PART 1
Jason stopped stroking his cock as he heard the back door slam downstairs. He was lying naked in the bath, wanking his cock as he thought about the various girls at the new university he was attending in varying states of undress. Having just turned 18 only three months previously, he had been looking forward to a lazy year off, but had instead been sent to stay with his aunt. Apparently, she was stricter than his mother and was supposed to straighten him out. Jason squeezed the base of his cock as he felt the familiar rise of semen from his balls, but he wasn't quite ready to cum yet. His ears were now the most alert part of his anatomy as he listened to his Aunt Maggie's footsteps on the stairs. She was a woman of great drive who always moved with purpose and today was no exception. Jason held his cock tightly as he prayed she was heading straight for her bedroom and not coming into the bathroom. This was an old house with no lock on the door.
His worst fears were realised as he heard the latch of the bathroom door open and his aunt start to walk in. Quickly, he removed his hand from his cock, so that she wouldn't think he'd been masturbating, rather clumsily leaving his erect penis in full view.
"Oh," she said, "you're up here." The door to the bathroom was behind and to the left of the bath and so Jason turned his head back to look at his aunt. She was quite a striking woman, but in a plain, rather restrained way. She had short, dark hair and always dressed conservatively, but Jason had noticed that she had quite a decent body, including a very nice pair of 34D breasts. Later, he would stand at the door and feel a real thrill as he realised that his aunt had had a perfect view of his naked body from where she was standing.
"Yes, I'm up here," he said.
