今度は海で!温泉旅館で!ヤンママ姉貴と浮気三昧の二泊三日!

育児のため実家に帰省中の姉(25)がエロすぎて、ある夜酒の勢いでセックスしてしまった弟の俺。
それからというもの子持ち人妻ボディの抱き心地が忘れられず姉の肉体に溺れる日々。

はじめは弟の性欲処理のため仕方なく…という態度だった姉も、
最近では積極的に俺との浮気エッチを楽しんでくれるようなってきた(気がする)。

そんなある夏の日、俺は商店街の福引で「豪華熱海旅行券」をゲット。
なんと姉一家+俺+両親みんなで家族旅行へ出かけることに!?

熱海といえばビーチも温泉もあるリゾート地。
ビキニで浴衣で混浴でとエロいロマンが盛りだくさん!

旦那に甥っ子、両親たちもすぐ側にいるけれど…
もはやガマンなんてできるはずがなくて!?

My sister is a young mother breastfeeding in Atami

This time at the beach! At a hot spring inn! Two nights and three days of cheating with a young mom sister!

My younger sister (25) is returning to her parents’ house to raise her child, so I’m a younger brother who has had sex one night with the energy of drinking.
Since then, I can’t forget the comfort of a married woman with a child and I end up drowning in my older sister’s body.

At first, her younger sister had no choice but to relieve her younger brother’s sexual desires.
Recently, he has been actively enjoying having sex with me (I feel like it).

One summer day, I got a “luxurious Atami travel voucher" at a lucky draw in the shopping district.
The sisters and my family + me + parents all go on a family trip!?

When you think of Atami, you’re a resort area with beaches and hot springs.
There are plenty of erotic romances, such as a bikini and a yukata bathing in a mixed bath!

My husband, my nephew, and my parents are right next to me…
There’s no way I can hold back anymore!?

This is a manga + CG collection where you enjoy cheating sex at the beach or hot spring inn while traveling with your young mommy sister during a family trip.

*This work is a sequel to “My Sister is a Young Mama Breastfeeding in My Parent’s House."
