Opposites complement each other (Part 1) R-18 

While Aster was making Aria melt with kisses and caresses, Alice caught a glimpse of the water undulating at a certain specific spot, her bright red eyes saw through the steam and her hand sneaked under the water.

Aster slightly opened his eyes, feeling her soft touch on his dick, but after gazing at Alice who looking away as if she was feigning ignorance about the fact that she was stroking his hard hot thing, he inwardly smiled and closed his eyes again as he kept kissing Aria.

Having gotten the "green light", Alice giggled as she increased the sped of her hand, making sure to rub the whole shaft.

Needless to say, but her hand job was clumsy at the best, normally if she wanted to please him, without engaging into intercourse, she would use her mouth, she has even tried to do it with her breasts since they grew to fit her brother's liking.
