When your son comes home from a friends house with a hard cock that won't go down and he has no idea why. I asked what did you take and he told me it was a blue pill that his buddy gave him. And then he said his cock got hard and won't go down. I explained to him that his friend had given him a viagra and laughed. But I had to help him so I pulled out his cock and started sucking and stroking before sitting him down and bouncing my ass back on his throbbing cock. Then he bent me over and fucked me doggystyle before laying on the bed and fucking me on the edge of the bed. I had him get on the bed so that I could ride him reverse cowgirl so he could see mommys ass pounding back on his cock. He couldn't hold it much longer and blew his load in mommys pussy.
