I get to fuck my beautiful sister, of course I'm going through with this!

"I'm gonna have a shower mom!!" I yell to mom as I close Alexis's room door, trying to make as little noise as possible, luckily, the shower room is very quiet when the shower is on, so she wouldn't notice if I was in there or not, as long as the doors closed I'll be fine. I turn around to see Alexis down on her knees staring up at me with wide blue puppy dog eyes, I'm already going off the edge, she really knows how to get a man going!

I walk over to her, pulling off my boxers on the way, and throwing them onto her bed, now my cock is fully erect, a seven inch dick pointing straight at her mouth.

She starts to stroke it, precum pouring out slowly, she licks the shaft from my balls to the tip, then takes the tip in her mouth, then all of a sudden she deepthroats, the whole length, something this good should be illegal!

I take hold of the back of her head, guiding her mouth precisely, I can feel the back of her throat every time she thrusts her head, I moan loud, not caring if Mom can hear me. I can hear her muffled moans as she fingers her pussy, still going hard on my cock.
