神様お願い！お兄ちゃんの赤ちゃん妊娠したいの！ ～ツンデレ妹＆清純妹とエッチなキセキでトラブル子作り三昧♪～

Sweet Chise is sporting and cheerful, whilst Airi is a prickly tsun-tsun type with small breasts.

Both of these little sisters love their big brother and want to marry him!

Who will he choose? They're both trying hard to sway his opinion, given their personalities.

Really the only way to decide is to have sex with them... separately and together!
