This is their 13th, no 69 so far.
A Chinese couple get married - and she’s a virgin. On the wedding night, she cowers naked under the bed sheets as her husband undresses. He climbs in next to her and tries to be reassuring: “My darring, I know dis you firt time and you flighten... I plomise you, I give you anyting you want, I do anyting you want. What you want?” “I wanna numma 69” she replies. “You wanna beef with bloccolli?”
