Would you like to 'swap' with a couple consisting of an S1 actress and an AV actor? Based on this theme, we will be sending out "Yua Kuramochi" for the first time. Two couples participated. The relationship between the couple has become so strained that it cannot be improved... They take off everything and boldly switch partners! Jealousy, confusion, excitement... an intense swap where all kinds of emotions intersect. After enjoying a different cock and pussy than usual, you will see the good side of your partner. S1 is looking forward to your swap requests!
