You lift your mother up from kneeling and press her against the shower wall, feeling up her great, luscious tits and rubbing your palms on her swelling nipples. "I'll be even happier if you let me into that tight little pussy of yours." You then mash your lips against hers, kissing her roughly.
Your mother pushes against your chest and breaks the kiss, turning away. "But, {firstname}, you're my son! That's incest! That's wrong!"
"And sucking me off, swallowing my cum, and getting pasted all over your body isn't just as much incest and just as wrong?" you ask, interested to see how she justifies herself.
"That was just a bit of fun. It wasn't intercourse! Besides, Dad wouldn't let us bring contraceptives down here. I could get pregnant!" she says, her shock apparent on her face.
"That's a great idea, too," you say as you use your knees to spread her legs apart. You step between them and drop your hand down to her slit. You rub your fingers in her and find her very wet and slippery. Mom whimpers at your touch.
What do you do now? Let her go? Convince her? Force her?
