The time my girlfriend fingered me [MF]

My girlfriend and I have always had a pretty standard sex life. Both living at home makes it a little hard to be too adventurous and limits our opportunities. We do however try to do what we can.
As standard as it was things took an exciting turn. We had been at a party and both gotten into a fair amount t of alcohol. It was no surprise when we got back home and both instantly took off everything. Before I could lie in bed she was reaching for my dick. She slowly stroked it as we kissed and reached lower to massage my balls (which she knows I love). To my surprise as we made out she tried to reach a little lower. I rolled her onto her back and quickly went to town. She was freshly shaved like she was waiting for it and I began to lick and suck on her clit. After making her cum she insisted she got on top.
She bounced and grinded on my rock hard cock and I reached up and pinched her already hard nipples. She can’t resist when I suck and pull on them. She rode harder than she ever had as we both moaned along, pushing myself as deep inside her as I could while she placed her hands on my chest and I admired her perky breasts bouncing with her hip movements. What happened however I never saw coming.
I begged her to tell me what she wanted next and between moans she managed to say she wanted to finger my ass. My heart jumped, I always imagined being dominated in some way, but never told her. Our sex was always good, but standard.
“You wanna finger my ass” I asked as she continued to ride her eyes rolling back. She nodded “yeah I want to finger your ass”.
We busted out lube and I rolled over. It felt cold but nice as she rubbed the lube against my hole. Without warning she slid her finger inside me and I wasn’t prepared for how great it felt. I tightened up and asked for more lube and she obliged putting a generous amount on my hole and her finger. Again she slid it inside me and I got up higher on my knees to give her easier access.
She was sliding it deeper and deeper but not too hard and I begged her to tell me what she was doing as she did it. “You like that babe? That’s one finger” and then I felt another push “that’s two”. When she could tell I was comfortable she pushed harder in and slid out eventually she was fucking my ass with her fingers almost as hard as I can fuck her. I moaned louder and louder and she reminded me to keep it down. She reached with her other hand and stroked me while I would back into her fingers.
Eventually I couldn’t take it anymore I was going to burst. “You gunna cum?” She asked like she could read my mind. I couldn’t speak with how hard I was moaning and she took her fingers out of my ass and took my place on hands and knees.
Before I could get more than three strokes in I busted the biggest load I had ever had all over her ass and collapsed on top of her.
“Fuck that was so hot” she claimed. And I could only nod.
“I can’t wait to do that again” she said as I pulled her close, “next time I’m bringing a toy”.
