This was the moment I couldn't be more into and the reason I can't stop thinking about. She used both hands and quickly slid her shorts and panties down over her knees and her legs spread. I was still laying on my side, with my fingers exploring her clit. I could feel the heat and wetness coming from below. As I spread her and inserted a finger, she moaned. It was subtle and quiet, but I could hear it, and it started making my dick hard.
I moved by hand back onto her firm breasts as those have been a source of lust for me. I could feel her hips moving, craving my attention back to between her thighs. I obliged, moving my hand back down and teasing pressure on the outside. This time I wanted to hear that moan again, I inserted two fingers. The moan was vocal and deep, I continued to play and reach deep into her wetness making each breath count. I was now fixated on that moan and wanted it to continue.
My dick continued to demand attention, I slid my pants off and pressed my dick against her thigh. No change in her breathing or hip movement, just continued to enjoy my fingers deep into her pleasure. I grabbed her hips and positioned her in a way I could pleasure her and tease with my hard cock against her vagina and clit. I didn't want to insert my dick into her, just wanted to continue to tease each other. My dick was now rubbing her clit and gliding along her wetness. I continued to power my hips into her. Stroking her clit with my head and shaft now. Her face was lit by the screen saver on the TV and I could see her throw her head back while moaning. She would have let me fuck her if I wanted to. And the thought was hard to resist but I wanted to give her something I knew no one else her would have been able to do her age. Focus on her pleasure and not mine. I moved her hand onto her clit and joined her in massaging both my firm dick and her full pussy. I helped her apply pressure on my shaft that was teasing her clit. Her movements started stuttering and I knew she was going to come. I was fully ready myself. I pushed her hand onto my cock so she could feel it pulse through her fingers. My fingers went inside to stroke her g-spot to fill her orgasm. She moaned so loud I had to whisper a small 'shh' in her ear.
I stopped all play after that and a few moments later, I climbed out of the couch, said "Goodnight", and went to mine. I could hear her slowly move out of house and she left on her own. It's been a week or so since the incident but I can't stop thinking about it.
Does she think about it? I replay her moaning over and over and it makes me hard now just thinking about it. I know this was a one-time adventure and I will treasure it for years.
