Bracing my hands on his chest I guide my friend's dick into me. He wakes up pretty quickly as our hips meet and I frown at his look of discomfort.
"What the fuck Jack?!" He groans beneath me as I work.
"This is what you wanted when you slipped me that xchange isn't it? You wanted to fuck me right? Well now I'm horny and you're hardso sit back and behave like a good boy until I'm done."
"Wait, Jack if I cum inside then it's permanent, you'll probably get pregnant!"
I can't help but roll my eyes at him as I set up a rythm, rocking my hips forward. "Then pull out before you cum, doufus."
I pause as his hips spasm beneath me, his dick pulsing inside me as he groans. My face heats up in embarrassment as I slowly realize what has happened. I look down to see the mess we made as pins and needles tingle on my skin. I'm stuck.
"Too late."
