[Ushichichi Bokujou (Mikan Gyuunyuu)] The Alien Cowgirl 2

A towering alien cowgirl with curling horns teases her tiny human companion, offering her impossibly huge breasts and asking, "How does my boobs feel compared to mil's? Hm?" as she drowns him in her overflowing milk. She dominates every encounter, gleeful and bossy, commanding "Jump♥ jump♥ up and down, we go♥" while her victim can only gasp "Ah♥ ah♥ ah♥… me too…" beneath her squelching, lactating weight. By the end she wears a satisfied smirk, deciding "He's still somewhat punished♥ I think I'm starting to take a liking to Hitomi♥ hehe," while her swamped partner floats, blissfully ruined, in the deep valley between her breasts.
