Stepmother's surprise as I accidentally swallow Viagra and she offers assistance

I was at my stepmom's house and she caught me sneaking some Viagra from her stash. She was not pleased but offered to help me get the pill down. I took a swig of water but as soon as I put the pill in my mouth, she started to suck on my tongue, her hands roaming over my body. I was completely taken aback, but she was insistent on helping me swallow the pill. As I finally managed to choke it down, she let me know that this was just the beginning. She was ready to show me how good it could feel to have a hard dick pounding her. I was more than willing to let her take control. As she got on her knees in front of me, I could see the anticipation in her eyes. She unzipped my pants and took my throbbing cock into her mouth, sucking and licking it with an intensity that I had never experienced before. It was a sight to behold as she took me deep into her throat, her big ass bouncing with each thrust. The feeling of her mouth on mine was enough to push me over the edge and I shot my load all over her face, cum swapping with my stepmom.
