“You can’t Josh. Mom would kill you.”
“Well, you won’t let me cum in you, and Mom won’t know by the time she wakes up.” I reasoned, “Plus, there’s less chance that I’ll get her pregnant.” I sped up my thrusts as I started pounding our mother’s cunt.
“You’re fucking her too hard. She’ll know something was up in the morning.” Stacie warned.
I didn’t slow down, “I don’t care anymore. I’m fucking my mother’s pussy. I’m gonna cum in my own Mom!”
“No, wait! Look, I’ll let you cum in me, okay. Just don’t do it in Mom. Deal?” Stacie bargained.
I slowed my pace, “Really?”
“Yeah, I’ll risk it.” Stacie said, “If Mom realizes we fucked her it could be worse than me randomly winding up pregnant. I could just blame it on a one night stand.”
I took a few more strokes in my mother before I pulled out. Cumming in Mom would’ve been great but there was nothing I wanted more than to fill Stacie’s pussy with my load. She laid down beside Mom and spread her legs in front of me. I lined myself up between her legs and entered her again. It felt like a whole new world. Mom’s pussy had heat and warmth to it, but Stacie’s pussy was on fire. It gripped me like I never left and instantly soaked me in its juices. I pounded Stacie hard, while we kissed next to our sleeping mother. My cock hitting the depths of her walls, Stacie didn’t restrain her moans this time, screaming on each thrust as I fucked her hard, her pussy dripping with sopping wetness that engulfed me. Our sex was thunderous, hard and aggressive. We threw caution to the wind as we were both nearing orgasm.
“Fuck me, big brother. Fuck your sister’s pussy hard.” Stacie moaned.
“Oh fuck yeah sis. Make me cum. Make me cum inside you.”
“Yeah Cum inside me big brother. Fill my little pussy up. “
“Oh shiiiiiiit.” I screamed as my body tensed and I buried my cock to the hilt in my sister and shot rope after rope of hot cum deep inside her. Stacie’s legs locked around my waist as her own orgasm took over her. She shuddered underneath me and her eyes rolled to the back of her head. She arched her back as her orgasm ran through her. My body locked in place as I emptied my sack of all its stored up semen. I twitched several times as the last bits of my orgasm left my cock head and into my sister’s womb. We made out for a few minutes afterward until the trills of our seemingly never-ending climaxes finally subsided.
“Yeah, Mom definitely would’ve noticed that.” Stacie finally commented. We shared a laugh.
“Yeah, probably.” I said, “But I’m glad I got to do it with you instead.”
“Me too.” Stacie responded, “But I’ve never cum like that before. I think you cumming inside me helps increase my orgasm.”
“Good, so…?” I questioned.
Stacie chuckled to herself and smiled shyly, “Yes, you can do it again.”
Present Day
“And that’s how it started,” I said with my head down, staring at our dining room table. Mom came back with Stacie from the hospital. She questioned us both about how long I’d been cumming inside my sister. Both Stacie and I decided to come clean. Mom’s face had gone from furiously angry to unsure and now to uncharacteristically quiet. Her mouth was partially open as she struggled to find the words.
“Oh..my..god.” She finally choked out, “You…fucked me?” Mom asked.
We nodded. Both of our heads down.
“I…can’t. I just can’t.” Mom got up from the table and stormed to her room.
“What should we do?” Stacie asked.
“I don’t know. I just know she doesn’t want to talk to us right now.” I said.
We spent the rest of the day cleaning up the house, cooking dinner, and staying out of each other’s way. Mom had taken Stacie to the doctor to see if she was pregnant. Luckily she wasn’t, so Mom immediately put her on birth control.
“She wasn’t that mad, but she was really concerned that you had knocked me up,” Stacie said.
Mom stayed in her room for the rest of the night. Stacie and I decided it was best not to have sex for a while at least until her birth control kicked in and especially to see how Mom was gonna be around us.
We stayed up late watching movies and talking about our relationship until about midnight when Stacie got up to go to sleep. I followed after her but wanted to make one check on Mom before I did.
I knocked on her door, but there was no answer. I turned the knob and to my surprise it was open. I walked in and found Mom on her bed, asleep and completely naked. On her nightstand was her Ambien bottle, and a note that read, “Finish what you started.” I looked at the note stunned. I turned it over to see if it was a joke, but on the back was something else written, “P.S – Cum inside me this time.”
I put the note down, locked her door and started to undress.
