Breakfast in bed

From Torg Adventure

You get to Kristen's house and the door sports a sign that reads, "Lock the door and come up stairs". {LAST_NAME} looks at you and winks. You step in and lock the door behind you.

You walk upstairs. You are familiar with the layout from the night before. On the wall in the hallway, another sign reads, "Take off clothes and leave here". You both take off your shoes. You pull off your sister's shirt; she's not wearing a bra. She gets your shirt and strokes your tight abs. You each drop your jeans. Your sister has no panties on. You leave everything in a pile. She kisses you and fondles your cock to hardness.

"This seems fun," you say. She nods with a conspiratorial smirk.
