Fuck her vaginally

You mounted Mariko from behind and slid into her completely, earning a small moan from her. Gripping the sheets, she managed to say, "That's right...fuck me!"

Obliging, you began pumping into Mariko nice and hard, just the way she liked it. In addition, her moans began to grow in intensity as you fucked her harder.

Squeezing both her asscheeks, you began to pick up the pace while Mariko teased her clitoris. Your movements became so erratic that your climax was clearly inevitable.

Mariko was the first to climax, and you soon followed suit by pulling out and ejaculating all over her ass. She gives you a wicked grin before turning around and licking your cock clean.
