One time I tried to use an apple as an onahole, but it was an unpleasant experience for two reasons:
-The apple was very solid, so using it to masturbate was less pleasurable than simply masturbating with my hand
-I was afraid of carving a hole too large in the apple, hence rendering it unusable as an onahole... So the hole I carved was too small, and I ended up breaking the apple with my PENIS.

If anybody knows of a fruit that's pleasurable to fuck, feel free to inform me about it ヽ(´.｀)ノ

btw: no, I didn't eat the apple after ejaculating with it
