Why a teenage girl was enjoying sex with an old man i just wondered

An unexpected scene i saw when i watched a teenage girl was was happily enjoying sex with an old man then i sure she must be a slut hence i started watching them silently from a window where every scene was seen. Many times i watched porn movie but when i got real porn then i set my eyes on them.

While watching toward them my dick was getting hard erected like a rod because I desired to get between them but I controlled and keep watching their fucking act. Dick of old man was thicker and bigger than me which that teen girl was enjoying into her last depth of pussy hole and keep enjoying fucking in every style non-stop.
