Suddenly the boy sitting closest to Ellen turned and she immediately recognized him as Phil, Bob's brother. Ellen remembered Bob's comment earlier about Jennifer probably making out behind some sand dune with his brother, and she almost gasped when she realized how true Bob's sarcastic remarks really were. Yes, her sister really must be troubled to be doing this and loving it the way she was. She watched as Jennifer's hand clenched around the long expanding rod of Phil's cock, and she flinched as she heard a trio of groans rise up from the dim moonlight lit forms below. The two men's hands moved in sensuous arcs across Jennifer's breasts bringing out stronger moans from the voluptuous young girl who seemed as though she were about to break into swoons of ecstasy any minute.

Phil's head bent toward Jennifer's round full breast and his tongue slid out of his mouth and began licking at one of the pink erect nipples. His head seemed to move in tiny circles around it, and Ellen could hear wet sucking sounds and further mewls of pleasure spilling from her sister's lips. Jennifer's stomach arched up and wriggled obscenely as though to lift her breasts closer to the tantalizing fingers and warmly moist lips pulling and sucking at the pink tipped buds of her breasts. Yes, Ellen thought, there was no doubt about it, Jennifer was definitely enjoying this, and she acted as though she had done this with other men many times before. The younger sister clenched her hands in the sand as tears of rage and confusion welled up and flooded her eyes. Now there was nothing she could do but watch and remember this moment which was already etched indelibly into her mind like a painful scar she couldn't get rid of.

Down below the watching girl, Phil moved his hand over the erect little nipples of Jennifer's breast, while the other man, who seemed a few years older, caressed the rounded plane of her nakedly exposed belly, and thrust his fingers in a smooth motion beneath the girl's bikini panties.
