It was a hot, clear Saturday in early spring. The sunlight bathed the earth, warming the winding streets and manicured, middle-class houses. Children frolicked on the sidewalk, husbands mowed their lawns, old women tended their backyard gardens. It was a better than average weekend in the suburbs.

Trisha lay on her back by the patio swimming pool, sunning herself on a terry cloth blanket. A whole year had passed since she had first seen her parents fucking through the hole in the closet wall. She was older now, the homecoming queen, the prettiest senior in her high school.

The maturation process had treated Trisha extremely well. If she had been pretty before, she was truly gorgeous now. Her legs and hips had filled out, becoming even more shapely. Her exceptionally large, full tits could barely fit into her bra. Trisha was wearing a skimpy bikini, and it was a good thing that her backyard patio was enclosed by a tall picket fence. Nearly any man seeing so much of her tawny, luscious flesh would have had to jack off.

Today Trisha was feeling even hornier than usual. As she lay on the terry cloth towel it was difficult not to squirm, to spread her legs and wriggle her ass and stroke the aching lips of her wet young pussy through the crotch of her bikini.

Her brother Ralph was coming home from college in a week. Trisha hadn't seen him for a year, since the conclusion of their two week marathon fuck and suck orgy, held behind their parents' backs until the very day of his departure. Trisha tried to imagine how her brother might have changed, and groaned with desire. She wanted to suck his big cock again so much she could hardly stand it.

She hadn't fucked anyone since him, not in a whole year. The boys her age were too silly and immature for her to go out with. All they ever wanted to do was neck in the back seats of their cars, and they always came in their pants before Trisha could get down to screwing. She had given up on them quickly, and in her innocence had never thought of anyone else to satisfy her wanton cravings.
