可愛いけどちょっぴりおせっかいな腐れ縁の幼馴染・芽依から「セックスの練習相手になってほしい！」とまさかの相談！コンドーム一つを手に、ぎこちない手つきで始まるセックスの練習開始。1回のハズが、セックスの気持ちよさに目覚めた芽依が絶倫化！？ずーっとイキ足りなくて休憩なしの10発射精。フェラもクンニも中出しもこんなに気持ちいいなんて…両親不在の3日間。タガが外れた幼馴染の2人は、ゴム無しセックスの虜になってしまう。
My hood friend Mei—who’s cute but a bit of a busybody—shockingly asks me, “Will you be my practice partner for sex?” With just a single condom in hand, our awkward sex practice begins. It was supposed to be just once, but Mei, awakened to the pleasure of sex, becomes insatiable!? She can’t get enough and makes him cum 10 times straight without a break. Blowjobs, cunnilingus, and creampies—I never knew they could feel this good… With our parents away for three days, the two of us—our hood friends—lose all restraint and become addicted to bareback sex.
