My first view of a woman's nipples was a picture of an African tribeswoman in National Geographic. She had enormous nipples and areola and I was obsessed from that day.
My wife is an extremely attractive, mature brunette, with a classy bobbed haircut and a petite hour-glass figure -35' bust (32DD bra size), 26' waist and 38' hips (with a wonderful rounded bottom). She has a luxuriant hairy bush (trimmed only in extreme beach weather - not very often in eastern England) and a beautiful pussy, vaulted like a Gothic cathedral. But for me, the piece de resistance of her charms are her nipples. Her areolae are some 2 1/2 inches across and delightfully 'bumpy', surmounted by deep pink, 1/2 inch diameter thimble-sized nipples.
I encourage her to wear button-up tops or dresses to tantalize me during the day and prolong the anticipation of undoing her to get to those succulent nipples. And I like her to wear lacy low-cut bras which display her plump breasts to maximum effect, with her large areolae protruding provocatively above the lace.
When I suck, lick and gnaw her nipples she squirms with pleasure, but very soon re-directs my fingers and tongue to her eager clitoris. This is rewarded as she cums violently and noisily, bucking and thrashing the bed. I sometimes cum myself just at the sight and sound of this, even though she may not have even touched me yet. She always needs to recover her composure after this exertion and so I must wait a little longer for my relief. So we embrace in each others arms for a while and when she has recovered she starts to play with me, squeezing my testicles, and twisting, bending and tugging my penis to full arousal. Then the serious masturbation begins, with varying speed, pressure and intensity-stroking, rubbing and flicking my shaft, cap and frenulum (my 'seam' as she calls it, which by this time feels tight and sharp enough to snap). I take as much as I can of this exquisite treatment and then ask her to stop, so as to prolong the pleasure, although I'm bursting to cum.
After my wife has orgasmed her nipples are like bullets, so I gently suckle on them again. Then when I really can't wait any longer I beg her to finish me off. Whilst I am just 6 1/2 inches in length and 5 inches in girth, I do have a good-sized and very sensitive circumsized cap, which bulges like a purple plum in response to her touch. So she encircles my shaft with her forefinger and thumb, just below the cap, rhythmically pulling against it and occasionally drifting her fingers over the ridge to tease and delight cap and seam, taking my breath away. If I'm really lucky her final strokes will be with those rock-hard nipples and I'll squirt agonisingly over them. Is there a more erotic sight than your lover's nipples dripping with your cum? She might then request that I suck the sticky cream off - how could I refuse? Oh, my Darling how I adore your delicious nipples!
