Swapping Undies

End of Part 2

"Did you like that?" Ally asked.

"That was wonderful." I said breathily.

"You want some more?" she asked.

"Absolutely!" I said eagerly and began to lean down to take her lips again.

But she stopped me placing her finger on my lips. "Only the first round was free." she said as her cute innocent grin took on a more mischievous look.

"What do you mean?" I said confused.

She moved around me and picked up the thong that I had dropped on the sofa. The mischievous grin was back on her face as she asked me, "You sure you don't' want to wear this?"

Part 3

I was completely in shock at the sudden turn in the situation and had no idea where any of this was going. But I knew I was in too deep now to back out. That kiss and those big brown eyes gazing into me just before had forever changed the way I'd look at her. I tentatively took the thong and started to move behind the sofa like we had done so many times the past few weeks. I was surprised when she grabbed my arm and stopped me.

"No do it right here. I want to see you put it on." she said. Her sweet gaze and eager look melted the little energy I had to argue so I slowly unzipped my cargo shorts and let them drop. Thankfully holding and kissing her a few moments ago had me sufficiently hard to create an impressive bulge against the front of my briefs.

"Wow! Very nice!" she said before pushing her hands under my t-shirt and pushing it up. I grabbed the sides and pulled it over my head and tossed it to the side. She eyed my chest and flat stomach with what could only be described as a hungry aroused look before quickly inserting her thumbs into the waistband of my briefs and pulling them down. My erection sprang free from the thick confines of my sport briefs and pointed itself straight at Ally, and she was quick to point it out.

"Wow! I guess you've always liked me more than you let on." she said coyly as she eyed my hardon. She then reached out and rubbed her finger a few times on the tip of my penis sending electric jolts all the way down my cock.

"Woah!" I moaned as she teased the tip of my cock.

She giggled as she said, "Wow you really are worked up." Then she gave me another devilish grin as she picked up the thong again and said, "No more until you're wearing this." I was way too far gone to resist at this point, so I meekly took the thong and pulled it over my legs and pulled it up under her amused gaze.

As I got the thong up around my waist, I felt the strap pull between my cheeks and tried not to wince. Thankfully Ally had chosen a higher cut thong, so my erection fit in the soft cotton, but it was quite close. Any more growth and I risked poking over the waistband.

Before I could try to acclimate myself anymore to wearing a floral print thong I heard Ally gush, "Damn you look so sexy in that!" She was on me a second after that and we were making out like a couple of horny teens. Our hands were all over each other and soon she was manhandling me back onto the sofa. She straddled one of my legs as we continued our hot and heavy make out session. We kissed fast and hard for several minutes before we were forced to stop in order to breathe.

As we stopped kissing, I melted back into the sofa cushions, and she slumped onto me her head leaning into my shoulder. I wrapped my arms around her and held her tight was we both tried to catch our breath. It was a little awkward and uncomfortable and would have been better on a bed, but I wasn't about to complain.

After a few minutes of us catching our breaths, she moved her head and gazed up at me with a look of affection on her face. I couldn't help but grin at her.

"Is this what you had in mind when you started swapping undies with me?" I asked.

"Well partially." she said as she gave me a sly smirk and sat back up and nudged her knee that was between my legs right up against my hardon and moved it up and down a few times.

Now I would have had to be a complete idiot not to know what else she wanted at that point given the position we were in. But I couldn't help but press my luck just a little more.

"Why does my leg feel wet?" I asked feigning innocence. She was basically sitting on one of my legs straddling it with hers and I could feel a slight dampness through her cotton running shorts.

She gave me yet another wicked grin before saying, "The same reason your panties are about to be wet." She then moved her knee back and started stroking my hardon.
