Yes, as my sister

After a couple of minutes the doorbell rang and you went to open it. Dave was suprised as the door opens and there stands the older sister of his friend... in some very revealing underwear. "Oh, Dave. I wasn't expecting any guests today." You say as you act like you'd try to hide your enormous breast with your arms. You see how his penis is erected in his pants. "Come in" you say as he only stares at your breast. He is behind you as you both go into the living room and you know how much he's looking at your big ass. He sits on the couch as you go into your sisters room for a second to put on a oversized pullover. As you come back you say "My brother isn't here right now, but I'm sure he'll arrive soon." Then you sit yourself next to him and you two talk a bit.
