So, this is part 3 of my series. It's a pretty fun part because it has the narrator and Erin getting more experimental and crazy.
The reason it's been so delayed is that my classes really kicked my butt and I wasn't able to write much if at all. But, I finally have it done, so enjoy!
On Saturday, Erin came over to my apartment unannounced. Needless to say, it was a welcomed intrusion. She was wearing a green sundress that perfectly complimented her eyes. Her hair was glowing in the intense light of the sun. She got on her tiptoes and pecked my lips and smiled.
"What's the special occasion?" I asked.
"What? I can't wear a dress without my boyfriend questioning me why I'm wearing it?"
"I just never see you in a dress. I wish I could see you in them more often."
"I guess you will then. Whatchupto?" she asked.
"Doing calc homework."
"Need help?"
"Sure, but don't help too much. I have an exam coming up next week so I need to do some work myself."
We went into my bedroom at sat down at my desk and worked for about an hour. During that time, Erin did what she was supposed to by offering a minimal amount of help, and not being too distracting. After the hour though, she grew more restless and a little frisky. When she was helping, she pressed her boobs into my shoulder and very frequently touching my inner thighs.
Finally, I reluctantly stopped her. I wanted to get my homework done before "hanging out" with her. "Erin, let me get my homework then we can do whatever you want."
"Well, it's not my fault we're alone in your bedroom. Let's go to the library or something, that way I'll be less tempted."
I agreed and I packed my stuff and drove us to the library. We chose a relatively empty part of the library since we didn't want to disturb the others around us. We were most likely going to chat quite a bit.
Again, I began working with Erin helping out every now and then. After about half an hour, she got up and announced she was going to the ladies' room. A few minutes later, she came back and sat down next to me. When I looked up at her, she had an evil grin on her face, and I sensed that this study session wasn't going to last long at all. Regardless of that, I carried on working diligently until Erin held my hand. Without explaining her intentions, and not really needing to, she pulled my hand down to her crotch. I looked around me but thankfully no one was looking our way. As she drew my hand closer and closer to her sex, I got increasingly nervous, and increasingly excited. Finally, I touched what Erin wanted me to touch. I expected to feel the soft fabric of her panties, instead, I felt her bare skin, freshly shaven and so incredibly warm.
Against my better judgment, I explored further downward until I reached her clit. She shifted her hip forward slightly so I had easier access to all of her. I dipped my finger deep into her and she inhaled deeply but quietly. At this point, I was too excited to care about the people around us or the homework that I had to get done. I carried on fingering her, periodically removing my finger and rubbing her clit. I kept the clit-rubbing to a minimum because that made her whimper or moan way too loudly for the quiet environment.
Her hand found its way to my rapidly hardening dick. My jeans were a little tight so it was very obvious that I was excited. She rubbed the considerable bulge with an unusually high amount of pressure, trying to give me the most sensation she could through the two layers of clothing. It wasn't the most pleasant sensation ever, but it worked for me and soon I felt the cold wetness of precum building up in my boxers. I couldn't help it anymore. I needed to be in her else I was going to explode in my pants.
"Let's find a less populated spot," I whispered to her. She smiled, knowing she had got my full attention. I quickly packed up my stuff and walked with her around the library. It was a huge place, and since it was a Saturday morning, there weren't that many people there. Finding an unpopulated area wasn't hard at all. When we were sure that there were no security cameras around and that we didn't spot any more people, we made out furiously but silently. Our hands instinctively worked their way to each others' cores, further hastened by the pent up sexual tension.
She unzipped me and pulled my hard dick out without breaking the kiss. I had easier access to her though. I reached under her dress and found my target. The moment I started rubbing her clit, she stopped kissing me and buried her face into my neck. She was still holding my penis, but she stopped reciprocating and gripped it tighter. She started kissing my neck slowly while breathing hard. I yearned for more attention to my crotch, but Erin was obviously thoroughly occupied, not to mention I was really enjoying watching her try to keep quiet. I continued on rubbing until she put her hand on my wrist.
"Stop," she whispered, "I'm about to cum."
I did not obey this time. I wanted to see her struggle to keep quiet. I sped up my motions which made Erin tighten her grip on my penis and wrist more, but that didn't hold me back. A few seconds later, her grip slacked a little then tightened almost painfully around my wrist and dick. Her breathing got raspy and her body tensed and shook. I put my free arm around her and pulled her to me, but I still kept rubbing her clit gingerly as she shuddered and tried to muffle her moans. When I knew she couldn't take it anymore, I stopped my pleasurable torture and let her regain her composure. She stood there for a few minutes, panting as though she just ran a 100m race.
"You're an ass," she said, finally breathing softly enough to control her whispers.
I smiled proudly and whispered back, "I know."
Seeing the smugness on my face, she dropped to her knees and took me into her mouth. She used her mouth and hand in tandem to get me to climax as quick as possible. It certainly was working, although I was nervous about being caught so it would take me longer to cum. She patiently worked on though, stopping every now and then to glance around us to make sure no one was around. I couldn't blame her for being cautious because I wasn't focusing too much on looking out for spectators. I wanted to cum as quickly as possible to minimize the risk.
After some time, I was ready to cum. I let Erin know, and instead of finishing me with her hand, she continued with her mouth. She moved her hand faster and I felt my orgasm rapidly approaching. Soon, there was no turning back. I grabbed a desk next to me, bracing myself for impact. Then, it hit and my knees almost gave away. She didn't back away so I cum in her mouth. After I was done, I quickly zipped up my jeans and helped Erin to her feet. She pulled out a paper towel from her purse and spat out my load onto it and threw it away.
We walked out of the library quietly and slightly embarrassed, although we were pretty sure no one saw us. When we got into the car, we both burst out laughing and kissed.
