The girl had always thought he was the most handsome man she'd ever seen, and it really excited her to know that the sight of her sexy young body had given him an erection. Robin had only seen it poking out against the front of his pants, but she tried to visualize what his naked cock really looked like. The only prick she'd ever touched was Mark's, but after seeing Frank Boswell's much bigger cock when he was fucking her mother, Robin was very curious about the differences in men's dicks.

For the last few evenings when she was sucking Mark off on the patio, she pretended it was Bill Morgan shooting cum into her mouth. Not that she didn't like Mark, it was just that she was obsessed with thoughts of the older man's prick.

Walking down the sidewalk one afternoon, Robin ran into Kay Morgan. After they'd been chatting for three or four minutes, the woman suddenly asked Robin if she and Mark would like to drop over to her house some evening.

"Why?" asked Robin, surprised that adults would invite a couple of teens over.

"My husband thinks you're awfully cute," smiled Kay.

"Really," grinned the blonde, visions of Bill Morgan's hard cock popping into her mind.

"Yes, really," said Kay, seeing the pleased expression in the girl's eyes. "We'd both like to know you better."

"When would you like to have us?" asked Robin, thinking how exciting it would be to spend a whole evening with the handsome man.

"How about next Friday?"

"Okay," the girl beamed. "That sounds neat."

The following evening when Robin's mother was out of town on one of her overnight business trips, the pretty girl was lying naked on her as she lazily fingered her juicy twat. The thought of being with Bill Morgan next Friday night had really turned her on. Robin had remained a virgin because she was a bit wary about having a hard dick shoved into her unused cunt, but since she'd discovered how nice it felt to stroke and suck on Mark's cock, the idea of fucking was beginning to appeal to the girl.
