Leave club & have sex with woman in front of b

I’m out the other evening. I go home with a young lady. We get to her house. She says she lives with her brother before we get inside. I think nothing of it, we get inside. He’s watching tv in the living room. We stumble to the couch. She tells him to “get lost.” He disagrees. She says whatever. She starts making out with me undoing my shirt. She undoes my belt buckle. Unbuttons my pants unzipped them & pulls my hard cock out. She taunts him saying “You see this. This is a Man!” One hand lightly stroking the other cupping both balls. She looks up at me gives me a kiss & begins to give me one of the most amazing blow jobs of my life. I look over at beta boy brother looking from the corner as big sis try’s fitting a big cock into her mouth. He’s watching from the corner of his eye. Slightly turned on. I just say “you like this” he begins to blush as me make eye contact,. “Of course he does” she explains. “Who doesn’t” as she stroked my cock slobbery with saliva using both hands.
I could tell he was horny. It was time I fuck this guys older sister. I knew he wanted to stay & watch..
Part 2 soon
