I guess some things are instinctively learned as one of my hands travelled down to cup my mum’s voluptuous ass while the second moved up to cup her ...reast. I almost came on the spot. The breast was so incredibly soft and tender to knead. I inserted my hand underneath her skirt and was surprised to see that she wasn’t wearing any panties. Her ass was so tender and sweet to hold on to. From the corner of my eyes, I could see Aaron undressing himself with Anna already naked on the floor. Aaron’s. Then she let out one final cry and relaxed. I pulled away from her, removed my finger and gave her vagina a final lick and stood up, admiring her firm dark brown body."Shall we shower then?" I asked her."Can I suck you off first?" she replied."If you like," I replied, my penis already starting to become erect again from licking her.

"Did I do that?"I really wanted the earth to open up under my feet and swallow me."Well it certainly wasn't Mr. Patel mum, was it?" I can't believe that," she giggled."Mum, for Christ's sake." and she shut up, or at least she turned away, but her shoulders were shaking, and I was damn sure she wasn't crying this time!By the time she'd turned round again, my embarrassment had solved the problem and there was no longer an obscene bulge in the front of my shorts."Aw come on Tommy don't be grumpy.
