You and your sister have just arrived at your mother's house where you will be spending the weekend. For awhile now, you and your sister have been engaging in a secret affair, unbeknowest to everyone. Not long after the two of you arrive, you and your sister are sitting on the couch. Your mother is busy in the kitchen, and so your sister wants to take the opportunity to sneak away with you and have some fun since your mother should be too busy to notice. She tells you how all she's wanted to do all day is suck your cock. She needs your huge cock in her mouth. She needs to taste your precum. The two of you sneak into one of the bedrooms, where your sister quickly gets down on the ground, takes her shirt off and then takes your big, already hard, dick out of your pants. You have to be quick, you don't want your mother to catch the two of you in this position. But, it is a turn on knowing that she is so close by and can walk in at any time. It's so risky, so naughty, so taboo. Your sister goes to work, sucking your huge cock, taking as much of it into her mouth as she can. She sucks it, licks it, kisses it, slobbers all over it. It feels amazing. When you get close to cumming, your sister tells you that she wants you to cum all over her face. Sure, doing so is extra risky, since your mother could possibly see the cum on her face, but that makes it even hotter. And you really want to see your sister's face coated in your huge load. And that's exactly what you do. You cum and a huge load explodes onto your sister's face, but just as soon as you finish cumming, your mother walks into the room! She is clearly shocked and separates the two of you, telling you that she will be back to talk to you about this later. Later that night, your mother has the talk with you. To your surprise, she's not angry. In fact, it's quite the opposite. What she saw turned her on. Especially seeing just how big your cock is. Nothing turns on mommy quite like a huge cock. Your mommy wants to fuck you. She can't believe that you've been fucking your sister instead of her this entire time. Mommy can pleasure you so much better than your sister can. And she wants to show you that. Your mommy then gets on top of you, your cock already achingly hard from hearing your mommy talking like that and seeing her naked body, and begins to ride your cock. She bounces up and down, pure bliss on her face as she takes your entire big cock inside of her. Mommy wants to cum with you inside of her. She wants to squirt all over your cock. However, she doesn't want you to cum when she does. No, instead, after she cums she wants to go down and suck your cock. She wants to taste her own squirt on your cock and then, she wants to taste your cum as you cum into her mouth and down her throat.
