Watching my mother get bred by a old drunk

I was watching tv in my mom’s friends apartment, he was older than her at the time, but nice, they were drinking beer in the late morning and her friend had bought me some cool stuff from Woolworth s and I was good, but at some point I looked behind me and saw my mom French kissing this older guy…I just turned back around to watch more tv…I heard them talking lower than before…then some time passed and I heard the bed springs ( his tiny apartment was a studio open room) creaking loudly…I looked behind me again and I saw my moms older friend on top of her completely naked on top of her who was also naked completely, he was holding himself up on his fists with arms straight thrusting his hips back and forth in and out of her pussy…I thought it was funny cause his beer belly kept smacking against her…she had her legs splayed and she started moaning louder, as his thrusting became fast, ‘ slap, slap, slap,slap,slap!,,’ was the sound, my mother turned her head and saw me watching and told me in husky sternness, “ Turn around and watch tv!” I did immediately but soon turned around to look again…he turned her around and started pounding her from behind making the loud smacking noises, ‘ Slap, slap,slap, slap,’ she was moaning in a way that made my genitalia feel tingly and I saw him grab a hand full of her blonde hair and fucked her pussy from behind while holding her hair and she let out a gutteral moan that I can still remember and get turned on by to this day…he must of cum in her cause it stopped abruptly and my mother got up and went to the bathroom with a large beach towel between her legs and holding it up against her pink breasts…
