Tina and her mother entered the house from the garage into the kitchen after a long morning of yard-selling. 19 year old Tina dropped her mother's bags onto the counter and rushed to the bathroom. She had to pee bad. Returning down the hall, she passed her twin brother's bedroom door, finding it cracked. The reflection in the mirror on the right side of the room stopped her in her tracks. Backing up a bit, she studied the reflection of her brother lying fully clothed on his bed jerking off.
Always looking for an opportunity to rib or embarrass her twin, Tina rushed to the kitchen to retrieve her mother. Putting her forefinger up to her lips to indicate quietness, she slowly led her mother to her brother's door, maneuvering her so she could look through the crack, whispering to her to look at the mirror.
Rita was startled and her hand went to her mouth to silence the gasp that almost escaped. The two women stood for a long minute watching the actions of John, hearing his soft moans and barely distinguishable words, but understood by his mother, she being closest to the crack and seeing his mouth form the words.
"Ahhh. Oh god. Fuck yes, mom. I'll fuck your pussy good."
"What is he saying?" Tina whispered.
"Come on, girl. Let him have his privacy." Rita demanded, tugging at her daughter's sleeve.
But Tina was not going to let such a moment pass. She skirted around her mother and barged through the door, "what's UP, bro?"
John was startled beyond belief, desperately trying to stuff his erection inside his pants. Failing that, he grabbed a pillow to put over his groin. He was embarrassed and red-faced. His eyes were darting between his sister and his mother. Considering what he was thinking as he was stroking his cock, nearing his climax, his focus mostly fell on her.
"Tina, come on now and leave your brother to himself. I'm sorry John but you know how your sister can be." Rita apologized.
"What! I was just reading National Geographic!" John offered.
"There must be some good-looking native gals in that magazine or were you just reading the articles?" Tina accused sarcastically.
"I don't know what the big deal is." John exclaimed. "Everybody does it. You know damn well you have?" He rationalized slinging dirt at his sister. "I've seen you!"
"He knows you well, Tina." Rita joined in the accusations. "You've spent a lot of time with your hands down your panties. Probably still do when Don is out of town! " She turned her attention towards her son. "Don't you have a girlfriend to attend to these things for you?"
John dropped his head even lower on his chest. He was ashamed that at his age he was so lacking in his "real world" physical knowledge of girls.
"Mom, I bet he hasn't even seen a naked pussy up close and personal." She said with conviction, knowing it was so as John had told her so, causing John to look scornfully at her.
Rita could not tolerate her daughter picking on her brother any longer. She sat down on the bed and placed her hand on his left thigh.
"John? Is that true? You have never seen a vagina other than in a magazine or on a video?" She asked with motherly concern in her tone.
"Yes." John replied sheepishly.
"My, my, my." Rita sighed, sitting silent for a brief moments in thought. "Then, I think that should change. I am sure that your sister here would be more than happy to accommodate you, wouldn't you Tina?"
"Like hell!" Tina gasped. "I work hard to keep the sneaky bugger from spying on me, seeing me naked."
In the back of Rita's mind was the words that she had heard her son utter in his lustful quest to ejaculate. She pondered if she should "feed the beast" by offering to show hers right off, but........
"Come on Tina." Rita coaxed her daughter. "I know you have a kinky mind when it comes to sex and you're no longer a virgin. That surprises you, John? It would be quite a lesson to teach her brother. Sooner or later a girl is going to let him close to her treasure. He should at least know what to do with it, don't you think. Now, be a good sport and get your panties off, and stop being such a bitch! John, you stand up and get naked from the waist down. Come on, now. It's all nature. Kike you said 'we all do it' and yes, even me."
Tina was not on who was raised to bark at her mother's demands. Her body language shouted defiance but she began to unbuckle the belt on her white shorts, putting them down over her still girlish ample hips, stepping out of them after they hit the floor. Then went her bikini style panties. Her belly was a bit pudgy, her ass beefy. Naked together, mother and daughter were pretty much alike, except Tina had a more lust bush, Rita a bit more weight.
"Tina, sit you ass on the edge of the bed." She assisted both to take position. "Now Tina, scoot back a tad and put your feet flat on the bed and spread those thighs for him. Be proud of that thing, girl! Look! John isn't embarrassed at all."
John was too curious to be embarrassed as he stood a few feet from his sister studying her pussy.
"Lift your shirt up a little bit, dear, and let John see your pretty little tits. Quite lovely and perky aren't they, John? Nice sized nipples. Hard too. That's a good indication, John. Despite your sister's rant, she's turned on by all this."
Rita, now sitting next to her daughter, pulled her daughter's right leg toward her, hugging it. She lightly probed two fingers through Tina's forested mound.
"Now, any man worth his salt likes a good thick forest of curly pubic hair. Her mound – don't be shy, push right here - is sufficiently meaty enough to act as a buffer for hard, rapid fucking. (chuckles) Grow up you two! You two are adults. Tina, as you can see has a robust labia, or pussy lips. It doesn't look like a female baby crack. Now, look here. When you take your fingers and spread the lips.......there it is. John, drop down on your knees. With your middle finger touch that little reddish button, right there.
