When I was about 16 (my sister was a little younger than I was but we were in the same grade) my sister started running cross-country in track.  She would come home with some horrible cramps in her legs.  She tried taking warm baths to alleviate them which didn't work.  She tried ice which didn't help either.  We lived in a small town that didn't have much in the way of amenities so our options were pretty limited.  After discussing this with my folks and sister I volunteered that Joe down at our local boxing club did rubdowns on some of the guys that trained there. 

As you might guess my folks' original reaction was "NO".  But we talked some more and then I played my trump card.  I volunteered to sit in on the massages.  I assured them there would certainly be no funny business if I was there.  They bought it.  I knew I was on the right track when my sister and I were heading back to our bedrooms for the night and she gave me a big hug.  She assured me that this was the best idea that I'd ever had in my life.  I knew that one reason that this was such a good idea was that Joe as a very good looking guy in his mid 30's who just happened to be black.  I knew for sure that the idea of Joe touching her while I watched was making her wet even now.

That next morning I stopped in at Joes on the way to school and told him about our request, me being there while he massaged her, too.  I think Joe recognized a fellow pervert because he never hesitated at all.  "Bring her here tonight about 8:00, that's about closing time and she doesn't need a bunch of guys watching." he directed.  I knew before we were done that somehow Beth would manuever things so someone would get to see her naked.  It was hell all day at school thinking about what and how we were going to do this.

Finally, it's 8:00 and we're at the club.  We just walked in and the last two guys were walking out.  I could tell that Beth was extremely excited about what was coming up.  When we walked in to Joes office he told Beth to go into the rub down room and get undressed and lay on the table face-down. As she was walking out he handed me a towel and told me to fold it in half and place it over her butt.  Somehow Joe using the words "her butt" got me stirred up too. 

I went into the room and she was already out of her clothes and laying on the table, naked.  I folded the towel in half and placed it over her ass.  It wouldn't cover it entirely so I moved it up so her pussy was exposed just a tiny bit.  I could see that she was lubricating.  As I fussed with the towel I let my finger slide the lenght of her slit.  She was incredibly, drippingly, wet.  I knew I would be able to help her get off and probably multiple times.

Joe came in the room with a bottle of massage oil.  I sat down on the chair and watched.  He started with her shoulders and neck, working slowly down her back.  I could tell that Beth was getting really impatient and really aroused.  I could see between her legs from where I put my chair and she was making a white cream that was oozing very slowly out of her cunt.  Joe then moved down and started on her feet.  Very slowly he worked his way up her legs.  I was very sure that he could smell her sex.  As he moved up her legs and started on her thighs she voluntarily moved her legs apart.  Rather too widely.  I knew she could feel the air on her pussy so she knew that Joe was probabl able to see her dripping wetness. 

Joe said "Beth, I need to work on your glutes if you want me to do this right and I also will need to work very high up on your thighs while I stretch your legs a little.  If any of this makes you uncomfortable I need you to tell me." 

I piped up and told Joe that Beth and I had talked about this on the way over and we were sure that to do this right you'd need to work very, very closely to her privates and we figured a way to handle it so Beth was comfortable and it would also let him do his work.  "Really?" was all he said.  "Yep" I replied and I stood up and walked over by Beth.  I told Joe that I was going to cover things with my hand so he could work as high as he wanted.  Old Joes eyes kind of lit up but all he said was "Let's get to it then."

I reached down and moved the towel so it just laid on one of Beth's ass cheeks.  You could see everything and she and I and Joe knew it.  I reached my hand down and cupped her pussy.  God it was wet.  She very very slightly moved her ass up just a tiny bit.  Joe started in her thighs.  Then he moved up to her ass cheeks.  I very purposefully moved my hand to the side quite aways so he could work her whole ass.  I let my hand go sideways into her extraordinarily wet slit and held it  there.  Joe could see her tiny brown hole and half of her pussy.  He started working closer and closer to her asshole and pussy lips.  When Joe would pull her ass away I'd pull on her pusssy the other way.  You could hear her pussy squish from her copious amounts of lube.  Joe worked a little closer and a little closer until he was directly touching her exposed little brown hole and the pussy lips that were exposed. 

"Well," he said, "we'd better switch sides."  Walking aroung to the other side, I took the towel with me.  Beth was totally naked on the table and horny as fucking hell.  Deciding to make things even more interesting when I placed my hand protectively on her pussy I slid two fingers inside of her.  Neither Joe nor Beth said a word.  We were all three breathing pretty heavily though.  When Joe would pull her ass cheek open I'd pull on her pussy so Joe could easily see me finger fucking my sister. 

I told him "Joe, I've got to run to the can, can I leave you guys here for a minute, would you be ok?" 

He assured my that everything would be fine.  I knew that Beth was wanting Joe do eat her or fuck her or something so she could come.  And I could tell it probably wouldn't take long.  I walked into the can and pulled out my rock hard cock and jacked it off.  Just a few strokes sent my come flying.  I tucked it back into my pants and walked super quietly back to the rubdown room.  Yep, Joe was eating her like there was no tomorrow.  Beth had her ass up in the air and I could see Joe alternating from sucking her clit to tongue fucking her.  The noise from her wetness was very arousing.  She came very quickly and super hard.  She made some grunting noises and pushed her pussy hard onto his face and then dropped back down onto the table. 

I made a little noise like I'd just entered the room and Joe stood up.  His face was covered with Beth's juice and come.  "I think we're ok for tonight" he said and told Beth she'd need to come back in a day or so for a followup visit and then he left the room.  We could hear him in the can jacking off.  Beth stood up and put on her longish tee shirt and said "Let's go."   I never questioned, I just gathered up her running shorts and rolled them up.  I knew that she'd be extra horny again when we got home and would need fucked. 

When we got home we saw a car in the driveway.  It belonged to one of Beth's teachers.  I asked her what was up, did she have a problem in this guys class?   She claimed not, but I wondered.  Beth demanded her shorts back but I wouldn't give them to her.  I knew she thrived on dangerous situations.  Into the house we walked.  As Beth walked up the stairs I looked up and could easily see her cunt.  It was still wet.  We walked into the living room and Mr. Robertson was sitting there talking to our folks.  They made the usual noises about being glad we were home, etc.  As luck would have it, the only seat available was directly across from Mr. Robertson.  He got so tonge tied from being able to see Beths pussy that he could hardly talk.  Seems that Beth was doing so well that he wanted to put her in an advanced class but needed our parents permisssion.  Which he already had.  Beth announced that she had to shower because it was late and tomorrow was a school day.  I knew there'd be more. 

Sure enough, out of the shower she came wearing her refitted baby doll nighty.  The top came just barely the tops of her panties.  It was very close to totally sheer,  you could easily see her nipples through the fabric and they were definitely erect.  Beth had cut the liner out of her panties and had then rubbed them with sandpaper.  They were also nearly transparent.  you could see her slit and the sparse jet black hair that not only didn't cover her slit, it drew your eyes to it.  Added on top of this was the fact that you could clearly see that Beth had lubed her panties from her juice.  Which made that spot totally transparent.  She made quite the show of gving the folks their goodnight kissses and hugs, all the while her pussy and ass are right in his face as she's bent over.

It was quite entertaining to see him leave and try to hide his boner.  I went to bed a little later and found Beth in my bed, totally naked, waiting for me to fuck her.  Which I did.  She came on my cock twice and I was so turned on myself that I couldn't pull out in time and filled her wet pussy with my come.  She stayed there until morning which got a little dicey when my dad found her bed empty.  But more on that later.....
