Jeff thought to himself....
“I’m stuck like this... an immortal being used for nothing but sex... this is both awesome and a hell... I can’t control anything except when someone attaches me.
Oh well I can live with this....”
The bedroom door opened again...
“Time to get my fuck on!” He thought
Sarah and Amy walked in together, both naked.
"Hi Jeff, Sarah and I are going to have some fun and we need you" Amy said as she picked him up and carried him between her legs. Understanding what she wanted, Jeff attached to her.
Amy fucks Sarah and, after cumming a few times, Sarah catches Jeff saying it's her turn. Then he dettached himself from Amy and attached himself to Sarah, who used him to fuck Amy.
Sarah kept fucking Amy until their mom called saying that breakfast was ready, and they went down to the kitchen after Sarah came one last time.
Nobody bothered to get dressed before going to eat, including his mother who was still naked, Sarah, who was still had Jeff between her legs.
Even though he did not require any nutrition while attached to someone he could get nutrition anyway which grew him even stronger.
He was always hard and never went soft.
Which means he could give sex to as many women as he wanted without ever getting tired.
Since it was Saturday, the sisters were off, so they went to their room, where Sarah detached Jeff from her before putting him in her handbag. Then they got dressed and left.
