Trunks is a little lost in the sensations himself, despite his normal good sense. And normal shyness, as no one's caught them yet to remind him to be embarrassed. The part of his brain that would normally be alert to this is not in charge however.

Which doesn't mean his brain isn't working--he's spent too long having to be alert for his life and for other's lives to be completely lost.

But most of his attention is taken by Cassie. Her lips, and occasionally her tongue, as they kissed. Sharing breath, and he could hear her heartbeat faintly. Of how close she was--maybe not as soft as some women, but still softer than him for all that she was toned muscle which he appreciated. Warm, and he just wanted to keep her close. And maybe to explore, although he kept a firm leash on that impulse regarding his free hand not holding the box.
