First intercourse with a man

He got up and stood next to me, hehe my cum still clinging to his chest and stomach. He used his fingers to collect my cum and with his other hand he spun me so I was facing away from him, he took my cum and slid it into my gaping hole. He grabbed was left from his stomach then slid cum into my ass for lube. I never thought about using cum for lube, but i was ok. I positioned myself with my hands on the desk, bracing myself. He got behind me, and worked his fingers in and out of my wet hole. I began to relax. About that time, he grabbed some paper towels and I'm guessing he was wiping off his hands and fingers. I then felt the head of his cock start to enter me, and to my pleasant surprise, it slid in pretty easy. He had both hands on my hips now, cock buried deep in my ass. I felt good, as he was a bit bigger than me, I was a little on my tip toes as he began his cock thrusting. It started to feel real good. I felt myself getting hard again, and saw i was dripping some cum without even touching. He just keep fucking me faster and harder and what must have been 20-30 mins. Then he moaned loudly and came hard. Hard enough and long enough that i felt his cock twitching good. We stayed like that for about 2 mins, cuz i felt his cock twitch hard, then twitch less and less. It felt warm and wet. And when he pulled out of my ass, i could see why it felt warm, wet, and why it was so intense. He had taken his condom off when he was behind me.

I’m like, “where is the condom?” “is it inside me?, omg what am i ...how am i going to get it out?” i was freaking out.
He said, “relax, it's not inside of you. I came in the condom when you were on top of me, so it was spent, and i didn’t have another condom”
I’m thinking, what? If you came and i came, why did he fuck me again?

I said, “why did you cum in me then? What am i going to do”
He said, “I like to cum twice because i cum fast the first time, and afterwords i can take my time and fuck for hours” “i basically came when you started moving up and down my cock, i didn’t say anything because i didn’t want to ruin what you were feeling, and you came somewhat quick too”
