My sister’s flatmate – Chapter 05 – Checking some boxes by BurningAlex

“Oh… It’s when you use a strap-on to …. me.” I said weirdly shy.

“Would you like that?”

“Just thinking about it makes me hard”

She laughed and grabbed my semi erected cock through my trousers. I tried to concentrate on the traffic in front of me while she moved her hand up and down my stiffening member. When we arrived at the Mall I was ready to fuck her. We entered the parking garage and I passed the first few free parking spots.

“There were a couple free spots at the entry.”

“I know. But we need one in the back where we have a bit more privacy.”

She understood what I want and started to open my fly while I was still driving. I pulled into the first free parking spot I saw, that was far enough away from entries. I turned towards Liz and started to kiss her. I put my hand under her shirt and fondled her tit. When we parted from our kiss she moved down and took my cockhead in her mouth. I leaned back and enjoyed the sensation of Liz’s tongue dancing around my cock. From time to time I was looking in the rear mirror to check if anyone was approaching our car. Since that wasn’t the case I closed my eyes after a while and totally focused on Liz’s head moving up and down my member. Her tits were bumping against my upper leg while her lips were pressed against my cock. I got closer and closer to cumming and my moaning got louder. Suddenly I heard another sound additionally to my moans and Liz’s sucking sounds. It was the sound of another car. My eyes shot open and I looked into the rear mirror again. Shit.

“Someone is coming.” I said to Liz. She pulled her head up and looked through the rear window.

“Shit” she added when the car was turning into the parking spot next to us. I quickly put my cock back in my trousers and Liz readjusted her underwear below her shirt. As soon as the guy pulled into the spot Liz was jumping out of the car and pretended that we had just arrived. She greeted the man and looked in my duration. I followed her while I was still trying to hide my boner.

“That was close.” Liz giggled as soon as we were out of range.

“Do you mean the guy or my orgasm?” I laughed.

“You were that close already?”

“You are getting very good at what you are doing.” I said while shrugging.

“However we ticked another point from the Todo list.” Liz said, “But I’m a bit horny now too. The whole situation really turned me on. In my Phantasie I also would have liked it if he had seen us.” Liz concluded. I couldn’t believe what I was hearing. According to the app Liz doesn’t like to involve other people and now she is suggesting it. I got a bit confused but also got even more interested in figuring out where this sex driven journey will end.

We walked through the mall and looked into a couple of shops. I was searching for a new pair of jeans so we ended up in the changing room of some shop. Liz sat down on the bench and watched how I tried on multiple jeans. After we decided on one, I opened it and pulled it down. When I wanted to step out of it Liz pulled down my underwear and took my limp dick in her mouth. She sucked it in and ran her tongue along the underside. It started to grow. As soon as I had a full on erection Liz released my cock and pulled my underwear up again.

“That’s unfair” I mentioned while stepping out of the jeans.

“Why is it unfair?”

“It’s the second time you have started but I haven’t had an orgasm.”

“So you didn’t enjoy it at all and I should never do it again?” she asked with a weird grin on her face.

“No that’s not what I mean… It’s just . .. you know …. It would be nice to let some steam off.”

“Maybe later” she said and opened the door to our changing room. I quickly pulled up my pants and followed her. Luckily no one was standing in front of it.

We walked further through the mall and got some food. I saw a Dessous shop and asked Liz if we should take a look.

“It’s super expensive, I don’t have money for this.”

“If you allow me to choose, I will buy it for you.”

After some back and forth she agreed and we entered the store. I haven’t been in one of those stores for a while and was surprised by all the hot outfits. We walked through the aisle and I picked up an outfit here and there. All of them were super hot and just picturing Liz in one of them got me a hard one again. We went to the changing rooms and were about to enter one of the stalls.

“I’m gonna try them on my own. You can wait outside the store.” I looked at her confused but she just shut the door in front of my face. I left the store and sat down in a nearby cafe and got myself a coffee. It was not the best coffee but my mood was brightened when I thought about Liz. How she was standing in the stall, looking at her nearly naked self in the mirror. I got an idea and texted her in our naughty chat:

“I dare you to leave the store without your panties on.”

I saw that she read the message but I got no response. Over half an hour later I saw her leaving the shop with a bag in her hand. I stood up and waved her to my table. She sat down next to me and ordered coffee and a piece of cake.

“Which outfit did you choose?”

“That’s a surprise.” She smiled at me. She grabbed my hand and pressed something in it. I looked at it and quickly hid it, when I realized it was her panties. She really did it. I leaned towards her and kissed her neck. Then I whispered in her ear.

“You are such a naughty girl. I love it. How does it feel?”

“Weird. It’s like I can feel the air. Even though there is no wind obviously.” She whispered back and grabbed my hardening cock through my trousers. I inhaled sharply. “When I sit down the fabric of my skirt is pressed against my sensitive skin down there. I don’t want to leave a wet spot on it.” She continued and caressed my cock. All the teasing of the last hours drove me crazy.

“Your cake madame.” Liz quickly let go of my cock and slightly pushed me away when she heard the voice of the waiter. Had he seen that she massaged my cock? I was nervously moving on my chair and waited for him to leave again. When he was gone Liz grinned at me and happily ate her cake. When she finished I paid for it and we both left. All the way back to the car I was carrying an erection in my trousers. I thought about Liz’s panties-less pussy under her skirt. When we arrived in the garage I looked for other people but wasn’t able to spot anyone. As soon as we sat down in the car I leaned over to her and started kissing her. My hand moved under her skirt and touched her bare pussy. My other hand moved under her shirt and touched her breast.

“You naughty little girl.” I said when I realized that she also wasn’t wearing a bra anymore.

“Surprise.” She said and winked at me “I’m a bit disappointed that you didn’t notice it earlier.” She opened my fly and pulled out my cock. I started to moan when she put her thumb on my throbbing dickhead.

“Your perky perfect tits don’t need any support. They stand perfectly.”

She smiled at me and leaned down to take my cock in her mouth. I was so horny I wasn’t even looking for other people anymore.

“This whole trip made me super horny Liz. I don’t know how long I can hold it.” I fondled her breasts which were laying in my hands. She released my cock from her mouth and stroked it really fast with her hand.
