Why?

VI

I looked up from my journal as I heard Lindsey enter the room. "She's down for a while, are you busy?"
"Oh good, and no, just let me finish this page." I scribbled a few more lines, then slipped the book back into its drawer. Lindsey had turned to stare out of the window and I walked around to face him. "The weather is good." He noted, gesturing outside, waggling the baby monitor in his hand.
"OK I'll sit in the sun with you, just bring it with us," I pointed at the monitor and led him out into the garden. He persuaded me into sitting on the grass by promising to scrub any potential stains out of the red sundress I was wearing, and let me lie my head on his chest as we basked in the sun. My hand rested on his hip and I began to thumb it, rolling my head into the crook of his neck. "When are you going to the studio?"
"Monday probably, I wanted some uninterrupted time here first."
"Hmm."
"I'd ask if you have any material but..."
"Hannah isn't even one year old yet anyway. I couldn't commit to something like that."
"I wish I didn't have to." I kissed along his cheek.
"I'm here, it's OK."
He sighed, turning himself to kiss me on the lips, deepening it out of frustration. Inching off to gaze at me a moment. I lay flat on the grass and he hovered above me as we explored each others' mouths. I gradually wrapped my legs around his, moaning a little as we ground against each other, arousal building. "Where's Karen?" He asked breathlessly.
"You're seriously asking me that now?" I grinned. He squeezed my ass in response.
"Ok, ok, she went to get groceries."
"Mmm good." He kissed down my dress, lifting it up as he reached my hips, and rubbing through my panties. I stood up and he followed me back inside where we fell back onto the couch. He pulled down my dress and felt my hardening nipples through the cups of my bra, as I ripped off his shirt and tightened my legs around him.
"Lindsey, please." I begged, pulling at his zipper. He unzipped and removed his cock from them. "You weren't wearing boxers?" I said out of shock, it being obvious that he was naked underneath his trousers.
"Why does it matter?" He said with a cunning spark in his eye as I pulled him down to kiss me again, his hands giving me attention between my legs.
"Karen will be back soon, do you want an audience?"
"Maybe."
"You're a fvcking dirty old man!"
"You love it."
"Give me a reason to."
He threw me down onto the cushion, yanked my panties to the side, and entered me fully as I dug my nails into his back. He moved fast at first and I moaned into his ear, then pushed his face down into my cleavage where he began to suck and bite my breasts, generating more than enough pleasure to top the pain. "Stevie, you're killing me." He groaned, straightening up as he adjusted me on his lap, his arms caressing my waist as my breasts bounced against his chest. I responded with a kiss, running my hands through his curls as our movements below more and more frenzied. I shed tears as he held me and we came over the edge together, whispering sweet nothings as we lay back on the couch, catching our breath. I heard the sound of the front door opening and quickly pulled my dress back up, Lindsey frantically closing his zipper. Casually placing his arm around me, we arranged ourselves in an innocent enough position, our smiles faltering as we recognised the woman who stood beside Karen.
