His sister opens the stall door

As John reached for the TP, he saw the door of the stall being kicked open by his younger sister. Immediately, he berated himself for not locking the door, but had little time to do so as he saw her standing there with two of her very hot friends, Samantha and Kia. He tried to cover himself but it was too late.

“Well, well, if it isn’t my TINY bro! I guess it really is TINY SISTER now, though, isn’t it?”

John stammered as he trued to get her to stop, “Please! No! It’s not what you think! It’s all they had after my pants ripped!” The raucous laughter of his sister and her friends set him back on the edge again.

“...oh god,” he moaned.

Several drips hit the floor of the bathroom, ringing out like nails across the linoleum.

“No fucking way!” “Did he...?”

“Shame, shame, little sis. Making a mess like that everywhere. Show us. Show us the mess you made.”

He hadn’t actually cum yet, it was a Herculean feat in his eyes. But the girls’ laughter was just enough to make him squirt a jet of pre onto the floor. His attention turned back to his sister, who’s hand was now wrapped around his throat.

“I said, show us, sissy!”

John immediately lifted the front of his cheerleading skirt and closed his eyes. He could hear them inhale, like they were preparing to gasp.
