Def: “Frottage is a physical act that takes place between two people of either the opposite or the same sex involving the contact of genitals against genitals. The genitals of the two participants are interlocked as they rub against each other with the intent of arousing sexual desire. The genital stimulation produces increasingly pleasurable sensations; if it is done for significant enough time and the partners are sufficiently aroused, orgasm will result.”
J and I began our relationship doing vagina – penis frottage many years ago. I used to call it “buttering her muffin”. Sorry, what can I say …… I was 22 years old. I would lie on my back and she world straddle my hips and nestle my shaft lengthwise against her vagina so that my cockhead would rub on her clit. She became very adept at rubbing her clit on my shaft, eventually moving her clit to my cockhead when she was just about ready to cum. She loved to see me ejaculating thick streams of my cum on her erect clit. She was a master at timing our orgasms.
