Although her relationship with Billy and Karen had always been close, they were now much closer than ever before. Open affection between her and the children increased, and there was an obvious interest going on between Karen and her brother.

Karen was becoming a tease with her brother, something she had not been before. She was deliberately careless in her posture and dress when Billy was around. Susan was quick to notice her daughter would sit in positions that would allow her to expose her inviting, slim 4:34 AMthighs, her enticing body. It was an open invitation for Billy, Susan knew, and it thrilled her. It was very obvious to Susan that her daughter was trying to develop something between her and her brother.

She found it exciting to watch her slim, ever-so-innocent-looking daughter tempt her brother sexually. There was no reason to tease or tempt him, because Susan would have given them all the help and encouragement they needed, but the fun would be gone from it. Susan loved to tease and it appeared that Karen did too.

On this morning, Karen did not dress after getting up. She wore her short baby doll gown,with just a pair of matching bikini panties underneath, nothing else. Her small, luscious tits were revealed through the thin, gauzy fabric, the pink nipples showing plainly. She bounced happily about the kitchen, preparing herself a late breakfast. Susan watched, amused and excited, as Billy looked at his sister's body, her flashing slender thighs and the sweet swell of her tight, little ass.

Billy was wearing a pair of swim trunks with loose legs, and Susan found it a pleasure to see his cock straining against the material.
