Lynn and I got back into the pool ( while Amber laid on the lounger ) to cool down, but that had absolutely no effect on my stiff cock. She still had her 2-piece on and 2 min later, asked me if I'm ready to continue. I got out first , went t lay on the 2nd lounger next to Amber. Lynn followed afterward, stood in front of me and took her top off first. Once again I found myself staring upward, looking at her piercing nipples and " handful " breasts. She sat on my chest facing me and spread her legs over the sides of the lounger and leaned backward. Amber was laying there watching and said : " look at that - you are going to be so surprised ". That wet tight clinging see-though white bikini , pulled upward through her slit as she leaned further backward. She moved forward until she was practically on my chin and said : I want you all to myself, no distractions ". I gently loosed the side straps and just stared. Bigger clean shaven pussy and wider hole. " She's big, isn't she " said Amber. " Do to her what you did to me " Stick you tongue out, let her move back and forth. Eat her out good." As I was eating her out, I could feel my cock throbbing, this time there was no one deepthroating or sucking me. I could feel my tongue slipping in and out, in and out, She wiggled in a circular motion , her pussy buried in my face saying : "deeper, harder, eat me out ". This is where it becomes interesting . I was munching away and my cock throbbing so much and as stiff as can be , I never heard the patio door opening, the one that leads to the pool. There she was, staring at the 2 of us - Lynn's uncle's step daughter ( 17 years old, final school year ). I got such a hell of a fright, I jumped up and she was staring at my throbbing cock. Amber, the " pussy eater " among us, also got up, naked as can be and said to her : I won't tell, if you won't. Shockingly the step-daughter said : " ok , on one condition. Can I join in ? " Amber said : We are first going to undress you till you in your underwear. then we are going to wet you, so that we can have an idea what's underneath there before we decide what to do. " Susan stood there, soaking wet in her pale blue 2-piece underwear, medium to large breasts with piercing nipples too and I thought I was going to explode when I saw what was between the legs. Beetle bonnet, clean shaven and when we asked her to open her legs slightly, The size of her hold drove me wild and I thought " how could someone this skinny be this big . Before I continue the final chapter, let me confirm : Amber is the "pussy eater" Lynn loves facesitting and 69 position - eats pussy too and loves to be eaten , but loves to suck cock more Me, I just went along So this is how our day ended. Are you ready ? We had a marathon oral ONLY foursome in this position : Susan laid on her back facing the back on the lounger, legs in an upright position, her butt slightly above the back on the lounger, in a splits position, pussy gaping wide open and her massive hole exposed. I'm standing, my legs over the side of the lounger, behind Susan's head Lynn stretched out and placed her hands gripping the back on the couch, her legs on my shoulders Amber is at the back of the couch, staring down Susan's gaping hole. " I'll go first " - she bent down , does what she's best at ( eating pussy ) - slides her tongue deep down her hole, wiggling, twisting , eating her out. I guided my swollen stiff cock into Susan's mouth, She would do 3 lengthy strokes, take it out, suck my balls a little, put it back in her mouth, sucking slightly harder and play with my balls. so it repeated. 3 lengthy strokes, take it out, suck my balls, put it back in and suck a bit harder. It drove me insane. What was I doing ? Lynn lifted slightly, my face right up against her pussy. " see you far you can slide it in , eat me out. I was eating pussy like there's no tomorrow. again she said : take it out, side it across both holes, tease the other hole, slide it back inside again, eat me out ". And finally : Lynn had front row seat as Amber was eating out Susan. I could hear Amber slurping away as she was been eaten out, and then Amber and Lynn decided to take turns. Amber is eating her out and slurping, removes her tongue, Lynn plunges her tongue even deeper, eating and slurping.. I could feel Susan gripping my balls, and the more she's moaning, the faster and harder the sucking. I eventually just exploded in her mouth, Amber and Lynn looked at me, smiled and said " Well done Susan " " It's pussy time " both Amber and Lynn shouted and they ate pussy like there was no tomorrow.
