Just the presence of others makes his heart race, and hiding under the futon leads to full-body contact, skin sticking tightly together, instantly triggering a full erection. Trapped inside due to the sweltering heat, they press their sweat-soaked bodies close, muffling moans while engaging in slow, deep thrusting. A forbidden affair with a patient hidden from a senior nurse, a massage client sneaking around the innkeeper, or NTR sex right beside their sleeping partners—the fear of getting caught creates intense excitement, triggering the arousal effect like the "bridge phenomenon," sending desire into overdrive. Each squishy impact of her divine breasts sends shockwaves through his cock, amplifying pleasure uncontrollably until he can't hold back anymore.
