Show him her ass

Beth really wanted to grab Billy's tight little ass, but she held back. She didn't want to scare him off.

"Billy boy," she called, "could you give me a hand with my bag, son?"

"Why sure thing, ma'am" he replied, heading back, "where is it?"

"Just here, by the door," Beth answered - and seeing that she had the young man's attention, she turned and bent at the waist to pick up the case that she had brought with her. Beth smiled to herself when she heard Billy's sharp intake of breath as she bent over.

For his part, poor innocent Billy didn't know where to look. Beth was 10 years older than his mother, but Billy's mom would never wear a skirt like that. As Beth bent over, that tiny skirt rode up the little bit of thigh that it was covering revealing Beth's gorgeous black ass and just the hint of a thin white thong between her cheeks. Billy tried to ignore Beth's ass cheeks and her long sexy legs as he ran past her to help with her bag.

As he turned round and bent down to face her, Billy found himself instead looking straight down her tight top and into Beth's spectacular cleavage. Her pendulous breasts jiggled as she (deliberately) struggled with her case. Her nipples pressed against the thin material of her skimpy top, sticking out like organ stops. To his great shame and horror Billy felt himself stiffen.

"My, my," said Beth, looking up, "we are a big boy, aren't we son?"
