Hell yeah!

"The first most important thing is the endurance training." You turn Gohan around, pulling her tail and lifing her skirt, to see her cute little ass, fresh and tight, awaiting you.

"Stop at once!" Yells Chichi. You laugh.

"Of course I would. But I couldn't resist if she nicely asked me to go on." You say, pulling the tail in your hand. Gohan moans, looks at her mother and whispers.

"P-please go on"

The human doesn't know what to do. You however do know. You remove the cloth from around your crotch, revealing your juicy Saiyan cock. You rub it against that cute little ass, before shoving it right into her.

Loud moan. You use her tail as some sort of handle. As you start thrusting into her, the tail pulls her back right onto your cock. And she loves it. Every thrust, that made her virgin hole go wider and wider. You're taking her virginity AND her mind.

Chichi, though she would never admit, was enjoying it. She fought bravely not to move her hand to her crotch. But like every weakling, she failed. She was now masturbating to the sight of her own daughter sexually pleasing an stranger.

Gohan's insides were squeezing around you tightly, trying to keep you in. Soon, her love juices squirted all over the ground. You slowed down, but just a little.

"The test proves your endurance sucks. We need to go another round" You grin, going back to full speed. Her moans grow louder.

"N-no, you can't! I-I just... M-mom, say something!"

"You better leave her..." Chichi managed to talk inbetween moans. "... After this round."

"As you wish." You smile, clapping those cute little asscheeks. Is this what Earth feels like? You're definetelly staying there for way longer.

As you plan what more to do with them later, your cock gets ready to ejaculate.
