If you’re lucky, you’ve got a good friend or reliable ex-lover you can go to for sex troubles. Karen was both of those for me.

I went over to her place, she poured wine, and I told her what was wrong. I was seeing a guy named Vincent, and I was serious about him. The problem was, I was an oral sex neophyte when it came to men.

As a bi woman I’d mostly had long-term relationships with other women. The guys I’d fucked had mostly been one night stands. Somehow I’d never acquired a cocksucking talent, and men who were going to be gone the next morning never pressed me about it.

“Vincent and I have slept together twice now,” I said. “He’s great in bed. He went down on me both times. I was afraid to reciprocate. I mean, I just don’t have that skill set in my sexual toolbox!”

Karen leered. “Does he give good head?”

“Great. But could we focus on my predicament?” I took a big swallow of wine.

Karen too was bi, with more experience with men than I had. We’d had a good relationship, and I was glad we’d stayed friends. She thought for a minute, then got up and held out her hand to me. I followed her into her familiar bedroom.

When she moved toward her sex toy drawer, I said, “I didn’t come over for a nostalgia fuck, Karen.”

She didn’t bat an eye. “I’m not offering one. But this requires a very physical demonstration. I can’t just talk you through it.” She fished in the drawer and came up with two strap-on dildos. “Which size is Vincent?”

I pointed to the bigger one. “Lucky you,” she said and peeled off her top, exposing her lush tits. Helpless desire stirred in me. She took off her jeans but left on her panties. Then she buckled on the fake cock. I thought of all the times she’d fucked me with that rig, then pushed the thoughts away. I too had to focus.

“You want to stay dressed like that?” she asked. “This is going to be physical work. You might want to strip.”

I hesitated but then did as she’d done, undressing down to my panties.

“Okay,” Karen said, getting on her bed, “let blowjob practice commence.”

She spread her legs, and the plastic pliable cock stood straight up. I lay down between those legs. She told me to get comfortable, use my elbows for support. I settled in. My head hovered just above the fake cock. It really was Vincent’s size. I felt intimidated.

“So,” Karen said, “there are some nice easy preliminaries you can do before you get down to anything drastic. First, just take him in your hand, squeeze him — gently, but let him know you mean it.”

I reached out and did so. The dildo was cleverly designed to have an almost flesh-like texture.

“Vincent’ll probably be watching you, so you can create anticipation by gazing rapturously at his cock. Make him think it’s the best one you’ve ever seen.”

I imagined him lying before me and felt lust heating my face.

“That’s good,” Karen said. “Now just lean forward and breathe on it.”

I sighed my hot breath on the cock, knowing how good that felt on my pussy.

“Now lick him up one side just using the tip of your tongue. Great. Do the other side. Yeah, slow like that. Savor it. Get him really worked up.”

When I looked up, I saw Karen watching me with glittery eyes. She said, “Yes, look up at him now and then. Most guys like that. Now, give the cockhead a swirly lick.”

I ran my tongue over the dildo’s bulbed head. Karen said to seal my lips around it. I did that too. Now it was just a matter of sliding my mouth down the shaft. I would feel him twitching, I was told. I should keep my tongue moving. Flatten my cheeks in around him and actually suck — it would create a nice firm suction.

I knew we were getting close to my gag reflex. Karen assured me she would get me through it. But I was also aware that she seemed turned on by all this, like maybe I was actually sucking her cock.

Also I realized I was more than a little excited here. My panties were damp.

But we stuck to the lesson. I managed not to choke, and after several tries I overcame my gagging reflex and actually took that fake cock into my throat.

When Karen was satisfied that I was up to speed, she reluctantly ended the demonstration.

“When he comes,” she said, “you can either drink his jizz or not. That’s up to you.” She grinned wickedly. “Personally I think the stuff tastes like nectar.”

It had been a weirdly intimate interlude with Karen, but I was immensely grateful for her help. I decided to waste no time, and arranged to see Vincent that same night.

He was a ferociously handsome man, with fine muscles. More than that, he was smart and kind, the sort of person I could see spending a lot of time with.

He came over to my place. We kissed by way of greeting, and familiar excitement coursed through me. I could feel him already stirring.

But he pulled back, tilting his head quizzically. “Hey, are you nervous about something?”

I liked that sensitivity in him. Most men I’d known wouldn’t have paused if there was the possibility of sex. I realized then that I felt a little guilty about having gone to Karen that afternoon. We hadn’t had sex exactly, but that had certainly been a kind of sexualized scene.

I decided to come clean. I told Vincent about it, which meant I had to tell him why I’d gone to Karen in the first place.

He listened attentively. He already knew I was bi, so there was no shock there. Finally he said, “Wow. You did all that just for me? I’m...touched. You’re quite a woman, Trixie.”

We kissed again, deeper this time. Our tongues caressed. I pressed my mouth hard on his. I felt him swelling in his jeans. I knew I’d picked the right guy to get serious about.

I took his hand and led him into my bedroom. My flesh tingled. I felt a nervous anticipation, as well as rising excitement.

I took off my clothes. Vincent stripped too, and I looked his fine naked body up and down. His cock stood straight out, a hard bar, the cockhead swollen and purplish. He really was the size of the dildo I’d sucked earlier today.

There was of course no mistaking what sex act I was going to undertake here. Wordlessly he got onto the bed, lying back, muscled legs open.

I crawled up after him, laying down on my belly between those strong thighs. My face was just above his rampant cock. For two panicky seconds everything Karen had told me vanished from my head, then it all snapped back into place. I let myself grin. I was ready.

I took him in my hand, fingers curling around his impressive girth. I felt the heat of him, something Karen’s dildo wasn’t able to simulate. My hand tightened on him and his body shifted on the bed. A low sigh slipped past his lips.

Improvising a little, I gave him a few slow pumps. He throbbed in my grip. As I did it, I was gazing lustfully at his staff. It was something else Karen had told me to do, but I wasn’t faking it. I was entranced by the beauty of his cock.

I leaned down a few inches and breathed hotly on him. He grunted with pleasure. With my tongue tip I licked him up one side, then the other. He groaned.

I moved my hand to his balls and gently cradled him. Sexual instincts seemed to be taking me over, but I had Karen to thank for the ground work.

More confidently now, I gave his thick cockhead a swirl with my tongue. The texture was so smooth. His muscles jerked at the contact. A bead of thin precum oozed from his piss-slit, and my tongue lapped it up. The salty taste was intense. I still didn’t know if I was going to drink his load or not. I figured I would decide in the moment.

After a long lollipop-swirl on his cock’s crown, I closed my lips around him. At that point I lifted my eyes to Vincent’s face. Sure enough, he was watching me with rapt intensity. His eyes blazed. He was seeing me with his knob in my mouth, lips made into a cocksucking circle.

He twitched in my mouth. A thrill of triumph went through me. My pussy was streaming and my nipples were hard and tight. I started to suck my way down his shaft. My tongue stayed busy. I felt the individual veins squiggling his rod. His flavor filled my mouth, manly and musky. His balls stirred in my gentle grasp.

I concentrated. I made sure not to break the seal of my lips. I applied suction. My cheeks closed in around him, and he let out a growl of pleasure. I must be doing good so far!

But I was leery about my gag reflex. I tried to remember exactly how it had felt this afternoon. What if I couldn’t do it again? What if my throat muscles refused to cooperate?

But this was about more than just mechanics, I told myself. I really liked this man. I wanted to please him, to pleasure him with my mouth.

Keeping that in mind, I sucked him down further, swallowing inch after inch. Finally I took his cockhead into my throat and sucked him to his base. I had all of him. I wanted to cheer, but could only make a rumbling sound.

Vincent cried out, “Oh! Humjob me. That’s so fucking good!”

From there on I knew I could do it. I lifted and dropped my head. I sucked him hard. I growled deep in my throat, and he really liked that.

The motions put me into a kind of carnal trance. Up, down. Neck straining deliciously. Sucking him down to his balls every time. When I looked up at his face again, it was twisted in mounting ecstasy. I picked up my tempo, head flashing up and down.

His thighs tightened around my shoulders, and I realized he was seconds from coming. I could pull my mouth away and finish him with my hand. But no. I wanted my first-ever blowjob to end in total victory.

When he howled and started unloading, I swallowed every hot spew of him. Karen hadn’t lied. He tasted like nectar.
