Sam thought about what was happening as he drove. He did tried to call his father's bluff, but his dad seemed to be pushing them toward something he could dreamed about occasionally as he beat off. That was petting his sister and getting to see her naked. He felt his prick begin to fill with blood. Who knew what might happen? He would just ride along and see. They got to his favorite spot and he parked, turning off the lights. He already had the radio on and he got out his favorite make-out CD and put it in the player. He sat there, not knowing what to do.
"See? This isn't so bad, Daddy," said Chrissy. "I still don't understand what all the fuss is about."
Stephen leaned forward from the darkness in the back seat. "Sam, is that all you do when you bring a girl out here? You just sit?"
"Well no," said Sam. "I usually try to ..." He dropped off. He didn't want to admit that he usually tried to get into the girl's panties.
"What do you try to do Sam?" said his dad. "Come on. Chrissy needs to know."
"Well I kiss them ... and touch them ..." He didn't add, "if they'll let me."
"Okay then, get to it. Show her what boys do."
Sam couldn't cope with the stress. He was trying to be two people at the same time.
About then Chrissy tipped her head up and whispered in his ear, "Aren't you going to kiss me Sam?" She was trying to call someone's bluff too.
So Sam kissed her. In his confusion, he kissed her like he did kiss any girl. Definitely not like he kiss his sister. But she felt like a girl, and she smelled like a girl and within 15 seconds she was kissing like she had done it plenty of times.
As for Chrissy, when her brother kissed her like that, like they did in the movies, she felt weak all over. It made her feel funny in her stomach. No, not in her stomach, but down there somewhere. She decided she liked this kissing stuff. When she felt his tongue slip into her mouth, all slippery and smooth, the feeling "down there" got more intense.
When she kissed him back, and gave him some tongue in return for his own, Sam went on auto pilot. His hands began to stroke her back, moving to her arms, caressing her hair. Now he kissed her cheeks and neck, nibbling on her ear lobe. She shuddered, a good sign, and he kissed her again as he decided to see what her young breasts felt like.
When Sam's hand came around her elbow and cupped her breast through the halter top, Chrissy almost stopped breathing. What was he doing? Boys weren't supposed to do that. She broke the kiss. "Sam!" she said.
"Aw, come on. I won't hurt you. You just look so hot and you feel so soft."
He went back to kissing her.
Chrissy felt all muzzy inside. She felt a thrill shoot through her when he said she looked hot. And his kisses were so wonderful. What could it hurt to let him feel her boobs a little? When his hand slid over her breast again, she pressed it into his hand. It did feel good. She was enjoying a kiss when she realized his fingers were pinching and rubbing her nipple. And that felt really good. Then, somehow, his hand slipped inside her halter top and now he was fondling her naked breast. Now he thrummed her nipple. She felt a sharp stab of pleasure between her legs. She thought that was very odd, but if felt good too.
"Chrissy?" he said as they paused to breathe.
"Hmm?" she said back.
"Can I see them?"
She knew exactly what he was talking about, because his hand was still there, still squeezing and roving around her breast. He had got in through the side of the halter top. But she wanted to tease him for some reason.
"See what Sam?" She arched her chest, pushing the breast into his hand.
"I want to see your titties," he said. "I bet they're beautiful."
"You've seen my boobs before, you ninny," she giggled. "Remember that time when I was in the shower and you had to pee so bad and you couldn't wait and you barged in? You saw them then."
"Yeah," he said. "But I never got to really look at them."
"Chrissy," said their dad, startling them both. They had forgotten he was back there. "Take off your top. That's what the boys will want you to do on dates."
Chrissy reached behind her neck and untied the knot in the halter top. It slipped down her chest and her perfect pale orbs were exposed.
"Oh shit," said Sam. "They really are beautiful." Then his head dipped and he sucked in a nipple.
"Sam!" his sister squealed. "You can't ... ohhhhhh ... you shouldn't ... ummmmm ... oh, Sam, that feels nice." She lay back as his mouth made love to one and then the other turgid nipple. This was really nice and it kept making her pussy feel so warm and wet, just like when she was washing it extra good in the shower.
Sam started running his hand from Chrissy's knee up her thigh and then back down. Her skirt was so short he could almost touch her panties without going under the skirt at all. Her legs weren't closed, but they weren't gaping open either. He let his hand go higher ... higher ... higher ... and then he hit panties.
Chrissy felt his hand moving all over her thighs. It was a new feeling. It was nice, but scary at the same time.
"Sam? What are you doing now Sam?" she said breathlessly.
"I'm just feeling you a little," he said and went back to licking and sucking her nipples.
"I don't think you're supposed to do that, Sam," she sighed. "You shouldn't touch me ... there."
There was a gasp from the back seat, and the sound of a zipper being drawn. Her father's voice was clear when he spoke. "Chrissy, you're here to learn what boys want. Whatever he wants to do, you let him. You need to know what things feel like."
Sam's hand immediately rose to cup her pussy through her panties. He pressed his fingers into her sex and rubbed them in a slow circle.
Chrissy gasped as her brother's hand slapped against her pussy. No boy had ever touched her there, and it felt different. Then he rubbed and electricity shot through her, only this time it went from there to her nipples! She spread her legs almost unconsciously, to give him more room. Now he lifted his head and kissed her again, a long tongue swapping kiss as he rubbed her. Her pussy felt hot ... sticky ... good. She knew he was going to slip his fingers into her panties ... knew he was going to touch her pussy with his fingers. She knew her pussy would make his fingers wet.
She couldn't wait.
She spread her legs wider.
