My mom and I go to JC Penney so my mom can buy a pair of jeans

My mom and I go to JC Penney so my mom can buy a pair of jeans, at the JC Penney store my mom was looking at the women's jeans, she picked out three pairs of women's jeans that she liked, I accompanied my mom to the dressing room, she removed her shoes and the jeans that she was currently wearing, she took the new pair of women's jeans that she liked off of the hanger, she put the new pair of women's jeans that she liked on, I said "Mom you look good in those women's jeans" she said "Thank you Josh" I grabbed my mom's crotch and said "I want to make sure that the women's jeans that you're trying on have plenty of room in the crotch" as I was grabbing and feeling my mom's crotch, I felt my penis start to get hard, I was grabbing and feeling my mom's crotch, then I said "Turn around I want to see how those women's jeans look in the butt" she turned around, I said "Looking good, turn back around so I can resume grabbing and feeling your crotch", I resumed grabbing and feeling my mom's crotch, I unbuttoned unzipped the women's jeans that she was wearing, I inserted my hand into her midnight black Vanity Fair Illumination string bikini panties and said to her" Mom your crotch is getting wet" I felt my penis get harder by the minute I said "Mom I am going to end up ejaculating in my black Hanes Her Way satin bikini panties".
