Erotica: A tale of two sisters

A sleepwalk

I awoke in the middle of the night one night to the pleasure of my wife's naked behind pressed against my bare stomach. By my count, I has felt her orgasm three times during our bedtime lovemaking and she was sleeping soundly. I on the other hand was feeling the signs of arousal starting again. I didn't want to disturb Sarah as she had started having trouble sleeping. I got up, thinking I may have to get my laptop and take care of things myself to get back to sleep.

Walking out in the hall, I heard a noise coming from Chrissy's room. The door was open and saw the outline of her hips moving and heard a faint buzzing sound. My cock, still sticky with both Sarah's and my cum, immediately stiffened and my heart raced. I froze in place straining to see and hear more.

Suddenly I saw her freeze and instinctively pull the covers over her. We both stood frozen for a moment looking at each other in the darkness.

Finally she spoke up, "What....."

"Shhhhh....." I whispered, moving in to her room. I sat down on her bed and felt her hand move over me.

"Do you always walk around the house naked?"

"Only when I have been fucking your big sister then get woken up by my nanny getting herself off." I reached under the covers and felt only skin. "Do you always sleep naked?"

"Only when I hear my big sister screaming her husband's name and telling him to give it to her harder and fill her pussy with cum then I can't get to sleep."

"Maybe we should help each other get to sleep."

"We can't do that!"

"Why not?"

"Sarah is right there, not to mention Mad...."

"We'll be quiet."

I knew she wouldn't be able to resist so I slipped under the covers and kissed her as our bodies pressed together. When she vigorously returned my kiss and pushed tighter against me I knew it was on. I savored the feeling of her tongue in my mouth and her tits pressed against me. No preliminaries were needed as we were both beyond ready so I reached down to position my surging erection to her opening. She was soaking wet and I sank into her almost effortlessly as I rolled on top of her. We slowly and silently ground our hips together while our lips and tongues both struggled for supremacy against each other. My hands squeezed her ass and hers clutched my back as we both strained to pull ourselves even tighter together. I was pushing into her faster now but holding back to keep from making any noise loud enough to escape from the room. We kept kissing frantically, knowing it was the only way to keep ourselves from screaming out.

Finally our mouths broke apart and she whispered in my ear.

"I don't know if it's safe right now."

We both knew we were past the point of no return though. Her legs contradicted her words by wrapping around my waist so tightly that I couldn't get free even if I had wanted to. Her whole body jerked in a series of orgasm convulsions and she pressed her face into my shoulder to muffle a moan. I wanted to enjoy Chrissy's body to the fullest and I grabbed both of her tits and squeezed them together. I took one of her erect nipples in my mouth and swirled my tongue around it. I kept plunging into her as I enjoyed her tits and without warning a wave of pleasure overcame me and I felt a completely involuntary release. My post orgasmic twitching cock caused Chrissy to orgasm again around my cock and then we both relaxed into each other's arms and kissed deeply. We slowly kissed for a few minutes while we ran our hands over each other's bodies. I kept pushing my still semi hard erection into her warm cummy pussy.

My naked wife was still fast asleep when I slipped back into our bed. I pressed my bare chest into her bare back and my softening moist cock against her round ass. I reached around her and traced my fingers over her growing belly and tits and quickly fell asleep.

"Morning you guys."

Chrissy came out to the kitchen wearing a long nightshirt extending just past her waist and no sign of anything else. Her long blonde hair was a mess. I stole a glance and thought I could just see a glimpse of white crust on her inner thigh.
