Iris was confused about why she didn't have a problem with agreeing to teach him about sex. But it just felt right to her, and she was okay with it; she slid her hand into Jason's pants, and her eyes widened as she spoke. "You have grown up very well, Jason. You have to be the biggest man I have touched, and this is worth more than I thought it would. Please lay down for me, will you." Iris said, and I did as she asked. If I was going to play the naive boy, I might as well stick to it.
"Let your big sister Iris help her new little brother with his problem." She said while my head lay on her lap, and her hand moved to my shorts, pulling them down along with my underwear. As my cock popped out, the three girls gasped, looking at it as Iris's eyes lit up with desire. "Just stay still. I will walk you through how to get your penis to relax." She said, smiling as her hand took hold of my cock moving it up and down as I looked up from her lap.
"You have a fine cock, Jason; it's the best I have ever seen," Iris said while starting to blush as she thought about how it would feel putting it inside her pussy. She had just broken up with her boyfriend and hadn't had sex in the last month; now, this fantastic cock showed up in front of her, and she wanted a piece of it as she lifted her shirt and started to talk. "See, boys, get hard when they are near a girl they find attractive. Do you find your Big Sister Iris attractive, Jason?" She asked as she started to bite her lip.
"Big Sister Iris is really beautiful," I said, making a fake moan to turn her on. Making her smile as she moved the hand not on my cock to take her shirt off and put it on the sofa. "Iris, I think I should be the one to help my brother," Sofia said, standing up. "Come on, Sofia, you know you can't do that. I should be the one to help him learn about his body." Iris said. "Why not all of us?" Evelyn said as she took off her top. Making the other two think for a moment and nod.
"Jason, we three are going to guide you. Why don't we go up to my room? That way, we can teach you better." Sofia said while removing her shirt, letting her bra-covered breast pop out. I nodded to her, making her smile as she pulled me up by my hand and helped me take my pants off. As she brought her face closer to my cock I could feel her breath on it, making it jump. I couldn't wait any longer and rubbed it on her cheek, making her look up at me. "Sofia, can you put it inside your mouth,h please," I said naively, making her smirk as she moved her mouth to the tip and kissed it.
"Let your big sister help you." She said before putting my cock into her mouth, taking it slowly inside her mouth as I moaned, looking at her as her eyes looked up at me. "Sister, your mouth feels amazing. I want to do this more often, Sofia." I moaned, moving my hand to her head and running my fingers through her hair. Then, I pushed her head down as she placed her hands on my thighs, letting me push further into her mouth. "Sofia, suck harder," I asked, looking into her eyes as she started to suck harder while moving her head faster to meet my demands.
Sofia started to gag on her brother's cock, but it turned her on so much that she wanted to gag more on his massive cock. She thought to herself, how could a twelve-year-old be so fucking big and taste so good in her mouth that she started to move a hand down to her skirt, sliding it under and into her panties as her fingers rub hard onto her clit, making her pussy throb for this cock inside her mouth. She started to feel his cock jump in her mouth, and this made her happy as her brother was about to cum, and she wanted to drink it.
"Sister, something is coming; I don't know what to do," I said naively as she reached around my hips and pulled my hips forward, making sure I didn't pull out as I started to cum inside her mouth. She gulped my cum down with her eyes wide open, enjoying the taste and feel of the thick jelly-like cum sliding down her throat before I finally stopped cumming, and she popped my cock out of her mouth and started to jerk me off. Making it harden again. She smiled and spoke.
"Shall we go to my room now? I have much to teach you, dear brother." She said seductively as she started to rub my cock harder with her hand. "Yes, sister, I want to learn more from you three," I said sheepishly as this made her smile and her friends smile. They dragged me off to her room. When we got there, they pushed me onto the bed and started to take off the rest of their clothing.
Iris and Evelyn lay next to me with their breast next to my head as Sofia crawled in between my legs as started to lick my cock again. She wanted to make it completely hard again as she fingered her pussy as she spoke. "Jason, do you want to have sex with us? I want to have sex with you because I love you a lot." She said while licking my cock I looked down at her, and she looked up at me. "I have to have sex with you, sister," I said sheepishly, playing the role of the naive brother to the T.
Sofia smiled brightly as I agreed, making her extremely happy as she crawled up and took her place above my cock as she rubbed the head on her pussy, moaning. "Jason, do you feel how wet your sister is? That means I am ready to take your cock inside me; make sure that a girl is at least this wet before putting your massive cock inside them, as it could hurt her." She explained as I nodded my head in understanding. My sister lowered her hips as I felt the head of my cock push open her pussy lips. She moaned.
"You are so thick and big, Jason; you're the best I have ever had. I want to have sex with you more!" She yelled that last part as she finished taking the rest of my cock inside her and lifted her hips slowly, riding me. Her D-cup size breast swayed with her movements as she looked down, seeing me looking at her breast and smiling. "Do you want to play with my breast from now on? I don't mind you coming to my room from now on if you ever feel the need to relax your amazing cock."
I nodded rapidly, making her smile as she moved faster and spoke, "I want you to release the stuff you made me swallow last time into my pussy. Can you do that for me, Jason? Your sister would love to feel that thick, hot stuff of yours inside me, please." She said while placing one hand on my chest and one behind her on the bed while moving her hips forward and backward as she lifted her hips. Shit, this felt amazing as I turned my head and clamped my mouth onto Iris's hard nipple and placed my hands on Sofia's thighs as I started to lift my hips.
"Oh, my brother wants to pound my pussy now? I don't mind; thrust your thick cock into my pussy and make me cum too." Sofia moaned as I sped up, thrusting into her with great fervor. "Jason, you're a natural at this! Yes, fuck your sister like a man!" She moaned as she moved faster while I thrust inside her making her start to clamp down on my cock, telling me she was close to cumming, and so was I. "Jason! I am going to cum! I want you to bust a thick load of your jizz inside me!" She screamed as I thrust deep into her pushing into her womb and pumped my hot load of cum inside it.
"FUCK! MY BROTHER IS PUMPING HIS HOT CUM INTO MY WOMB! THIS IS AMAZING, THE BEST SEX I HAVE EVER HAD!" Sofia screamed at the top of her lungs as she fell forward when she stopped cumming with her breast on my face. As she was sweating, I started to lick it off her breast, and she moaned, picking herself up as she looked down from above me and leaned down to kiss me.
"I think I won't be able to get sex with you out of my mind," Sofia said after pulling her mouth away and getting off my cock as I felt a warm sucking force on my cock. I looked down to see Iris sucking my cock clean and pulling it out of her mouth as she spoke.
"It's my turn now, my dear little brother." She said with a seductive smile.
