Around 7 years ago, when I was first dating my now wife (we'll call her Sonia), I'd gone on a few dates with another girl (let's call her Lily) at the same time but then as Sonia and I got a bit more serious I told Lily that I just wanted to hang out as friends if she was ok with that. She vocalised that she was bummed out but understood. Anyway fast forward 2 months in and Sonia and I still haven't had the "are we exclusive" talk, but we also haven't had the "I'm seeing other people" talk either. I'm having great sex with Sonia but Lily and I have amazing chemistry too, and the sexual tension is veritable in every interaction: every hug hello, kiss goodbye and shared grins at conversational sexual innuendo.

One night I'm hanging out at Lily's, and I'm helping her pack for a little holiday. Keep messing around with her panties and bras, flirting and chatting and we almost kiss several times but neither does anything. I'm going crazy in my head, and the other one is equally flushed. I say it's late and I should go (it's just after 1am) so I head home to clear my head (take that as you will).

Eventually I'm in bed, still horny and I send her a text "I really wanted to kiss you. Fuck!"

She replies within seconds "Wtf I wanted to kiss you too! So fucking much! But I thought you just wanted to be friends!? Wtf! Come back right now, or I'm coming to yours."

My housemates are in and her house is empty, so I tell her I'll come over (she lives a 5 min walk away).

I'm walking back to her house at almost 2am, and I'm tingling all over. I can imagine (and later have it confirmed) that she is feeling the same. I'm thinking wtf am I doing, but knowing how much I want to feel her body up against mine, I rock up to her semi detached and notice the bedroom of one of her housemates, Jackson (who also knows Sonia and has previously questioned Lily and I about our flirting when I'm seeing Sonia). Not wanting him to know about this, I message her "Downstairs." She comes to the front door with a huge smile on her face and the most irresistible, lip bite, but closes the door behind her and whispers "Jackson came back from his girlfriend's!" Before I can respond, she has pounced on me. Our lips, tongues, fingers and arms are in a passionate, urgent tangle, sliding gliding and gripping.

I pin her against her door and for what feels like ages, we are just wrapped up like this, rubbing each other through clothing, breathing deep and heavy, suppressing moans and sighed drools of "fuck" and "ughhh". Suddenly she pulls away, takes my hand and leads me inside. We get in her room, and gently close the door. I spin her around, pin her against her bedroom wall. I start kissing and licking her neck while my hands run down her body and one by one remove her clothes until she's completely naked. I tease her with my fingers grazing her hips, ribs, and sideboob. I take my mouth down and up her body before turning her around and then she reciprocates, until we are skin on skin, ecstatic, and with darkness and silence blanketing us in an illicit, thrilling secrecy. I pick her up and without thinking l, throw her on the bed - fits of suppressed giggles and silent shushing I crawl over her body, kissing licking and biting, then whilst lips and tongues are again meeting in wet knots, I pin her wrists above her head and take my tongue on a tour of her neck, collarbone, down between her breasts, circling nipples then sucking her belly and licking her belly button until I'm where my salivary glands want me. Long slow licks, light quick flicks and every other delectable movement I'm doing gets me as hard as she is wet. I lick and suck her for a little age and stop before she finishes. "Not yet."

We get to it. Legs draped over my shoulders I start sliding around the outside, up and down, teasing. It's killing me as much as her, and I finally push inside her, slow and shallow to start, then hard and fast.

We use her room, we get into several positions and variations, and then what feels like 20 minutes later but turns out to be just under an hour (and 3 orgasms for her) after we got in her room, she's sucking and licking me, unloading me on her tongue, neck and chest.

We collapse in bed wrapped up in each other, both whispering "what the fuuuucckkk". She tells me I am welcome to stay or head home, she understands either way. We spoon, she falls asleep, and just as I'm drifting off, I realize I'm meant to meet Sonia in a few hours for breakfast at a cafe before... church...

I slip out and walk home with her smell in my beard, her cream and my cum still all over my cock, and a feeling of full satisfaction with a tinge of guilt, smiling in the faint light of day.

We never did anything again, Sonia and I had the talks and got serious within a week, and Lily met another guy soon after as well. Sonia never found out the extent or timeline of what happened, but I had told her that "early on" Lily and I had kissed. She still doesn't know...

One day about 6 months later Lily had a few drinks and were reminiscing, laughing about it to mask how much we wanted to repeat it. We kissed, and let each others hands wander a bit but stopped and left it there.

On evening walks even now, whenever I see a semi detached house with the top left light on, I have a little flashback to that doorstep and that bedroom.
