Go in with Kristen and your sister
From Torg Adventure
The chance to have Kristen more is too tempting to you. You might be able to give her full load of cum too. And your sister is passed out and not going anywhere. She can wait.
"Help me get her inside," you say before you climb out and pull {LAST_NAME} from the backseat. Kristen gets on the other side of her best friend and helps you get her in the door. You make it to the couch and dump your sister into the couch unceremoniously on her side, in case she throws up in her sleep.
Then Kristen grabs your hand and runs upstairs, pulling you along behind her. She goes into a room you can tell is hers and pushes you down on the bed.
"Stay here and get undressed. I'll be right back." She leaves the room.
You take off your shoes, shirt, and pants. As you're dropping your boxers to the floor and pulling your socks off, Kristen comes back in waving a condom at you.
"Now you don't have to pull out!" Kristen says with lust in her eyes.
You try not to let the disappointment show on your face.
What do you do?
