“Great, she left me standing here, with a hard-on. What a tease!” I thought, as I put boxers on to sleep in. I eat my cake and drink a glass of milk. When done, I take the glass and dish down to the kitchen. As I hit the bottom stair, I notice Mom and Dad making out on the couch. They are heavily into kissing, with mom’s hands busy under the blanket. I quietly put my dish in the sink and find a better view. I watch as the blanket bounces up and down, Dad’s head laying back with his eyes closed. Mom leans her head on his shoulder and whispers in his ear. She then kisses his neck, she lowers her head down, kissing along the way. Eventually her head disappears under the blanket. The bouncing lump in the blanket is bigger now. It gradually speeds up and Dad lowers his hands to her head and stops it. Moments later Mom’s head pops out and she wipes the corners of her mouth. They kiss deeply, as Dad’s hands sneak up under her shirt and find Mom’s breast. I fish my hard cock out of the fly in my boxers and start to stroke watching my dad and mom.
“What are we watching?” my sister asks, whispering in my ear. I almost cum, right there, from the shock.
“Mom gave him a blowjob, and now he is about to return the favor.” I glance at her and notice what she is wearing. She has on sexy pajamas. A crop top that barely covers her tits and booty shorts that seem to have crawled up her ass, leaving a beautiful camel toe. Her nipples are pointing out as she reaches out a hand and takes hold of my cock. Mom lays down on the couch as Dad pulls off her shorts and puts them on the floor beside them. He pulls up her shirt freeing mom’s wonderful breast. He licks them both, taking time to suckle at her nipples. Mom’s face smiles and we can hear her moan from over here. He licks down her chest and stomach, stopping just above her mound. He slides a finger inside her, and we watch her as she lifts her hips trying to get her pussy up to Dad’s face. Dad lowers his mouth down to her bush, licking around until he finds Mom’s love button. “Oh… Yes!” She says softly. “Eat me. Eat me now!” Mom’s hips lower with Dad’s mouth until her tight ass is back down on the couch. Mom puts one leg on the back of the couch, the other on the floor. She is wide open for Dad’s mouth to please her.
“MMMmmm look at him eat that pussy.” My sister whispers as she lifts a hand up under her top, squeezing her breast and pinching at her nipple. Her other hand now stroking my cock slowly. I glance back at Mom to see her running her hands through Dad’s hair. I can see her hips grinding up and down against Dad’s face. Her mouth is wide open, and we can hear her moaning out.
“I think she is about to…” Mom pulls Dad’s face tight against her wet lips, her eyes roll back in her head, and her hips shake. “OOOOhhhhh, MMMmmm… Yes!” She groans.
“Orgasm!” My sister finishes. Her hand now down her shorts, rubbing fast and hard against her own pussy. She has a death grip on my cock. I watch her as her mouth opens, her eyes close, and she squats down a little as she shakes. I reach up and pinch one of her nipples and she closes her mouth and bites her lower lip.
Mom and Dad begin to get dressed. My sister and I take this as our cue to leave. We sneak back up the stairs, hoping we aren’t seen. My sister walks past my room and enters hers. She looks back at me before entering, looks me up and down again, blows me a kiss, then disappears into her room. I’m left here again with a hard-on.
I turn on the computer monitor, and on the screen is a file marked top secret. I’ve never seen this file before so obviously my sister has been on my computer again. My curiosity gets the best of me, so I open the folder. There’s my letter, corrected, and another folder that is password locked. Below it is a clue, “To open me up, you only need to know my date of birth. You get three chances.” I enter my sister’s birthday… “STRIKE ONE” appears. I laugh. I enter my birthday… “STRIKE TWO” appears. Now I’m a little confused. As all men know, when the blood from your upper head is in your lower head it’s hard! To think. I think about what I’m trying to do… open a new folder… a folder born today. I enter today’s date and the file opens. I’ve never given my sister credit for being this smart.
There in this file are four pic files and a video. Each is labeled with open first, open second, and so on. I wondered what my sister could have loaded on here. I open the first one…
A picture of my sister in those sexy PJs laying on my bed appears. Her legs spread open, with her camel toe prevalent. Her nipples are poking out and she is blowing a kiss at the camera. I click on the second one…
A picture of my sister topless. She moved the camera to give a nice close up. I can see the bumps around her hardened nipples, on the edge of her areolas. I click on the third one…
A picture of my sister’s ass in the air. She is naked with her hands holding her cheeks open. Her asshole is puckered closed, but her pussy is wide open… glistening. I begin to stroke my cock still hard from our time in the kitchen. I imagine my cock entering my sister’s glistening lips. I click on number four.
A picture of my sister, spread eagle with her fingers inside her pussy. Her tits appear to be shaking as she is masturbating here on my bed. I feel my balls begin to tighten. I’m close to finally blowing my load for the third time today. I click on the last one… It’s labeled enjoy this.
A video opens and begins to auto play. My sister has her arms squeezing her breasts together… she is sucking on her nipples as she drives two fingers deep in her sopping wet twat. Her other hand is at her asshole. She has one finger deep in her ass. Her hips are shaking as her fingers drive in and out of her open holes. Her eyes roll back, and I hear her…
“MMMmmm… Fuck me, Sean. Make me cum… YES, YES, YES!” She begins to convulse. Her mouth open she lets out a few “UNGH… UNGH… MMMmmm… YES SEAN. Give me that huge cock!” Then she collapses on the bed. She waits a minute, then pulls out a pair of purple panties. She rubs her ass and pussy with them then shoves them under my pillow. I stroke faster and reach under the pillow. I grab her panties and put them to my nose. I can smell her musky scent. I stick out my tongue and lick… her pussy juice is still fresh, tangy with a hint of urine. I imagine that wet pussy riding my face. My tongue deep inside her, her mouth on my cock, my cock in her throat. She starts to swallow and… my cock explodes. My cum covers my chest, stomach, and abdomen. Finally! I use her panties to wipe it up, soaking them with my scent. I sneak next door and enter her room. She is lying in bed naked, asleep. I slip the panties under her pillow and sneak back out of her room.
In the morning I wake to the sound of moans coming from my sister’s room. I get up and listen at the wall for a minute, then head to the bathroom. I get my morning routine done and head downstairs. Mom and Dad were gone already. Technically my sister and I were alone, but I needed to get to school early. I needed to make sure Brad was still okay with me and his mom. If he is, maybe we can do it again. Mom left us a note, “Sweetie, good luck with your Chemistry Test. I know you can do well. Remember the order of the electron cloud. Honey, have fun at the frat party. Invite Tami home if she drinks too much. Your Dad and I will be out late ourselves, maybe all night. Don’t wait up.” My sister walks down the stairs, a towel wrapped around her head, nothing else. She walks to the fridge, bends over to grab an orange from the fruit drawer, and shakes her ass at me.
