"You're bluffing I'll get it out and you'll just get a laugh at my expense," he wavered between standing and turning.
"OK," said Sally and pulled her shirt over her head, her skirt rustled to the ground, leaving her in her bra, knickers tights and shoes.
"Look Robbie, a girl with no tits!" Julie pulled her jumper off and unbuttoned her blouse. Pulling it over her head, her tiny boobs and hard nipples appeared and Robbie stared, torn between the large bra covered boobs of his Mum and Julie's tiny molehills. His cock was now fully erect but pushed tight against his jeans in a very painful trap.
"Come on son, let's see that lovely cock of yours," Sally said as she unhooked her bra, allowing it to fall onto the floor.
Meanwhile Julie unbuttoned her skirt and allowed it too to fall to the floor, standing in her panties and tights she smiled at Robbie and his predicament.
"Robbie, why not let it out and ease the pressure, those jeans can't be good for your circulation." Julie smiled at her brother.
Robbie's hands flew to his belt and unbuckled it, he pulled the button out and slid the zipper down. Kicking off his Rebok's he pulled his jeans and pants down then he tried to step out of them. Julie and Sally watched fascinated as his cock swayed from side to side and up and down as he tried to kick his jeans off. His cock was about six or seven inches long. Behind it was a thick nest of crinkly hair covering his groin and balls, which hung in a pouch under his cock. Finally freeing his feet he stood to face them, then pulled his t-shirt over his head.
"Bloody hell Robbie that's enormous, how the hell are we supposed to get that inside us?" Julie said watching his organ in fascination.
"Without putting you down dear, his cock is quite a normal size, and believe me when the time comes it will fit," said Sally wistfully.
"Aren't you two going to finish stripping then?" said Robbie urgently, eyeing his Mother and sister.
Sally and Julie stepped out of their shoes and pulled their tights and knickers off. Stepping out of them they glanced over at Robbie, whose eyes bulged out of his head.
"Wow, you're both beautiful, better than any of the girls in the films and magazines. Look at you two," and as he was looking hard at them a drip of pre-cum oozed out of his pee slit and formed a perfect tear on his cockhead. Julie looked intently and placed her hands on her hips.
"Right well, now we're all nude, why don't we take ourselves off to the lounge where it's warmer and more comfortable." Sally scooped her clothes up, giving Robbie a view of her arse and wandered into the lounge. Scooping their clothes up Robbie and Julie followed. Sally sat in her armchair, her clothes on a dining chair at the other end of the room. Julie and Robbie found a chair and placed their clothes on them, then wandered back to the sofa. sitting at opposite ends. Julie nearer to Sally.
"Ohh come on Robbie, sit by your sister, she doesn't bite, although if you ask here nicely I'm sure she will!" Sally mischievously winked.
Robbie shuffled along the sofa, apologising to Julie as his hand brushed her leg. Julie smiled and put her hand on Robbie's thigh. His cock seemed to swell slightly more and poke up towards his belly. Sally knelt down in front of Robbie, her breasts touching his knees. Robbie gasped and his cock almost took off on its own.
"Okay son, cool down, take it easy, ok? Now we'll just explore your body then you can explore ours ok?"
Robbie grinned and nodded, face crimson.
Julie tentatively moved her hand up Robbie's thigh to his groin. Robbie groaned and some more pre-cum oozed out the slit.
Sally leaned forward and gently took his cock in her hand, running her thumb through the pre-cum and spreading it round the head of his cock. Robbie groaned again.
"Mum, I'm going to explode I can't hold it back, sorry."
With that his cock slit began to emit a volcano of white gooey liquid, a few spurts flew up and it all ran down his cock onto his mothers hand.
"It's okay baby, that fine, that's right, let it out, relax." Sally coaxed as the liquid continued to ooze out his slit. He adjusted his bottom and opened his legs slightly, letting his balls sink between his legs pulling his cock down. Sally reached for a tissue and gently wiped his cock clean. Finding another she wiped her hands, tossing the crumpled tissues into the wastebin.
Julie watched in amazement and gripped Robbie's thigh in her excitement. Robbie winced and placed his hand over Julie's hand and loosened her grip a little, she mouthed "sorry" and grinned. Robbie ran his hand up hers to the crook of her elbow, then hesitantly onto her boob. Julie looked into his eyes and nodded, so he palmed her nipple and closed his hand over it.
"gently buster, I don't like it rough ok, most women don't, so go easy, yes that's nice, like that. mmmm." Julie stretched her chest up towards Robbie and felt for his cock. Wrapping her hand round it she murmured encouragement to him as he fondled her tiny breast.
"Ok Robbie, now try mine, notice the differences," Sally leaned in and took Robbies other hand and placed it over her breast, feeling him close gently on it.
"Good, that's nice; now use your hands and explore our breasts. Maybe if I sit next to Julie and you kneel in front of us." She suggested. They traded places and Robbie resumed his explorations.
He felt the weight of Sally's breasts and then returned to Julie. He watched as their nipples swelled and thickened and the pink skin around crinkled and puckered. Fascinated he brought his lips to Julies pert nipple and sucked on them gently, then transferred to Sally and repeated the action. Both women wriggled back in the sofa enjoying the feel of Robbie's hands and tongue.
"Robbie, that's really nice, I'm really enjoying you touching and sucking me, thank you."
"Me to Robbie, you're hands are so gentle and I'm getting really turned on, especially when you suck my nipples." Julie put her hand out and stroked Robbie's face.
Robbie smiled and bent forward again alternating between Sally and Julie, watching them begin to wriggle and clasp their legs together.
Julie suddenly arched forward and pulled Robbie onto her breast, before laying back with a sigh, Robbie looked at her in alarm. Sally pulled his head to her breasts and encouraged him to continue.
"You just made your big sister come, that's very good, now I'm just about ready tooooooooooooo," Sally exhaled and clasped her thighs tightly together, before easing Robbie off her breast. "Thank you Robbie, that was very nice, I haven't had such a satisfying orgasm in years,"
Robbie sank back on his heels and his cock was erect again. he then stood between the two women and smiled.
"That was brilliant, you're breasts are really neat, I love that, do all women want to do that?"
"Mmmmm, I do I love to have my breasts touched and stroked and my nipples sucked, but I've never managed to cum before just having them touched." Julie sat forward and looked at her brother's cock, "wow that didn't take long to recover did it."
Robbie looked at her proudly and grinned,
"considering how excited I am, it's no wonder I'm stiff again, That is the best moment of my life, thanks Mum, thanks Julie, I like this kind of learning."
They laughed and Sally moved to make room for Robbie, so he sat between them, raising his arms and putting them behind and then round their shoulders.
"Yes, like your Dad, you're very hands on!" Sally said with a grin.
They snuggled down and enjoyed just being close to each other, as his excitement passed Robbie's cock wilted then returned to its flaccid state. Julie looked in fascination and smiled at how it contracted and shrank back, almost disappearing into his pubic hair.
"Whoo look at that, a self retracting cock, do all boys have that?"
"yes when I'm not excited it's just a pee point, touch it see how soft and saggy it is." Robbie offered.
Julie gently put her finger on it and felt how soft and slippery it felt, she slipped her hand round it and twisted it slightly then back again. She felt it start to rise again and held it in her palm watching it stiffen. Finally it stood upright again and she circled it with her fist.
"Does it hurt, you know when it's stiff, is it painful?"
"No it's just stiff, it sort of sometimes gets half hard, which makes it difficult to pee, I can't pee when it's stiff either. In the morning I often wake up with a stiffy. The body does that if I need to pee but I'm asleep, that's good in some ways, but sometimes it takes ages to soften and I need to pee and that can be a bit painful, other than that, I love my cock."
"I would too, it's so sleek and big and soft and slippery. What do you think about to get hard?"
"anything and everything, You and Mum obviously, and lots of other women.."
"Me, why me, I'm your sister and I haven't got any tits, Mum at least has big norks, don't all men want women with big ones?"
"Julie you're well fit, and believe me after seeing these little beauties, I'll be hard in seconds and it'll last for days just thinking about them." Robbie smiled and pulled Julie closer.
"What about mine, do you like mine Robbie." Sally's eyes twinkled and she moved slightly making her boobs jiggle."
"Hell yes, they're fantastic, so different from Julie's, weighty, firm and with lovely large nipples, again that'll keep me up for days." Robbie smiled at Sally.
