Cum Inside.

You're about to blow and there's only one place for you to put it, as deep into your mother as you possibly can.

With one final thrust, Clarisa's legs spread wide, her vagina tightens and you empty your balls right into her.

The two of you bask in orgasmic bliss, while she plays with her erect nipples. Slowly sliding out of her, you sit on the floor, trying to catch your breath.

"That was amazing, Logan!" She mutters, to exhausted to talk, "With this, a third is definitely going to be on the way."

A third? You realise you might be a future father of your own sibling; but you've got to get away before she works out you're not your father.
