Isabella invites her brother to visit her

Isabella invites her brother to visit her the next time Jacob goes out of town for work for a weekend.

The brother and sister haven’t seen each other much in recent years, so he’s happy to accept her invitation. He tells her it’s a good opportunity to get away from his two young kids (“and the wife”, he adds jokingly).

Isabella and her brother have a normal first day. They catch up, talk about their family - nothing comes up to suggest their sexual past. Even when Isabella calls her brother Uncle Daddy, it doesn’t immediately call to mind their summer of fucking. It might have been an amazing and meaningful experience - but as siblings, they have entire lifetimes of experiences.

The second night of Isabella’s brother’s visit they go out to a bar with you and Emma. Isabella drinks heavily and her brother (who’s used to his married with kids lifestyle) struggles to keep up.

Eventually the drinking moves from the bar back to Isabella’s place. You’re all pretty drunk, but you know that the girls aren’t nearly as drunk as they are pretending to be.

There’s a lot of sexual tension building as you, Emma, and Isabella anticipate what will come next.

You and Emma begin making out on the couch near where Isabella and her brother are sitting. He watches the scene as your girlfriend crawls on top of you and your hands explore each other’s bodies. You’re not shy about squeezing her ass and massaging her breasts.

“They should probably get a room,” Isabella’s brother says to his sister, trying to make a joke to help with his awkwardness.

“No, I don’t think so. I think it’s hot,” Isabella says. She can see a bulge in her brother’s pants that indicates that he agrees.

Isabella’s brother watches closely as you unbutton Emma’s shirt. You peel if off and then adroitly remove Emma’s bra. His cock wants to burst through his pants, but he’s too nervous to even adjust himself sitting so closely to his sister.
