Liz takes charge and shows 'em.

Just when I thought Michelle and Matt had worked things out, Michelle had decided she needed Matt to demonstrate his good intentions. When he was slow to respond, she decided I could help her show Matt what she needed to come.

Michelle was tugging at her tight purple sweater. Matt was looking stunned. I didn't know what to say to all this. How was this going to help them? On the other hand, the little man in my pants was voting a strong yes to Michelle taking off her clothes.

Liz stood up to her full six-foot height and held her hands up. "Timeout, Michelle," she said. Her usual carefree expression was replaced by a serious one, and her big brown eyes looked steadily down at Michelle. "Now where were we?" she said. "You and Matt made up, you decided to work things out, and you suddenly hit him with this?"

Michelle turned to Liz and said, "I need to know for sure!"

When she turned, I looked at Michelle's round backside, poured into her tight slacks and shifted uncomfortably.

"Okay," Liz said. "Here's what you said. You used to get off with your boyfriend all the time. You can't do it with your fiancé. You don't know what the problem is, because you're using all your favorite foreplay and sex positions that used to work for you."

Michelle crossed her arms over her chest. She nodded, "I'm doing everything that used to work. I just don't think Matt is trying hard enough! HE always comes."

Matt looked sheepish, but I could see his pants bulging too. His light-colored slacks, from the same designer as Michelle's, did nothing to hide his little issue. He started to say something, but Liz waved him down.

Liz asked Michelle, "Okay, so did you consider there might be something other than attitude involved?"

"What?" Michelle asked, her hands going to her hips.

"Fit," Liz said.

"No way," Michelle replied. "They're both, um, big enough, but not too big."

"Gentlemen," Liz said, addressing Matt and me. "We have an issue I think you could help us resolve very quickly. Could you stand up next to each other here?" Matt and I looked at each other, shrugged, and stood up beside Liz. I didn't exactly tower over him, but I was a head higher. "Now, I think Michelle needs to see this comparison side by side," she said. "Could you open your pants and show us what you've got?"

I gulped. Matt coughed. "OK," he said.

"Guess so," I replied.

With a jingle and a couple of zips, we were standing side by side, cocks out for inspection. I couldn't help thinking of the Marine boot camp discipline where a recruit who talked of his weapon as a "gun" had to walk the rounds of the camp with his pants open and recite "This one's my rifle, this one's my gun, this one's for fighting, this one's for fun."

Matt and I both had the same reaction to the inspection, going from semi-hard to fully hard with Michelle's and Liz's eyes on us.

"Geez, Michelle," Liz said, "Don't you think there might be some differences of fit there?"

We eyed each other's tools. Matt's was an impressive eight-inch spike with a pointed head still cupped by his foreskin on a slim, smooth shaft. Mine was a respectable six-incher with a blunt knob of a head on a veined shaft half again as thick as Matt's.

"Um," Michelle said, "Maybe so."

"At least with that difference you might want to try a position with your legs together," Liz suggested. "Or have him put one leg inside yours and one outside."

"Do you really think that would work?" Michelle asked, looking hopeful.

"I think you have to try an angle that tightens you up," Liz said. "But I'm not speaking so much from experience since I've had the opposite problem more than once."

"What did you do?" Michelle asked.

"A pillow under my butt, my legs wide open, and lots of lube. I never go anywhere without my Slippery Stuff," Liz said.

I wondered if it was safe to tuck away my boner. Matt's was still out, so I waited.

"Matt, do you want to try it?" Michelle asked. He shrugged and nodded. "Liz, how do those positions work?" she asked.

Liz tried to explain with gestures and descriptions. Michelle and Matt just looked more confused. "All right then," she said, "Let me show you." She sat on the bed. "Hey, come on over, I need your help," she called, beckoning to me. I stood up. "You can put that away now, we can do this fine with clothes on." I tucked my semi-erection away again.

Liz continued, "OK, Michelle, basically what you're after is to end up with Matt inside you with your knees together. Here's the first way to do it." She lay back with her legs apart. "C'mon Tiger," she said to me. "Lie on top like you're doing me."

I didn't need much encouragement. I climbed up on the bed, my legs between hers, and pressed my pants fly to hers. My cock twitched as it stiffened up again. A beautiful sun-bronzed blonde woman with big, long-lashed brown eyes, whose touch gave me sexy little shocks at the rehearsal, was asking me to lie on top of her. I'd had worse days.

"OK now I'm starting to bring my legs together," Liz said. "Pick up your right knee," she said to me, tapping my leg. I lifted my leg, and she slipped one in between. "You see he's got only one leg inside mine?" she asked Michelle and Matt. "That might help, because it presses harder on the clit," she said.

"Huh?" Matt said.

"Grind your hips a little," Liz said to me. I pressed my hips down and forward a couple of strokes. "Oh yeah," she said. "OK stop. Maybe you can see he's pressing a little harder than if he had both legs inside mine?"

"Oh." Matt said. Michelle giggled.

"OK, now the next step," Liz said. "Other leg out." She tapped my leg, I lifted, and I was left straddling Liz right below her hips. "That's the position," she told Matt and Michelle. "Try grinding again," she said. I tried a few thrusting motions. It was more awkward with my legs apart, but not too bad. "Ah." Liz said. "Hmmm. OK that's good." I stopped. I really wanted to adjust my underwear, but we were sort of in the middle of things.

Liz went on with me to demonstrate a position with her on all fours and me kneeling behind her, with my knees outside hers again. The last variation was with her lying on her side with her knees drawn up and me lying on top of her, with my pants fly against her butt again. She seemed to be pressing back at me. At least this one put our heads together. I whispered, "Where did you learn all this stuff?"

"Peer counselor in the college dorms," she replied softly. "This is just the basic stuff."

"Was it just a lucky guess it that Michelle was having a problem with fit?" I whispered.

She whispered back, "Uh, no, I'd already seen Matt's cock."

I had lost track of what was happening with Matt and Michelle, since I'd been facing the other way all the while. I hoped that with all this effort we were going to, they were getting all this. "How's the audience doing?" I said quietly.

Liz turned her head slightly to check. "Oh," she said.

"Oh?" I said. I looked around. "Oh."
