Turns out you can go on a whole roller-coaster ride in ten seconds. An emotional roller-coaster, that is. Bernice, my girlfriend, had just made the most delicious offer of my lifetime — one that made me instantly spring a stiffy — then she’d added an addendum that caused everything in me to freeze. I was stunned and confused, yet still turned on.

What she’d said was this: “Baby, I’ve got something to propose to you. I really want to have a threeway. Would you be interested?”

She saw the wild grin that stretched across my face and took it as an emphatic yes. But then she’d said: “Great! I already ran this by Mark, and he said he was into it.”

I knew Mark. Mark had dated Bernice some while back, and they were still friends. I was friends with Mark, too. He was a great guy. But he was...a guy.

Right then, I wanted to dial back the conversation to the first part of it: Bernice’s lovely proposal, which had caused such fantasy images to bloom immediately in my head. Two women and me in the mix. All of us naked and rolling around, kissing and groping. Their hands and mouths on my cock.

I tried to swap in Mark for the second fantasy woman, but it was a nonstarter for me.

Bernice was patiently waiting for me to say something. We were in her bed, having just screwed, and it had been terrific. I managed to say, “Let me talk to Mark first, OK? To make sure there won’t be weird feelings.”

My plan was to later claim I’d gone to Mark and decided the vibe didn’t feel right. Maybe I could let Bernice down easy.

She was amenable, and I brooded about the situation. A threeway was number one on my sexual to-do list, the ultimate ambition. I’d never had one. I imagined a good threesome was probably the best sex there was. That this lopsided version of one was being dangled in front of me — as it were — was incredibly frustrating.

I dutifully went to talk to Mark. We met at a quiet café. I stalled for a couple minutes, surreptitiously looking him over. He was undeniably handsome, with a great physique. But I wasn’t excited by him.

He leaned toward me, smiling sympathetically, and asked, “You having second thoughts about Bernice’s threeway idea?”

At that moment, I was very glad Mark was a friend. I let out a long breath and replied, “Yeah. I thought at first she wanted one with another woman.”

“Oh, she’s into that, too. But this time she must have her heart set on MMF.” When he saw my confused expression, he clarified: “Male, male, female.”

I hesitated, then asked, “You ever do, uh, MFF with Bernice?”

“Oh yeah. It was fantastic!”

I burned with envy, but Mark remained sympathetic.

“Look, there doesn’t have to be anything between us — at all. We can both just do Bernie, and she’ll dig that. I won’t touch your junk. But” — he leaned in again — “we’d both be naked in the same bed. So, you have to be OK with that.”

I really thought about it. Though Bernice’s fantasy wasn’t my chosen threeway, there was still something naughty and exciting about it. It felt adventurous.

“I’m in,” I said, finally getting into the spirit of things.

Bernice had all the logistics arranged. We met at her place. In her familiar bedroom, she had the right lighting and music. I was nervous, but she was ready for that. Wearing a silk negligee, she padded up to me and laid her soft lips on mine. My cock grew automatically hard as the kiss lingered. She always had that kind of effect on me.

Next, Bernice flitted over to Mark and kissed him, and my hard-on didn’t flag. After that, she tossed aside the negligee and spread herself out invitingly on the bed.

Mark started to strip first. I admit there was a certain peer pressure situation going on as I followed suit. But I didn’t feel awkward getting naked in front of him, even with my cock standing erect. His was, too, and I stared at his rod an extra beat or two — comparing sizes. We seemed about the same. I’d been in locker rooms but had never before seen another man’s hard dick in the flesh.

We got in on either side of Bernice. Mark put a hand on one of her breasts, and her chest heaved against his touch. Something like instinctive jealousy flashed through me but vanished so quickly it might have been a hiccup. I realized I was OK with my girlfriend being groped by another guy.

I felt up her other tit, finding her nipple as hard as glass. I tweaked it, and she moaned ecstatically. I loved seeing her turned on. Right then, I knew our ménage would be a success.

I rubbed my cock against her hip, and she reached for me. Her fingers closed around my shaft, and pleasure enveloped me. I kissed her, and our tongues tangled. She turned away, and I next saw Mark’s tongue wrestling with hers. Her other hand was wrapped around his cock.

I traced my fingertips over her slick pussy lips, and her hips bucked. I slid my fingers inside her passage, feeling her wet, enclosing heat. Suddenly, I wanted to taste her.

As I moved down the bed, I realized how smoothly all of this was flowing. There was a wordless understanding at play. Not only didn’t Mark touch me, but we also both shifted about in such a way that it didn’t actually seem like we were avoiding one another.

I settled between Bernice’s legs, and her satiny thighs rested on my shoulders. As I put my mouth to her pussy, I noticed Mark had straddled her chest. The clenching and releasing muscles of his ass cheeks — and my girlfriend’s sucking sounds — told me he was thrusting his cock into her mouth.

I was excited, and I ate her with more intensity. My tongue danced over her clit. I wanted to make her come while Mark was fucking her face. She soon gave a muffled squeal, and I felt her thighs quiver. I sat up, my lips wet and redolent with her orgasmic flavor.

By then, Mark had swung himself off Bernice. He was looking at me expectantly. So was Bernice. I surmised I was supposed to fuck her first. Mark’s spit-wet cock bobbed before him as I moved into place. My girlfriend’s eyes were blazing, and her face was flushed. Our liaison was living up to her expectations, I was sure.

I felt their two sets of eyes on me as I slid my cock into her. Far from making me nervous, being watched seriously turned me on. I sank myself all the way in, savoring the slick grasp of her — but I found myself looking toward Mark to make sure he saw everything. I was gratified to see his lips silently working, like he was encouraging me.

I stroked into her, falling into an urgent rhythm. The pleasure was intense. She rocked under me, with all her wonderfully familiar responses. Our flesh smacked together loudly. On impulse I brought my lips to hers and kissed her deeply, still plowing away. I thought I sensed the faint taste of Mark’s cock on her tongue.

Bernice’s ex crouched nearby as I fucked her. He was no more than a foot and a half away, in fact. I admired his veiny length. When I realized what I was doing and looked back at my girl, she was grinning. She gasped, and her pussy tightened around my pistoning rod. She took me with her into a mutual orgasmic reward. I went over the top, my cream jetting out as ecstasy suffused me. After half a dozen spurts I rolled off her, panting.

Mark took my place. There was no vestigial flash of jealousy this time. I lay languidly to one side and eagerly watched him slide his cock into my girlfriend’s pussy. I knew they were both aware of me because they’d look my way with bliss on their faces. Bernice’s eyes still shone excitedly, and Mark glanced repeatedly at my cock, which was helplessly stirring again.

He fucked her harder and faster. I started cheering them on: “Yeah, fuck her deep! Take him all the way!” They bucked and rocked crazily at that. Bernice let out a howl, and Mark’s handsome face clenched. I could tell he was unloading into her as she climaxed.

We lay sprawled on the bed, the air heavy with heat and our scents. I felt drowsy and aroused and wonderful. Bernice got up and announced, “I’ll be back.” I was about to explain to Mark that she liked to shower between sex rounds. But I realized I didn’t have to. He’d been with her already.

I looked at him. His eyes were halfway closed, and his cock lay hard on his thigh. He reached down and took hold of his own rod, wrapping his fingers around it. Then he said, “Go ahead. You do it, too.”

With that, I brought my hand to my vein-lined staff, which stiffened immediately. I was fondling my cock in front of another man, but that didn’t bother me at all. I noticed his shaft was streaked with remnants of Bernice’s pussy juice and his own come. But I also sensed the firm masculinity of him as he jerked himself.

He sighed with pleasure, and that made me happy. We slowly jerked ourselves off as the water ran in the shower. Mark and I were looking each other in the eye now, pumping harder. Neither of us heard the water stop. But when Bernice came back into the bedroom and spotted us, she said, “Don’t stop. That’s so fucking hot!”

Her presence was just what we needed. Seconds later, we each erupted, shooting out jets of jizz that splashed our hands and stomachs. But it wasn’t long before Bernice helped us rise to the occasion once again.
