SCOP-599: 旦那とのマンネリSEX打開目的で膣トレをしている義母をたまたま目撃！！普段意識していなかったが義母のイヤラしいカラダとエッチな格好にフル勃起！！しかも膣を鍛えているせいか締まりも最高！！若い欲求を抑える事が出来ず禁断の関係に！！

I happened to witness my mother-in-law doing vaginal training for the purpose of breaking out of a rut SEX with her husband! I wasn't usually conscious of it, but I got a full erection with my mother-in-law's unpleasant body and naughty clothes! Moreover, the tightness is the best because the vagina is trained! !! - I can't suppress my young desires and I'm in a forbidden relationship!
