Jen put on the movie and we settled into the couch. I sat between the two of them, our usual sitting arrangement. Mom took a slice of pizza and sank in next to me. It was an action flick, one of the run-of-the-mill where an entire computer-generated city is laid to waste before the end. Jen settled onto her side, eventually closing her eyes. After a while Mom looked over at her. Jen was curled up on the couch, her butt close to me. Her shorts had ridden up, and it was clear she had nothing on underneath. We both could see her labia poking out from one side of her shorts.
“Well, there you go,” Mom sighed. “As usual.”
“I’ve already seen her naked, it’s no big deal.”
“I guess not,” she said, nodding. “You’ve been exposed to a lot over the last few days.”
“Not complaining,” I whispered.
“I bet not,” she smirked. She was still looking at Jen’s ass. “Jen’s got a nice ass.”
“So do you,” I said. I was getting hard, and Mom noticed.
“Who’s that for?” she said, eyeing my erection in my shorts.
I reached over and tugged at the neckline of her scrubs, pulling them down a little. I stared at her cleavage, and she grinned.
“You’re not suggesting that we fool around right now,” she purred. “While my sister’s asleep.”
I meant just that, and I slipped a hand into her shirt and cupped her tit to make my intention clear. She grinned.
“Just a blowjob,” she whispered. “I don’t want to wake her up.” Then she reached down and unzipped my shorts. She had my dick in her hand in seconds, stroking it. “God, if she woke up right now…”
Mom bent over and took me into her mouth. I made no sound, fearful of waking Jen. The idea of her sleeping right next to us heightened the experience. I don’t know how many dicks Mom had sucked, but she was very skilled. She used her hand at the same time, working me slowly but firmly. Her ass was sticking up, and I reached over and gently gripped it.
“You like my ass?” she whispered.
“Mm hmm,” I whispered, afraid to speak and wake Jen. Mom stopped, reaching back and pulling down her scrubs. Her ass was bare, and she darted a hand between her thighs and returned to my dick. I grabbed her ass hard, and she took me in deeper.
Her head bobbed up and down gently, careful not to wake her sister. Mom took her time, sucking me and rubbing herself. I ran my free hand through her hair. Every so often she paused, letting me slip out of her mouth as she looked up and me with longing eyes.
I was about to come, and I gently squeezed her ass. She took me in deeper and I came, spurting cum into her mouth. She swallowed my seed, drinking me down as I kept coming. My dick popped out of her mouth and I kept coming, spurting cum into her hair and on her cheek. She gasped, rubbing her clit furiously, coming with me.
She kept still, but I could see her body tense up and then release. She came, my dick still pulsing and spilling cum onto her cheek. When we were both finished she sat up, her hands slick with my cum and her wetness, and she grinned.
“I’m going to bed,” she said. “I needed that.”
