We finally made love!

We kissed. We kissed for a long time, and our clothes slowly disappeared from our bodies. She made me lie on the bed, and there she was: my girlfriend, Sarah, naked in front of me. I could have died of joy: her huge breasts, fully visible, soft to the touch, spilling on her torso like big balloons with little pink nipples. Her belly was wonderfully flat and firm, and her hips framed a shaven crotch.

"You are gorgeous." I said, almost out of breath. "I can't believe we're about to do it."

"After all this time." She said with a smile.

She grabbed her own breasts, but, suddenly, I imagined it wasn't her, but Zoe, groping my girlfriend. I remembered how that girl had already seen Zoe naked. She has touched Sarah, and had been touched by her. She had kissed her so much. But I shook my head. This touch was different! Much more intimate! Besides, it's not like they have slept together, right? No, I mean, they haven't had sex. That's what I meant.

She leaned forward, making her bosom drop lovingly and jiggle as she reached for my cock. She started stroking very slowly.

"It's a nice dick. How long is it? Four inches?"

"Woah, no, it's... It's five inches!" I found myself stuttering a little. Yes, I had measured myself, of course, and my cock barely reached the 5' mark. I could barely think straight, as the pleasure was immense.

Then she sucked it slowly.

"Oh, Sarah! You're so good!" My cock fully went into her mouth easily, and she sucked it like an expert.

"We're barely getting to the real thing..." She said after a while. She went to her purse and took out a condom. "I was keeping this with me because I knew we'd do it soon. This is the night."

"Wait, a condom?"

"Liam, I don't wanna get pregnant..." She said while shrugging.

"I... Sure. Yes. We'll talk about that later."

She opened the package and gently slid the condom on my hard cock. Then, she got on top of me. I was incredible sight. She lowered her hips slowly, grabbing my dick with high precision so it aligned with her pussy. Then she lowered herself painfully slowly.

I felt a huge surge of ecstasy going through my body. I tried to concentrate on other things so as not to reach climax soon. But my mind betrayed me, and what came to my mind was Zoe: I conjured an image of Sarah sitting on Zoe's face, and Zoe was eating her pussy in the most intense manner.

"Oh, Liam, it feels so good!" In hindsight, Sarah's voice sounded a little unenthusiastic, but at the moment I was too focused on myself to notice.

"Oh... Oh, Sarah!! Sarah!! I'm... I'm...!!"

I couldn't hold it any longer. I had a huge orgasm inside my girlfriend (well, inside the condom). She moaned loudly at the same time as I did, although, once again, it sounded a little... fake? I didn't mind, and when she got off me, I was breathing heavily already.

"That was so good, baby" she said simply. "I love you so much." She took my condom off. My cock was already soft, and there were some drops of semen in the condom. I think I saw Sarah giggle a bit? Maybe. I knew I hadn't lasted long, but I was too happy to notice anything. I had just fucked the most perfect girl ever, and I was going to marry her.

"I'll go throw this away." She said as she tied the condom and gave me a little kiss. Then she left the room.
