Robyn Puritan watched through the steam covered door of the shower as Richard, her 18 year old fraternal twin lathered up his 6'1" 220 body after football practice. Their parents, Wellington and Victoria tried to instill in their offspring culture and proper etiquette which didn't include something as common and savage as football, but that didn't stop Richard from becoming an All-State linebacker his senior year of high school.
Robyn's hair was still in the pony tail she wore during cheerleading practice, and she slipped the crop top of her uniform over her head as she studied her brother's muscular frame and large dangling penis.
Dropping her skirt and panties to the floor, she surveyed her body in the full length mirror on the back of the door. Though not as tall as her twin, at 5'9", her 138 pounds were totally fit with strong tapering thighs and nicely bulging calves. She thought her bubble butt was her best feature, though most of her male classmates couldn't take their eyes off her 38 C breasts. She smiled, knowing she was the complete package.
She slowly opened the shower door, which had become a routine whenever their parents were at one of their Board meetings, or jetting around the globe to support the latest politically correct charitable function.
She was greeted with a smile from her brother as he moved to take her in his arms and taste her moist smooth lips. He loved the way the Puritan competitiveness took over as their tongues wrestled for supremacy.
Robyn let one soapy hand travel over Richard's bulging arm muscles, moving to his broad shoulders and well developed pecs and took his soft cock in her other hand. She loved the way Richard's hands explored her breasts and drew her into his warm hard body as he stroked and caressed her round firm ass.
Both twins broke the kiss, breathless, as their hands continued to explore one another's body.
Richard smiled and said "God you are an incredible kisser. You do realize dear Mother and Father would kill both of us if they ever found out we shower together."
Robyn slowly stroked his large cock until it was standing at full attention and with her other hand she soaped up his dangling ball sack, causing him to separate his legs further and give her complete access.
"Well I'm not going to tell them, and having kept our shower secret for three years now, I think we been pretty successful in our little secret.... Which brings me to a question... Have you ever thought of going further?"
"What do you mean Sis?"
"I just mean, I know your girlfriend Samantha, and my wonderful love, Roger are as prudish and uptight as our loving parents, so I sometimes get horny as hell and would like to experiment a little."
"I don't know Sis. I mean showering together is one thing, but don't know if we should take it any further."
"You sound like Mother and Father. Come on, we're 18 year old virgins for God's sake. Let's be a little daring."
"Well, OK I will give it a try."
Robyn bent over to cut off the water then opened the shower door and grabbed them each a towel.
"Great. I need to pee, and then we can go into my bedroom and try a few things."
Robyn set down on the toilet and started a steady stream of urine as she casually dried herself, with Richard looking on in amazement.
