Calvin was sprawled out on the couch wearing only his tight red shorts as his sister Terry answered the front door. He had a hard-on from hell or rather from his sister sucking on his dick as they waited for Debbie to arrive. It had been two weeks since their weekend of lust and this was the first time they had the house to themselves.
It had been a long two weeks as Terry teased and flashed him every chance she got, which was constantly. Their mother had almost caught her on a couple of occasions but that seemed to just spur her on. Before their parents left, she would grab his dick through his regular shorts every time she got close to him.
They had stood by the front window and waved goodbye. As the car turned the corner at the end of the street, Calvin grabbed his sister around her chest with his left arm and held her tightly as his right hand found its way under her short skirt. She didn't have panties on and his fingers found her clit quickly.
He held her right in front of the window as he rolled her clit around firmly. She had gasped and struggled for a minute before she groaned loudly and shifted a foot to the side. Then her hips were moving back and forth, pressing her clit tighter to his fingers one second and reducing the friction to a light caress the next.
In a few minutes she was coming long and hard, her hips jerking to a rhythm of their own. Her head was back against his chest rolling from side to side. He had ended up half carrying her to the couch. As she caught her breath, she had sighed and then giggled. "I needed that so bad."
"So bad are the words for you. If I thought I could have gotten away with it with mom and dad here, I would have spanked your little butt."
"With your hips or your hand?"
Calvin had chuckled. "Both probably."
Terry had sat up and turned to go to her knees. Her hands found his dick and rubbed it through his shorts. "We have two whole days."
"And?"
Terry giggled. "How about if I invite Debbie over?"
"And?" Calvin asked again.
"I keep thinking about the three of us in a pile on my bed," Terry whispered softly.
"Call her, I'm game, if she is."
Terry groaned softly. "That's just it. I don't know... uh... what she would be up for."
"There's only one way to find out," Calvin replied with a grin. "You said she had a big crush on me. My little red shorts and a full hard-on should get the ball rolling."
Terri squeezed his dick. It was as hard as steel. "Hand me the phone."
One phone call, a change of shorts for Calvin, and a slow blowjob later, Terry opened the door and greeted Debbie with a big hug. She still had on her short skirt but now she had it pulled up even shorter, the waistband rolled three times and had a short blouse on with four buttons undone. There was skin showing down between her breasts.
When they broke the hug, Debbie was grinning as she came inside. Her eyes flicked up and down from the hem of the short skirt to the skin showing at the top. "Love the outfit," she whispered and then looked down at her t-shirt and jeans. "I seem to be over dressed."
"Then take it all off," Calvin said from the couch.
Debbie wheeled around. She hadn't noticed Terry's brother until he spoke. Her eyes took in his bare muscular chest and then the long thick ridge in the front of his tight shorts. Her eyes grew wide and her mouth worked but no words came out.
"I think the cat has her tongue," Calvin said with a big grin.
Debbie licked her lips and nodded. "Uh, yeah," she whispered and then swallowed hard. "I... I... I..." she stammered a moment later.
Terry grinned at her brother and stepped behind Debbie. She reached around and hugged her girl friend, her hands under each breast. Debbie squirmed and then gasped as Terry kissed her on the neck.
"I... I... I..." she stammered and then gasped even louder as Terry's hands moved up to caress and squeeze her breasts. Debbie's hands jumped up to cover Terry's as she stammered again.
"Girl, you need some new material," Calvin said with a chuckle as his right hand moved over to rub lightly over his hard dick under his shorts.
Debbie's eyes followed his hand and then slowly closed as Terry squeezed and massaged her breasts and kissed and licked her neck. She moaned softly and moved her hands back down by her sides, surrendering to the pleasure Terry was giving her.
Calvin was off the couch and on his knees in front of Debbie. He licked and kissed her belly as his fingers worked the snap and zipper on her jeans. Debbie moaned even louder than before. Calvin's hands inside the back of her loose fitting jeans made her gasp. His lips and tongue on the upper edge of her smoothly shaven mound made her hips jerk and twitch. The jeans slowly moved lower off her hips.
Terry continued to kiss her best friend's neck as her right hand moved down and under her t-shirt. Debbie wasn't wearing a bra so now she had one hand on a cloth covered breast and one on bare skin. The bare breast felt even warmer and softer than it had through the shirt. She moved her left hand down and then up. Now she had a bare breast in each hand.
Debbie was getting close to overload. Hands caressing and squeezing her breasts and lips on her neck were one thing but Calvin's hot slippery tongue on her mound was something else. She kept flexing and wiggling her hips trying to make him go lower but he stayed where he was. He had room as she felt her jeans down around her knees. She tried to spread her feet wider apart but the jeans limited her.
Suddenly, Calvin's tongue brushed across her clit and Debbie thrust her hips forward and yelled incoherently as he licked her mound again. "My clit! My clit!" she yelled loudly.
Terry's soft giggle next to her ear was lost as Calvin's tongue zeroed in on her clit and lashed it up and down and back and forth. After all of her fantasies about Calvin, him actually licking her clit shot her into orbit. The fact was so much better than the fantasy. Then he was sucking on her clit and flicking it wildly. She went even higher.

Debbie sighed deeply and smiled. Her eyes were closed and she was floating on a fuzzy cloud of endorphins that felt wonderful. A tongue flicked at her left nipple and she shivered. A tongue flicked her right nipple and she whimpered. She briefly wondered where her t-shirt was and then it dawned on her she was laying on her back. Her eyes snapped open. Terry was lying on one side of her and Calvin was on the other.
They were lying on their sides and had their heads propped up on their hands. Terry leaned in and licked her left nipple and then Calvin did the same to her right. Debbie whimpered and then moaned as the tongues touched her skin. Then there was a mouth on each nipple, sucking as a tongue flicked and swirled around each of the hard buds. She groaned loudly as her eyes closed.
Terry lifted her head and the nipple in her mouth stretched and then snapped loose from the suction she held on it. Debbie made a soft gasping sound and then made it again as Calvin treated her other nipple the same way. "The floor is fun but my bed is more comfortable," Terry whispered softly to her brother.
Calvin chuckled. "Yeah but I think I'll have to carry Debbie upstairs."
"Give... me... a minute... to catch... my breath," Debbie said slowly.
