A gentle rocking of the car, a shifting and rustling in the back seat, momentarily intruded into Charlie's consciousness. Then he ignored everything but the building pleasure in his crotch. He concentrated on the hot pool of cum in his groin, and the blazing nerve endings in his cock, and the hot milking envelope around his fingers. With his thumb he sought Jan's clitoris and pressed down on it. He felt it squirm aside. Following it, he squeezed the turgid rod of nerves against her pubic arch and felt it squirt away like a watermelon seed.
'Awwww,' Jan whined softly as he again trapped her clit under his thumb. She pumped his cock faster and harder, sliding her hand under his testicles, probing back under the wrinkled bag holding them. She scratched and poked the ridge between his scrotum and anus.
Charlie squirmed his ass forward and rocked his pelvis up to give her better access to him. Her finger pried farther back, and jabbed at the dimple of his asshole, and fire roared through his guts. His muscles convulsed and heaved in reaction to the incredible unexpected probe.
He was going to cum. He was going to cum. The itch, the ache, the burning all melted together into a hot fireball of pleasure that spasmed and pulsed, then swelled and contracted. It ejected hot gobs that seared the length of his tightly squeezed cock. The searing fluid spurted, erupted, and spattered down on his belly, his thighs, and Jan's hands and arms. She kept pumping and pumping and pumping his cock, milking it and milking it with her fingers, and twisted her finger at the gate of his anus. The scratching of her fingernail there lashed through him like a delicious twisting, curling lightning bolt.
He rammed his thumb on her clit and rolled it more frantically against her pubic arch. He was mindlessly squeezing her breast, hard enough to bruise it. He was pumping three fingers in her vagina. He felt her tissues fountaining around his hand. She was whining and whimpering, her body quivering in the throes of an orgasm as he sprayed his thick semen over them both.
Everything in the car faded out in the haze of pleasure, and returned gradually as his ecstasy receded. He felt limp and drained and totally satisfied.
The air in the front of the car was thick with the smell of sex as he and Jan untangled themselves. She licked his semen off her hands and arms while he got a paper towel from the glove compartment, dried his hands and dabbed his thighs and stomach.
'How's everybody back there?' Jan asked. She was still nude. She turned and rested her hands and chin, on the back of the seat.
'Okay,' Cookie answered sullenly.
'Enjoy the movie?' Jan teased.
'Oh, is there a movie tonight?' Mike asked. Cookie jabbed him in the ribs with her elbow.
'Ready to leave?' Charlie asked.
Jan turned with a jerky motion that made her breasts jiggle. 'You might wait until I get dressed,' she said brazenly.
'Are you naked?' Mike asked.
'Of course I am, dummy.'
'Let's get out of here. I'm hungry,' Cookie said quickly.
'Okay,' Jan agreed, lifting her ass off the seat and pulling her pants up. 'Take it away, Charlie.'
He was trying to look in three directions at once as he started the car, replaced the speaker on the pole, and tried to catch one last glimpse of Jan's great breasts.
He wondered what Cookie was so uptight about. Maybe Mike had been more cloddy than usual and had hurt her, or something. If he had done anything bad, Charlie swore he'd make the little twerp regret it. Cookie might be a pain in the ass at times, but she was his sister and he intended to take care of her.
As they pulled out of the drive-in, Jan was combing her fingers through the black curls that tickled her neck. 'Got cum in my hair,' she observed. 'It combs out easily, once it dries.'
Charlie's sweaty hands squirmed on the steering wheel. After stopping for a snack, he dropped Jan and Mike off, and he and Cookie headed for home. She climbed over into the front seat and scrunched down next to the door.
'You okay, Sis?'
'What do you care?' she sniffed. 'You and Jan sure had a hot time tonight.'
'Yeah, well, not a word to Mom and Dad, remember?' Charlie reminded her, nettled.
'You going to see her again?'
'Sure am,' Charlie said enthusiastically. 'She said she wanted to see me again soon.'
Cookie muttered something under her breath that he didn't catch. He glanced over at her. She was staring sullenly out the side window. He wondered what she was so upset about. He was determined to find out if Mike had hurt her or what.
'You okay?' he asked again.
'Yeah!' she said curtly.
Put off by her sharp response, Charlie let the matter drop for the time being, and thought about Jan. She really wanted to see him again. If this was a first date, what would she do on the second? His exhausted cock stirred slightly.
He wondered what had happened between his sister and Mike.
CHAPTER II
'No, Mike!' Cookie protested feebly, as his hand pressed down on her small breast through her blouse and bra. 'Oooohh, Mike,' she groaned, her fingers closing around his wrist. She wasn't trying to lift his hand off her anymore.
A tidal wave of unfamiliar sensations raged through Cookie's eighteen-year-old body. Her nipples, tiny little pink buds, ached as they stabbed impatiently into the cups of her bra. Her insides felt all achy and weak and quivery. Between her slender tan thighs her shorts were bunched up in her crotch, making her feel all hot and damp and sticky and hungry and empty and itchy.
Suddenly Mike's mouth was pressing down on hers, and his tongue was wedging into her mouth. Her resistance was changing to acceptance as wave after wave of a thrilling new feeling raged through her maturing body. She had never felt anything like it in her life. She clung to Mike desperately as she was tossed on the storm waves of newly kindled sexual excitement. His hand squeezed her breast through her clothes, and it hurt, but it felt so good, so wonderfully, incredibly good, too.
Percolating dimly through the seething haze, increasing Cookie's building passion, were the sounds from the front seat. She could hear Charlie, groaning softly, steadily. Also, there was a wet sucking noise. Cookie wondered vaguely what Charlie and Jan were doing. Then Mike's fingers were on the top button of her blouse, and her fear surged upward.
'No, Mike,' she pleaded weakly, uncertainly. Oh, God, how could she be afraid of anything that felt so incredibly good?
The drive-in's loudspeaker rattled and squawked unintelligibly. On the big screen, in full color, bodies writhed, flesh met flesh in a tight, lewd tangle.
Cookie wasn't watching-she didn't need to-she was living it! Mike was unbuttoning her blouse-he was undressing her! And she wanted him to! She wanted to be free of her suffocating, restricting clothes. She wanted to feel cool air and his hot hands all over her naked breasts.
Only she didn't, either. What if someone came by and shone a flashlight into the car? She'd die with shame if anyone saw her breasts. Charlie had said this was the safest drive-in in town, but what if he was wrong? What if a cop came along and caught her like this with Mike?
She leaned forward enough to let Mike ease a hand between her back and the seat, up under her loose blouse. His other hand was desperately clutching her breast through the thin cotton of her demure bra. She could actually feel the weave of the fabric as he scrubbed it across her burning nipple, could feel the material wrinkling as he squeezed her tender little mound.
When she had brought the bra, it had been a little big. Now it felt too small. The breast that wasn't being tormented by Mike's hand was aching and swollen, demanding some attention for itself.
