I could feel my orgasm building, pressure in my balls as I thrust into her pussy. She squirmed below me, eyes closed, tossing her head back and forth, her red hair splayed out across her pillow. She was breathing heavily and grunting each time I pushed into her. She held her chest, alternately pulling on her nipples and squeezing her tits together. There were low, animalistic noises deep in her throat as I fucked her.
Any second now, I knew I was going to cum, and I knew I needed to pull out. I wasn't wearing a condom, and she told me she wasn't on birth control. She had asked me to pull out and cum on her breasts, but the idea of removing my cock from her warm, wet cunt seemed inconceivable. It would feel so good to cum inside.
I imagined, for a moment, how she would react if I didn't pull out.
Perhaps she wouldn't notice right away. Wrapped up in her building climax, I think she would only realize what happened as I slowed down after I finished. When I removed my cock, she would feel the hot spunk dripping out of her.
"Did you just cum inside me?" she would ask, confused, and irritated. "I told you not to!" Her voice would grow increasingly frantic as she pushed fingers inside herself. Disbelief and outrage would grow as she felt my sticky cream between her lips. She would try to pull my cum out but only succeed at pushing it deeper. "What's wrong with you?"
But no. More likely she would notice immediately. When my pace changed, and she felt my cock twitching inside her. Even if I tried to control myself, to not make it obvious, wouldn't she feel the heat from my cum?
"What the fuck are you doing?" she would yell, trying to push me away. But I would be pinning her down with my body weight, and she wouldn't be able to get the leverage to move me. I would grunt with effort, unable to conceal my orgasm, desperately trying to keep my cock shoved deep inside her. I imagine the walls of her pussy gripping me tightly as her anger causes her to clamp down inadvertently. She would scream at me, "Asshole!" and wriggle out from under me as soon as I relax my grip. I can picture her cursing at me as she stomps into the bathroom.
I can't deny the thought turns me on, but I don't like the idea of upsetting her. Perhaps it would turn her on? I imagine her being so wrapped up in her rising pleasure that she can't or doesn't want to stop me. I imagine her reaction as she realizes I'm about to cum and I'm not pulling out. She would protest weakly, "No... wait... don't cum inside... oh god... don't cum in me... oh fuck... oh that feels good." Her legs would be wrapped around my waist, pulling me deeper even as she half-heartedly objected.
