My wife and I do this so often, it could almost be classified as a Technique, but I'll keep it in this section and give a recent example.
Our sex life is still great after 12 years of marriage. We don't have traditional intercourse that much, however, because at the end of a long day, it's hard to muster up the energy. Still, the wife knows I need relief.
She takes a shower right before bed and joins me (I'm usually watching TV or reading). I'm lying on my back. Wearing only her panties, she'll get on her hands and knees next to me and begin to kiss me and lick my nipples. While she does this, I begin stroking my rock hard cock. She then leans forward and presses one of her nipples into my mouth. I lick and suck one and then the other. She's now making noises, like quiet little moans, and she begins rocking her body back and forth with her ass still high in the air. She is pretending she is getting fucked from behind while I suck her nipples and kiss her mouth.
She goes back to work on my nipples, still rocking back and forth, her breathing now getting heavier. I'm still stroking away, getting ever closer. She tells me to close my eyes, then she licks one finger and uses it to 'lick' my other nipple while she continues to moan and work on nipple 1. It feels like I have two girls working my nipples at the same time, which usually drives me to the edge.
I hold out as long as I can-it feels so good-but then I tell her I'm going to cum. She leans back a little, opens her mouth, and sticks out her tongue. This is my cue to do the same. When I let loose, I usually cum in a few big blasts which shoot up my chest and sometimes splash my neck and face. I never know where it's going to go. Her eyes hold onto mine the entire time, until I'm finally spent and covered in cum.
