Rob proceeded to cover my face in cum, and I tasted him. “MMmm,” I moaned, it was the best spunk I think I’ve ever tasted, and as I swallowed it I felt my pussy pulse, I felt my body getting hornier by the second, and then, without even thinking about it. I put my mouth over Rob’s cockhead and started sucking the sperm directly out of it.
“WHAT THE FUCK!?” I heard Nancy shout but I didn’t care. And as I swallowed, getting hornier and hornier as I did so. I started ripping my clothes off, fully intent to fuck Rob as soon as he finished cumming down my throat, but Nancy suddenly tackled me.
My mouth came off Rob’s cock as he kept cumming and cumming all over both of us. Nancy was livid and yelling even as Rob’s sperm got all over her back and legs, “What the fuck are you doing?! The reason you did that was so that I wouldn’t and you’re just as bad as I am!”
“Nancy, stop, we’re getting cum-covered…” I pointed out as I struggled, feeling like we were teenagers wrestling in our room again, but this time with a huge cock spurting semen all over both of us.
Nancy looked down at us then, noticing all the sperm clinging to our bodies, she looked up at Rob, who was no longer cumming but his cock was still rock hard. Nancy groaned in frustration, she grabbed the cup from the ground, which actually did have a little sperm in it even though both me and my sister’s bodies had been in the way. She grabbed it and stormed out of the room.
I was still horny enough that I considered for a brief moment fucking Rob anyway, but knew that would only piss Nancy off further as I started moaning as I fucked him and there was no way I could hold back on that amazingly large dick. I just told Rob to go take a shower, and went back to my house, walking through Nancy’s kitchen with sperm all over my face gave me a naughty thrill, but Alice and Violet were still asleep then and didn’t catch me.
After I calmed down in the shower (by finger fucking my horny pussy until I came), I saw exactly how Nancy kept losing all control around her son. I had almost done the exact same thing after all. But it also made me think that if I pushed Rob to be more confident, Nancy would be powerless to resist him and would be able to nothing but leave that horrible sex-free cage she’s locked herself. I began scheming on what I could do with Rob after school that day…
Rob
I didn’t know what really happened. I get so lost when I’m jerking off and cumming that I was only vaguely aware that Mom tackled Pam as I came on both of them and I honestly didn’t know my cock had been in Aunt Pam’s mouth for any length of time at all. My pleasure was that great.
Anyway, the first day of school wasn’t really that interesting. I took a shower and played video games for the rest of the morning. I heard as Violet and Alice got up and took their showers as well. And Mom went downstairs and made breakfast. We all ate together, Mom acted like nothing was different, and Mom left for work just before the bus got there.
We rode a smaller bus than what others might have to their high school. But it was just because there’s only a few students from the outskirts of the city that needed to be taken to the school. It’s basically me and my two sisters. Jade, my best friend who was also friends with Violet, and Luna, who was Alice’s best friend.
There might have been one or two other students who road our bus too but I don’t remember as we didn’t talk to them.
I had planned on sitting with Jade and maybe asking her to be my girlfriend and then explaining how I needed to cum twice a day and maybe she could help with that… Or something. But it just made me nervous before I sat down next to her. And then Violet sat with her before I could and they talked about sports on the trip to school instead. Then Alice and Luna made fun of me the whole way there. But, truthfully, Luna had always been kind of a bully to me. It probably helps that I don’t fight back. Neither of my sisters told their friends about my condition though, which I was grateful for.
