When I was in college, I went home with a female friend to do some work for her grandma, whose husband had died about 10 years previous. Her grandma was still pretty nice (being 60). Since I lived about 30 miles from her, and she liked the work I had done, she asked if she could call on me when she needed other things done. I said sure. After about the 4th visit, I was really sweaty and she offered to dry me with a towel, almost similar to this. She got turned on by touching, said she had been without since her husband had died, and she missed the sex. Long story short, we tried it once to see how it would work out... we both liked it and I continued to "see" her for the next 3 years while I was in college.
