This happened when i was 18.  i was on holiday with my mate's family in Turkey.  It was myself (my name is Jake by the way), my mate Mark, his sister Vicky, his brother and their mum.  The weather was great and already me and Mark had met some really stunning girls so it looked like it was going to be a really good week.  On the third night we were all down in the bar drinking we were all inclusive so the drinks were free.  At about 1 in the morning everyone but myself and Vicky were feeling really tired and went to bed but i decided to go with Vicky to the Club in the hotel. After another hour of drinking we decided to leave and go to bed as the music was pretty shit.  When we reached our rooms which were across from each other i pulled out the key for my room that i shared with Mark when she went to give me a hug, which she always did so it was no surprise to me, until she planted a full on kiss.  Now Vicky is four years older than myself, around 5'8", pretty good looking and an o.k body but the most beautifully rounded pair of tits you are ever likely to see as i have frequently seen her in swimwear.  Unaware of where it might lead i replied with my lips and tongue and we stood there snogging for about 5 minutes.  She then whispered in my ear that we should take it further. However both our rooms were shared rooms.  But she just grabbed my arm and lead me to the stairs. we went down thwe stairs past the reception and into where the pool area was she closed the double doors and locked it.  She then turned to me and started to remove her black dress. I then started to remove my jeans and shirt so she was down to her lace bra and panties and me my boxers.  Her tits were just dying to be released so as she moved in closer to me she unclasped her bra letting her tits spring out and she stepped into the still running jacuzzi.  She beckoned me over and as i stepped in she started to remove her already soked panties.  She took one look at my crotch and saw my dick bursting to be released so she ripped my boxers down and my fully erect 8 inch dick sprung out.  She then stood up allowing me to grasp her enormous breast and kiss and lick her erect nipple.  As we kissed i felt her hand grasp my dick and continue to stroke in a smooth slow motion i then started to caress her soaking wet pussy and her head then lowered its way to my cock.  as her lips engulffed the head she continud to stroke hte base and caress my balls.  Within two mkinutes of this licking and caressing i couldnt belive that my ball were starting to tighten she was so damn good. However sensing this she told me to calm down and sat on the side of the tub. beckoning me to her pussy i needed no invitation and buried my head in her pussy licking and sucking on her clit i felt her hips jerk and knew how much she must have been enjoying it.  Without notice she turned over and tld me to get up. I stood up and she grapped my dick she then spositioned it over her arsehole. She demanded me to shag her up tthe arse. I slowly pushed the head and once it was all the way in i knew i could start to pump her ass. After a few slow thrusts she begged me to shag her harder so i upped the pace causing her to moan louder and start to finger her pussy in rhythm with my thrusts.  after her sucking previousl;y it was no surprise that within a couple of minutes of banging her ass i erupted with a huge load of cum filling her sexy ass i then pulled out and allowed her to lick the cum off my dick but she started to suck and within seconds i was unbelievingly hard again she then beckoned me to fuck her pussy as she lay on a deck chair. without protection but not caring i eased my dick in and strarted to pound her pussy as she screamed in delight until i felt my self ready to cum and even though i warned she said she didnt care. on hearing those words i released another load of cum and as i pulled out spurted some more on belly and as she shoved my cock in her mouth another spurtr of cum hit the back of her throat. we lay down and continued to kiss.  Since that holiday we have two kids and continue to shag however the closest we get to a jacuzzi is the bath. Myself and mark havent spoke in years.
