I woke up a few hours later and had to blink and recall where I was and what was going on. In the faint light of my sister's bedroom, I could see Amy's blonde hair in front of my face. She was moaning softly and pressing her butt back against my hard cock. The covers had been pulled down, and I lifted my head slowly. Amy had pulled her shirt up.
Hope was once again moaning as she sucked on one of Amy's stiff nipples. I realized then what had awakened me. Amy had pulled my dick out of the front of my boxers. She had shed her panties, and now she was rubbing the head of my cock between her moist pussy lips. Hope saw my face, and she closed her eyes briefly before looking at my face expectantly.
She wanted me to act like I was asleep? I closed my eyes and carefully lowered my head back to the pillow. I realized I had been holding my breath, and tried to breathe evenly.
I heard Amy whisper, "Oh, he's so hard right now. It feels so big pressing against my wet pussy."
Hope moaned and released Amy's nipple. "Oh, you're so bad, Amy! He's my
little brother
."
"He's not so little anymore," Amy growled back.
I bit my lip and breathed out through my nose when I felt the head of my cock slide into Amy's wet pussy.
"Oh! He's inside me!" Amy hissed.
I heard Hope moaning softly as Amy pushed her head under the covers. I felt her hot breath on the shaft of my cock and my balls. Her breathing quickened, and I heard and felt her taking a whiff of Amy's wet pussy.
"Does that look hot?" Amy whispered. "Does your brother's cock look incredible stretching my pussy like that?" Amy held the base of my cock steady, and then she moved her hips so that just the head of my cock slid in and out of her. "How does that look?" she hissed. Then she groaned.
I felt the wet tip of my sister's tongue as she licked Amy's clit. Amy shifted her hips and her grip, and then I felt my sister's hot mouth taking in the head of my cock. "Oh, fuck!" Amy gasped. "That is so hot!"
Hope sucked my cock noisily for a few seconds before she reached up and pressed me back into Amy's pussy. Her hand reached around and she pressed my ass forward. I started pumping my hips forward, and Amy gasped as she lost her grip on the slippery shaft of my cock. It was buried inside her two strokes later. I moaned and thrust in and out of her tight, slippery channel.
My sister's head popped up out of the covers and she kissed Amy on the lips again. "You are so bad," Hope growled. Amy just panted as she came all over my invading dick. Hope snaked her hand down and teased Amy's clit, pushing her to a new level of climax. Her pussy spasmed and squeezed my dick.
It took all of my self-control not to come inside her right then. I groaned and "woke up" then, acting confused.
"Amy? What are you..." my hand slid down her side, stopping on her naked hip. "Where are your panties?"
"Oh, Daniel," she moaned, turning her head to kiss me on the mouth. "Please fuck me!"
Hope's eyes met mine then, and she nodded enthusiastically. I groaned and thrust into Amy's drenched pussy, and she moaned into my mouth. She was planting fluttering little kisses on my mouth and panting as I drove my hips forward and back.
"You guys look incredible," my sister breathed. Then she went back to noisily sucking Amy's nipples.
Amy cried out and shook like crazy when I came inside her. After that, I held her in my arms and kissed her. I fell asleep soon after.

We slept in and then lounged around the apartment in bathrobes as we enjoyed a late breakfast together. Eventually we had to get dressed and go to class, but everything had changed. We were so comfortable around each other. The tension of the previous day was gone.
Amy needed to head back to her apartment to change before class. She talked to us while she shed her robe and pulled on her clothes from the previous evening. It was only after she pulled the t-shirt over her head and turned to us that she realized we had watched her. She blushed slightly, but then shrugged it off and kissed us both before leaving.
"I have to work tonight," she said, "May I come over after that? It will be pretty late."
Hope said "Sure" at the same time I said, "Of course."
We did not have that much time after Amy left, so we talked in the shower. I told Hope that I had admitted to Amy that I would get hard when she and Colleen sat in my lap, and that I had fantasized about something happening. "Of course, we never actually
did
anything," I said with a grin. "You are my
sister
after all." While I said it, my soapy cock was in the cleft of her buttocks, and my hands were spreading sudsy foam all over her breasts and belly.
"Of course," she chuckled. She leaned her head back and kissed me. Then she revealed that Amy had asked her if it turned her on to watch while we had sex on Wednesday night. "I told her it was really hot to watch that, but of course, you're my little brother. It's not like we could have sex or anything. I did admit that sometimes when I sat in your lap I could feel you getting hard, and that it turned me on. Did you realize that she actually pushed your dick into my mouth last night?"
"I thought so, but I couldn't see it."
Hope shook her head and then turned around to face me. She was grinning. "I have to say, this is incredibly fun. But it's tough for me to act reluctant. Amy gets so turned on just thinking about getting the two of us to do something naughty."
