Claimed by His Best Friend

I was covered by his long trenchcoat, desperately shaking. Carnival crowd packing together. His hand inside my shirt. Hard, erect cock grinding my ass. My fiancé was less than three meters away from us. One turn of his head—he would see my panties already ripped off. Suddenly, front crowd crashing violently. I lost my balance and stumbled backward into his embrace. That fatal hardness, using the crowd’s shove, sliding deep inside me. Without any warning.
