My friend Emily and her husband moved to a new place, so I went to visit them. We drank together at night, and since I had driven, I couldn't go back home, so I decided to stay over.
Emily and her husband slept in their bedroom, and I laid out a futon in the living room to sleep.
In the middle of the night, I had a stomachache and went to the bathroom. After about 10 minutes, I came out of the bathroom and bumped into Emily's husband, Mike, who had also woken up to use the bathroom.
"Oh!" I was surprised and quickly said, "Sorry, I was just using the bathroom," and tried to return to the living room. But Mike grabbed my arm and pulled me into the bathroom.
"No, stop!" I resisted. My voice echoed in the bathroom, and I was worried Emily might hear, so I couldn't raise my voice too much.
Mike made me sit on the closed lid of the toilet, pulled down my sweatpants and underwear, and started performing cunnilingus on me. Mike then pulled down his pants and revealed his penis. It was much thicker than my husband's.
He made me perform fellatio on him. The Mike who had been drinking with us earlier seemed like a different person.
"This place is too cramped, let's go to the living room," he said, leading me to the futon in the living room.
I whispered, "Emily is sleeping in the next room... please just use your mouth," but he said, "This is a rare chance to do this with you, so no," and pushed me down.
The small light was on, and I felt embarrassed that my body was visible.
Mike gently said, "I've always wanted to see your body... I've been looking at your chest through your T-shirt," and he caressed my slightly brown nipples.
He massaged my breasts while performing cunnilingus. He skillfully caressed my nipples with his fingers.
He even saw my anus, which my husband had never seen, and licked it intensely. I grabbed his hair and pressed his head against my anus, feeling pleasure.
"I'm doing this with Emily's husband... I'm showing my private parts to someone I shouldn't... but it feels so good..." I thought, and I couldn't help but moan.
At first, I resisted a little, but as I started to feel pleasure, I honestly let go and let Mike do as he pleased.
With my eyes closed, my clothes and underwear were automatically removed, and the next moment, Mike's tongue brought waves of pleasure.
"If it feels this good, I don't care what happens..." I thought, surrendering to the flow.
"Mike, you can do whatever you want with my body... it feels so good," I said.
When we were in the cowgirl position, I noticed the door to Emily and her husband's bedroom was slightly open.
I thought Emily might be listening to us, and the thought of being watched made me even more excited, and I continued to move my hips.
In the missionary position, I was about to climax and said, "Mike, there... it's so big... it feels so good... I want to come... push harder... more than Emily..."
I wrapped my arms around Mike's back and clung to him, climaxing and trembling slightly. Mike took this opportunity to thrust even more.
"You're cuter than Emily... I love you," he said.
I thought Emily might be awake (later I found out she was indeed awake and watching)...
"This is wrong... Mike, you have Emily... I have a boyfriend... doing it raw is bad..."
He pressed against me, biting and licking my ear, whispering, "I love you... I'm going to come... it feels so good... I want to come inside you... because I love you... I'm coming..."
Mike's penis throbbed inside my vagina, and a large amount of hot semen flowed into me, overflowing.
We kissed and hugged for a while, and I felt the warmth of Mike's semen spreading inside me.
In the end, Emily was awake and watching, and it turned into a big mess later.
