Helping with step-daughter's health

My wife's 18yr old daughter Samantha, who we call Mandy, has been having a lot of issues with stomach cramps and going to the washroom recently. My wife, Katie, took her to the doctor and she was diagnosed with Anal Stenosis. There were several medical options presented but the doctor also suggested that if she was sexually active she could try regular anal sex to help with the problem. Mandy is a good girl, no boyfriend and whoring around, and she is heavily focused on her university studies. On the way home Mandy asked to stop by a sex shop to buy some toys that could help her out. While browsing, Katie jokingly pointed to a dildo and said "that looks just like your dad's" to which Mandy jokingly replied "maybe I should get him to help me out." For some reason this intrigued my wife and she seriously suggested they leave the store and she would talk to me about it. Wanting Mandy to feel better, i accepted the responsibility. Later that evening, Katie led Mandy into our bedroom for her first treatment session and left the room after saying, "Be gentle with her" Katie said, "she has not been able to go to the bathroom today and she has a tummy ache." Treating it like a doctors visit and nothing sexual, Mandy walked over to the bed, pulled her pj's down to her knees, and bent over on the bed. I grabbed some lube, squirted it on my pinky, and gently began rubbing around Mandy's butthole. She quivered briefly and laughed said "well that's a first." I placed my pinky at her entrance and told her to squeeze like she was trying to poop and when she contracted, it would pull my pinky in. Doing just that, her tight starfish pulled the entire length of my pinky in. "Awww fuuuck" she whimpered before quickly apologizing. After easing my pinky in and out i moved up a finger size every few minutes. After giving her backside a thumbs up for a few minutes, i pulled my pants and boxers off slowly and brought my raging boner to her forbidden entrance. "ok Mandy, this next size up will be a bit bigger." "I'm ready" she said. I pushed my cock to the entrance of her butthole, pushed past the resistance, and plunged in balls deep. "Yeeeoooowww" she screamed. I stood still to allow her sphincter to relax around my wood. "ok you can move now dad, but slowly." I slowly began fucking her ass and increasing the pace every few minutes. After 15 minutes, I was banging Mandy's ass like a rabid ape. "Oww daddy i feel weird I don't....." whoosh a solid clear stream followed by several spurts shot out of her vagina and right into the pants still around my ankles. "What the fuck was that!" she exasperated. "That was an orgasm sweety." "Wow what have i been missing out on dad!?" I kept pounding for a few more minutes when she suddenly cried out "daddy I think I need to poop." "No Mandy" I said, "It just feels that way when something is in your butt." "Really daddy I need......" i yanked my cock out and in hot pursuit a foot long turd shot out of Mandy's ass and landed two feet behind me. Seeing her gaping anus after completing its natural duty, I plunged the full length of my cock back into her ass and shot a solid stream of cum deep inside her. "Owww fuck daddy that's warm" she whimpered. "Thanks daddy my tummy feels a lot better, I normally need to poo at least twice per day so ill be back tomorrow morning." With that she stood back up, pulled up her pants, grabbed the brown rod she left behind, and walked out of the room. A few seconds later Katie walked into the room with an entirely soaked crotch. She had apparently been watching from the hall and had been satisfied with what she saw. "How was her treatment today hubby" she said. I responded "she is making excellent progress and has a follow up appointment tomorrow morning."
