No! I should respect my girlfriend

I stopped my hand. My cock twitched a little, but I let the water from the shower wash my arousal away.

It had been a hard day, and I needed some relief. But I was not going to have sex with Sarah, and touching myself while her girlfriend is in the apartment with us felt... wrong. Sure, I was dying to see Sarah naked, and to touch her, but not with Zoe there. Besides, Zoe had beaten me to it. She had both seen my girlfriend naked first, and she had touched her ass first. And now she was also lying in bed with her. I mean, they weren't doing anything wrong, just sleeping in the same bed like the girlfriends they were. But it still made me a little frustrated.

Suddenly, I pictured them naked on our bed, rubbing their sexy bodies together. I imagined Zoe's small, delicate hands massaging Sarah's boobs, caressing them gently, fondling them lovingly. I imagined Zoe playing with Sarah's perfect ass, spreading it, slapping it. They had been so friendly with each other that my mind couldn't avoid thinking of them... Together.

But I stopped my imagination before my erection got any harder. I had to convince myself I was not getting aroused at the idea of my girlfriend being in bed with another girl. No, I got aroused because I'd been seeing the bodies of two sexy women.

Right?
