"Listen to that. Her bed frame keeps bouncing against the wall."
"If it bothers you, in the morning I'll pull the bed an extra inch away from that wall."
"No, don't bother," my wife chuckled softly,"I don't really mind the sound of our daughter masturbating. After all, she is eighteen now."
"She seems to do it an awful lot though."
"Does that bother you?" another chuckle, deeper, throatier. "Knowing that your little girl is a sexual creature?"
The sound of the bed bumping against the wall that separated our bedroom from our daughter picked up pace as I lay there, knowing that there was no safe response.
"You still think of her as that curly headed pixie in the ruffled skirt, who went through the awkward tomboy phase and skinned her knee falling when you taught her to ride her bike. But she's a woman now. If you haven't noticed, she has all the right curves. Much like I did at that age."
This time, the chuckle was a true laugh. In the moment of silence that followed, I thought I heard moaning from the next room.
"I'm sure she'll get louder when she climaxes," her mother read my mind. "I'm guessing she thought we were asleep already and wouldn't hear."
"Or maybe she wants us to listen," I meant to think the words, but they hung there out loud in our darkened room as our daughter's moaning intensified.
"Ohhh, I think someone is having some guilty pleasure. And I don't mean our daughter. Well, maybe her too."
My wife chuckled again, shifting her head onto my shoulder. Her fingers crept across my thigh and grasped my cock.
"I was right, given how hard and stiff your cock is."
My wife's hand snaked my erection clear of my jammies, and then her fist pumped my shaft slowly, just once, down to the root and then up again. A fingernail teased my gaping slit. The bed frame started bumping our wall faster, as our daughter's moans became groans.
"It's all right, I don't mind. In fact, I kind of like it," my wife whispered. Her free hand took my arm and led it to her groin. "Feel how wet I am."
My fingers stroked her slit, but then she just held my hand there, the thumb against her swollen throbbing clit.
"Are you imaging watching her? She probably has her sleep shirt rolled up her hips. Or maybe shoved all the way past those firm young tits so she can caress her own nipples while she fingers her clit."
My wife slid her hand down my shaft again, and this time she teased my balls with her little finger.
"I wonder if she's got three or four fingers inside her squishy wet cunt, wishing she had a fat cock to fuck her. Maybe she's wondering how her Daddy's cock might feel in her tight gash. I bet she lies awake to listen to us fuck and wishes that it was her that was in this bed getting stuffed with your throbbing man meat."
By which point my cock was indeed throbbing in my wife's fist. Her hips were gently humping up against my hand as she guided my fingers down her slit and I instinctively started to slide a digit into her opening.
"Do you wish that it was you making our daughter's bed bump up against the wall? Would you want me to be lying here, listening, touching myself? Or in that room, watching?"
I shifted, causing my wife's head to slide to the mattress, finding here nipple, sucking it through the flannel of her nightgown. I noticed that it was rock hard before my lips even found the nubbin.
My wife moaned in appreciation, much more gently than the groans from the next bedroom which were growing in intensity.
"You haven't seen her naked since she was a child," my wife spoke. "Her nipples are the exact same shade that mine were before we had kids - that lovely bubblegum pink that you loved so much. I bet you'd love to suck them just like this."
She giggled and wriggled. That in turn made her fist shift around my cock, which jiggled.
"I don't mind you closing your eyes and fantasizing about making love to your daughter. In fact, it makes me pretty wet."
My fingers slid deeper into her quim, confirming this fact.
"She trims her pussy hair just like I do, but lately she's been wanting to shave her snatch bad so she can wear little micro-bikinis," my wife snickered. "I'd love to see how your face and your cock react the first time you see her in one of those."
My cock pulsed in her fist as if to demonstrate how our lithe daughter in a teeny bikini would make it react.
"She asked me if I would shave her, but I've never shaved, so as much as the idea excites me, I might be too nervous. I know you'd love to watch, but it might be better if you did the shaving instead, since you shave every day."
My whole body stiffened as I imagined touching my girl all around her most intimate places. My wife ran her hand around and across my butt, teasing my asshole, but targeting my balls, which she spent a long moment kneading.
"Of course, doing that would make you hard, and likely she'd get wet too." Another girlish giggle. "I'd be watching, telling her I was the chaperone, but I'd get even wetter. I'd want to take your cock and shove it into her cunt. Well, I might need to lick it a bit first. Your lollipop, I mean, not her cunt. Though I might lick that too, I suppose."
I could feel my seed start to surge. No doubt she could as well, since she fashioned her fingers into a fleshy cock ring and wrapped it around my root to make sure I did not come too quickly.
