(This story is beefed up to make it more readable...but the story is true...and the dialog is basically how i remember it going down)

one of my first bdsm experiences was with a family friend who lived down the street.  I was 18 about to go to college...and was taking the summer off.  My Aunt's friend Trudy had injured her back and needed help around the house...my Aunt volunteered my help.  Trudy was about 43 a BBW with short sandy blonde hair and no children.  She had been friends with our family since i was a child.  i was happy to help out and was a little excited to be spending some time with Trudy.  All through my teenage years i would hear snippets of Trudy's exploits (parties, sexual encounters and the like).  They didn't really pay much attention to a horny teenager who would appear to be uninterested in hearing such stories....but was secretly listening intently.  It didn't help that Trudy would flirt with me every chance she got...and i had learned to flirt back with gusto as well.   It was a game we played together. Trudy was in bad shape...she could barely move and was in constant pain and on pain killers.  My Aunt had been helping her the first few days...and told me a little bit of what to expect.  The first day i went over...she was still in bed and hadn't eaten anything by 11:30am.....she was not in a good mood.  "Where the fuck have you been?!?" ....i was surprised because Trudy had always been so kind to me.  i told her i had gotten up and had some breakfast got cleaned up and came over.  She informed me that she could barely move and needed a lot more help...and didn't think i could do it.  She told me right off that i needed to be there at 9am each morning....so she could go to the bathroom and not have to use the bed pan.  She then leaned sideways and lifted the covers...... i got my first glimpse of Trudy's ass.....large and wonderful....but there was something in the way.....a metal hospital bed pan.  "I had to go to the bathroom in this.....because i couldn't get up without your help.  Help me get this off of me....i have been sitting like this for 2 hours."  i quickly reached over and rolled Trudy over more and removed the pan....it was kind of stuck to her so when i pulled with more force it released itself and jerked...spilling some of the contents on my pants, shoes, and socks.  Most of it went on the floor though.  Trudy heard the splashing and got very angry. "Be careful stupid....".  i was so conserned at what i did that i didn't even get a good look at her ass as i got the bed pan out.  It was too late now because she had rolled over and seeing what i had done she started yelling again.  "Clean that  up....dear God your like a fucking retard". i quickly ran off and got a dry towel and a wet towel. Luckily she had wood floors and not carpet.  As i got down on my hands and knees to clean up her pee....she said "serves you right for not getting here on time....now your going to smell like pee all day".  i said "yes Trudy" in a sarcastic way....trying to lighten the mood a little.  She quickly grabbed me by the hair and lifted my head...i cried out in pain and i will never forget what she said.  "Listen BOY....in MY house you will treat me with respect....do not use my first name unless i give you permission....you respond with Ma'am or yes Miss Trudy....and i don't want to hear your bullshit sarcasm....do you understand me?" and she shook my head.  i had never been treated by her this way and it scared me a little....i said "yes Ma'am" quickly....and she let go of my hair.  i quickly cleaned up the pee and went and emptied the bed pan in the toilet.  i returned to find her uncovered and looking kind of helpless.  i don't think she ever liked to be helpless....and this is why she was so angry during this time.  She told me she needed to take a shit.....very matter of factly...and that i needed to help her to the bathroom.  i slowly helped her get upright and walked her to the bathroom.....opened the door and got her inside......i turned to leave.  "Uh i need more help than that......i can't bend over well....Listen if your going to be so shy i'm going to hire a nurse and you can go home and play with yourself or whatever you do."  Because of the smallish bathroom i had to kneel down and put my hand under her gown....find her panties and lower them down for her.  As i got them around her ankles....i noticed the crotch of them were wet.....i figured it was just pee.  As i got them lowered...she put one hand on my head....and lifted her gown...my face was eye level with her hairy pussy....i almost gasped.  She slowly and gingerly lowered herself on the toilet.  She farted loudly and began to poop right in front of me....i was beet red.  i got up to leave...but she said.." i need fresh panties...there in the top drawer".  So i got up...closed the bathroom door behind me and went to her dresser and started looking for the panties.  She said she wanted the black ones....silky ones.  i opened the drawer and did not see any black ones...i began moving the panties around....and started getting aroused....they were all so silky and smelled nice....as my hand began moving around it hit something large and hard....i moved the panties aside and saw a huge latex cock shaped dildo.....wow...it was huge....i quickly covered it back up and found a pink pair...silky...and brought them back. i told her i couldn't find the black ones....and slightly opened the door and tried to hand her the pink ones...she said " i want the black ones. Plus i can't reach them stupid...come in."  i came in and could smell a mixture of her feminine scent, pee, and poo. " Go downstairs and see if there hanging dry in the laundry area....my panties are hand washed...in the sink next to the dryer....i usually hang them up there".  i turned to leave....and she said.."hey...take these with you....put them in the sink and rinse them out"  She kicked her leg up and the panties flew into my hands...and i felt a little dampness to them.  i went downstairs and found the black panties....they were hanging up as she said.  i turned to the sink and was about to put her dirty ones in it...when i caught of whiff of them...they reaked of pussy....i was almost in a trance by it and quickly found myself smelling them....(i was a typical horny boy)....There i was holding a pair of dirty smelly panties in one hand up to my noise....half wet with pee....and rubbing myself through my shorts.  A loud thumping noise was heard from upstairs and it got me out of my horny head space....i stuffed the dirty panties in my pocket and ran up the stairs with the fresh ones.  i knocked and asked if she was all right....she said come in.  i came in.  She was on the toilet trying to lean forward and wipe her ass at the same time.....she said she was having trouble and needed help....i hesitated...and she yelled "well it's not that fun for me either".....i knelt down and to to the side of the toilet as best i could....my crotch bumped her leg...and i suddenly hoped she couldn't feel my hard on from the panties.  She handed me some paper and i wiped her ass as quickly as i could and leaned back out of the way.  She said..."nope....still dirty....try again"....i tried 3 more times to get her clean to her satisfaction......the last time i wetted the tissue and really wiped good....i could feel the ripple of her star shaped pucker through the tissue as i wiped....and i found myself getting excited.  She flushed and i put her panties on and helped her pull them up....getting face level with her crotch again.....i turned away after a second or two....but she said "Listen i don't need you sneaking peeks at me this entire time.....i don't like being so helpless and i don't need a little pervert like you trying to catch glimpses of my pussy.  When you are helping me and i am exposed in anyway....i want you looking down at my feet....in fact unless i tell you otherwise i want you looking down at the floor.....i don't like you seeing me in this way....and this is MY house...MY rules.  Is that understood."  i did not answer quickly enough and she grabbed my hair kind of hard...."is it??"  "yes Ma'am" i replied...what else could i do....i didn't want her reporting back to my mom that i was a pervert taking advantage of a helpless women...a family friend to boot.  "after you get me back to the bed....wash up....and go make me breakfast"  the old harsher tone was back.  I did just that....helped her back to bed...watching the floor as i went....and went and made breakfast for her.  i must say that it was kind of exciting....to have seen her pussy.  i thought about it while i made her breakfast and remember her panties....i took them out and began to smell them ....they smelled amazing.....i don't know how that breakfast got cooked...because i was sitting there in her kitchen...smelling her dirty panties and stroking myself through my shorts. i put away the panties ...finished up (didn't have time to cum....thought i would take the panties home and really go at it later)...brought Trudy her breakfast....i did my best to not look at her...but did catch a few glimpses of her eating....and saying it was good.  She had me bring her some books and magazines...the paper...kleenex....pens and paper...all kinds of stuff...i removed her tray when she was done eating and was told to come back in 2 hours to help her use the bathroom again. I left the bedpan just in case.  i went home and took out her panties....locked myself  my room....and practically wore them on my face as i laid on my bed and jerked my cock furiously....at one point i stuffed the crotch in my mouth and tasted a very sweet dried substance that quickly came alive with my wet saliva.....i pumped my cock more and more...faster and faster thinking about Trudy's hairy pussy....and how if she wanted to she could have pushed my face right into it while i was in the bathroom.  With that thought i exploded all over my chest with rope after rope of thick cum.  i was exhaused...and dozed off with the panties still in my mouth.  <continued later>
