I can still remember the night I got the call.
My sister was in town, she was crying on the phone because her fiancΓ© had just left her for a woman he had met on some 'retreat'. After crying for several hours she said she was going to be staying some local hotel to which I told her no way. She would come and stay with her big brother.
Although only 27 and moderately paid my house is nice, I bought as a steal from a couple going through divorce who just wanted to get rid of their 'party' house and split the cash. The house has a bar with game room (they included the pool table, and I keep the bar stocked). There are three bedrooms, massive master bedroom bathroom... more than enough room for a bachelor, but great for parties.
Another fifteen minutes later my sister is at the door and collapsing in my arms in tears. She's very slight, 5'4 weighing 105 pounds at most, so I easily picked her up and carried her to one of my spare bedrooms.
I let her cry herself out on my shoulder and then I told her to get some sleep.
The next morning, in fact the next five days she barely said a word, just moped from the bedroom to the bathroom, eating what I gave her, and crying in privacy till she fell asleep.
I let her, figuring she'd snap out of the depression herself, and sure enough day six she seemed more herself.
That evening's dinner she prepared along with some wine she chose from my bar. After the first bottle she continued having drinks until she was quite drunk.
She verbally abused her ex, describing horrid tortures she'd wish he'd suffer for over an hour before she noticed that wasn't paying that much attention.
"I'm sorry!" she said sounding overly apologetic. " I'm boring you, I'm such a stupid boring bitch!"
"No you are not, you are drunk, and angry, and you have every right to be." I said reasonable from the couch in the bar area.
"I drove him away by being such a self involved bitch." She said bitterly and angrily.
"I doubt it, he's just screwed up in the head."
"You think so? Maybe I wasn't pretty enough."
"Not likely." I responded with a snort of derision. Blonde, athletic and thin, impish face, blue eyes, B sized breasts and small round ass, what guy wouldn't find that pretty enough?
"Oh yeah? You think your little sister is hot?" She asked as she began a drunken stumbly sultry walk in my direction.
"You're my sister." I stated. " But other than that, any guy would be lucky to have you."
My sister got to the couch and collapsed against me, sliding her body along mine that forced my cock to respond instinctively. Of course my sister placed her hand against it to up right herself.
"I don't think it matters that I'm your sister." She said with a devilish grin as she began to stoke my hard-on through my pants.
"Don't do that!" I said as I pushed her hand off.
"Why not? You liked it." She stated.
"You are my sister." I said firmly, " Cum'mon, time for bed."
"Cum on what?" She asked coyly, " Got do more than that to make your little sister cum."
"That is not what I meant and you know it." I said now almost angry in frustration.
"Don't be mad at me." She said suddenly giving me puppy eyes. " I'll be good."
"I'm not mad, here put your arms around my neck so I can carry you upstairs to bed."
