Afraid her wealthy boyfriend is about to dump her, my adult stepsister becomes desperate to secure the marriage she wants. She proposes having sex with me, her adult stepbrother, so she can get pregnant and use it to arrange a shotgun wedding. At first, the beautiful stepsister only wants proof of pregnancy and treats me as a sperm donor. I agree despite my guilt, but after days of secret sex and creampies, our incredible chemistry gradually makes her fall for me instead.
