You glance over at Natsuki, who's watching you intently. Her cheeks flush at the suggestion, but there's a gleam in her eye that tells you she's not entirely opposed to the idea. With a nod from Yuri, Natsuki steps forward, her own arousal plain to see as she kneels down beside Monica and takes your cock into her mouth as well.

The feeling of two eager mouths sucking on you at once is overwhelming, sending waves of pleasure coursing through your body.

As if sensing that you're close to cumming, Natsuki takes things a step further. She lowers her head and begins sucking on your testicles, her warm mouth engulfing them completely as she expertly rolls them between her lips and teeth. The sensation is incredible, driving you even closer to the edge.

"Ohhh," Monica moans around your cock, "she's so good at that."
