Of course not! Have you seen that ass?

Fuck it, you thought. You've already gone this far. You pull Ashley's hand away from your dick and lift her tight little body up onto the bathroom sink. You pull off her shorts, and are inches away from entering her when she stops you.

"Wait! I really don't want to get pregnant right now." She glances down at your cock and then back into your eyes again. She must have sensed your frustration because she offered another idea. "If you want to be more careful, we could try…" Her voice trails off as she pushes you off and turns over. Your eyes are immediately drawn to the glistening of a shiny blue butt plug.

"Help me out?" she asks, looking back over her shoulder with a grin.

"What? You mean… ?" You sputter, trying to wrap your head around this sudden shift in plans. The thought of being inside your wife's sister's ass has you light headed.

"Yep," she says confidently, "Just do me a favor and lube it up a bit first."

You don't need to be told twice. You spit into you hand and begin to spread it around the base of the buttplug and into her tight little hole. You could feel your cock throb with anticipation as you pull the plug out with a pop and toss it into the sink.

"You're fucking killing me, Ashley," you groan, your cock throbbing with need. You spit once more, this time directly on to her ass and push her onto the floor. You line the head of your cock up with her anus and slowly, you push inside her tight ass, eliciting a sharp gasp from both of you.

Her body shudders as you begin to fuck her, each movement sending shocks of pleasure coursing through your body like electricity. It feels so different from any other pussy you've had before, tighter and more forbidden. Your thrusts are slow at first, both of you adjusting to this new feeling.

"Fuck me, Chuck! Fuck my ass!" She moans, the sound echoing off the tiled walls of the bathroom.

You can feel the wetness between her legs, and you know she's enjoying this as much as you are. Your cock slips in and out of her tight hole with ease, each thrust bringing you closer to orgasm.

With every plunge, your thoughts become more hazy, more focused on the intense sensations flooding your body.

"Oh fuck! I'm gonna cum!" You grunt as your orgasm builds to a crescendo.

"Come inside me!" She cries, her voice hoarse from screaming. "Fill my ass up!"

You oblige, thrusting harder and faster until finally, your cock explodes into her tight ass.

As you collapse onto the wet bathroom floor, panting heavily, you can't help but feel a sense of satisfaction. You've just fucked Emma's sister's in the most forbidden place imaginable.

"Well," you said. "You should probably get a shower before Emma gets home. I'll get started on unpacking your stuff."

As the shower starts running and the bathroom fills with steam, your mind is racing with thoughts of what you're going to do when Emma gets home.
