Using Girlfriend's Mother's Panties to Masturbate for the First Time

This was back when I was 17, and my girlfriend's family had a medical emergency. It wasn't anything serious looking back, but when I first heard the news of the family heading to the emergency room on a Saturday morning, I rushed over there and skipped work but was unfortunately greeted with a policy that only allowed immediate family in the emergency room, as it was going to be hours worth of patients ahead of her. I chatted over the phone, and was asked for a favour, to go to their house and feed their dog. At this time it was already mid-afternoon, and they said it was looking like a late night discharge. 

Of course, I headed over and visited my favorite dog to let her use the backyard and get her legs running. I stayed with her until dinner time, feeding her the kibble and prescribed medicine as directed. The sun set and it was just me in the house all alone, with an eerie feel. I called the mom again, asking for an update and possible ETA. The only information I got was that they haven't even been seen yet, and it would most likely be another couple of hours, and plenty of thanks for staying late to give the dog some companionship. I told her I would stay at least until her final bathroom session later tonight so she wouldn't soil in the house. 

I sat there with the TV on, before the realization hit me. It was a little nerve wracking, as I slowly pushed the master-bedroom door open, and flicked on the light. I immediately went over to draw the blinds as I remember the view I could see into this window from the street. I wasn't worried about someone walking in on me, as I could very easily tell when someone drove into the driveway, let alone opening the garage door. However, I was scared that the very bright light that slipped through the cracks in the blinds would easily alert the family if they came home, giving the indication that I was in the room. 

I hastily made quick excuses in case they did come home unexpectedly, but my horniness overrode any logical thought of being caught. My girlfriend's mom was very pretty for her age. I wouldn't say she was the stereotypical milf you see in movies or porn, but she was definitely cute, with a wider ass, flat stomach, and bigger chest. She was very active and her skin was amazingly tanned as always. She had naturally blonde hair that she dyed brown, and her smell was amazing. 

I went straight for the hamper first, pleased to find a small pile of worn clothes in the bottom. She had recently done her laundry, but I pulled out 3 pairs of worn panties, two cotton panties, a fullback and a cheeky cut pair. Along with a lace thong with a nice cotton gusset. The thong was the real prize, clearly just worn as the crotch was still damp but cold, the grool not yet crusty from this morning. The other two pairs were older and had less scent, but still wonderful to have nonetheless. 

I swapped focus to the drawer, pulling out a heavy drawer from an antique dresser. Panties basically fell out as I opened it, freshly laundered on top was the pairs from her most worn rotation. Most were simple cotton panties, but from the middle and bottom I pulled out more skimpy g-strings, satin panties, and thongs. While not at the top of her collection, these were well worn, vintage victoria secret, hanky panky, and la vie en rose. The tags were all worn off, some were barely hanging on by threads. She must have had these since she was in her 20s. 

The next hour was a real eye-opener for me. I spent my time slipping on each pair, trying on as many different styles and materials. I loved how the soft fabric would hug my balls, cupping them as I slowly jerked off. I was careful not to accidently cum, which was actually harder than I thought. I soaked many of her pairs in my precum, leaking from my head, begging to release its contents over the pile of panties. I loved the thongs and strings as they dug up my ass, teasing my anus with the soft fabric. I managed to even find a nice pair of garters, which felt amazing as I slipped them on my legs, clipping them to the garter belt. As a straight man, it felt weird to be turned on by the feeling of being feminine. I imagined the mom spreading my legs before eating my ass and sucking on my cock, running her hands up and down my legs feeling the smooth nylon from the thigh highs. Before I could help it, I realized I was laid down on her bed, thong tightly stretched over the head of my cock and splitting my balls apart. The tight fabric wedging up my ass as I stroked harder. The wet thong from her hamper only got more wet as I indulged in her tangy grool, imagining her thick thighs planting down over my face as I ate her hairy pussy out. I couldn't hold it back anymore as I had a spasm and orgasmed, cumming straight through the thong, absolutely soaking the thong before splattering the rest on my belly. 

I laid there with the thong in my mouth, savouring in the remaining taste as my cock softened. Before cleaning up, I went for round two, wrapping the other worn panty around my cum soaked cock, mixing our two sexes together. The cum re-soaked her crusty grool, and soon enough I was jerking with a soaking mess in the crotch of the panty. I slipped the head of my cock into the gusset gap, and stroked furiously, imagining her slipping on this pair, unknowing that my cum was inside already. I came again, much less this time, but the panty was completely soaked anyways. I decided to keep the worn thong as a souvenir, paired with a couple old gems from her drawer.
