A different kind of sensation
Calvin was just like any other 18 year-old, beating off to one of his porn magazines. He always liked his women to be much older than him. that was until he became one when the Great Shift occurred and caused him to swap bodies with 64 year-old, Marge down his street, and to make matters worse she was in the middle of masturbating as well. Already experiencing the sensations from their new bodies, both Calvin and Marge continued masturbating in each others bodies. Marge, now a horny, porn addicted teenage boy and Calvin, now a horny granny with his hands in his pussy.
