Back-on to their father who was seated with wife beside him, the girls sat facing me, glancing at each other and then to their own bodies as they continued applying their sunscreen. There I sat, in my mind I was mouth-gaped-open, but in reality I sat stoic with my head down, feigning that I was reading, eyes strained from peering up and over my glasses at them. I had hoped I was not so conspicuous, but somehow these two knew I was perving over them. My pants quietly buzzing with the vibrating pocket pussy keeping me so so hard. I shifted to try and alleviate the pressure but moving it just made it feel better. I could feel the vibrations through my entire pelvis.
My mouth was going dry as I stared uncontrollably at the sight of sweet young underboob. 18-year-olds had the most amazing bodies. Teen 1 had incredibly hard nips, poking out so far they made a shadow under the mid-day sun. Teen 2 with the underboob kept moving her hand too close to her thin bikini top and kept inching it further up, now starting to show some areola. A ruckus behind them briefly shot me back to reality. The mother had suddenly got violently ill and rushed off with the father to their cabin. On their way out, the father not even glancing back at his scantily clad teens, shouted, "Watch ur brother. We'll be back later". And then we were alone.
I couldn't help but be drawn into the commotion. I realized I was visually watching the door where they left, I glanced back to the girls who were staring at me devilishly, smirking. I shyly shot my head down again, trying to resist getting too turned on. I'd just have to NOT watch them. But it was ridiculously hard. While lil bro had run off to the far end of the deck, Teen 2 gasped as she held a handful of sunscreen lotion, she squirted out waaaayyyyyyy too much, I was intrigued and found myself staring again. She giggled with her sister and slapped some excess lotion on her leg, the began rubbing it in. Teen 1 picking up some and doing the same to her sister. FUCK! I had to watch them practically grope each other, their skin was now so shiny, glistening under the sunshine.
I tried one last time to seem uninterested; pretending to raise my head, see them and bury my head in my book again. Whether they believed me or just wanted to have more fun, the continued soliciting me from across the way. Even if I truly wasn't enticed, the buzzing around my cock would have kept me engaged. My eyes were darting back and forth, from T1s pokies to T2s underboob, now so revealing her nipple was about to make an appearance. They then turned up the tease. T1 reclined her chair, lying on her front, unclasping the bikini top and handing her sister the lotion. T2 obliged, applying the smooth cream to her bank, slowly spreading it around, down the small of the back. Then onto the part of the cheeks that were revealed by the skimpy bikini bottoms.
Her hand pushing the bottoms closer to the center, showing off more of her sister's bum. Her feet were pointing to me, I had a clear view of her crotch, she spread her legs to allow her sister the finish lotioning up her inner thighs. I was certain she had already applied lotion to the full of her own legs but was not disappointed. It appeared as if T2 was now groping her sister! Her hands were really rubbing in the cream in between he sister's juicy thighs. I couldn't be certain from the angle but I suspect her hand touched off her sister's pussy at least once!! I was enthralled, wanting so bad to just yank down my pants and go to town on my desperate, throbbing dick. At least I was being stimulated in some regard, the buzzing now subsiding to a droning "hummmmmmm" ... Seems my dick was used to the feel now.
Then I felt the rhythm change, the pocket pussy was speeding up, increasing the vibration mysteriously. It was the boy, he found the remote I stranded across the deck from me, and was pretending it was a gun - shooting his sisters. The sisters never noticed this, but I was now being teased much worse than before, I feared I would be too enticed and explored in my pants, then I'd be screwed with a huge stain on front of my shorts and no easy way to conceal it. I'd have to try not to be too turned on, it's all I can do. The sisters were making it tough, after scolding their brother and confiscating the remote, they sent him back to their room. After fiddling with the knobs and gauging my reaction to it they figured out what I was up to and made it their mission to torture me as much as they could. I wanted to admit what I was doing and just end it all, but I was in too deep. I'd surely get charged with something, public indecency, lude behaviour...nothing I wanted to be convicted of!
