I've been casually fucking my housemate (slim Chinese girl, who I'll call S) for a while now, and she asked what my fetishes are, initially she was a bit shocked when I said being watched, so I didn't really bring it up again.

A week ago, she knocked on my door and got very handsy right away, uncharacteristically so, normally I do the chasing. She was wearing a tight black dress with stockings underneath, and looked really hot, even for her. We started making it in my doorway, and her hand immediately went to my cock, rubbing me hard through my trousers.

She then pulled me to her room by my cock, when we arrived, I tried to cover myself, because a very innocent looking Korean girl was sitting on her bed. I had completely forgotten our conversation, so asked S, "who is she?" "she wants to watch." "watch what?" S pushed me down on her chair, and started undoing my belt.

As I was being unclothed by S, I studied the girl. She looked young, I'd guess around 20, she was very tiny and looked very innocent, she was wearing a buttoned up blouse, with an oversized blazer, and a black skirt. She wasn't wearing shoes and I noticed her toenails were bright red through her slightly transparent tights. She looked a little confused, and audibly gasped when S took out my already hard cock.

I smiled and asked her "do you like it?" she blushed, looked away, and said "It's very big". I put out my hand for a handshake, she hesitated but shook it, and introduced herself as H. At that moment, S took me into her mouth and I moaned loudly. I grabbed her hand quite tightly as well, and accidently pulled her towards me.

H took my pull as an invite to join S on her knees and look more closely. I told S to slow down a bit, as if she kept going at her own speed, I'd burst. H was still holding my right hand, as I pulled my cock out of S's mouth with my left. I slapped S playfully with my cock as I showed it off to her friend.

"Is it the biggest you've seen?" H blushed and let go of my hand. I caught on and asked: "is it the first one you've seen?" She nodded. S started sucking me off again, and I grabbed her hair and pushed deep. "Are you here for just this, or do you want to see your friend get fucked too?"

She shyly looked away, afraid to answer, I stood up and took my trousers and boxers off, and gave them to her, she folded them and put them on the chair as S licked my balls. I told H to stand up, and turned to her, she was so close to me that my cock poked her, I started rubbing it a bit, deliberately pushing it against her. S stood up and I pulled her towards me. I asked again: "Do you want me to fuck S?" she looked down at my cock, which I'd softly pushed in between the gaps in her blouse, running the head of my dick against her abdomen. H finally nodded, and I playfully pulled her towards me, and said thank you from very close while my cock pushed against her.

I pushed S on the bed, she willingly complied, by diving in and sticking her ass out. Her dress lifted to reveal her red panties, which I swiftly pulled down. H laid down next to us, fully clothed, but her skirt lifted up, even through her tights, I could see a distinct wet spot on her pink panties.

I grabbed S's ass and pushed in deeply, she was soaking already. I fucked her harder and faster, and pushed her down with one hand. H stared into my eyes as S moaned into a pillow. I signaled her to open her blouse a bit, which revealed a matching pink bra.

I could feel S convulsing and my orgasm wasn't far behind. As I started cumming, I pushed my hand into H's blouse, and played with her tits, she looked shocked, but allowed me to go under her bra. I filled S with my seed, as I messaged H's small tits. S pulled herself up and I kissed her neck from behind. I pulled down S's bra and revealed her tits to her friend before I cupped them.

After watching us for a moment, H stood up and thanked us so politely that it bordered on awkward. I smiled to S and kissed her again.

Apparently H has been asking about me a lot and driving S up the wall, I joked to S that she should let me be H's first, but I think she's too jealous for now...
