I asked her if we shouldn't go to the school board and claim sexual harassment or something, but Mom said, "Honey, that will take too long. By the tim... it's resolved, you would probably miss your junior year on the squad. Sorry babe, the rules have changed, and we have to change with it."Anyway, that night, while I was working on my homework... and yes, wiseass, I do occasionally do my homework... Mom came into my room and started pawing through my underwear drawer."Mom, what are you doing?". “All right Debbie! It’s not as ‘eavy as it was. Let’s mek a run fer it!” The two girls were soon flying along in the rain toward Waterstone House. The weather was cruel that evening however for no sooner were they a few minutes on their way when the rain increased in intensity to a drenching downpour. Within a few hundred yards they were soaked to the skin, their clothes hanging on them in sodden rags. To compound their misery Debra, in her haste, stumbled and fell on the dirt track leading. She instinctively began to pull away when she felt his strong hands on her hips. He was so small it didn’t hurt at all. He pumped slowly and gently. The sensation of her orgasm and the anal stimulation got the better of her and Marcia came again. It built up slowly and gradually became the best one of the night. He continued his slow pumping and finally gave the jerk that told her he was coming. He started to pull out when Marcia reached behind her and held him firmly in place. She felt his. The night came and he came home expecting to start tea, he was surprised all was set and he sat there waiting. He ate his dinner and relaxed whilst we got ready for our dance.We started the music and danced away out costumes where flimsy and left nothing to the imagination, being 18 now I had a full figure and my sister was 16 and well developed, I moved towards dad, moving sexy he watched as his eyes where fixed on my tits I looked down to see a huge lump in his trousers, my sister noticed.
