Big Sister 1.0

This is a simple dialogue where a teenage boy ties up his older sister and forces her into a blowjob.

The sister is not happy about this. She is assumed to have her hands tied and should be in the angry or disgusted moods.

Dialogue is a bit more lighthearted (as lighthearted as you can get when it comes to non-consensual incestuous fellatio) and involves the sister hurling lots of insults at you.
