Respecting One's Elders (piss)

I wake up to the feel of Grandpa's thick cock slowly pushing it's way into my wet asshole. "Mornin' Hailey", I hear him grunt softly over my shoulder when he notices I've woken up. It's the first full day of our weeklong summer trip to Mom's parents' house. The whole family had been up super late as we all caught up. Grandma and Grandpa had been very keen on fucking everyone more than once immediately, trying to cram in the maximum amount of quality time like elder relatives always do. Their stamina hasn't waned a bit in their old age - Grandma was even teasing my brother Aiden when he wanted to go to bed at midnight instead of letting her tit-fuck him. I sleepily flip though the memories of yesterday's high points as I arch my back and push against the leathery cock slowly sinking into my bowel. A leisurely ass-fucking ensues, throughout which I teeter on the edge of sleep despite the pleasing sensations.

His orgasm shakes me awake again. After I feel his modest load stop pumping into me, Grandpa stops moving and asks "Have you been a good girl and helping your Dad with the toilet in the mornings?" I have, and I say so. Since I turned eighteen, I've been in my parent's bed most nights, and Dad in mine quite a few of the rest. He still uses Mom in the mornings too, but she started insisting that after eighteen years of raising me, she deserved to sleep in a little more often when I was only a roll-over away. Grandpa does a breathing exercise and I feel his cock soften slightly, then my colon is suddenly filling with his warm piss. My hand starts rubbing my clit in response without my semiconscious brain even thinking about it. He empties his bladder in a trickle, giving me time to wake up and get worked up. By the time he signals he's empty, I'm actually quite close. He stays planted in me to maximum depth as I go though a quick but firm orgasm, anus clamping hard enough on his cock to make him suck in air through his teeth and squeeze my ass hard with one hand.

I don't even realize I'm asleep again when Grandpa shakes me gently and says "Sweetie, I can't stay in you all morning. If I go soft we'll have a mess to clean up." Reluctantly I clamp my ass and push his cock out. Standing up I twirl and wave my hands over my teen body, "This can't keep an old man hard?!" I mock at him. "Some times nothing keeps an old man hard, baby girl". He says gruffly, propping himself up to do the crossword on a paper from his nightstand, limp cock and balls lying flagrantly over one thigh. I walk around the bed and try the door to the master bathroom, but it's locked. "Your grandmother is in there, honey." I hear from behind me. Sigh. I squeeze my anus harder to contain his piss and head out into the hallway to use the guest bathroom. Halfway there, my mother steps out of my parents' room with the same careful ass-clenching steps I'm using. I hear my father flop over on their squeaky bed behind her.

With a knowing smile she follows me into the guest bathroom. Like all bathrooms there's only one toilet, so I move aside and motion for Mom to take it first. She sits down gratefully. "How'd you sleep, honey? Dad used to keep me up all night when I was your age." "Great, actually." I reply as my mother lets go of her own burden of my father's urine she's carried here in her bowels. Her legs are spread wide, as is polite when others are in the bathroom, and I watch the bright yellow stream fall into the bowl as we have some basic morning chitchat. It's easy to spot the huge white load of Dad's jizz mixed in as it goes by. While we talk, Mom is staring at my abs thoughtfully, lustfully. As the flow from her rear peters off and she begins to release her own piss she says "Actually, why don't you go in that for me?" and gestures behind me. Turning, I see a plastic cup on the counter.

I'm all to happy to relieve the pressure in my colon and happily squat down over the convenient vessel, directly in front of Mom. She watches closely as Grandpa's fluids fill the cup and makes a small noise of warning slightly too late as the last few ounces of my contents are too much and overfill the container, forming a yellow puddle between my feet. "I'll take that," Mom says eagerly, jabbing her hands out. Carefully, carefully, I lift the completely full cup of piss to her waiting grasp, noting Grandpa's cum floating on the surface. My mother greedily slurps the semen off like cream, then goes back for a full drink. She looks lost in thought as she savors the taste. "Tastes just like I remember. It brings back so many memories. .." she sighs. I express some disbelief, at which she jokes "your grandmother has probably been feeding him the same meals for the last 20 years."

Having reduced the volume of the cup to a mobile level, Mom realizes she's kept me waiting all this time, exclaiming "Oh honey, you need to pee too, I'm sorry!" as she leaps off the toilet, forgetting to wipe in her haste. With **** gratitude I whip around and let go of my own urine like a dam failing. As I go, my bored eyes bounce around til they land on Mom, standing just off to the side of me and nursing the cup of her father oblivious to the world. I notice the wet trail a couple of drops of her unwiped piss are leaving down the inside of her thigh and lean forward to lick them up for her. At the touch of my tongue to her skin, Mom breaks out of her trance and steps closer to me when she realizes the small favor I'm doing. As I clean my way up to her vulva she remarks softly, "I'm so proud of you; you really know how to treat your elders well."
