Mom and I slept together that night. We spooned and mom spread her cheeks for me to place my cock between her cheeks rather than have it against her back. I made sure to place the head of my cock against her dark rose as her cheeks pressed against both sides.
My left arm was under Mom's pillow and my hand cupped her breast as we lay there.
"Baby?"
I whispered in her ear, "yes Mom?"
"Baby, I need to confess that I am a nymphomaniac. I am addicted to sex. That is why I have so many toys. I never bothered trying to find your father because you were conceived after a night where I, along with some other cheerleaders, had fucked the entire varsity football team, including the coaches. I had cum from at least 7 guys in my pussy that night. I am sorry you grew up without a dad."
My cock was not up for more sex just yet and needed a little time to recover. Mom suspected as much and continued. "Let's lube your cock and my ass and ass cheeks baby so, when you get hard, you can just slip it into my ass and get some relief. A nympho mother absolutely doesn't want or need her son to waste a hard on."
Mom pulled out some silicon based lube from her night stand and smiled up at me as she liberally coated my cock with it. She then cleaned her hands with a kitchen towel she had next to the bed before saying, "Baby."
She twisted a clear plastic tube with a plunger onto the lube container and filled it with lube, making sure to get a little on the sides of the tube. "Slip this deep into your loving mother's ass and holding the plunger still, slowly pull out the tube so the lube spreads evenly inside me?"
Mom handed me the plunger and leaned over the side of the bed, spreading her cheeks. My breath caught at the beautiful sight of my mother's winking sphincter and inviting pussy. I gently inserted the tube as deep as I could into her ass and pressed the plunger as I pulled out the tube, leaving a small dollop on the outside which I made sure to spread around just a bit.
"MMMM, that's perfect baby. Now take some lube and make sure the insides of mommies cheeks are well lubed so you can slip your cock between them with ease."
We spooned again and my cock slid easily between her cheeks with the head nestled against her now wet rose. Mom took a deep breath and relaxed her sphincter and the tip of my cock actually nudged inside even though I wasn't hard.
We fell asleep, connected in that naughty and very sensual way. Sometime during the night I awoke with a raging hard on sunk deep into mom's very slick ass. So, like any boy who can fuck his mom anytime he wants, I slowly began to fuck her hot, slick, willing ass.
Mom was still asleep but I could tell I triggered a wet dream as she moaned and spoke some garbled encouragement. I kept up a slow, steady pace, sliding out to the ridge of my cock against the inner ring of her anus while slowly gliding in as deep as I could go.
I was balls deep in mom's ass when she woke up. "Baby! Are you being a naughty son and ass fucking your mom while she is asleep?"
