Tease the underside with the tip of your tongue. There's a little fleck of skin on the underside, where the head meets the shaft, it's kinda like the male equivalent of the clit. Flick it every one in a while with your tongue and don't forget: the balls are your friends! Don't leave them out in the cold! Mix it up too, don't just suck and bob your head. Swirl your tongue in different patterns, suck in variety, and hum once in a while. Twisting your head and using your hand to fist what you can't take in then twisting at the same time is good too. But another important thing to remember is teasing. When you start out, don't just go straight to sucking cock. Rub and tease everything everything around the genitalia. Get close to touching the penis without actually touching it. Breath on the head once or twice and kiss and nibble the thighs close to the penis. Start out slow until he's frustrated and begging you to touch him THERE. Then go for it. Anticipation is a great thing.
I would be more than satisfied to just recieve oral sex without any vaginal sex taking place at all. Oral would be more arousing to recieve & to watch it being performed.
My favourite is when the woman holds my foreskin all the back and still with one, and with the other hand stroking my dick down the shaft while giving head. When I start to cum do this as fast as they can, then after start to go slow and release the foreskin, start to kiss the end of my dick, followed by sucking my balls untill im hard again. Then the games begin again
Like when she grabs it and taps it on her wet lips or tongue well looking in my eyes! Also love when she puts just the head in her mouth and works just below the tip with her tongue. Never hurts to lick from the bottom of the shaft up either.
