“Hot enough for you?”Karla’s voice made Dave look up from his computer. There was a mirror over his monitor that allowed him to see who was behind him without turning around. It was a good thing too, because he still had a hard-on from seeing Karla earlier, when she’d stopped by to ask when their parents were due home from yet another jaunt to places he couldn’t pronounce. She had still been in her nightie and her nipples had been very visible under the sheer fabric. He hadn’t figured out yet that she only wore things like that when the parents were gone. Now she had changed into a cut-off t-shirt and a pair of shorts with no legs at all, and very little seat. “Supposed to hit 105 today, according to the weather site.” He gestured at his screen and she came in and leaned over his shoulder, “accidentally” putting a breast on either side of his neck. “I think I’ll melt by the pool all day!” She pretended to swoon dramatically and landed on his bed, with the lower 1/3 of her breasts showing under the t-shirt. Her eyes were closed so Dave took the chance to get a good look at her tits. His eyes ran down her taunt belly and he saw that she was wearing a red thong under her shorts. I’m going to cum just sitting here he thought. He was 17, one year older than Karla, but he was still a virgin. He though Karla was, but she was so good looking it would have surprised him. “I wish it would cool off, I’m hot just laying here.”Dave reached a decision. He was dying of horny and no longer cared about anything. “Maybe you’d be cooler without that on?””Without what on?” She sat up and looked at him with a strange look in her eye.He couldn’t speak, he just pointed at her top.”You don’t think I’d be cooler, you istanbul travesti just want to see my tits. . . . Ok, here.” She quickly pulled her top off and lay back down on the bed with her eyes closed. Dave saw a blush spread down to the tops of her lovely breasts, already a respectable C-cup at least. The nipples were sticking up and very pink. He moved from his chair and stood over her. She didn’t open her eyes, she just said, “You can touch them if you want.”Dave needed no more encouragement. He reached out with both hands and cupped them, moving up over the nipples, feeling them push back against his hands and spring up again as his hand moved off them. His hands moved gently, lovingly over his sister’s tits, and she arched her back, pushing them into his hands. “Do you think I’d be even cooler without my shorts?” Dave couldn’t answer, but her eyes were open now and she saw him swallow hard and nod quickly. “Unbutton them and pull them off.” He sidestepped once to reach her hip-level and had her pants undone quickly. Her hands went down to hold her panties on while he pulled her last piece of outer clothing off. “No sense rushing things,” she said with a husky voice. He pulled her shorts down her legs and off her feet and tossed them aside. She took her hands off her panties and put them under her head, telling him it was okay to take her panties down now. He hooked a couple of fingers on each side of her undies and pulled slowly. Soon it was obvious that she had shaved whatever pubic hair she had developed. Then the top of her vagina came into view. Dave had the usual collection of porn and recognized her clitoris sticking out between the folds of her istanbul travestileri pussy. It was the first pussy he’d ever seen live and he stopped pulling when he got the panties down enough to get a good look. He took a long look, knowing he’d always remember that sight. “If you take them the rest of the way off I can open my legs farther.” Without further prompting he pulled them all the way off her. She sighed lightly and bent the far leg at the knee.”Touch me”, she commanded. His hand went to the top of her pubic mound and slid down to her clitoris. He tried to manipulate it like he’s seen the guys and gals on the porn sites do it, and he must not have been doing a bad job, because she moaned and lifted her hips to meet his hand. He moved lower on her pussy and started to probe between her labia. “Careful there, bro, I’m still a virgin, be gentle.” “Sure thing, sis.” His fingers were wet and slippery from the juices oozing from her, and he moved up and down to stimulate her.”Hey! Stop! This isn’t fair!””What?””I’m here buck naked and you still have your shorts on.””You know how to fix that.”She sat up, which put her head just level with his lower ribs. She hooked a hand into his waistband and pulled him to her, spreading her legs so he was between them. She unbuttoned his pants and started to unzip them. “I’d better be careful here, wouldn’t want to get anything caught in a zipper!”She worked the zipper down slowly and his stiff cock appeared out of his pants. She pushed the shorts down and sat for a second looking at his cock and balls. Then she cupped his balls gently.”This is where the cum is made?””Well, the sperm is made there, then it mixes travesti with the semen farther up. “”I can feel the little tubes!”She left the scrotum and moved to his cock. He was quite satisfied with it, seven inches long and a good six inches around. She grasp it with a hand and gave a little squeak.”It’s so hot!””Yeah, there’s a lot of blood trapped in there right now. That’s what makes it hard.”She moved up to the helmet, gently opening the small slit on the end. “…and it comes out here.” She seemed fascinated with the purple head. She leaned close to sniff it, and Dave was suddenly very glad he had showered less than an hour ago. She evidently thought it smelled okay, her tongue snaked out and licked the end of his cock. “If you keep doing that I’m going to make a mess,” he warned.”I want to see that!” She moved her hand up and down on his cock, telling him she’d been watching a bit of porn herself. She licked at his cock and he just couldn’t stand it any more. His cum roared out and splashed against his chest. “Oooh, that looks good!” Karla’s lips moved to his chest and she lapped up the dripping juices.”Umm, salty! They were right.” He made a mental note to find out who “they” were, but later.Karla moved back on the bed and patted it. “Lay down beside me. We’ll find something to do until you ‘recover’, bro.””Looks like I owe you one.””Well, let’s see what you can do, then.”His mouth went to her nearest nipple. His hand slid down her belly to her pussy. He found that uncharted channel and played around the outer part.”They recommend that the hymen be broken with a finger rather than with the cock, it’s less painful and you won’t associate the first penis inside you with pain.”She looked at him and said, “David, my dear brother, take care of my cherry.”His finger probed inside her until he came to a blockage. He took a nipple in his teeth and bit down carefully. Karla gasp a bit and then he plunged through that line that marked the end of “girl” and the beginning of “women”.
