普段から無防備な義姉が最近ピラティスにハマって恥じらいもなく四つん這いで尻を突き出したり谷間を晒したり…家の中が超エロい環境に！いくら身内とは言えそんなに見せられたら思わずフル勃起！さらにガマンの限界で我を忘れてお尻を鷲掴みして挿れてしまった…。あまりの気持ち良さに即発射してしまうボク。それでも治まらない勃起チ○コを見て今度は義姉が発情！さっきのは足りない！と言わんばかりに再挿入を求めチ○ポにしゃぶりついてきた！1回発射して正直満足だったボクだけど、あまりにもエロい義姉のおかわり要求にチ○ポもビンビンに！

My sister-in-law, who is usually quite uninhibited, has recently become obsessed with Pilates, and without any shame, she's been getting on all fours, sticking her butt out and exposing her cleavage… making our house an incredibly erotic environment! Even though she's family, seeing her like that made me instantly get a full erection! I couldn't hold back any longer and lost control, grabbing her butt and thrusting into her… It felt so good that I came immediately. But my erection wouldn't subside, and now my sister-in-law got aroused! It was as if she was saying, "That wasn't enough!" and started sucking on my dick, demanding to be inserted again! I was honestly satisfied after coming once, but my sister-in-law's request for more was so erotic that my dick became rock hard again!
