[Amashoku] Oneechan ni Norou!! (Ama Shota) [MrBubbles]

Takkun never asked to be mounted by his sadistic Mii-nee, but the busty older girl rides him like a pony, whip in hand, and demands he worship her huge breasts and satisfy her insatiable pussy until she's had her fill. What starts as teasing her shy, glasses-wearing partner spirals into a battle for dominance—she takes him deep into her sensitive butt while he desperately tries not to blow his load, secretly aching to make her his and only his. By the final page she's the one addicted to his riding, promising sugar-cube rewards and the whip of love as their sweet days of confirming feelings stretch on.
