First foot job from GF!

I’ve been with this girl for a while and, and recently I told her about a different fetish a have which we explored a little. She’s also opened up to me about a mild bondage fetish she has too which I think is pretty hot.
Anyways, it’s been a while since we’ve gotten together since we’re both full time collage students with jobs who are nearing our finals. But last night we were able to get together at my apartment, enjoy some takeout, and have a nice stay in date.
The good part comes when we’re sitting together on her couch watching a movie we rented off amazon. We’re sitting so that our bodies are facing each other and her feet happen to be on my lap. I tried not no notice at first since she didn’t seem to think anything of it and we were still watching our movie. Then she starts to move a little, says something about her feet being cold and grabs a blanket from the floor. When she threw it over us, she started rubbing her bare feet together to warm them up. Her feet which are right in my crotch, are basically rubbing my dick. I’m pretty sure she knew what she was doing, but she may not have.
I start to get really hard, and it’s impossible to hide now since her feet are on my lap and I’m wearing PJ pants. As my dick rises, she glances at me and I look back at her to see she’s trying not to laugh. I was embarrassed for a second until she says “Sorry, I didn’t know my feet could do that.” We laughed a little, then she turned back to the movie. I did too, while thinking of ways I could take this forward without being pushy, then she did it for me. While we’re watching, she starts to rub my dick with her cold feet under the blanket. I started to get super excited as this is the second major fetish of mine that’s coming true with her, so naturally my dick gets harder. She starts to do this thing where she squeezes it between her feet and I can’t describe how good it felt.
Neither of us were really paying attention to the movie anymore. We’re locked eyes as she pulls my PJ pants down just enough for my dick to spring out, and she starts playing with my dick as well as some light taps to my balls. I ended up finishing on her feet and after I caught my breath I look at her and smile back. “Did I do good?” Yes Hun, clearly you did good.
I don’t want this story to get too long, but after clean up I was ready for round 2 and was able to “reciprocate”. I love this woman.
