I had traveled there for Sam's 18th birthday barbeque. The weather at the time was hot, really hot and tonight I just couldn't sleep, so I switched the television on in my room and was watching some late night soft-porn.
Just when I was tempted to start touching myself, the door handle turned slowly. I froze, then rapidly moved my hands from under the sheet and put them behind my head, not noticing I'd left myself in an aroused state, which was noticeable through the thin material.
Sam entered the room. Sweet Jesus, I thought, what the hell is she doing up at 3am?. She put her finger to her lips as if to gesture a "shhh", then turned and closed the door behind her without a click.
She was wearing a pink nightie: thin straps at the shoulders with a tight-fit around the waist and thighs - not that it went that far down them anyway. It was pretty revealing but she clearly felt comfortable in my presence.
"What are you doing up at this hour?" I whispered to her, eager to get her out of my room as quickly as possible.
"I can't sleep ... it's too hot ... and I heard noises from down the hall." she confessed in a similar whisper, creeping towards my bed. At which point, I noticed the protrusion from under the sheet.
Oh fuck, I panicked, please don't notice, please don't notice! I thought to myself. She sat on the end of the bed and looked me in the eye, then turned to the television to see what I was watching.
"Hmmm, nice." She said dismissively, turning back to me and noticing my stiff cock making a tent of the sheet. She pretended not to notice but we both knew she had seen it. Sam flicked her dark brown hair away from her shoulder, then nervously began to whisper.
"Erm, yeah, okay, I was just wondering ...", she started, trying to break an awkward silence. She sighed, taking a deeper breath, and tried again.
"Jim." She said seriously. "I have a favour to ask of you".
"Sure, what is it, Sam?" I said, relieved that the conversation was NOT going to be about my hard-on.
"It's a bit unusual, Jim. You mustn't get cross when I ask you, and you must promise not to tell my parents."
Her parents were asleep in the bedroom at the other end of the hallway. I felt fairly sure that at this distance, our voices would not be heard.
"Okay Sam, I don't see why not", I said, "as long as you're not in any serious trouble."
"Oh no", she jumped in, "it's nothing like that, Jim."
"Fine then", I said. "What do you need?"
There was a pause. She took a deep breath and explained.
"It's my boyfriend. We've only been going out a while and I need ... "
"Some advice?" I interrupted.
"Not quite", she continued, "I need you to teach me how to give him a blow job."
My eyes widened and I felt my mouth open in disbelief. I had known Sam nearly her entire life. It didn't seem that long since she might have asked to sit on my lap, or for help with her homework, so this was a real eye-opener. She had grown-up quickly and I simply hadn't noticed. Before I could say anything, she carried on.
"I mean, I want you to LET me give you a blow job, but under your instruction, so that I can make it perfect for him when I need to."
"This doesn't sound like the little girl I used to know, Sam. I'm not sure that's a good idea", I told her, "I mean, you're only 18 tomorrow and ..."
She looked as if she were about to cry, as my rejection hit home.
"Oh come on, Sam, it's not as if I'm being unreasonable." I said. "I mean, I'm as old as your father!".
"Yes exactly", she said, fighting back the tears. "You are older and I can trust you to be serious about this. It's not like I'm asking some random guy. You've known me all my life and I know you wouldn't want me to be unhappy. AND I'm not a little girl anymore - I can make my own choices now." She said defiantly.
"That's true", I said, "It's just that what you're asking is not something we can turn back from once it's done", I said honestly. "You understand, don't you?".
She sobbed quietly.
This wasn't going well. Perhaps I could meet her half-way on this. "Think, Jim think", I said to myself. Then it came to me.
"Oh okay then Sam", I said, "I'll help you, but we're only going to ..."
"Yes! Thank-you!" She said, pulling back the sheet to reveal my naked manhood, her crocodile tears drying up all of a sudden.
Now, I was about to say to her, 'discuss it', but she took me by surprise and had her hand on my cock before I could say anything.
Things had gone too far already. I could see there was going to be little chance of changing her mind, and with her now groping at me, I decided to go along with it, just as she wanted. Besides, she had just overstepped the mark. I went on the offensive.
Looking her in the eye, I took control.
"Sam. We've known each other for a long time. You're about to cross a line here. Are you sure you want to?"
Sensing my authority, she simply nodded and, moving her hand away from my cock, awaited my first instruction.
Without a word, I swung my legs over the edge of the bed and told her to kneel in front of me. She obeyed. I grabbed the TV remote and switched it off, leaving only the moonlight, with us bathing in it.
Parting my lap, invitingly, I spoke. "Now Sam, take one hand and cup it under my balls."
She did it.
"Okay, and with the other, grip the base of my shaft gently."
With a solemn expression, she placed her right hand as I had instructed.
"Good", I said, "Good girl." Now start licking the end and, as you do so, gently move your right hand back and forth at the base, squeezing as you come forward and releasing as you move back."
Eager to get it right she started slowly, ever so gently; the soft skin of her hand lightly teasing me as her moist tongue licked at the tip.
Then she stopped and paused for a moment.
