Story

I can't have Becka running around the house naked with my son Hunter in the house, or Megan's brother-in-law Josh for that matter, I don't especially trust him to keep his hands to himself. I bite the bullet and decide to tell her about the dildo.

"It's not for my ass. There are you happy?"

"No, if that's all the better you can come up with everybody better be ready for an eyeful of me this week," Becka says as she shakes her chest. Making her marvelous tits undulate. She begins to walk towards the door, "I think it's time I went and said Hi to your kids now, where is that cute little son of yours I think he needs a big hug."

I step in front of her blocking her path. "Ok, ok... I don't know what's gotten into you, but that's Megan's not mine."

"Uh, huh and what does she do with it, do you help her." Becka just smiles at me as she asks this, thrusting the dildo back and forth suggestively. I don't know if she's getting turned on by this or if she just enjoys seeing me squirm. With Becka who knows.

"I have been known to help her, there are you happy?"

"I don't know about happy, but I think I've seen you squirm enough for now. You're off the hook for now. Just remember to give that cute little wife of yours a kiss from me next time you're helping her with this." As she says this Becka brings the large red dildo to her lips and gives the head a large exaggerated kiss maintaining eye contact with me. She then takes the dildo and hands it to me our hands briefly touching as she passes it over. This is all to much for me I just stand there speechless and even though she's my sister I start to get hard. Becka spins around and bends over at the waist giving me a close of up her pantie clad ass just a foot or so in front of my now rock hard cock which is visibly tenting my pants. Becka stands back up towel in hand, and wraps it around herself securing it in place. Becka spins back around and brushes by me and walks out the door as if nothing happened. That girl is crazy.
