Walking the isle on an inward bound flight from Singapore to London, I caught a teenage boy jacking-off to a hand-held device, showing porn.The isle w...s dark so it was easy to spot him through the illumination from his 4" screen and badly placed blanket.His pants were at his ankles and his bare ass was visable, side on, as the blanket had shifted to expose hid flank.He was in the second back row, beside the galleys, and only a girl was on the same row but across the isle, streched out and. She was wearing a sheer white camisole that fitted tightly around her torso and cupped her round, perky breasts. It was fashioned from a see-through material, with the exception of the area directly covering her nipples. Her little white boy-short style panties completed the matching set. "Very nice," I complimented, scanning her body with lustful eyes. "Wait," Sue blurted with excitement. "You have to see the best part!" My girlfriend had obviously enjoyed herself by dressing her friend up. He came over and stood behind me, slipping his hands over my hips as we both looked in the mirror. “That material feels soft and wonderful,” he said, “and there’s a gorgeous body underneath it.”I could feel his hard cock brushing against my bum and his hands started to explore the silk, slowly moving up, tracing the outline of my nipples through the lace trim. I arched my back slightly as he brushed over the fabric, slowly running his fingers around the bottom of my breasts, gently cupping them. I grabbed the wetteen, feeling our bodies slip and slide against each other as we made outwith Bryan watching. "OK, I need to stop." I said as I suddenly pulled back, regaining mycomposure. Bryan was grinning from ear to ear under the spray of theshower as he stroked his hard boy cock watching us. "You're going to get me all worked up again." I smiled at Leif. Hegiggled then turned around to face Bryan. "Did you hear that Bry? I need to clean you up." Leif said. He thenspun.
