Summary
     Sam had never gotten 'the talk'.
Notes
     Written for the blindfold_spn prompt: "dub-con - John teaches Sam
     about sex by presenting a spread out Dean."
Sam had never gotten 'the talk'.
His dad had never found the time or inclination to sit down and explain the
facts of life, and so he'd happily muddled by with a couple of overly clinical
biology lessons in school and some very useful tips from his sixteen-year-old
brother on what to do with a girl.
Both sets of advice had fallen short when Sam had hit fourteen. Entirely to his
surprise, his dick had become an equal-opportunist, showing interest in hot
guys as well as hot girls, and, like the astute boy that he was, Sam had
realized there was a gap in his education.
The matter was never addressed in his biology classes and he hadn't wanted to
risk the embarrassment of asking his big brother so he'd resorted to the final
option: asking Dad.
John had choked on his beer when Sam brought up it and so he'd assumed that was
the end of the matter. Therefore, when John called him into the bedroom two
days later, Sam was more than stunned that John was going to help him out,
practical lesson included.
He edged round the door, eyes wide and unbelieving as he asked quietly, "Dad?"
John smiled benevolently up at him, patting the mattress. "Come sit down,
Sammy. We've got some training to do."
Gingerly, Sam sank to a seat and watched in amazement as John ran a soothing
hand up and down Dean's bare thigh.
His older brother was kneeling on the bed, stripped naked and bent forward so
that his hands were on the headboard and his ass was raised in the air. His
skin looked pale in the dim light of the bedroom, and Sam noticed his knuckles
turning white under the force of his grip as John strokes between his spread
thighs.
Voice low and confident, John began to speak, "Okay, Sammy, the first thing you
need to know, is lube. This little hole-" He brushed Dean's hole in
demonstration. "-is very tight, even for someone like Dean, and before you get
anything up there, you need to make sure it'll fit."
Digging out a jar of Vaseline, John coated two fingers, slapping them against
Dean's hole with a wet slop before easing one inside. Sam watched his brother
shiver at the cold touch but listened with interest as his dad continued,
"Different people can take different amounts, especially after a lot of
stretching. Hell, I can fit my whole fist up there if I prep him well enough,
can't I, Dean?"
Dean's "Yes, Sir" was subdued, but Sam was entranced at the thought of his
whole fist fitting between his brother's cheeks. His cock stiffened a little
more at the prospect and he saw John smile when he noticed.
"You've got a pretty brother here, Sammy. Lots of people would be interested in
him, so when you get older, it's gonna be your job to take care of him like I
do now."
Sam nodded eagerly. "Yes, Sir."
Three of John's large fingers were now working inside Dean's ass, and Sam
watched, fascinated by how Dean's stretched hole could possibly take more.
"Does it hurt?"
John looked surprised by the question but shrugged, continuing the slow
thrusts. "A little at first, I guess. He's used to it now though, right,
Deano?"
Dean nodded, his head dropping down out of Sam's sight as he stifled a groan.
Sam frowned at the noise and John explained, "That's because I hit his
prostate. There's a little gland inside men's asses that feels real good when
you stroke it. Hit that regularly, and Dean'll be moaning under you like a
bitch in heat." He withdrew his fingers, gesturing to Sam. "You try."
Uncertainly, Sam inched forward, coating his fingers with Vaseline before
slipping them cautiously into Dean's ass. His eyes widened at the feel of tight
muscles gripping his fingers and he worked them slowly, hearing Dean whimper as
he brushed against the spot his father had mentioned.
He added another finger and his dick hardened further in sympathy as he ached
to feel that tightness around his length rather than his hand.
Always aware, John read his thoughts and patted him on the shoulder. "You wanna
give it a try, son? He should be opened up enough by now."
Sam nodded eagerly, almost falling over himself in an effort to strip his pants
off. As he did so, John advised calmly, leaning back on the bed, "Now, Sammy,
it doesn't matter so much with Dean as he's your brother, but if you do this
with anyone else, it's best to wear a rubber."
Sam nodded again, kneeling between his brother's legs as he wondered why he'd
ever want to do this with anyone else when he had Dean here already, spread,
slicked and trembling with what Sam assumed was want.
"Alright, Sammy. You want to ease in slowly and once he's adjusted to it and
you're happy with the tightness, you can push in the rest of the way. Don't
worry too much about Dean; he can take it."
Absorbing his father's words, Sam gripped Dean's hips with clammy hands and
nudged the head of his cock past the ring of muscle. He groaned at the
sensation, gasping as Dean tightened around him, and pushed in further, loving
the sensations shooting through his body. With a deep breath, he drove the rest
of the way in, feeling Dean whimper beneath him as he moaned in ecstasy.
"How's it feel, son?"
"Amazing," Sam stammered in disbelief. "It's so tight, I..."
"Good." John smiled indulgently. "Now, nice slow thrusts until you find your
rhythm. It's just like Dean's your own hand; you go at the speed that feel
right."
Biting his lip, Sam nodded once more, not sure how long he was going to be able
to last under this new and intense pressure. He started slow, feeling the
mattress and Dean shift underneath him, but soon picked up speed, youthful
stamina bringing him quickly to the edge.
His balls slapped against Dean's ass, and Sam closed his eyes, savoring the
feel of the slick, tight channel gripping his cock like a vise as he fucked in
and out, gasping with pleasure. Head falling back, he came with a cry, dick
pumping into Dean's reddened hole as Sam shook with his orgasm.
He struggled for breath as he came down from the high and pulled slowly out of
Dean's ass, looking down at his brother in curiosity and seeing his own come
start to leak out down Dean's trembling thighs. Dazed and smiling, Sam looked
over at John who beamed at him proudly.
"Good job, son." His hand shepherded him off the bed as he instructed, "Now,
you go get cleaned up."
Clutching his clothes, Sam backed off, glancing over at the boy on the bed,
"What about Dean, Dad? Should I-"
"No," John interrupted cheerfully. "He's a big boy now. He can clean up after
himself." Sam found himself guided to the door as John added jovially, "Now, go
clean up. I need some time alone with your brother."
