Chapter 2: Cathy and Nathan

"I'm about to head home, same time Thursday?"

"Sure, I still need to hit my forearms today though," I fist-bumped with John and he went for showers.

It took him only a moment to get out again as he said goodbye and went home. I locked the door behind him and shrugged apologetically at the girl Mark brought in again today -- Cathy? He was somewhat condescending towards her when he brought her in the first time, but she outlasted him today.

"I am sorry for locking the place up, but we should be closing soon and it is easier when people don't get in than to make them leave. When you are finished with your workout, just shout and I will let you out."

"Sure, I will, Nathan? Do I remember your name correctly?"

"Yep, that's me," I smiled at her.

"And what if I want to work out longer than you?" she raised her eyebrow.

"Sorry, but that is not too likely. I do have pretty high endurance," I flexed my muscles happy with the appreciative look I got from her.

"Well, I think we should test that endurance of yours sometime in the future," her smile was leaving very little to interpretation.

"I don't want to burst your bubble, but I have to say, you are really not my type, sorry," I shrugged. There was no use stringing her on, it was better to let her know right from the start.

"Sure, sure, Nathan," she waved her hand as if she'd expected it. "But I hope you can still give me some pointers about these exercises if I need them. Would you mind staying close and watch me as I work out? Mark did show me a bunch of different things, but I am still not sure about some of them."

"Sure, no problem," she would not be the first or last person I did this for.

I went for some dumbbells to the other room and when I got back, she was already working out on lat pull down machine. And her technique was horrible. I had her seating position adjusted, then angle of her back and finally the way she had flared her elbows out -- only after that she was able to do a passable exercise. I got back to my dumbbells for few minutes before she switched machines and I was forced to get up again and correct everything she was doing wrong. Not that I minded helping her with something, but she was doing everything almost wrong and I doubted even Mark would be so sloppy to not teach her absolute basics.

Machines, dumbbells, barbell -- everything was a problem and I spent more time correcting her technique than doing my own workout. I was almost able to get back in the zone, but then she went for a dead-lift and I was forced to stop and prevent her from hurting herself. I checked her posture, made sure her back was straight and forced her to do few slow reps to make absolutely certain that she gets what I was telling her. Only upside was that I could sneak a few peeks down her top which had modest cleavage, but her tits were so big, that the fabric was stretched to its limit and it was minor miracle that the top didn't burst apart yet.

After that exercise I was able to catch somewhat of a break and do few more sets of my own. Cathy finished with her barbell training and was dawdling around before settling on a machine she would use next. It was a chest fly machine across from me and I tried to not make a surprised or confused face. Girls mostly avoided doing any kind of chest work here in a first place, but more importantly, when considering her previous exercises, there obviously wasn't any program or planning behind them. She just picked something at random and went with it. I debated telling her something about it, but I felt that I've already done enough for the evening and it was better for her to just move than not. And additionally -- this exercise was doing something pretty interesting to her chest. If I was worried about her top tearing before, now I was unsure what was even holding that thing in one piece.

"Am I doing something wrong again?" she asked loudly and looked really frustrated.

Only then I realized that I was probably staring at her chest for a good long time and she might have felt uncomfortable. I covered my embarrassment with a cough, put a frown on my face and went closer to inspect what she was doing as I've done times before and she did not complain at all. I prodded her to continue with her chest fly exercises. From up close her chest was looking even more impressive and I had trouble concentrating on the technique. It was complicated by the fact that she was executing this one almost perfectly, so I really had to nitpick and correct the slightest errors. Someone more experienced would probably notice that, but since she was a complete newbie, I was pretty safe and after I have corrected her enough to cover my faux pass, I turned to go back to my dumbbells.

"Would you mind watching a little longer? I am still unsure if I am doing this right," she asked sheepishly.

"Of course, if I can help you in any way," I looked back at her and smiled.

She kept her moves steady and slow, exactly as I have instructed and complimented that with deep slow breaths in the exact rhythm of the exercise. I wasn't really objecting about the opportunity to inspect her up close. Each breath expanded her top so much that I could clearly see outline of her nipples and every move was doing very interesting things with her chest.

"That's it, Nathan. I want to keep looking and keep checking that everything is in order, can you do that?"

"Yes, of course I can," I nodded automatically. I was there to help her and it was easy to just keep watching now.

"Very good, it took some time, but I think we are almost there. How do you like my music?"

"It's fine," I shrugged. I barely noticed anything playing at all.

"I am glad you like it. It might sound ordinarily, but there are some pretty special sounds in the background. They help people to concentrate more on what is important."

"What is important?" I asked confusedly.

"Yeah, you wanted to help me, so you better concentrate on me."

"I uhm..." her hands moved over to her breasts and I was lost for words.

"I noticed your interests a while ago, so this should look pretty captivating to you," she pulled her top lower and showed me more of her big boobs. I opened my mouth to react, but she didn't let me speak and massaged her breasts over the fabric, which looked very interesting.

"So, I guess we have safely established that you are a boob guy, right?"

"Yeah," I nodded again, somehow unable to do anything else.

"And you've said that I am not your type, but that doesn't matter when it comes to boobs, right? You still enjoy looking at these, don't you?" her hands were still moving around which resulted in huge sways of her breasts back and forth.

"Yeah, I like looking at them," I always considered smaller breasts to be cute but there was something so monumental about her rack, like it had this unbeatable pull and I was fascinated to a point I could not look away.

"Look at you, big guy. If you like watching them that much, you should get even closer, how about that?" and she pointed towards floor.

"Okay," I was happy to hear that I can watch her giant boobs from up close and knelt down. For a moment I considered this situation a little weird, but once she proceeded with their fondling, all my doubts went away. My face was just inches from those breasts and I could easily touch them if I wanted, but for some reason I felt passive and happy to just watch and enjoy the view.

"You are such a good boy, Nathan. So, you realize now that you like my boobs the same as any other breasts, maybe even more. You'll find out that watching my boobs will always put you into a good mood and you will want to spend more time with me. Do you understand?"

"Yeah, watching your boobs is great," I nodded happily. It was amazing how good it felt to just look at her hands massaging them.

"And if you like my breasts so much, you will like also other things about my body. For example, look at my lips."

It was impossibly hard to peel my eyes from her breasts, but at the same time, I was unable to resist her suggestion and looked up to her face. I noticed she was wearing a light pink lip gloss and her lips were shining because of that. In addition, she slowly licked them with her tongue and that little bit of moisture made them look that much better.

"See? My lips look like any other girls, so it's no wonder, that you like them too. I bet you want to taste them right now, don't you?" she smiled.

"Yes, I want to taste your lips," I responded as soon as I realized it is true. I did not wonder about them up until a moment ago, but now they looked incredibly attractive.

"But I have to warn you, my kiss will taste better than any other girl you have tried before, but it is also highly addictive. You will want to kiss me more and more. And you will also find me more attractive every time you kiss me. What do you think about that?" she licked her lips again.

"Is that even possible?" my mouth was dry and her lips looked even more appealing, but her words were unsettling and sent shivers down my spine.

"Yes, it is absolute truth. You have no reason to doubt my words, right?"

"I have no reason to doubt your words," I nodded and wondered why I was thinking anything else up to a moment ago. Her lips were addictive and would make her more attractive to me with each kiss.

"But the thing is, even though you know all that, you are still unable to resist my lips. You want to kiss them right now, don't you?"

"Yes, I want to kiss your lips," she saw straight through me.

"Such a big, strong guy and you cannot do anything to resist me? That's what I like to see," she laughed loudly and then moved a little closer. "Well then, kiss me now."

I felt a stab of panic as I realized that if I do this, I would be unable to control myself. If her lips had this magical power, I would... My train of thought was interrupted, when she moved even closer. I felt her hot breath on my lips now and her closeness had overwritten my concentration. Her lips were looking so tasty and I moved to meet them. She inched away and giggled like a little girl. I knew she was mocking me now, but it did not matter a bit.

I moved again and this time her lips met mine. I planted a soft kiss on them, little uncertain about what it might do to me, but all my worries were washed away because she tasted simply divine. Her tongue flicked out and licked my lips and I realized it was true. She tasted better than any other girl I've kissed before. My hesitation disappeared and we were suddenly making out. I was not sure how long it lasted, but after a while, she moved away and put her finger on my lips.

"Look at you, Nathan, you can't keep away from me and we barely started, are you sure, you don't find me attractive?" her smile was more confident now.

I was breathing heavily and while it was hard to get my bearings, I looked at her again and realized that I was probably too harsh in the first place. She wasn't really my type, but there was something appealing about her. Like a kind of magnetism that just pulled me closer to her. And her kisses were amazing to a point I was already missing her lips. "Well, I..."

"Uncertain, aren't we? Let's change that, kiss me again!"

This time her words sounded like a command and I wasted no time. Our lips met again and her tongue was now aggressively exploring my mouth to a point I almost felt violated. But then I was overwhelmed by her divine taste and just went with the flow of the deep kiss. Again, it was her who broke the kiss and moved away.

"Well, what do you think about me now?"

It took me a moment to catch my breath, but when I did, it was almost like I was seeing entirely different person before me. It was still Cathy, but somehow changed, more appealing, hotter and it was difficult for me to take my eyes from her. "You look... Nice," I cleared my throat.

"Nice, eh? That is quite a difference from where we started, wouldn't you say? But if you want to kiss me again, you have to earn it. Let's see, how about you remove one piece of clothing for each kiss?"

I didn't even think about it and my shirt was first thing that had to go. And each time I stripped something; I was rewarded with a kiss that was too short for my tastes. It took just a few minutes for me to end up totally naked in front of her. I was still on my knees, but it hardly even felt relevant at this point. She looked so amazing and I was hard from just looking at her and receiving few kisses. I couldn't believe my luck to find a girl this hot that was interested in me and damn, she was an amazing kisser. I just could not get enough.

"Someone got really excited here," she smirked mockingly. "But I am not done with you yet. I want to see you play with yourself. Slowly and just watch me get ready for you."

My hand was already near my cock and I started to stroke just as soon as she told me. This was as far from normal for me as possible, but there was just something about her that made me respond to her suggestions. Meanwhile she removed her top and I could finally see her giant boobs in all their glory. It was almost too much for me to handle, seeing those huge F cup breasts right before me.

I didn't have time to admire them, because Cathy swiftly stripped her gym shots and underwear with one pull. My eyes went down to her crotch with a neatly trimmed thin patch of pubic hair and her pussy lips were already glittering with arousal. I was stroking even faster because she looked incredibly hot.

"Well look at you, Nathan. All this effort and all those muscles of yours totally at my disposal. Just a few kisses and you literally can't keep it in your pants. Lie down, I want that cock of yours inside of me right now."

The rubber floor felt cold against my back, but I did not complain because it wasn't important. I could concentrate only on Cathy as she lowered herself on me and I felt my dick entering her pussy. There was no resistance, I just slid inside as she wiggled around to find the position she wanted and then she began to ride me. Her hands were running along my forearms, biceps, then chest, my stomach and even thighs. I tensed my muscles, but I felt like that was only thing I could do. While she picked up the pace and I was doing my best to keep up with her, my eyes kept sliding from her breasts to her lips and I just took in her beauty. She was riding me hard and my hands on her hips were barely able to contain her.

"Looks like you are really enjoying this, Nathan," she slowed down a little to catch her breath. "Well so do I and as long as you keep working on those big muscles of yours, we can keep doing this. I need my toys in good shape after all," she smiled hungrily and proceeded with the grinding of her hips and it felt incredible.

My hands were roaming her body and my dick was about to explode, but we both knew who was dominating the situation. I could not keep my eyes from her boobs, kept thinking about how amazing she tasted and I realized I would do anything to do this again and again. She reached climax atop of me, and I knew I would continue to work out and get bigger because Cathy wanted her boys that way...
