You're on holiday with mom and the rest of the family and mom thinks she might be starting to burn in the sun, so she calls you over to help rub lotion on her. Having your hands all over your mom's curves ends up getting your cock hard, and mom notices. But she's not mad, she's apologetic for putting you in an awkward situation, and suggests the two of you go inside and chill in the hot tub where the rest of the family can't see what's happened. When you get in the tub, it's still not going down, so mom suggests you just "sort yourself out" so she can get back out in the sun. You're too shy to just pull it out in front of her, so she takes her top off to make you feel at ease. You still can't believe mom wants you to jerk yourself off with her right there! But as it turns out, mom's actually got an even filthier idea in mind...
