I was deeply asleep in the spare bed at my sister-in-law's home and didn't feel anything as Jess slipped into bed with me. It wasn't until I felt the warmth of her body against mine as she snuggled in behind me that I came half awake, and even as I felt a small hand slip into my boxers and wrap around my cock I was more dreaming than conscious.
My body responded. Of course it did. I was fully erect when I finally woke up and Jessica was letting my full length slide through her hand.
"What the fuck," I cried out as I rolled away from her and then stood beside the bed, looking down at her, my cock bouncing around in front of me.
She rolled onto her back and looked up at me with a nervous grin on her face. In the moonlight that filtered through the window I could see that the sheets were pushed down around her hips and her breasts looked luscious and perfectly shaped, with small erect nipples. I had seen Jess in a bikini many times over the years, and I had always quietly admired her body, but just seeing her topless for the first time caused a rush of blood to my cock that surprised me.
"What are you doing," I asked her as she sat up cross-legged on the bed, pulling the sheet into her lap and across her legs. I grabbed a pillow off the bed and held it in front of my cock, feeling slightly ridiculous, but not sure what else to do.
"I think you know what I was doing," she told me with a grin that didn't really hide the nervous look on her face.
"We can't," I told her. "What about Ben?"
"Ben's asleep."
I tapped the screen of my phone on the bedside table and saw that it was a bit after 2am.
"And he can sleep through anything." She told me. "He won't wake up."
"That's not what I meant. He's your boyfriend, you live together. You've been together for what, three years?"
She scooted over to the edge of the bed, still wrapping the sheet around her waist, but I was suddenly conscious that her head was right in front of my cock. I had softened a bit as we had talked, but I was suddenly hardening again as I admired her pretty mouth. I hugged the pillow a bit tighter to myself.
"I've lusted over you since the first time Samantha brought you home to meet mum and dad. I thought she was so lucky to have such an amazing boyfriend; so good looking, smart, funny. I even told her one night, after a few wines, that if she ever dumped you, I would grab you for myself."
"She actually told me that," I confessed with a smile. "One night in bed, we were joking around, playing a silly 'what if' game. You know, who would I want if she wasn't around. I didn't mention you, but Sam asked me if I fancied you, if I found you attractive. I lied and said no and she called me out for lying. She had seen me notice you, you know, aesthetically." I grinned. "She had laughed and told me I could look, but not touch. Then she told me that you had me in your sights if she wasn't around. That was just a month before she died."
"Fuck."
"Yeah. That's two years ago now."
"So you do find me attractive," she asked after a while, looking up at me. The look on her face suggested that she wasn't sure if she really wanted to hear the answer.
"Of course I do, you are a beautiful woman, as was Sam."
"Would it be too weird to have sex with your dead wife's little sister. Would it bring back too hurtful memories?"
"You look so much like her," I told her. Sitting down on the edge of the bed beside her, keeping the pillow on my lap. "It would probably bring back good memories."
"I guess I have had a bit of an obsession with you," Jess told me, putting her hand on my leg and digging her fingernails in gently. "I've thought about this, wondering if it would ever happen, especially since, you know, you're single again. Have you been with anyone since we lost Sam?"
"No-one. I look after myself when I need to." I looked down at Jess' hand as she now ran her fingernails along my inner thigh.
"I told a girlfriend about this obsession. She thought I should just fuck you, to get you out of my system."
"Is this what this is about?"
"I worry that if we do this, it will just make my obsession worse. Have you ever thought about me, you know, sexually, have you wondered what we would be like together?"
"Yes," I confessed
"Wow."
"Especially in the past couple of months, when I knew I was coming to Sydney for this week of work, that I would be staying with you and Ben."
"Did you masturbate thinking about me? Tell me how you wanted me," she asked as she turned towards me, pulled the pillow away from my lap and slid her hand up the leg of my boxers and back to my cock, wrapping her warm hand around me. I was half hard, but her hand had me hardening quickly.
"Every which way," I answered with a sigh as she tightened her hand slightly, "but especially your mouth. You have an amazingly sexy mouth."
She rolled off the bed and knelt in front of me.
"Can I please suck your cock?" she asked, with the most wicked smile. "Lift up" she told me as she pulled my boxers down over my arse and down my legs, before she threw them into the corner.
She didn't wait for an answer before she pushed my knees apart and lowered her head to my cock, licking around the tip a few times, before taking just the head in her mouth. I sighed contentedly.
I took a handful of her hair and tilted her head back, my cock slipped from her mouth.
"Are you sure?" I asked.
"Very. You can stop me if you want to, but I want this."
She lowered her head back to my cock, taking half the length into her mouth. She started humming. I looked down, watching her head bouncing up and down, taking more and more of my cock in her mouth. Sam had given amazing blowjobs, and it was as though her little sister had taken lessons from her.
As she used her mouth, she also kept stroking the base with her hand, sometimes firmly, sometimes lightly, bringing me close then backing off. When she licked the tip, or ran her tongue along my length, she looked up to make eye contact, then when she took me entirely in her mouth, I watched the back of her head bobbing sexily. Eventually she lifted her mouth away from me, shuffled back a bit, pushed my knees further apart, and took one ball then the other in her mouth, while gripping me firmly.
"I'm going to come," I grunted.
She left my balls and quickly took my shaft back in my mouth, just as I started to erupt. She pumped my cock with her hand while the warmth of her mouth surrounded me and her tongue teased my urethra. I thrust into her mouth, emptying myself across her tongue.
"Mmmm," she said eventually, lifting off me as she swallowed.
I lay back on the bed, sated. Jess took a drink of water from my glass on the bedside table and rinsed her mouth before she slid up onto the bed beside me.
"Now I need you to fuck me," she whispered in my ear.
