She looked so hot. Her little pony tail bouncing about as she fucked me with her sloppy mouth. I couldn’t hold on much longer. I decided I wanted to make a mess on her. I wanted to see her drenched in her brother’s cum.
The image of my sister, the bangin’ hot slut that invades my fantasies on a nightly basis, covered in my cum passed through my mind and I quickly reached the point of no return. Just as I prepared to pull my cock from her mouth and hose her down with my nut, my door opened.
“Hey Jackie”. Jenn bolted up right and we both froze. “Oh… Didn’t realize you were in here too Jenn.”
I was grateful that my sister’s body was between my cock and the door, because I was cresting hard. Jenn’s hand was still wrapped around my cock and she held it perfectly still, virtually edging me, preventing my orgasm from subsiding. Her other hand still gently moving between her legs, but just barely.
“Oh mom. We’re just talking” Jenn’s voice quivered as she glanced over her shoulder. Her hand tightened on my cock, further pressing me to the edge.
I moaned pleadingly. I was in pain. She knew it. She looked back over to me apologetically, asking me with her eyes to hold it in. Her own body quivering gently in front of me.
“So nice to see you two bonding finally” My mom chirped and opened the door a bit wider.
I couldn’t hold it. I thrusted my hips forward just enough to slide my cock through my sister’s slick fist merely an inch, but enough to ignite the smoldering orgasm that was building up in my dick. Her body jerked almost imperceptibly and her eyes rolled back. Her tits jiggled in her low-cut nightshirt. I could hear the faint sounds of her pussy ejecting the slightest bit of cum into her panties and over her hand as her orgasm took her body.
“Ugh. Jack…” She grunted at me, clearly loud enough for mom to hear.
“Hmm?” Mom inquired.
“…Has had loads of… Patience for me lately.” She quickly saved herself in time to continue submitting to her orgasm while mom unknowingly watched her little girl cum climax in front of her. Her pussy began to unleash multiple squirts of cum into her underwear while she rode it out and shook gently with each blissful wave of climactic glory.
“You kids are sweet.” Mom said proudly.
I leaned slightly to the side and peered around my sister to see my mom off, her pretty smile beaming back at me. Her cum-soaked towel was tightly wrapped around her, barely high enough to cover her nipples, her immense cleavage spilling from the top of the towel.
I stared at my mom’s tits while my cock began forcefully squirting hot ropes of cum straight into my sister’s face. I imperceptibly humped my hips forward into my sister’s hand with each thick stream of nut. Into her mouth, across her cheeks, down her neck and across her tits pushing through the deep v-neck of her shirt.
“Well sweet dreams you two” Mom softly latched the door behind her. Her last words just as chipper and light-hearted as the first. Her eyes must have not had time to adjust to the darkness. At least not enough to watch her kids cum for each other.
As soon as the door shut, Jenn hungrily slurped at the end of my cock, pulling the last few waves of my orgasm from my cock and extending my climax several more seconds.
“Holy fuck” I whispered. Jenn sat up and had to swallow several times to clear out her mouth and throat.
“You think she suspected anything?” Jenn asked hastily as she licked my cum from her lips and around her mouth.
“She didn’t seem to” I responded. Jenn continued licking cum from her fingers and massaged the rest into her face.
“Amber was right…” She mumbled. “It absorbs way better when it’s fresh and warm”.
I could sit and watch my sister rub my cum on herself all night, but I had to hit the sack.
“Just let me know… I’ll let you take it from my cock any time” I joked. At least I thought I joked, but she looked at me seriously, eyebrows raised.
“Don’t make any promises you can’t keep”
She finished cleaning herself up and dragged my comforter out of my room to the laundry that she’d soaked with cum while mom watched. We didn’t discuss what’d just happened. I wasn’t sure how it would change our relationship, but I was really hoping to make good on that last exchange. I’d never cum that hard before and I was hoping it wasn’t the last time.
Now… How to deal with these new fucked up feelings I had for my mom… That would be another story.
