Chill with her on the couch

You both eat in silence, lost in thought while you try and **** down this salad and get it over with. When you finish you both sit in companionable silence and scroll on your phones for a bit. It feels good to just hang with your sister again. Now that the weirdness of your new ownership is dying down. You eventually get bored and get up deciding to go see if any new shows are on.

After a bit of scrolling through lists Theresa follows you into the living room and snuggles into your side before quietly resuming playing on her phone. You smile and drape your arm over her and give her a squeeze. Theresa reaches up and moves your hand from her arm onto her breast before squeezing your hand into her boob and then going back to her phone. With a mental shrug you give it a few squeezes and hear Theresa make some pleased coos.

You eventually pick some new buddy cop show and let your brain drift as you enjoy the series. You while away most of the day binging the first season, but you are starting to get thirsty. You tweak Theresa's nipple through her shirt and she yelps and looks up at you. "Hey sis... You will do anything I ask right?" you ask her in a husky voice as you slowly lean in for a kiss. Theresa lets out a moan as she says "Oh yes master, anything at all." you lean in until your lips are almost touching and whisper "Could you get me a drink?"

Theresa snorts and glares at you as she gets up "Ugh, fine bubby. I will use the gorgeous and fuckable body you own to get you a drink." You admire her bare ass as she leaves. You started up the second season and are a bit surprised when the sexual tension between the two main actor and actress turns into a whole softcore porn scene. The main actress is very attractive and the show has a lot more sideboob than you were expecting as it has moved onto an infiltrating a strip club storyline. You have to adjust yourself as your erection emerges.

Theresa walks back in holding a glass that is gently fizzing something or other and whistles at what's on the screen. "Oh man, you got the party started without me." She hands you the drink before turning around and sitting down directly on your lap. Reaching behind herself she grabs your free arm and presses it back into her boob. You sigh but don't tell her to move as you take sips of your drink and watch the surprisingly scandalous show from over her shoulder.

After a minute Theresa begins to slowly grind against you and you sigh as you feel a faint dampness spreading from her bare pussy. The main actress in the show is currently wearing some skimpy underwear while in a chase scene and you cant take it anymore. "Get up." Theresa gives you a pouty look over her shoulder but stands up. You quickly undo and pull down your pants to mid thigh, freeing your painfully erect member and grab Theresa before she sits back down next to you. You guide her back onto your lap and Theresa lets out a happy squeal as you pull her onto you. She moans as she settles into your lap again and you start to grope her breasts.

You settle in to a slow rhythm of Theresa stroking your with slow undulations of her hips. In the show the bad guys have captured the hero and have her chained up with her already skimpy outfit even more torn up. The villain brandishes a baseball bat and strikes the hero in the stomach making her spit out a hairpin with enough **** to stab the baddy through the eye. Theresa leans back while you scoff at the ridiculousness of the scene and whispers in your ear. "Oh, looking for ideas for later? You still haven't tried anything like that yet."

You give her a horrified look before she giggles (which feels amazing on your dick) and says "I know you would never do that to me master, even if you can." She leans forward again to get more leverage and starts to bounce on your lap. She moans as she feels you twitching inside her, which given how much teasing has been going on doesn't last long before you Grab her hips and pin her to you as you release your cum deep inside her.
