Think about this. You're on top of my wife. Your hard cock is moving slowly in and out of her slippery, soaking wet cunt. Your cockhead might be going straight in, but you flex it upwards. So it presses against her innermost & upper part of her of her hungry pussy on the way out. The both of you have developed a slow, steady, and hot rhythm. You both work together as one, like the two of you were a camshaft.
She has one hand behind your neck, her nails lightly messaging your head while she kisses and gently sucks the ear lobe while her nose exhales hot breath on the side of your head. Her right hand roams from your lower back the very crack of your ass cheeks. She has legs spread wide, one foot caresses your calf, and the other guides your camshaft motion with her heel pressing into your as cheek.
Your lips aren't idle either. You've been sucking her nipple for while now, gradually increasing the pressure until it was hard and stiff. Sometimes your teeth graze against it, bringing a soft whimper of pain & pleasure from her throat. Most of your weight is on your left elbow, your hand supporting her upper back. The other has been caressing her soft and pliable buttocks. You're are pressing, pushing and probing your middle finger against her tight rectal lips. She's been resisting that digit's advances up till now. But too many things are happening all at once. Too many nice things. Too many pleasures. She would never consider letting her husband touch there. But here she was relaxing those very puckered muscles. Opening, and closing a little more each time. Allowing your finger to enter a little deeper each time. A little more pleasure each time. And then another little involuntary moan of pain & pleasure.
Your cock is barely retracting now. The big swollen head is doing all its work deep inside her pussy. There's no reason to go in and out anymore. Your cock and her erroneous zone were undulating in perfect unison, in just a few inches of working space. The muscles in that zone were beginning to contract and relax around your cock.
You stop sucking her nipple only to slowly move your tongue from her taunt areola up her breast to the neck, then over her chin to her wet waiting lips. She accepts the tongue into her hot mouth, while she engulfs your lips with her own. She sucks it deep. The way she would if it was a cock. Now all her holes are filled. And she loves it.
The contracting muscles around your cock are increasing in pressure. She's breathing harder now, as she sucks hard on your stabbing tongue. Slobbering all over your lips. Her asshole is gratefully accepting your middle finger now. The rectal muscles clamping down on the digit, sucking it as if she was stopping it from escaping. She's wondering what it would be like to have a cock up her ass. Your cock up her ass. But too many things going on in her mind. She's close!
Her virginal walls are now sucking your member like a vacuum. She's close, and so are you. Your balls were riding up and down her ass crack. But now they're tight and hard. They're coiled to release your hot sperm. Your rock hard cock is getting a little longer, a little thicker, and the purple head a little bigger. You're ready, but you're going to wait for her. You know it won't be long.
