Twin sister and I pull our vulnerable mom into our room

My mom found out me and my twin sister were having sex, but we lured her in instead.

Me and my twin sister are 16 and we live with our 40 year old single mom. We didn’t have much so me and my sister still shared a room. This had the fortunate side effect of us being really close. It started two years ago when we would masturbate with each other, evolving into use fucking every chance we got. As we develop we couldn’t stop ourselves, I got pretty nice dick (at least I’m told) and my sister developed huge d cup breast and sexy hips that drove all the boys mad. My mom and sister both had really awful periods so they both were on birth control to regulate it. This was perfect for us because I would pump her full of cum every time mom worked late. Our best moment is when we almost got caught in the shower together and she kept sucking my dick while I was talking with mom.

We hadn’t done anything in a week cause mom didn’t go out. Finally she said she was going out with friends and would be back later. She was wearing this yellow floral sundress and I’ll admit I stared for a bit. But I was quickly reminded of the prize in front of me as I immediately went to the room with my sister. We passionately kissed as we took off our clothes. She licked her hand, showing me her long pointed tongue. She used the saliva to start stroking my dick. Her soft hand made me weak as she used her other hand to grab my head and tilt it so she could suck on my exposed neck. I felt her tongue run up and down it as her hand tried to wring out my dick. After a bit I managed to regain control by turning her around and eating her out from behind her moans filled the room as she spread her fat ass so I could get every inch. Once her pussy started gushing juices I rubbed my tip on her entrance. “Wait” she said as she pulled away. She flipped around and sat on the side of the bed. She spread her legs and held her arms out. I embraced her as I pushed my cock deep inside. Her drawn out moan filling the room. I slowly pumped her so her moans would stretch out into deep sounds of pleasure next to my ear. I felt my dick about to explode, “I’m going to cum” I whispered in her ear. She locked her legs around my waist and pulled me into a deep hug. I pushed in deep and filled every inch of her pussy with my cum. I sat there with my cum pouring out for a bit before she let me go and I was able to pull out.

She dropped down and started licking my dick covered in our juices. “Stop or I’m going to cum to quickly.” I told her as I felt her tongue swirl around my tip. She popped it out of her mouth “ I got to get it ready for mom” she said cheerfully. I was ever confused till I hear something behind me. It was mom peeking through a crack in the door! I froze as we locked eyes with each other, my sister still lazily stroking my dick. “Come out now, I know you want to” she said, beckoning her with a single finger. As the door opened I saw my mom’s face beet red with embarrassment. She looked down on the floor as she approached. Sis explained that a bit ago when mom was tipsy she talked about how she had been so pent up since dad left, and she needed some release soon. My sister mentioned that she had a new boyfriend that might help. My mom tired to refuse but was pressured into agreeing to watch them one night and see what happened. She then had mom leave to “meet friends” while she actually sneaked around back, where she heard the moans and assumed it was sis and her boyfriend. When she saw us she froze, but couldn’t bring herself to say anything. “So now we are going to help mom get out all that stress” my sister said, mom tried to refute “no stop I can’t, not with my son I-I-“, my sister interrupted “who said it was only going to be him” in a disappointed tone as she quickly moved behind mom and groped her tits. “ I wanted to see what it was like with another woman” I saw her start fondeling moms body. The sundress gave no protection as my sister groped every part she could. Mom face flushed again as she twitched with every grab, she bit her lip to stop herself from making noise. My dick was as hard as stone, I wouldn’t be surprised if it was longer than usual. “ I saw you touching yourself already, stop hiding” my sister said as she lifted up her dress, showing moms soaking wet pussy, her juices dripped down her thighs. “ just let it happen already”, my sister said as she slowly pushed mom down to her knees in front of me. “ just open your mouth and enjoy.” My sister said as she sat behind her, she used her hand to open up her mouth. I could see her tongue start to shake as if switching from accepting to rejecting. Was I about to do this, do it with my mom. I already crossed taboos with my sister but this feels different. I looked into her eyes, they were desperate, to afraid to ask but too needing to refuse. I slowly put my tip in her mouth, I saw her eyes twitch with anticipation. “ let me help you out” my sister said as she slowly pushed her head onto my cock.

I couldn’t hold back. Her blowjob was so different from my sisters. Maybe it was the clumsy way her tongue tried to move around my dick, or maybe it was my sister moving her head for her, biting her lip as she was cheek to cheek with my moms face. I started to move, pushing my dick deep down her throat. Every time I pulled it out she gasped for air, drool dripping down her chin. She didn’t resist, letting my dick fill her mouth. I felt my shot coming, and my sister did too cause she pushed mom’s head to take my dick all the way. I shot my thick load deep down her throat, her chocking sounds made it so much better. Once I was on I pulled out. She started gasping for air, some cum dripping on her chin. “Don’t let it go to waist” my sister said before she started licking her chin clean. The face fuck must have shut off mom’s brain cause she was in a daze. My sister finished off mom with a quick kiss before she got up and layed on the bed. She spread her legs and patted her hips. “You should do me next, got to make it fair.” Mom had given up on struggling, she got up and layed in front of her. She started eating my sister out vigorously, like a starving dog. I watched her for a bit before my eyes wandered to my moms exposed ass, it was bigger than my sisters. I must have started for a while cause I herd my sister cough and when I looked at her she was giving me the sex hand-sign. Mom was too busy gobbling up my sister to notice. I got behind her, she was laying down flat, my sister softly moaned as I got above mom. She tried to look back but my sister grabbed her head and pushed her down. “ you already knew this would happen, don’t worry, we’re experts.” I started to rub my tip against her pussy, she was already twitching like crazy with just that. I slowly pushed my tip in, I heard her muffled moan as I sunk deep inside, my weight fully on her. She was so wet I was gliding through, but she was still so tight. It was nothing like my sisters, hers was like constant pressure trying to crush my dick, mom was like a bunch of parts squeezing me in different places, like it was trying to milk my cock. I couldn’t stop myself from pumping like a mad man. Her barely contained screames showed how log she waited. I saw my sister was getting close so I pushed hard. I poured my strength into fucking this repressed milfs pussy. I pushed in deep as I let my cum fill her. He pussy was twitching like crazy as her and my sister let out huge moans.

For the rest of the night we fucked like animals. I fucked both of them. The gave me a double blowjob and titty fuck. I even got a rim and blowjob at the same time. Once we finished we both cuddled our mom from both sides. This was going to be a great time.
