Outside.

As turned on as you were, there was no way you were coming inside your mother. You draw the line at fucking her.

Hitting orgasm, Clarisa spreads her legs as wide as she can, releasing you from their grip, trying to tempt you and your seed into the depths of her passion.

Taking advantage of this, at the last moment, you pull out, firing all you have over her chest and stomach, covering her in sperm.

With legs still spread, even if lower onto the worktop, she lies panting, trying to recover from her orgasms.

"Come on, honey!" She groans, still rather out of breathe, "That was a good chance you wasted. Now, the closest I'll get to birthing our third kid will be washing your sperm out of my nightie."

Disappointed with the outcome or not, you took a strange pride in the fact she seemed to enjoy it. Though, you quickly realise that you need to scoot. You aren't who she thinks you are.
