Dorsai - Taxi

Helens breasts were swaying slightly in sympathetic reaction to the motions of her hips and pelvis; but not so much that I couldn't keep her nipples between my lips, or change from one breast to the other. That gave me the freedom to use my hands to re-explore the rest of her amazing body.

After delighting in the feel of the rest of her body, my hands finally settled on squeezing and caressing her incredible ass. Each time she arched herself down onto my cock again, I could feel the muscles under my hands clenching under the warm smoothness of her skin. Helen had started her own version of the body-tensing thing that Sarah had demonstrated, and I knew that she was moving toward her first climax since she'd climbed on top of me. Remembering what she'd said about not 'pushing' them, and what I'd replied about not knowing what their limits were, I decided to do a little experimenting.

By reaching around her a little farther, I was able to slip the end of one of my fingers through the oils that overflowed from where we were joined. With it suitably lubricated, I them ran it up the crack of her ass – and particularly across her anus. The reaction I got from that little test was considerably different than anything I'd expected.

I'd thought that if Helen didn't like it, she'd simply tell me not to do it again; if she did like it, the most I anticipated was some small noise letting me know it was okay to continue.

What I got was a near-scream of "Ohgodyes!"

Getting that kind of response from her, I didn't delay in repeating what I'd just done – with the addition of pressing a little harder against her rectum. She let me know, rather enthusiastically, that she welcomed my second effort, as well. That was all I needed, and I began transferring as much of her lubrication as I could to the pucker of her anus and carefully applying it not only to the outside surfaces, but working it into her opening as well.

While I was engaged in that little task, Helens passion and arousal steadily increased along with the frequency and intensity of the spasms coursing through her. An idea came into my mind, and I quickly went about preparing to put it into action.

So I was completely ready when Helens body finally froze over me as her body tensed with the start of her climax. After the first wave of release washed through her and her body relaxed slightly, I quickly slid my well-wetted middle finger through her back opening and tried to bury it in her as far as I could.

Her reaction was immediate, and extreme: she threw her head back, the tendons of her neck standing out like steel cables in a (thankfully) silent scream of pleasure while her entire body froze in place. That included the muscles of her vagina, which suddenly tightened her so much that I was almost afraid they would force my erect cock out of the warm confines of her womanhood.

She stayed like that for several long seconds before she went through a series of intense spasms that were duplicated around my erection. It was the most amazing thing I'd ever been privileged to witness and experience up until then; and I've never been involved in anything quite like it since.

When it was over, Helen nearly collapsed on top of me; and when I carefully extracted my finger from her nether regions, her body spasmed yet again in response.

I wrapped my arms around her and held her limp form as she panted into my chest. Down toward my feet, I heard Sarah solemnly announce "I've never seen Mother cum that hard! I could see that she liked it, and everything; and I could hear what she said when you started touching her… there, but I didn't think anything like that would happen to her!"

Directing my voice in the general direction of Sarah, I answered "Honestly, I didn't either. I mean, hell, I was surprised when she reacted the way she did when I just touched her there the first time. Do you think she's going to be okay?"

I heard Sarah's soft laugh before she replied "Oh, yeah, I think so, even though that was the hardest I've ever seen her cum. Usually, after she has a really good one, it takes her a while to recover, though. I think it's going to be even longer after that! Why? Are you uncomfortable, or is she too heavy or something?"

"No, I'm not uncomfortable, and she's certainly not too heavy. Matter of fact, it's kind of nice just holding her like this. I just wanted to make sure that everything is going to be all right."

Just then, Helen managed to whisper "Damn you, Jim! Yes, I'll be okay – after my heart quits beating like a jackhammer and my muscles stop feeling like they're made out of rubber bands. There I was having a very nice orgasm, thank you very much, when you went and stuck your damn finger up my ass and tried to kill me with a climax!"

I heard Sarah's soft snicker as I gently hugged Helen before telling her "I really wasn't trying to kill you – honest. You just seemed to like what I was doing, so I figured you might like that, too."

"No, I know you weren't trying to kill me, dear Jim. And I'm really not upset with you about it – ANY of it. Yes, I did like it, as you say. It's just that I've always been sensitive there; even more so when I'm with someone, and what you did caught me by surprise. It felt damn good, but it was a surprise, none the less. You're being a perfect dear to hold me like this, and be worried about me and that you'd somehow done something wrong – you most certainly didn't. But I have to warn you that it's going to be a little bit before I'm ready to have another try with you!"

I knew that Helen heard Sarah's soft laugh when she told her daughter "Go ahead and laugh if you want to – but I'll bet that he could make YOU feel something like that, too, if he wanted to!"

When I saw Sarah sit up, the expression on her face was a mixture of amusement and anticipation as she asked "Mother, is there anything I can get you? Or you, Jim? Something to drink, or eat?"

I could hear the humor in Helen's voice as she answered "I think I need about a pound of steak to get my energy back, and a gallon of some kind of sports drink would be good. But I'll settle for a soda or two and some snacks if Jim will help hold me up."

I softly stroked Helens back and told her "I'd be glad to" before letting Sarah know that something to drink would be appreciated. I watched as Sarah climbed off the bed on her mission of mercy; Helen felt the movement on the bed as her daughter left, and began to get up – only to realize that my erection was still buried in her.

Lifting her head to look into my face, she demanded "Christ, you're still hard? Even after that?"

I gave her a small kiss on the lips before answering "Obviously, I am", prompting her to stick her tongue out at me before carefully lifting her hips to separate us. With only a little help from me, she was able to sit on the bed long enough for me to get myself situated so that I was resting against the headboard before moving to sit on my lap with her back resting against my chest. When Sarah came in with some drinks, she saw that my penis was still erect enough to lie along her mothers cleft – causing her eyes to widen in amazement.

Sarah's eyes stayed locked on my penis except for the few moments it took her to set the drinks on the night stand and tell us "I'll be back in a minute with the rest…"

When she returned, I'd softened a little – but was still fairly close to fully erect. Helen saw where she was looking, and told her "Yes, the son of a bitch is still damn near hard", the tone of her voice telling me that she meant the comment on my parentage as a joke, before she added "He was still as hard as I could have wanted until we got switched around like this. I don't know how he does it; I'm just glad he can."

Sarah set a couple more sodas on the night stand, then handed Helen and I each a warm pocket sandwich. I took a bite, and was surprised to discover that it was actually a fairly tasty barbecue beef.
