A turkey baster.

Venus stands up and says, “I have an idea.” She walks slowly into your kitchen, so as not to drip any cum onto the floor. She rummages around for a while and then comes back with a turkey baster in her hand.

You look at her questioningly. She just smiles and waves the turkey baster over herself. You watch in amazement as the cum on her body streams off of her and into the utensil.
It is almost completely full before the last drops fly inside. You must admit to being rather proud that you are now able to jizz that much!

Venus dances provocatively before you, sucking on the end of the baster and rubbing it on her tits, ass, and pussy. She then lays on her back on the floor, spreads her legs and points them at the ceiling. You go and stand next to her to get a better angle to view the action, jacking your hard cock as you do so.

Venus shoves the narrow end of the baster into her pussy. Slowly she pushes it deeper and deeper until only the bulb is outside of her. She squeezes the bulb hard and you can literally hear the squelching noises of your cum as it squirts out inside her.

You watch her pussy pulsate as cum dribbles out of her full cunt. Your cock is throbbing with heat and desire at the bizarre display. Venus says, “It takes a great deal for a mortal to impregnate a Goddess. I’m just making sure none of your precious man milk is wasted.”

“It looks like you’re full up.” You say and point at the cum leaking out of her pussy.

“Oh, there’s always room for more cum.” Venus says with a dreamy look in her eyes. “I love feeling it inside me.” She takes out the baster and starts to play with her clit. “I love it so much!” Venus seems to be a mild orgasm just by the feel of your cum inside of her!

Venus’s pussy does seem kinda full, maybe that would make for an interesting sensation, or maybe you should try something else, another hole perhaps?
