There was a light tap at the door. "Jay? Di? May I come in?"
Di leapt to her feet as a look of shear panic spread across her flushed face, eyes wide with fright. She quickly raised her right hand and arm to her chest partially covering her small breasts. Her left hand clamped over her crotch and pussy lips.
My heart leapt and pounded in my chest. In addition to just cumming, I was in fight or flight mode from the huge surge of adrenalin that hit my blood stream when our Mom knocked on the bedroom door.
I grabbed the towel resting against my right hip and furiously wiped at my jizz streaked stomach and chest. My softening cock continued to ooze white semen onto my thigh; it formed an enlarging wet stain where it dribbled off my thigh onto the sheet.
-OK, time for a brief recap. Di, my gorgeous sister, and I, as you may or may not remember had just finished a mutual masturbation session. I was naked on my bed, having just ejaculated cum all over my chest and abdomen. Di was equally naked on a chair at the foot of my bed with her feet propped up on my mattress, knees bent and separated. Her right hand rested on her pubic mound; the tip of her middle finger lingered inside her vagina above her wrinkled, moist, rosebud of an anus.
OK, enough recap, back to the story.-
"Oh my god!" Di mouthed at me.
"Shit!" I mouthed to her.
"What do we do?" she mouthed back.
"We're fucked!" I mouthed right back, still wiping furiously at the cooling cum splattered on my body.
"Oh, never mind. I just remembered where I put it. Don't stay up too late. Di, be sure to hang your suit up or put it in the laundry room. Please don't throw it on the bathroom floor. Good night. I'm going to bed," Mom interjected unknowingly into our panicked yet silent communication.
"Goodnight Mom," I said looking at Di with a huge smile of nervous relief spreading across my face. "Love you."
"Goodnight Mom," Di squeaked out. Then more strongly, "Love you Mom."
"Love you both bunches," Mom replied distantly from down the hall.
"Whew. That was close," Di whispered as she dropped her hands to her sides, chest heaving, her little boobs jiggled up and down with each deep breath.
"No kidding. I thought I was going to have a heart attack. My heart is still going to town," I whispered back and chuckled.
"Not funny Jay," Di said with a serious look of concern on her face. "Jesus, that scared the crap out of me."
"Me too, but all's well that ends well."
"Yeah, I guess," Di said as she stood up and dropped her hands. She smiled as she watched me continue to wipe cum off my body.
"Yeah, you looked pretty panicked trying to wipe up that huge load. My, you do cum a lot."
I admired Di's body as she stood at the foot of the bed watching me wipe my chest. She really is beautiful. Short brunette haircut that outlines her cute face, brown eyes with long lashes, small straight nose, full lips that were always ready to smile and reveal perfect white teeth, delicate neck, slim body wrapped in flawless skin, small tanned breasts with perky nipples, flat stomach that curved down to her dark and neatly trimmed bush, and long lithely muscled arms and legs. God she's gorgeous, and sexy. Yes, very, very sexy.
My cock twitched.
Di laughed. "I saw that."
"What?" I asked feeling like I was actually blushing.
"Looking. You sure gave me a good once over. Do you like what you see?" she asked striking a model's pose, in partial profile with hands on her hips and her ass thrown slightly back.
"I looked her over again enjoying the profile of her breasts and erect nipples, and the smooth curve of her tight firm ass."
"Yes."
"Yes what?"
"I like what I see very much."
My cock twitched again.
The movement drew her eyes down to my cock.
"Oh my, you are easily aroused aren't you? Does your little sister turn you on?" she asked as she raised her hands, cupped her breasts and tweaked her nipples.
