Desc: Erotica Sex Story: Physics, geometry and math in sex? Fun in math! Free at last, even the teacher learns. Am I pushing Lois too fast?

For the next many minutes, Sue spooned behind me while I kept my body entwined and pressed against Lois. Joe spooned her from behind, nestling his dick against her velvet ass. A soothing energy, an afterglow, surrounded the four of us, bonded as we were. Time passed quietly. About twenty minutes after Lois's first screaming orgasm, my dick's twitches told me it was anxious for another intense visit. "Lois, are you awake and ready for more?"

"YES, please! You MUST have hit my G to make me sing like that! This time, though, ummm don't be so gentle and loving. You can go slow NEXT time."

"Really? Oh, and you'll KNOW when I slap your G spot. So what would my novice whore like now? Anal? Or should I find my whips?"

"Whoa! You know I'm not ready now, if ever, for anal, and forget the whips! Isn't there something between?"

"Well, if you insist. Hey, YOU should know I'm just toying with you ... and opening your eyes. You can study my Kama Sutra later for interesting positions. Just don't pick the ones for double-jointed gymnasts. I can't do those. I want you to feel just a few more basic positions and variations, but soon you will go freestyle and combine positions to scratch whatever itch you feel. NO, I won't push anal until you're ready, and you aren't yet.

"In no special order, what I NOW hope to introduce to you are positions like these: you on top, facing me- on your knees, or with feet flat; you on top facing my toes; 69; me standing, you impaled on my cock with your legs on my hips; you standing and bent over, using furniture or not; DP - I'll explain that when you're ready to hear it, you aren't yet; anal; varied pussy entry from rear, like doggy, face down or legs on my hips; with two or three others; legs on my shoulders; THEN you can look at kinky and varied fantasies and fetishes! But, believe me, I'm not going to stay very structured for long. Look up 'sploshing' to see my next new goal with you. I just wanted you to get a sense of what I meant by having 'just begun.' I'd like to slowly add foods too ... yum! But no coprophilia or urophilia!

"We don't have enough time this weekend to sample and relish most of these even if you can stay an extra day. Believe me when I say that's MY loss too. I hope Joe will introduce you to several more before we hook up next time, and that you both keep me posted on my star student. Let's try basic 'doggy', but try to notice if or when you automatically change it a little. Truly FEEL the sensations, how they change, and if any are coming from your anus. OK, on all fours and give me your cute little ass."

Maybe if she can become aware of light anal stimulation and pleasure, she may be daring enough to allow more stimulation or even attempt anal sooner. As she quickly assumed the position, she thought to ask, "What do you mean THREE others? And all those are just the basics?"

"Shhhh, later. Tell us how you feel, facing away from me with your squirming ass open for us, and how my stiff rod makes you feel as it rubs down your ass crack to your moist pussy."

"Well, I feel vulnerable and naked to your whim, like I surrendered myself and am waiting to feel whatever you choose. Your hard dick feels teasing and exciting. Just the anticipation for it is making me hornier, almost desperate. So ... please, give it to me."

"Well put. Reach back between your open legs and smear my pre-cum over my dick. Uhhhh ... I ... can't ... tease you ... anymore or I'll ... cum right ... now on your back. You tell me 'harder' or not." My dick head automatically found its wet target and, like a high diver silently slipping into deep water, pushed all lips aside until it was submersed and warm. After a heady pause deep inside her, my hips pulled me out to her breach. I managed to pause a second before her sweet puss pulled me back in. Then my Mini Me abruptly thrust in one long quick stroke at full speed until stopped by her barely cushioning ass. Lois let out a loud yelp and we both gasped at the sweet clenching grip on my cock. A small wall mirror showed me her bulged eyes and shocked mouth. My cock didn't want to leave her deep warmth.

"Oh honey, how did you tighten your sweet, sweet puss so much? It won't let me leave, and Willy doesn't want to move again. You're so exquisite, I ... I can't open my eyes or breathe normally. Ohhhhhh, your fucking, twitching cunt is driving me crazy. I can explode in you right NOW, but I have to hold out." The pleasure was so intense, I teared up. Maybe because we were still primed from her last orgasm, or some other combination, I couldn't think. Some alien ferocity tore me out of her and pummeled me back in. My hips drove me hard against her ass and in just two such strokes, she was gasping loudly and slamming her ass against my thrusts. Our collisions were intense, yet I spread her cheeks to give me deeper access and to stretch her dark hole. My pubes grinded and twisted my hairs against her round muscle. I hoped that besides the primary joy thru her tender twat, she felt the novel pleasure from stretching and rubbing her virgin anus as well.

Apparently Lois was catching on. "HARDER, fassssterrr, harrrr ... uhhh..." My hips arched to slam her harder, muscles strained to go faster, sweat spewed from both of us. We both got louder and LOUDER, grunting, moaning, gasping. Before she could even adjust to the new position, she shuddered out of control, screamed and took me with her convulsions. My sperm flooded her pussy and we both bellowed and collapsed. Falling on her back forced my dick to noisily pop out of her sweet, quivering depths. We took a long moment to catch our breaths. "Ohhh, sweetheart, that was wonderful. So intense, fast and HARD, you brought me to another screaming orgasm in minutes! THANK you!"

"It wasn't quite what I intended or as hard as I planned, and just a little too fast. I blame you, sorceress! You took control and swept me away. What a rush. What a compliment. I have to desensitize myself a little since my dick head is still throbbing and deep purple. Here, let me rest my weary dick a minute between your sexy steaming thighs for their soothing, warm comfort. Lois, you truly surprised me. Each time you twitched, my tender cock tried to cum again. " After a long, quiet moment, I asked, "Tell us what you felt. Did you feel anything from your anus or notice the core of your pleasure?"

"Wow, just wow! That first thrust scrambled my brains and confused the hell out of me. It and that position were so many things at once - breath taking, sharply and EXTREMELY blissful, lustful and dirty, rewarding, it made my whole body feel full and yet debilitated. I guess my pussy spasmed on your dick causing your reaction, which fed mine, and I also almost came from just ONE FUCKING thrust! No, I didn't notice anything from back there. My puss was too excited and I'd say the core of my arousal is your wonderful Willy. Should I be afraid?"

"No lover, you're fine. I mean REALLY fine. Hey you two, quit your grinnin! We both relished it, so celebrate with us. Oh SHIT! Ding, ding, ding! I didn't look closely enough, but NOW I see! The way you're built, doggy on all fours puts your pussy at a great angle. When I pushed into your tilted puss in a slight downward angle, I hit right behind your clit, maybe on its shaft, and slid along your inverted pussy 'roof' right over your G spot. I told you earlier that I'd find it for you and Joe, and that you'd KNOW absolutely when I shook it. OMG! It's math! In sex? Hmmm, so it must be fucking geometry and fucking physics! Whoda thunk? Because of the speed of the first thrust, it 'shocked' your G. Lois, ... I need a couple of minutes and we can go again. Oh hell, in fact, I'm dying to go right now. If we do a slower, extended doggy you may reach what I wanted for you. OK?"

"Yes, master. Your wish is my command ... isn't that what Genie said? Seriously, you're telling me my G spot is THAT powerful?"

"Yes sis, it is. Before you guys fuck again, Lois, can I clean you up by sucking my husbands cum and your juice out of you? Joe declined, and we want you to experience being the feast today as we eat you." Lois nervously agreed, giving me a few more minutes to rest. She crawled backward to Sue until her dripping pussy was above her sister's face. Sue watched several large drops fall some inches into her hungry mouth. The lusty sight stirred us all. Sue asked Lois to spread her legs wider so her pussy would drop to her face. She had her nose against Lois's clit and her tongue invaded her cunt.

"Ohhhuggghhhhhhh..." Lois's deep, guttural groan of satisfaction drew echoes from all of us. Sue held her sister's pussy open and began hungrily sucking our mixed juices while simultaneously fingering herself and pinching her clit.

Her deep licks got longer and spanned from Lois's clit to her ass. Her nose rubbed Lois's rosebud and tried to gently pry it open. "Lois, relax your asshole so I can lick it better for you. I won't go inside so it will be safe for us; try to leave it partially open." Joe moved into place and helped finger fuck Sue until she spread her legs wide and relinquished her pussy for him. As she began squirming, Joe moved his nose against her clit and started eating my wife. It was a surreal sight - Sue's legs at almost 180 degrees, her swollen beautiful pussy splayed for Joe and his face in her fuck box. Lois looked back and saw the same surreal sight. I saw her first brief, annoyed reaction change to acceptance, then arousal.
