Tease her

Ren said nothing, instead squeezing Makoto's ass through Ann's clothes.

"Oh!" Makoto giggled. "Touch all you want, Ren!"

She adjusted herself so Ren could get easier access to her tits and ass. Ren groped her tits a bit harder than he did her ass.

"What would Makoto think if she saw us, huh?" Makoto asked in an impression of Ann's seductive voice. "I'd bet she'd yell at you. Call you names. Probably get mad at me."

She leaned in closer. "But Makoto's not here right now, is she?"
