I lifted up my arm and re-positioned myself so he could lean on my chest, and he did, and we moved the blanket over us to snuggle.
"There you go, baby. Now if you fall asleep you won't hurt your neck."
He nestled into my chest and after a few minutes I felt his breathing slow, and knew he'd dozed off. I looked down at him, admiring my son's sweet, sleeping face. He looked so soft like this, despite the features of his face clearly shifting into that of a young man's over the last few years. I brushed his hair out of his face out of habit, and at the motion he turned towards me, away from the movie, rolling over on the couch and burying his face in the soft cotton covering my bosom. I held him there, and all my maternal instincts softened even more deeply. I remembered years ago holding him exactly like this, his mouth suckling at my breast. I smiled to myself, remembering, and then was surprised when I felt something different wash through me. I'd forgotten until just then how often I got aroused during breastfeeding, and that he had frequently sucked so hard many times early on in his life. Back then I'd felt ashamed, worried even that I was weird for enjoying it. I was surprised I'd forgotten about it until just now, but I must have simply put it out of my mind.
Now, with him lying there and remembering the way his soft, little mouth had brought me to orgasms all those years ago, I looked at his mouth and caught myself wondering what it would feel like to have it on my breast again. I knew it was wrong, but I was aroused to the point that I didn't care. I bet if I just lifted my shirt and pulled my tit out, he would latch on like muscle memory, still asleep. My shirt was already halfway up my belly from when he rolled over, and I wasn't wearing a bra. Careful not to wake him, I pulled up my top and revealed my left breast only, dropping it slowly and carefully onto his face. The warmth of his skin and breath against me sent chills all the way down my body and between my legs. This was it. I was going to feel my son's lips on my breast again.
I went to reposition my breast when, without my doing anything, sure enough my son moved in his sleep and latched on. I wasn't prepared for how hard he sucked right away and I caught my breath, letting out a small yelp. It felt good... really good. He was sucking and slurping at my breast, eagerly trying to drink my milk, and I loved it. I let him do that for a few minutes, watching and feeling a strange combination of motherly love and deep arousal. The arousal was only intensified by the shame and thrill I felt knowing how taboo it was that my son was sucking on his mommy's titty again after all these years.
Just then, I heard the familiar creaking on the stairs and realized my husband was coming down the stairs to the den. Shit! I thought he'd gone to sleep. I grabbed the blanket and pulled it up over my breast, covering our son's face, hoping my husband wouldn't think it too strange that our son was napping on my lap.
He came around behind the couch and saw us there, bending over the back of the couch to give me a kiss.
"Whatcha doin?" He asked with a peck.
"Oh, we were just watching a movie. James fell asleep so I covered his face so the light and sound wouldn't wake him." I hoped he took the bait.
