Eventually we all ended up in the lounge in bathrobes and the evening wound down to point where tiredness started to creep over us all. We offered the... boys the opportunity to sleep with us but they politely declined and got dressed ready to leave. Innocent kisses were exchanged on the doorstep and it was quite a sad moment when the three of us stood in Angela’s porch and waved as our studs departed. “Well that’s that,” I said philosophically. “That’s the downside of a takeaway, once it’s gone.

Besides, it would be good for them to experience.
