Especially during the summer season the swimming pools use to be full of c***dren of the ages of 10-17. The life guard was also an unofficial swimming...instructor. He was a small built guy dark but an excellent swimmer. I was 5.10 then athletic body, fair and my sister was 4.6 slim and a little dark which was a regular subject on which I teased her. I was a swimmer but this was her first year at the pool and I was made responsible of teaching her swimming.It was the beginning of the summer. "If you weren't so pathetically repentant, I'd suspect that you weredoing this on purpose," Michelle giggled.The booze had lowered their inhibitions. "You're getting a bit hands on there darling," Michelle joked."Well only because I've got this big arse pushing into me," Johnsqueezed her buttock."Are you saying I have big arse!" Michelle pushed her bum back againsthim and wriggled."I'll have you know, men have fought and died over my derriere!" shelaughed."What these?" John took both of. He reaches for her tube top and with one deft motion lifts it above her head and off. She stands before him now only in heels and her skirt, her supple 34B bosom heaving. He begins to kiss her exposed nipples. Working one with his hand, while he tongues the other.Alternating between nipples, he reaches under her skirt once more, and slides two fingers over her bare mound, caressing her tender clit, working her up into quite a frenzy. Her head falls back, mouth open, slightly biting her tongue. I could feel the heat of their stares and imagined those red dots you see on films and television when a sniper has a target in his sights, and I wondered how many dots would be centered on the gusset of my undies at that very second.I leaned back against the bench and tried to appear casual, nonchalant and without a care in the world while I spread my thighs and tried to give my audience the best view I could. Despite my careless attitude, arms spread across the back of the bench, I felt.
