You're in the middle of wedding planning when you get a phone call from your beloved step-mommy. She's not doing too well because her research is about to get defunded. You'd never suspect your own step-mother is trying to get you away from your fiance- but when you come over, she asks if you'll help her with her experiment, because she only needs one more participant.

You're in the middle of wedding planning when you get a phone call from your beloved step-mommy. She's not doing too well because her research is about to get defunded. You'd never suspect your own step-mother is trying to get you away from your fiance- but when you come over, she asks if you'll help her with her experiment, because she only needs one more participant. She's studying...birth control and tells you she's extremely confident nothing will happen. You've sorta always thought about what it would be like to fuck your step-mom, but you're unsure. "No one will know. The participation is confidential." Talk about unethical- but your step-mom just took off her lab coat and her lingerie is amazing. Why not just this once? So she doesn't lose her life's work. She shows off and you end up fucking your step-mom in missionary and ending with a HUGE creampie. She is so thankful. But months and months and months..about 8.. went by, so much wedding planning, and you haven't been able to get a hold of your step-mom. The day before the rehearsal dinner she finally calls you. "Sweetie, I'm going to need you to call off the wedding." Turns out Step-Mommy is the jealous type and she wasn't studying birth control, she was studying fertility treatments. Step-Mommy is pregant!
