Tara began to speak. "Stay with me on this. Put your panty's back on." "Aww, but we we're having so much fun." Jenny cooed. "Just wait and see. What I'm going to ask you to do." Tara says as she takes a deep breath. "Is to go to the bathroom in your panties". Tara looks confused "I've already told you silly, i'm all out of pee!". "I'm not talking about pee. I want you to poop your pants". Tara said frankly.
"What?! I can't do that! That's disgusting! Look, enough is enough" Jenny protested. But she already knew it was too late. Tara had given the order, and Jenny must comply no matter what. She could feel the pressure build up in her bowels. Her face took on bright red color as she fought her body's reflex to push. "No I don't want this! Please! Why... Why does it feel so good though?"
Tara moved over behind Jenny's ass and knelt down. "I'm sorry to have to do it like this, but once you try it i'm positive you'll love it. Just trust me. Let it out!" Jenny's hand shot down the front of her underwear unable to resist the urge to pleasure herself. She followed Tara's command and let go of her control as she felt her underwear fill up with her firm, hard, brown shit. She felt the material move and bend as it made way for her growing load. Tara, one hand down her panties, used her free hand to grab the growing lump and squish it around her panties. She put her face to Jenny's ass and began to inhale. The fumes making her orgasm uncontrollably.
Jenny too screamed out in what seemed like her 100th orgasm of the night. "Oh god you were right! This feels amazing! I've still got more, so much more! Jenny bent her knee's and pushed. The lump in her panties was growing at an unprecedented rate, the fabric weakening under it's texture. "Quickly on the the bed! Sit on my face!" Tara yelled. Jen was happy to oblige she leaped onto Tara's face and continued emptying her bowels. The bulge was now so big the underwear gave way under the strain and the poop was sent flying all over Tara's face and breasts. Out of shit and coming over another successive orgasm Jenny moved from her lovers face and inspected the mess. "Tara? Are you alright?" She asked cautiously. "That. Was. The best possible outcome. I love you so much right now." Tara's smile was clearly visible as she wiped off the fecal matter covering her.
Jenny just stood there before yelling "I want you to shit on me too!" Realizing what she said she became incredibly embarrassed. "I mean... It's only fair. My panties broke on you..." Tara wasted no time and threw Jenny onto the bed, placing her ass millimeters from Jenny's face. "Do it. Please" Jenny whimpered. Tara began to push, gas escaping from her sphincter, Jen found herself relishing the smell. Then she could see a brown tip push it's way out from the bottom of her white panties. Tara began to push harder and the lump continued to grow. Jenny licked at it as it grew in size,savoring the pungent flavor. Eventually it hung so that she was able to take it in her mouth she chomped and chewed on the lump. Tara stopped pushing and began to rub her ass up and down Jenny face before both girls concluded in glorious orgasm.
The two concluded that their toilet games had reached its climax for the night and decided to clean up. In the end throwing out most of the sheets on Tara's bed. The two decided to curl up on Tara's couch for the night and watch a movie together, confident that Tara's parents wouldn't return for another few days. The two fell asleep and awoke early the next morning, where a newly rested Jenny suddenly had an idea...
