"It's the pizza," I said, my heart hammering. I got up and paid for it and put it on the kitchen counter. Mia grabbed us a couple of plates and a couple of cans of soda. Once we were situated, we resumed the movie. I couldn't stop replaying what had just almost happened. We had been so close to kissing, but then we had to get interrupted.
We ate the pizza in near silence as we watched the movie. If it wasn't for how much it made Mia laugh, I would have thought something was wrong. she had to have known we were about to kiss, yet she didn't seem disturbed at all by it. The sexual tension seemed to have disappeared. I wondered if there was anything I could do to trigger it again. I wanted to do something to seduce her, but I decided against it. The moment, if it had really been one, had passed. Mia must have just been swept up in the moment, and I would be stupid to try and start something again. I resolved not to let my lust for my little sister get the better of me and that I would be better.
We finished eating and, after cleaning up, settled down to finish watching the movie. Mia pulled the blanket over us and lay against me again. I had hoped both that she wouldn't do this again but also that she would. I held her, trying my best to act natural. It didn't take long for me to start to get hard. I shifted slightly and tried to readjust the blanket to cover up my erection, hoping that I wasn't too obvious as I did it. Mia didn't seem to notice.
The movie ended. "So, what do you want to watch-" said Mia as she reached across me to grab the remote. As she did, her arm brushed across my erection, making her stop midsentence. The contact felt so good, but I was mortified. "Oh," she said, frozen with her arm still near where she touched me.
"I'm sorry. I'm just going to go to my room," I said as I stood up.
Mia grabbed my arm, "Don't go. It's ok," and then she added softly, "I don't want to be alone right now."
She looked so vulnerable. Even though most of my brain was screaming at me to leave before things got even more embarrassing, I realized that she needed me. I couldn't leave her. I sat back down, and Mia smiled.
Mia cuddled back against me. I held her and rubbed her back, trying my best to comfort her. After a few minutes, she finally broke the silence. "So, you must have really liked that movie."
"Shut up," I said and playfully shoved her. Even when I was comforting her, she just had to go and tease me.
"If you want, we can watch it again," Mia shoved me again, "Or if maybe it was the lead actress that did it for you, we could watch another movie with her in it," Mia said as she reached for the remote. I snatched it up before she could grab it.
"Shut up," I said.
"Give it to me." Our shoving intensified, and we got into a wrestling match on the couch. This was something that we had been doing since we were kids. While puberty had given me an advantage with my growth spurt, it had also given Mia an advantage when she began to develop her beautiful body. I usually tried to avoid touching her in any inappropriate areas, but that night she seemed ferocious as she fought to take the remote from me. Mia jumped against me. I tried to push her back, my hand pressing against one of her breasts. I felt her nipple harden under my touch. I didn't get a good grip, and she fell against me. Her tits pressed against my chest. As Mia tried to take the remote from me, she kept on accidentally brushing against my dick. A thrill radiated through my body with each touch. It happened so frequently that I started to suspect that it was intentional.
I managed to grab hold of one of her wrists. She tried reaching between me and the couch to get the remote. I tucked the remote between the couch cushions and then wrapped my other arm around her waist. Mia strained to get past me. We got tangled up in the blankets and rolled off the couch, with Mia landing on top of me. I was intensely aware of how her body was pressing right against my erection. We held eye contact as both of us were panting from the exertion. Our gaze lingered. She parted her lips. I was torn, I wanted her so badly, but I also wanted to do what was right.
Suddenly something just clicked between us. Mia started to lean down, and I sat up to meet her kiss. It happened so fast. One moment I was torn between my responsibility and desire, and then her delicate lips were pressed against mine. Her full lips pressed against mine felt so amazing after so long spent fantasizing about them. The kiss was deep and sensual, our mouths opening as our kiss deepened. It was the best kiss of my life.
Mia started to grind herself against my erection so I began to rub press back against her. She moaned into our kiss. I ran my hands from her back down. When I grasped her ass, she moaned. I massaged her ass, savoring finally being able to touch it.
I slid my hands up from her ass and gripped her hips to better control what we were doing. Mia's breathing got more ragged the longer we dry humped. I could feel her warmth and wetness seeping through her panties and shorts. Mia started to bite and suck on my lip. When I went back to her, she moaned into our kiss.
Mia began to grind even harder against me. Each time our bodies pressed against each other, Mia let out a little moan, and her face contorted in pleasure. When she would sit up to ride me at a different angle, I couldn't take my eyes off her bouncing tits. Mia grabbed my hands and pulled them up to her breasts, pressing my hands into them. She moaned as I kneaded her breasts, savoring their softness and the heft to them. I played with her hard nipples through the soft material of her shirt.
Mia's breathing got louder, and she started riding me even harder. I could feel myself starting to get close to cumming. Mia was riding me perfectly to press along my entire length, and then when she reached my head, she would gyrate against me. She pressed down onto my chest to balance herself as she rode my cock.
I slipped my hands underneath the hem of her shirt and touched her breasts directly. They felt better than I could ever imagine. I rolled one of her nipples between my thumb and forefinger and then gently pulled on them.
"Harder," Mia said. I didn't know if she meant her nipples or humping her, so I did both. That must have been the right decision because Mia cried out, "Yes."
"Oh, Andrew," Mia moaned. She stretched up as her orgasm rocked her body, and she kept on calling out my name. At the sound of her moaning my name, I couldn't hold back any longer. I cried out Mia's name as I came. I felt my loads shooting up against my boxers and coating my cock. I couldn't remember the last time I had come so hard and couldn't believe it had come from dry humping. I had never been able to cum from that before.
Mia collapsed down on top of me when she was done cumming. I slipped my hands out from under her shirt and wrapped my arms around her. We lay like that for a while as we recovered. At first, there was just the sound of us breathing heavily. Eventually, our breathing evened out, and we lay together in silence. My mind was racing as it processed what just happened between us and how it could change our relationship. Overall, I felt good about what had just happened. I couldn't believe that one of my most reoccurring fantasies had just come true. I knew what we did was wrong, but it had felt so right, and Mia had been the one who had initiated things between us. That fact helped me feel better about what just happened. She wouldn't have done that if she didn't want it to happen too.
I didn't know how long we would lay on the floor like that, but I was in no rush to cut the embrace short. It had been so long since I had been with someone, I was savoring every moment of it.
Mia raised her head from my chest and looked down at me. She looked so beautiful. The sadness was completely gone from her beautiful brown eyes. Her mouth opened like she was about to say something, but then she closed it again. A moment later, she said, "Thank you for always being there for me. I really needed you tonight."
"Of course, Mia. Anytime you need me, I will always be here for you."
Mia smiled and then leaned down to kiss me. The kiss was sensual and sweet, filled with more intimacy than I had ever had in a kiss with anyone else. I could feel my cock starting to stir from the intensity of it, but she broke the kiss before I could get too turned on. She climbed off me and sat back down on the couch. She patted the spot next to her. I picked the blanket up and sat back in my spot. Mia snuggled up against me, clinging even tighter to my side than before. I retrieved the remote from between the couch cushions and browsed Netflix for a movie to watch. I wasn't focusing too hard on finding a movie because I was still processing what had just happened between us.
