Kasumi enjoys watching you two

As Sarah pushes your hands down, you look over and lock eyes with Kasumi.

She smiles at you, and slowly reaches her hand down her skirt.

Your eyes get big in surprise. You're moaning now involuntarily from Sarah's unrelenting wetness enveloping your dick.

Seeing you eagerly watching her next move, Kasumi starts rubbing her clit. "More" you utter.

Sarah, thinking you're talking about her, increases the pace.

Kasumi reaches up and pulls off her top, then undoes her bra, letting her small brown nipples flow out. Seeing your excitement, she pulls off her skirt and lays back on the bed.

Both of your heads are now turned. You're both staring lustfully at the other. Then, Kasumi starts fingering herself and let's out a gasp.
