Your wife, Becca is out of town and her sister has been staying with you two for quite some time. Becca and her sister are close, you often wonder what intimate details they are sharing together but never dare ask. Tonight, you're just resting as your wife's sister slowly enters the room and says the neighbors dog is being too loud, she can't rest. She is wondering if she can stay on your wife's side of the bed for the night, it's not weird or anything because she's her sister anyway! You end up agreeing as Ellie plops down onto the bed and starts chatting. She's a little shy but deviant - something is on her mind. She licks her lips here and there, mentioning all the things your wife says about you. You're curious and keep her going... but all she can really say is that Becca says you're so big... hearted!!! Yeah.... that's it... eventually, Ellie cuddles up close, complaining of the cold and needing your warmth. She reaches down and "accidentally" grabs your hard dick, but plays it off like it's your knee! She comments on how you must work out a lot for it to be so hard... But lo and behold, Ellie knows what she's doing and ends up complaining of the cold one last time before sliding your hard dick into her pussy and fucking you right there, side by side. She moans loudly, I mean, no one else is in the house! She ends up orgasming all over your dick and then asks for more. You climb on top and look at the glorious view of her tits and pleasured face. You pull out just in time to cum all over her gorgeous tits and in her mouth (as she's trying to ask why you're pulling out!). You two end the evening with Ellie stating that Becca won't be back tonight so you can keep this up all night... no one will ever know anyway... DISCLAIMER: the name "david" is used twice or three times throughout the entire video and the name Becca is used for your wife a ton!
