The thing about sex is a long sensual foreplay - with lots of kissing, stroking, fumbling and fingering. But also a massage of neck, back and hot old ass from grandma is very erotic horny. To then sit on her butt with a stiff cock between the cheeks to knead the back is a hot feeling and also the pre-cum sticks between the ass cheeks to the pinched rosette. Fucking is only done later, even if the butthole offered itself in the posture. Then her hairy mature cunt is fingered from behind until orgasm comes. Hammer ass and wet cunt are fun to play with.
