I talked to a beautiful woman with moderately muscular proportions who was doing stretching exercises in the park. - Her name is Kozue-chan (24 years old) and she is an instructor at a nearby gym. - She stretches a lot while she speaks. - As expected, she takes care of her body maintenance, and she runs home every day after her work. - She will cooperate with the shooting on the condition that she will be rewarded if she gives a private lesson as guidance on stretching exercises and muscles. - When the shooting starts, I immediately ask her to take off so that I can see the muscles well. - Purunpurun big breasts were hidden under her jersey. - I asked her to teach me how her pectoral muscles work and started massaging her breasts. - When she puts the vibrator directly into the crotch of Kozue who is getting more and more comfortable, she raises a pant voice similar to a scream and repeatedly shouts "I'm going! Iku!". - While being impressed by the sensitivity that exceeded her expectations, I threw the cock erected in Gingin with a polite blow job into the slimy pussy. - Even so, her Kozue-chan's amazing hip movements were good. - I want everyone to see her happy face!
