You decide to leave. But leaving right on the spot would be rude right?
You cannot ruin your sister's... no your relationship? Wait? Is it "your" relationship? You never consented to, right? But you adopted your sister's body, does it mean you adopt her relationships as well? Are you his girlfriend?

Whatever the case might be, you decide to wait for a good moment to leave. You sit down on your boyfriend's couch and ensure that you keep your knees together, you do not want him to get any wrong ideas. Thinking about having him going down on you or even having you inside gives you the shivers.
