I got excited by the tight pants she was wearing during a fitness session and got a hard on... The instructor, who realized this, seduced me by showing off the leggings that were digging into her plump ass! She rubbed my rock-hard cock between her fleshy ass and did whatever she wanted! She reverse-fucked my big cock, which had reached the limit of its desire to penetrate, in an instant! She manipulated my external anal sphincter freely and skillfully tightened it, squeezing out my sperm over and over again with her miraculous anal sex!
