Playing with Cynthia's tits

I decide the first step is to start to include erogenous zones I've pretty much ignored until now. I reach down and grab a hold of one of Cynthia's big tits. The soft flesh of her magnificent udders presses between my fingers as I start to knead and caress the soft flesh, while I continue to keep up soft thrusts into her. For better access, I flip her from her side onto her back and replace my hand on the tit, while my mouth starts to suck and kiss the other. I quickly find her erect nipple and start to suckle, while my fingers tease the other nipple.

"Aah!" Cynthia moans. In the past, I have been able to get her to cum just by playing with her tits. It takes a long time and a lot of effort, so I usually don't bother, but assaulting her tits is a good strategy if I want her to cum while fucking.

Cynthia lets out another moan as I continue to fuck her while her stiff, long nipples are receiving my attentions. My tongue plays against the firm flesh, flicking it, licking, feeling the bumpy flesh of the areola surrounding it and the rough texture of the nipple itself. As the tip of my tongue flicks over the top of the stiff nipple, teasing the milk duct, my hand is busy firmly squeezing the other tit. I put pressure enough on the tit that she feels it without hurting her, then move to tease the nipple, running my fingers around it, flicking the nipple, stroking along it, lightly squeezing between my fingers. Then I switch, my mouth going to the breast that I was fingering and my other hand to the wet tit.

I've barely begun again after switching when I feel Cynthia moan and her body shudder as another orgasm wracks her body. I continue to play with her tits through her orgasm.

All through this, I had only cum once and while that once had desensitized me somewhat I was well past ready for my own orgasm. I had been trying to stave it off as long as possible but as I felt Cynthia's pussy clench up on me in response to her titty orgasm, I was pushed past my edge. I let go of Cynthia's nipple and groaned as I pull out of her twitching pussy. Burst after burst of cum erupts from my dick to cover Cynthia in my seed from pussy to tits. Spent, I lie down next to Cynthia and take a moment to recover.

After a moment, I hear Cynthia mumble something and notice that she has her eyes closed, her body occasionally twitching, leading to moans. Cynthia has been successfully fucked into unconsciousness. I grin to myself, though I am a bit surprised it didn't take more.
