Warn her

“Jade,” I grunted, pulling my mouth from the tit it was sucking. “I'm about to cum.” She started to lift up, but my hands were on her hips. Before she could object, I said, “You know, it means so much that you would trust me to cum inside you. I can't imagine how rejected I would feel if you didn't take my load.”

“But Ron,” she said, slowing her hips to a near stop, “what about... what about what might happen?”

“Exactly,” I said, pushing up into her to keep myself close to the edge. “That you would trust me that much and be willing to take that risk, it says a lot about how special you think I am. I mean, the fact that you're staying on top and are in control but are choosing to let me fill you, that's just amazing. I feel so cared about.”

It was a risk, but I was pretty sure she was committed to following through. So I released her hips and began feeling her tight ass and bouncing breasts. I was seconds away and Jade was slowly but firmly riding me still.

“Oh, God!” I gasped. Jade looked at my face. I smiled and nodded.

“Oh Jade, it's happening! I'm gonna cum inside you!” Jade looked around, panicked, then seemed to resign herself to what she felt she “owed” me.

Jade nodded. “Do it, Ron,” she urged me in a sexy whisper. “Fill me up. Give me that load. I want it.”

“Oh FUUUUUCK!!” I shouted, pushing up as hard as I could and grabbing Jade's ass to press it closer in just the way I liked. Pump after pump, spray after spray, until my whole load was deep up inside her, where no man had ever been (or would ever again be, I imagined). When I was done inseminating my lesbian friend, I collapsed back onto the bed and dropped my arms to my sides.

Jade leaned to the left and pulled her pussy off my still tingling cock. She looked down in disbelief at what had happened. Then she rushed to the bathroom to clean up. Sometime later, she was back in my room, putting her clothes on.

“I guess I can go get a morning after pill,” she mused aloud as she put on her panties. “Never thought I'd need to say that.”

“Wait,” I sat up, feigning concern. “You would... you're so turned off by what we did that... you would...?

“What? Oh shit! No! I didn't mean that. I just... I mean, of course I won't do that.”

I visibly relaxed. “You promise you won't?”

“I promise,” she sighed.

“Jade, you always keep your promise. OK?”

“OK,” she said, rolling her eyes. But that was a command, and she would have to obey it.

“So... was this helpful?” she asked as she strapped her bra and adjusted the straps.

Still naked, but satisfied and under the covers, I had my hands folded behind my head, leering at my conquest. “Very helpful, Jade, thank you so much. I think you really got me over that hang-up.”

“So are you ready to go back out there and find a woman to be with?”

I thought about the app and all the potential it had.

“I sure am.”
