HUNTC-049 "It's wetter than usual..." NTR in the kotatsu! Having intense sex with my best friend's girlfriend in the kotatsu without him noticing!

In front of a close friend, secretly having intense sex with his girlfriend in the kotatsu without getting caught! Suppressing my voice to endure the pleasure, but it feels even better than usual, her place is soaked, emergency situation declared! The more I think about getting caught being bad, the tighter she squeezes me, unable to hold back and performing deep penetration! Furthermore, unable to hold back any longer, she, while her boyfriend is seemingly asleep beside her, seeks me out for a maximum taboo sex act of adultery where neither of us can make a sound! Women are scary…
