Fuck them both at the same time.

"Since I don't have much time left in my lunch hour, how about I fuck both of you at the same time?" I suggested with a grin.

"Unless you will suddenly sprout a second penis I don't know how you're going to do that," Catherine wondered.

"Oh, believe me he can," Susan giggled, giving me a sly look. "Do you want to be top or bottom, Cat?"

"What do you mean?" the blonde asked.

"Just lie down on the bed with your butt on the edge," I recommended.

Catherine wasn't sure what I had in mind but nonetheless she did what I asked and instinctively spread her thighs apart for me.

"Wait, what are you doing, Sue?" Catherine gasped when the Chinese beauty laid on top of her. "I'm not a lesbian!"

"Well, I'm not straight either but we're both here in a cheap motel room trying to get knocked up by our friend's husband!" Susan replied before giving her friend a kiss. Catherine resisted at first but she had already succumbed to the smell of lust in the room and kissed back.

Standing between their outspread legs, my already rock-hard cock just got harder at the sight of the two gorgeous women kissing and their wet pussies beckoning me. I rested my hands on Susan's thighs while I positioned my cock towards Catherine's slit.

"MMffph!" the blonde moaned in her friend's mouth after I jammed the full length of my thick shaft into her cunt in one quick stroke. I guess she was all worked up from her first lesbian tryst that it didn't take her long to climax. As much as I would have loved to keep pounding away at her pussy, I still needed to fuck Susan -- to try to make a baby, of course!

I unceremoniously pulled out of Catherine's spasming pussy and shoved it into Susan's tight cunt. I pounded her from behind until she came and I switched back to Catherine. I kept going between the two women, bringing them to orgasms, until I had to cum myself.

Normally I would just keep thrusting until I emptied my balls but this time I had to pace myself. When I felt my balls tighten, I choked my shaft so I could control how much semen I would ejaculate into Susan before I would quickly slip my cock into Catherine's pussy and empty my balls into her fertile womb.

"Oh my God!" Catherine gasped. "Are all of your lunches like this?"

"Yes," I grinned, pushing myself off the girls.

Susan rolled off of Catherine and looked over at the clock on the night table. "It looks like we will barely have enough time to take a quick shower before we have to get back to work," she sighed.

"Actually, I told my manager that I was meeting up with Sam for her ultrasound at lunchtime and he told me to take my time," I replied.

"So we have plenty of time to get you hard again for round three?" Catherine purred.
