Well while it was a joke the title is very very fitting considering this series is going.
BTW the actual titles so far are: 【ゆっくりエロス】胴付きゆっくりちぇんを・・・ (Chen) 【ゆっくりエロス】胴付きゆっくりまっちょりーを・・・ (Man-Patchy) 【ゆっくりエロス】胴付きゆっくりしずはを・・・ (Shizuha) 【ゆっくりエロス】胴付きゆっくりみのりこを・・・ (Minoriko) 【ゆっくりエロス】胴付きゆっくりゆうぎを・・・ (Yuugi)
After the "胴付きゆっくり" nonsense it branch out to something different.
