Tribbing

Red hair and black hair brush against one other other as their vaginal lips caressed each other.

Karai held April's leg up just over her shoulder as she ground her pelvis against April's.

If April wasn't so overwhelmed and coated in sweat, she would admire just how muscular her girlfriend was. She looked relatively svelt fully-clothed, but her ninja girlfriend/lover had an actual six-pack, and her muscular thighs were made for this specific sex-act, if nothing else.

April wasn't obese or even fat, but her body wasn't as fit as Karai's, not having dedicated her life to martial arts or any kind of sport. Karai didn't mind. In fact, it made April's body much softer. Not to mention it gave her ass the perfect curvature.
