With his heart pounding in his chest, Vince waited for his knock to be answered. After what seemed like hours the door was partially open and Kathy was standing there staring at him. Kathy was not as stunning as her older sister but she was still very attractive.
"Did you forget? Mandy's not home," she told him in a soft voice.
"I know. I came to see you," Vince managed to say.
At his statement, Kathy's nipples became very prominent from under her loose-fitting scrub shirt. She blushed as she took a gulp of air.
"Downstairs," was all she said as she opened the door wide and disappeared through the kitchen.
Vince closed the door behind him before he headed down to the basement. Once there, he switched on the recessed lights and took a seat on the couch. As he waited he began to question himself and his actions.
"What are you doing here? For all you know, she's calling the police," he told himself as he imagined what she would tell them.
"My sister's boyfriend is here. I think he wants to fuck me," she would say in a soft trembling voice.
"Perhaps she's not calling the police, she's calling her sister instead," his mind told him. "Vince is here. I think he wants to stuff his hard cock in me."
He resisted the urge to run and continued to wait. He waited for a goodly amount of time until he finally he saw her shadow on the walls leading to the basement. When she reached the bottom of the stairs Vince's mouth hung open. In her absence, she had done her hair and makeup and donned a short white slip and matching bra.
As she moved toward him he also noted that she had also covered her tiny feet with white high heels. As she took a seat next to him her perfume enveloped him. Kathy turned at the waist so that she was now facing him and slowly wrapped her arms around him.
Vince's cock became even harder as her soft pink lips touched his. He responded by wrapping his arms around her and allowing his hand to feel the warm soft flesh of her bare midsection. The touch of his hands against her flesh caused her to hold him tighter and push her tongue into his mouth.
Vince could not believe the passion in her kiss or how much it turned him on. They both leaned back into the cushions and he released one arm from his embrace. He then allowed the hand of his now-free arm to run across her silky bra cups and then down the front of her half slip.
Kathy broke the kiss and rested her head on one shoulder as she placed her lips very close to his ear.
"Oh yes," she said in a breathy whisper. "Touch me."
Vince directed his hand to slide down her silky legs and then under the hem of her slip. His fingers encountered the crotch of a pair of tiny panties that were very wet. He could feel her body shiver and she moaned slightly at this movement. She, however, stopped his hand from massaging her pussy through the silky cloth.
"Take your clothes off," she requested as she released him from her embrace.
In record time Vince removed his shirt and pants. Once his clothing was discarded Kathy commenced to run her hands across his naked chest, arms and legs in between planting kisses on his flesh. She then gently touched his hard cock through his briefs and moaned at the feel on it.
"My family thinks I'm crazy or distant because I'm not as outgoing as Mandy," she told him as she fished his hard cock out of his briefs. " I have the same desires as she does but I prefer to keep them to myself. Do you know that after I watch you fucking Mandy, I head to my room to finish myself?"
In Vince's mind, he saw her on her bed with her legs spread masturbating and it served to get him even more excited.
Kathy then stood up and Vince watched as her hands slipped under her slip and removed a pair of bikini panties. She then departed upstairs for a moment. She returned shortly and embraced him again.
